ABSTRACT
This report provides a statistical analysis of waste production by Concawe member company refineries in 2013, based on survey data returned from 74 member company refineries (71% response rate) situated in the EU-28 countries + Norway and Switzerland. It includes a breakdown of waste tonnage according to the origin of the waste, how it was managed and how it was classified under the 2008 Waste Framework Directive (2008/98/EC). This findings from the survey, together with those of previous Concawe waste surveys for 1993 (Concawe; 1-95) and 1986 (Concawe; 5-89), show how the sector has responded to developments in EU waste legislation over the past 30 years. In addition, the data constitute a modern baseline for the future assessment of performance. Total waste production reported by the refining sector in 2013 was 1.2 million tonnes, of which 43% was classified as hazardous. The top 3 reported hazardous wastes types by tonnage are sludges (comprising tank bottoms, physical/chemical treatment, biological treatment and other), followed by spent chemicals/acids/bases and then contaminated soil/stones/aggregate/concrete (with approximately one third of these arising from remediation activities). The top 3 non-hazardous wastes comprise soils/stones/aggregate/concrete, followed by metal and biological wastewater treatment sludges. Soils/stones/aggregate/concrete constitute 65% of the total non-hazardous waste reported, while metal and biological wastewater treatment sludges constitute 9% and 4%, respectively. The vast majority (94%) of refinery wastes were disposed within the country of origin, with only spent catalyst exported outside the EU (to specialist recovery facilities). Recycling accounted for the largest waste tonnage (34%), followed by waste going to landfill (20%). This is in contrast to the 1993 survey, which found that landfill accounted for 40% and recycling 21%. In parallel, the percentage of waste used for energy recovery reduced from 15% in 1993 to 7% in 2013, while the percentage of waste disposed of by incineration reduced slightly from 8% to 6%. These findings demonstrate that the sector has been successful in moving waste streams up the EU waste hierarchy, with an increasing proportion of waste going to recovery, recycling and re-use. Legislative changes and associated changes in waste reporting practices mean that the 1993 and 2013 data on refinery waste tonnage and handling costs are not directly comparable. For example, the apparent increase in total waste tonnage from 1993 to 2013 may well reflect more systematic waste classification and reporting under the 2008 Waste Framework Directive. The total cost of refinery waste management appears to have significantly increased, from an inflation-adjusted figure of approximately 80 M$ in 1986 (for 89 refineries), to 137.2 M$ in 2013 (for 74 refineries).

SUMMARY
This report presents the findings from a survey undertaken by the Concawe special taskforce on refining waste (WQ/STF-36) to determine the quantity of waste managed by Concawe member company refineries in 2013. The report includes a statistical analysis of waste production, handling costs, management options and the tonnages reported under different primary European Waste Catalogue codes (Annex of Commission Decision 2000/532/EC, as amended by Decisions 2001/118/EC; 2001/119/EC and 2001/573/EC) and Waste Hazard codes (Annex III of Directive 2008/98/EC).
The 2013 survey questionnaire was distributed to all 104 refineries operated by Concawe member companies. 74 refineries responded to the questionnaire which gave a response rate of 71%. Total waste production reported by the refining sector in 2013 was 1.2 million tonnes, of which 43% was classified as hazardous. The vast majority (94%) of refinery wastes were disposed within the country of origin. The only waste exported outside the EU was catalyst for recovery.
The top 3 reported hazardous wastes types by tonnage are sludges (comprising tank bottoms, physical/chemical treatment, biological treatment and other), followed by spent chemicals/acids/bases and then contaminated soil/stones/aggregate/concrete (with approximately one third of these arising from remediation activities). Sludges constitute 45% of the total hazardous waste reported, while spent chemicals/acids/bases and contaminated soil/stones/aggregate/concrete constitute 14% and 12%, respectively. The top 3 non-hazardous wastes comprise soils/stones/aggregate/concrete, followed by metal and biological wastewater treatment sludges. Soils/stones/aggregate/concrete constitute 65% of the total non-hazardous waste reported, while metal and biological wastewater treatment sludges constitute 9% and 4%, respectively. The focus on control of emissions to land and water, and soil remediation is evident in the fact that sludges from wastewater treatment and oil-impacted soil/stone/aggregate/concrete wastes together account for 53% of total reported hazardous waste.
The total reported waste tonnage in 2013 is split across seven different waste management option groups, with recycling accounting for the largest proportion (34%) followed by waste going to landfill (20%). This is in contrast to the 1993 survey, which found that landfill accounted for 40% and recycling 21%. In parallel, the percentage of waste used for energy recovery has reduced from 15% in 1993 to 7% in 2013, while the percentage of waste disposed of by incineration has reduced slightly from 8% to 6%. The main waste management option in 2013 for hazardous waste was treatment (24%), with the remaining tonnage split fairly evenly across the other management options. For non-hazardous waste, recycling was the dominant management option (49%), followed by landfill (29%).
Approximately 75% of the total hazardous or non-hazardous waste, and therefore, the majority of the waste classifications used in the industry are accounted for by the top 10 waste classification codes reported. Of the waste classified under these top 10 codes, the vast majority was disposed of in their country of origin and none was exported outside of the European community. With the exception of asbestos (hazardous waste landfill), there were no instances of codes for special types of waste being restricted to a single waste management option.
The median cost of all hazardous waste management (316 $/tonne) is similar to the median country group cost for Baltic, Benelux and France. In Central Europe and

VII
Iberia the median cost is lower, at 63 $/tonne and 85 $/tonne, respectively, whereas in Germany, Mediterranean and UK & Ireland the median cost is closer to 500 $/tonne. The median cost of all non-hazardous waste management (83 $/tonne) is similar to the median country group cost for Baltic, Central Europe and Iberia. In Benelux and Germany the median cost is lower at 20 $/tonne, whereas in France, Mediterranean and UK & Ireland the median cost is closer to 200 $/tonne.
There is regional variation in waste management options for major waste types. This is observed, for example, when it comes to waste management of sludges. Landfill is an important management option for hazardous sludges in the Mediterranean, and for non-hazardous sludges in the Mediterranean and Iberia. Incineration and energy recovery are widely used for both hazardous and non-hazardous sludges. An important waste management option for non-hazardous sludges in Germany and UK & Ireland is use for land improvement. A significant fraction of hazardous sludges in the Baltic, Benelux and Germany areas are disposed of by recycling (possibly used as feedstock for coking units). While the data gathered in this study does not provide insight into the reasons behind such differences, possible explanations for the variation include differences in the interpretation of waste legislation across the EU Member States, and that more than one waste classification code can be used for a certain types of waste.
Legislative changes and associated changes in waste reporting practices mean that the 1993 and 2013 data on refinery waste tonnage and handling costs are not directly comparable. For example, the apparent increase in total waste tonnage from 1993 to 2013 may well reflect more systematic waste classification and reporting under the 2008 Waste Framework Directive. The total cost of refinery waste management appears to have significantly increased, from an inflation-adjusted figure of approximately 80 M$ in 1986 (for 89 refineries), to 137.2 M$ in 2013 (for 74 refineries).

1. INTRODUCTION
Ongoing developments in European waste management policy (e.g. 2016 revision of Waste Framework Directive (WsFD, 2008/98/EC)1 and the circular economy initiative), have the potential to significantly impact refinery waste management practices and costs. In order to better understand the possible consequences of policy change, Concawe has compiled an inventory of waste production and management at member company refineries.
Concawe has carried out surveys of waste production at member company refineries in 1986, 1993, and most recently in 2013. The number of respondents has fluctuated over the years, but has generally exceeded 70%. The 2013 survey questionnaire was distributed to all 104 refineries operated by Concawe member companies, with the response rate being 71%.
The objectives of the latest Concawe waste survey, which was completed in 2015 for refinery operations in 2013, were as follows:
i. To provide initial baseline data on European refinery waste classification and management under the WsFD (2008/98/EC), the previous Concawe waste survey having been completed prior to the implementation of this directive (in 1993).
ii. To develop an improved understanding of regional differences in waste classification and management, and also exemptions for ‘by-products’.
iii. To demonstrate changes over time in refinery waste production and management practices
iv. To provide information that could be relevant concerning adoption of the Classification, Labelling and Packaging (CLP) criteria to waste classification
v. To examine the consistency of application of the List of Waste classification (often referred to as the European Waste Catalogue or EWC) codes assigned to refinery wastes
vi. To understand whether waste classification varies between National Regulatory Authorities, potentially leading to a non-'level playing field' for resource management
While objectives iv, v and vi were addressed by the data collection exercise, the associated data analysis and reporting requires additional time and resources, and so is not included in this report.
Data was also collected on the production of non-waste by-products, however the quantity of data returned was not sufficient to perform a sector-relevant analysis.
This report shows the findings from the 2013 waste inventory, which includes a statistical analysis of waste production, handling costs, management options and the tonnages reported under different List of Waste (EWC) codes (Annex of Commission
1 Directive 2008/98/EC of the European Parliament and of the Council of 19 November 2008 on waste and repealing certain Directives

Decision 2000/532/EC2, as amended by Decisions 2001/118/EC3; 2001/119/EC4 and 2001/573/EC5) and Waste Hazard codes (Annex III of Directive 2008/98/EC).
The findings from the 2013 survey, together with those of previous Concawe waste surveys for 1993 (Concawe; 1-95) and 1986 (Concawe; 5-89) provide insight into how waste generation and management has changed in Europe over the past 30 years.
Note: The data presented in this report has been compiled through the best endeavours of Concawe member companies, and has been checked for consistency and outliers. Notwithstanding the above, complete checking of the data returns is not possible and so for this reason, the data presented should be considered indicative rather than absolute.
1.1. WASTE HAZARD PROPERTIES AND CODES.
Properties of waste which render it hazardous are listed in Annex III to the Waste Framework Directive (2008/98/EC). Each hazardous property (e.g. “flammable”, “toxic”, etc.) is assigned a unique individual code.
This report references the Waste Hazard codes (H1 to H15) assigned according to the legislation in place at the time that the data collected for this report was generated (2013). Since then, Commission Regulation (EU) 1357/20146 replaced Annex III to the WsFD with an updated list of waste hazardous properties and a new coding structure (HP1 to HP15). The replacement of Annex III to Directive 2008/98/EC changed the basis for waste hazard classification from the use of risk phrases and associated substance threshold concentrations specified in the EU Dangerous Substances Directive (67/548/EEC)7 and Dangerous Preparations Directive (1999/45/EC)8 to the use of hazard statements and associated substance concentrations specified in the EU CLP Regulation (EC 1272/2008)9. This has resulted in changes to definitions and to substance concentration thresholds for some waste hazardous properties and as such it is important to note that direct translation

2. DESIGN OF 2013 SURVEY QUESTIONNAIRE
The 2013 survey, which was issued in June 2014 in MS Excel spreadsheet format, comprised three data input worksheets, as follows:
Identification and contact
Information on Wastes
Information on Non-wastes
The blank 2013 survey questionnaire template is provided in Appendix 1.
2.1. IDENTIFICATION AND CONTACT
Under “Information and contact” the following site details were collected: Company name, Refinery name and location, Ownership, Contact name, Contact details, JV-partners, and Type of site.
The type of site was entered by selection from a dropdown box, with the options being as follows:
Refinery, Refinery and crude oil terminal, Bitumen plant, Lubricant plant, Combined refinery and chemical plant, and Other (as specified)
Data on refinery capacity and feedstock throughput was collected via a parallel 2013 Concawe survey questionnaire on refinery effluent quality and water consumption, which was also issued in June 2014. When no data on capacity and throughput was provided, the nameplate capacity of the installation and/or a statistical evaluation based upon the sector's 2013 performance and earlier data submission for the installation were used to estimate a throughput.
2.2. WASTES
Respondents were requested to provide data on all refinery wastes10, whether produced directly by the reporting member company or by contractors undertaking work on their behalf. The “Waste” worksheet comprised a single table for the entry of data on refinery hazardous and non-hazardous waste production and management, with the following column headings:
Waste Classification (EWC) Code (entered by user)
Waste Type (selected from a dropdown list, as shown in Table 1)
Waste Source (selected from dropdown list, as shown in Table 2)
Waste Producer (to indicate if waste produced by refinery or a contractor)
Total amount of waste produced (entered by user, units of tonnes)
Final Recovery or Disposal route (selected from dropdown list, as shown in Table 3)
10 Data was also collected on the production of non-waste by products, however the quantity of data returned was not sufficient to perform a sector-relevant analysis

Location of Final Recovery or Disposal (two options: Exported within European Community (including NO & CH); Exported outside the European Community)
Waste Hazard codes (“x” entered by user under applicable listed H codes H1 to H15)
Additional Comments
It was requested that separate rows of data should be entered for each unique combination of waste classification (EWC) code / waste type / waste source / waste management option (final recovery or disposal route) and location (of final recovery or disposal). EWC codes reflecting hazardous waste types are indicated with an asterisk (*).
In addition to the waste-type specific information listed above, refineries were asked to provide the total cost (in M$) of hazardous and, separately, non-hazardous waste management in 201311.

3. ANALYSIS OF SURVEY DATA
The statistical analysis of data captured by the 2013 refinery waste survey was performed by Newfields Consultants (US). Data provided in the survey questionnaires was first extracted into a MS Access database and then structured to facilitate quality assurance checks and data analysis. The data was analysed to provide insight into:
Variation in production and management practices for hazardous and non-hazardous refinery wastes (as defined by EWC codes) across different European regions (as defined by country groups).
Variation in total hazardous and non-hazardous waste management costs across different European regions.
Any regional variation in the classification of refinery waste types and application of EWC codes and Waste Hazard codes.
Whether waste/non-waste classification varies between National Regulatory Authorities, potentially leading to a non-'level playing field' for resource management.
In this report hazardous waste is defined as waste reported with a waste classification code containing an “*”, and/or waste reported with a hazard code (H1 to H15 at time of survey in 2013). Note that following data quality assurance checks, some wastes reported as non-hazardous were reclassified as hazardous, and vice versa (see Section 3.1 below).
For the purpose of analysing the survey data, waste management options were grouped as shown in Table 4. Groups were established to reflect, where possible, the waste hierarchy (c.f. Figure 11). Note that for two groups the final waste management option in the hierarchy is not clear, e.g. “Multiple Disposal/Recovery methods” and “Treatment”. This is discussed further in the Opportunities for Improvement (Section 11).

3.1. DATA QUALITY CHECKS
A total of 77 questionnaires were received as a result of refinery sites with multiple operational facilities. Refineries that returned more than one questionnaire (showing different parts of the facility operation) were aggregated into one site for analysis. Refineries provided data for the operation year 2013 except for one refinery, which provided data for 2012.
The following Quality Assurance and Quality Control (QA/QC) checks and corrections were performed:
Cost data were requested in US dollars. In some instances, survey responders provided cost data in their local currency. In these cases, cost data were converted to consistent units of US dollars. When converting from a different
report no. 12/17
9
currency, the average historical conversion rate in 2013 was utilized12. Specific conversion rates used include: 1 Euro = 1.33 US Dollar and 1 PLN = 0.282 US Dollars.
Outlier testing was performed using cost per tonne as a normalizing basis. Follow-up requests were sent to refineries to confirm or clarify outlier costs and/or quantities. When applicable, values were changed in the database based on responses. All changes were documented along with valid reasoning for each change and preservation of the original respondents’ input.
Based on respondent notes, some waste types were converted from “Other” to more descriptive categories. For example, some refineries commented that waste classified as “Other” was spent batteries which was subsequently changed to “Waste Electrical & Electronic Equipment (WEEE).”
Some waste totals were provided as volumetric measures. These were converted to a consistent tonnage basis by using specific gravity or density values cited from on-line sources. Specific conversions included: o Number of fluorescent tubes to tonnes assuming each fluorescent tube was
269 g.13 o Cubic meters of waste oils to tonnes assuming a specific gravity of 0.88
g/cm3.14 o Cubic meters of polystyrene to tonnes assuming a density of 1.04 g/cm3.15 o Cubic meters of waste water to tonnes assuming a density of 1 g/cm3.
Concerning reported Waste Classification codes: o Consistent formatting was applied. Leading zeros were added to maintain
the 6-digit format of the codes. o An asterisk “*” (indicating a hazardous waste) was added to codes
associated with hazardous waste types, where it was clear that this had been accidentally omitted.
o In some instances, when filling in the questionnaire, responders inadvertently added an asterisk “*” to codes reserved for non-hazardous wastes. If the waste stream indicated hazardous material via the notes or hazardous code listing then the code was adjusted to the appropriate hazardous code. If the waste stream did not indicate any hazardous material, then the asterisk was removed from the reported code.
o If a reported code did not match with an actual existing code then, where possible, the correct code was chosen based on the waste stream type and additional notes or information provided by the refinery. If the correct code could not be determined the data was excluded from the analysis.
All data changes resulting in the QA/QC procedure were fully documented in the database.
3.2. DEFINITION OF COUNTRY GROUPS

were investigated by plotting the tonnages of different waste types aggregated by country group, in accordance with the data analysis structure shown in Figure 2 below. Plots were also produced showing waste management options for the top 10 hazardous and non-hazardous waste types by total tonnage (see Appendix 2).
Note: Where no tonnage was reported for certain waste category/ waste source/ waste type combinations, the corresponding box on the flowchart (Figure 2) has been removed and no plot is provided in Appendix 2.
Note: Waste category/ waste source/ waste type combinations represented by only 1 tonnage record are shaded light grey in Figure 2, with the writing in italics.
3.3. DATA AGGREGATION
Waste data is presented both in terms of total waste tonnage (reflecting the environmental burden) and also tonnes per kilotonne of feedstock throughput (as a measure of efficiency). Where relative waste production data has been aggregated, data from individual refineries has been weighted according to their feedstock throughput.

4. WASTE QUANTITIES AND SOURCES
Of the 77 survey questionnaires returned, all included data on non-hazardous waste tonnage and 71 included data on hazardous waste tonnage. A total of 68 refineries provided tonnage data for both hazardous and non-hazardous waste (three questionnaires were not taken into account in the number of total refineries, since for two refineries sub-facilities reported independently; in the first case three sub-facilities were merged into one refinery and in the second case two sub-facilities were merged into one refinery).
4.1. WASTE PRODUCTION (TONNES)
Total reported waste production by the sector in 2013 was 1.2 million tonnes, of which 43% was classified as hazardous (Figure 3). Reported waste production across the country groups was broadly similar, although the ratio of hazardous to non-hazardous waste was somewhat lower for the country groups Benelux, UK & Ireland and Central Europe. Various factors may account for this, for example regional differences in how waste legislation is implemented. Future surveys may show if this is a meaningful trend that merits further analysis.
Figure 3: Total hazardous and non-hazardous waste partitioned by country grouping
Figure 4 shows the final waste management location of wastes, whether disposed in country, exported within the European community, or exported outside of the EU. The vast majority (94%) of refinery wastes were disposed of within the country of origin. The only waste exported outside the EU was non- hazardous spent catalyst.

Figure 6: Total Non-Hazardous Waste separated by source partitioned by country grouping
Based on the reported Waste Classification (EWC) codes, non-hazardous waste production in Central Europe was dominated by dredging spoil and soils/stones, which accounted for 81,000 tonnes (52%) of the total. Waste reported from “Other” sources is primarily soil and construction waste from investment projects or reconstruction works, as shown in Table 6. The “Other” category was chosen to reflect that these wastes are from civil engineering projects (e.g. railway renovation), and not remediation or turnaround events16.
16 The “Other” waste source category contains some EWCs that may belong to a more specific category. For example, in some questionnaires EWC 050103* (Tank bottom sludges) are reported under “Other”, however sludges can usually only be extracted after emptying the tank. This being the case, it may be that these would be better reported under the “Major events (e.g. Turnaround)” category. Similarly, EWC 100101 (bottom fly ash and dust) and 100105 (calcium-based reaction from FGD system) may be better reported under the “Refinery operation” category.

4.2. RELATIVE WASTE PRODUCTION (TONNES/ KTONNE FEEDSTOCK THROUGHPUT)
The effect of normalising hazardous and non-hazardous waste production to refinery feedstock throughput is shown on Figures 7 and 8. While the degree of variation in relative waste production is less than that in total waste tonnage, significant differences remain between the country groups. For hazardous wastes the range in relative waste production across the country groups is 0.44 to 1.99 tonnes/ kilotonne feedstock throughput, with a sector average of 1.07 tonnes/ kilotonne feedstock throughput. For non-hazardous wastes the range in relative waste production across the country groups is 0.59 to 2.66 tonnes/ kilotonne feedstock throughput, with a sector average of 1.45 tonnes/ kilotonne feedstock throughput.
It is important to note that because the survey is a snapshot in time, waste totals for certain country groups may be dominated by large one-off projects. This is especially the case for wastes associated with construction, demolition and remediation. For this reason, differences in relative waste production between country groups do not reflect differences in overall waste management efficiency. For example, at the high end of the range for relative non-hazardous waste production is Benelux, which reported 96000 tonnes of non-hazardous soil/stone/rock wastes from remediation and refinery operations (>50% of total reported waste for the Benelux country group).

Figure 9 shows that the top 10 hazardous waste types account for 83% of both total and relative waste production. Figure 10 shows the same for the top 10 non-hazardous wastes, however for non-hazardous wastes the top 10 waste types account for 91% of both total and relative waste production. Wastes on the left-hand side of the plots are most important in terms of mass produced and therefore potential candidates for further research into waste reduction.
The top 3 reported hazardous wastes types are sludges (45%, comprising tank bottoms, physical/chemical treatment, biological treatment and other), followed by spent chemicals/acids/bases (14%) and then contaminated soil/stones/aggregate/ concrete (12%, with approximately 4% arising from remediation activities). The focus upon minimising emissions to water soil remediation is evident in the fact that sludges from wastewater treatment and oil-impacted soil/stone/aggregate/concrete wastes together account for 53% of total reported hazardous waste.
The top 3 non-hazardous wastes comprise soils/stones/aggregate/concrete (65%) from construction and demolition activities and remediation, followed by metal (9%) from major events, demolition and ongoing maintenance, and biological wastewater treatment sludges (4%).

5. WASTE MANGEMENT
5.1. WASTE HIERARCHY
The Waste Framework Directive (2008/98/EC) sets out a waste hierarchy, or priority order of what constitutes the best overall environmental option in waste legislation and policy. This hierarchy is illustrated in Figure 11 below.
Figure 11: EU waste hierarchy
A key objective of the EU legislation is that member states implement measures to encourage waste producers to move waste streams up the waste hierarchy, such that the percentage prevented, re-used or recycled is increased. In the analysis of the 2013 waste data the reported waste management options have been grouped to reflect this hierarchy, as shown in aforementioned Table 4. The groupings also permit comparison with the 1993 waste survey, which used a similar (though not identical) grouping.
5.2. MANAGEMENT OPTIONS FOR HAZARDOUS AND NON-HAZARDOUS WASTES
Figure 12 and Table 7 show the tonnage and percentage of hazardous and non-hazardous wastes assigned to the management option groups. Table 7 also shows the percentage of total waste assigned to these management option groups in the 1993 and 2013 surveys. It should be noted that accurate comparisons are not possible because slightly different method grouping were used in the 1993 and 2013 surveys. For example, waste management by “treatment”, which accounted for 12% of total waste in 2013, was not an option in the 1993 survey. Also, the 1993 survey had the waste management options “alternate fuel use” and “landfarm”, which accounted for 1.7% and 4.9%, respectively, in the 1993 survey. While acknowledging the difference in the 1993 vs 2013 waste management option groups, some observations can be made concerning apparent changes in waste management practices:
Landfill use has reduced significantly, from 40% of total waste in 1993 to 20% in 2013. Even if all waste sent for treatment was assumed to be landfilled (and not composted or incinerated with/ without energy recovery) this still represents a significant reduction. In parallel, the percentage of waste recycled has increased from 21% to 34% over the same period, showing the progress made by the
report no. 12/17
22
refining sector over the past 20 years towards moving waste management up the waste hierarchy.
The percentage of waste used for energy recovery has reduced from 15% in 1993 to 7% in 2013, while the percentage of waste disposed of by incineration has reduced slightly from 8% to 6%. It should be noted, however, that these figures may be distorted if wastes sent for treatment are ultimately disposed of by another route, such as energy recovery. More detailed information would be required in future survey questionnaires to provide a breakdown of the final waste management options utilizes post ‘treatment’.
For hazardous waste, the main management option in 2013 was treatment (24%), with the remaining tonnage split fairly evenly across the other management options. For non-hazardous waste recycling was the dominant management option (49%), followed by landfill (29%).

5.2.1. Geographic variation in hazardous and non-hazardous waste management options
Figure 13 shows that there are regional differences in the management option for major waste types, which could reflect the availability of waste management options and local policy differences. For example, landfill disposal is more important for non-hazardous waste in Iberia, Germany, Mediterranean and UK & Ireland country groups. Options to divert non-hazardous waste away from landfill require that additional recycling facilities are available locally to make this feasible. In France and Central Europe energy recovery is more utilised, but initiatives on raw materials could further promote this option.

5.3. VARIATION IN WASTE MANAGEMENT OPTION ACCORDING TO WASTE TYPE
The reported management options for the top 10 waste types (in terms of tonnage) were analysed to establish the extent to which refineries may be reliant on particular management options. The results of this analysis for hazardous and non-hazardous wastes are shown in Figures 14 and 15.

Additional plots are provided in Appendix 2 showing the management options for the top 10 hazardous and non- hazardous wastes types, split by country group. Note that the interpretation of this data is sometimes difficult due to the high tonnages reported under the ambiguous “treatment” and “multiple/ other” management options (e.g. hazardous tank bottom sludges, hazardous soil/ aggregate/ concrete, hazardous sludges (other) and also non- hazardous domestic sewage treatment sludges). Where this is not an issue, the plots in Appendix 2 provide insight into the dominant waste management options per waste type.
5.3.1. Hazardous wastes
A number of management options are reported for the top 10 hazardous wastes, with energy recovery, multiple/other and treatment being the main management options and smaller tonnages sent for incineration or to landfill (Figure 14). The percentage sent to landfill exceeds 5% for only 2 out of the top 10 hazardous wastes, these being soils/stones/aggregate/concrete (20%; corresponding to 2.4% of total hazardous waste tonnage) and “other” (25%; corresponding to 1% of total hazardous waste tonnage).
Recovery options dominate for materials where significant value can be realised such as catalysts, oils, acids, chemicals and higher calorific value sludges.
5.3.2. Non-hazardous wastes
The top 10 non-hazardous wastes are dominated by soils/stones/aggregate/concrete and metal, which together account for 69% of the total tonnage (Figure 15). 54% of soils/stones/aggregate/concrete waste was recycled, with 38% sent to landfill and 8% to multiple/other management options. Metal waste was either recycled (>95%) or sent for treatment (possibly prior to recycling).
With reference to Section 5.1.1, the single largest waste tonnage sent for landfill disposal, which could potentially move up the hierarchy, is non-hazardous soils/stones/aggregate/concrete. Additional work would be required, however, to better understand the opportunity for increased re-use of this material, taking into account legislative constraints and the infrastructure available in member states.

6. WASTE CLASSIFICATION CODES AND WASTE HAZARD CODES
The European List of Waste, often referred to as the European Waste Catalogue (EWC) is a hierarchical list of waste descriptions established by Commission Decision 2000/532/EC for use in waste characterization prior to waste management. Individual wastes are assigned a unique six figure code, with each having a description to match with the waste. Waste codes suffixed by an asterisk “*” are always hazardous waste. Survey questionnaire respondents were asked to report the EWC code and also the applicable Waste Hazard codes in place during 2013 (see Section 1.1) for each reported waste type, as shown in Table 8. The full List of Waste is available at:
http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=uriserv:OJ.L_.2014.370.01. 0044.01.ENG

specialist infrastructure required for its waste management is not present in all EU Member States. With exception of asbestos (hazardous waste landfill), there were no instances of EWC codes for special types of waste being restricted to one management option. Items marked as having a “Multiple/Other” management option were most often managed with a combination of recycling and energy recovery. In addition, some waste streams in this category were managed through incineration.

Figure 18 shows the tonnes of hazardous waste that were assigned a specific Hazardous Waste code by the survey respondent (H1-H15 at the time the survey was carried out). Many respondents listed multiple hazardous waste codes for their wastes. The graph applies the total waste tonnage to each of the multiple listed codes. Therefore, the sum of individual waste tonnages was larger than the actual total waste quantity. The hazard category “Not listed” reflects the fact that not all countries require Hazardous Waste codes to be listed on the transport document (requiring only a distinction between hazardous vs non-hazardous).
Hazardous Waste code H14 (ecotoxic) is applied to more waste than any other Hazardous Waste code. Work being undertaken by the European Commission to develop and implement common criteria at EU level to determine whether waste possesses an ecotoxic hazard may impact the amount of waste assigned this hazard. In addition, implementation of updated hazardous waste definitions and threshold limits for certain hazardous waste properties introduced by Commission Decision Regulation (EU) 1357/2014 may further impact the distribution shown.

7. WASTE MANAGEMENT COSTS
In the 2013 survey refineries were asked to provide data on the total annual cost (in K$) of hazardous and, separately, non-hazardous waste management. A breakdown of total costs was not requested due to the commercial sensitivity of such information, and as such significant variation is likely in the approach used for the cost calculation (especially the extent to which indirect costs are included). For these reasons the findings from the cost data analysis are considered indicative rather than absolute.
7.1. TOTAL REPORTED COST OF WASTE MANAGEMENT
Of the 77 survey questionnaires returned, 57 included data on hazardous waste costs and 58 data on non-hazardous waste costs. In addition, 5 questionnaires were returned with aggregate waste costs (hazardous + non-hazardous). 63 questionnaires (representing 61 refineries) were therefore available for the summation of EU refining sector waste management costs.
Total reported waste management costs in 2013 were 137.2M$, with hazardous waste management accounting for 91.7M$, non-hazardous waste management for 34.7M$ and undifferentiated (aggregated hazardous + non-hazardous) for 10.8M$.
7.2. VARIATION IN HAZARDOUS AND NON-HAZARDOUS WASTE MANAGEMENT COSTS
Figures 19 and 20 show the rank order of the hazardous and non-hazardous waste management costs per tonne of waste, respectively, for individual refineries. For these graphs, the cost provided by each site for the given hazardous or non-hazardous category was divided by the computed total tonnage of waste in the same category. Refineries were then ranked from lowest to highest cost per tonne waste and plotted on a logarithmic scale. Not all reporting refineries provided cost information, as noted above. A high outlier in the hazardous plot that does not fit the main cost distribution is indicated in red. This has been excluded from subsequent box plots as it is considered to reflect unresolved errors in the reported data (average hazardous waste management cost of > 25,000 $ per tonne is unrealistically high).

Figure 21 shows a box-and-whisker plot of the distribution in hazardous and non-hazardous waste costs per tonne (left hand plot), and per ktonne feedstock throughput (right-hand side plot), respectively. Figure 21 also includes the legend to all box-and-whisker plots shown in this chapter. Two sites had a relatively high cost per tonne for hazardous waste management (~3000 $/tonne). Comments returned in the questionnaire indicated that for one of these sites the cost includes the dewatering of waste water treatment sludge. Sludge dewatering represents an additional cost and could also increase the cost per tonne, if the dry rather than wet sludge mass was reported. For this site the cost normalized to feedstock throughput is below the industry median, which is consistent with this hypothesis. For the other site no supporting data was provided, and so the reason for the high cost per tonne is not clear. However, in this case also the cost normalized to feedstock throughput is below the industry median.
An analysis of the one site on the right hand plot that had relatively high cost per ktonne feedstock throughput for hazardous waste management (~6000 $/ktonne feedstock throughput) indicated that the largest waste stream from this site was related to fly ash due to electrostatic precipitator (ESP) abatement of the pet-coke firing combustion plant. It cannot be determined, however, if this waste stream is responsible for the high cost per tonne feedstock throughput.

7.3. WASTE MANAGEMENT COSTS BY COUNTRY GROUP
For hazardous waste, the median cost of waste management (316 $/tonne) is similar to the median country group cost for Baltic, Benelux and France. In Central Europe and Iberia the median cost is lower at 63 $/tonne and 85 $/tonne respectively, whereas in Germany, Mediterranean and UK & Ireland the median cost is closer to 500 $/tonne (Figure 22). Possible explanations for these differences include different levels of availability of each waste management option between countries, country policy and economic instruments concerning specific waste management options and location of refineries relative to waste management facilities.
The Baltic and Germany country groups exhibit much wider variations in hazardous waste management cost than other country groups, whereas the variations in relative waste management cost is clearly the widest in the Mediterranean area. For some countries the prevalence of a specific waste management option is shown in Figure 24; in Central Europe and France there is high utilisation of energy recovery, in Benelux recycling, in Germany material recovery and in UK & Ireland incineration.
For non-hazardous waste the median cost of all waste management (83 $/tonne) is similar to the median country group cost for Baltic, Central Europe and Iberia. In Benelux and Germany the median cost is lower at 20 $/tonne, whereas in France, Mediterranean and UK & Ireland the median cost is closer to 200 $/tonne (Figure 23). Possible explanations are similar to those provided for hazardous waste (see above).
The Baltic and Mediterranean country groups exhibit the widest variations in non-hazardous waste management cost, whereas the median relative waste management costs are generally in the range 10-90 $/ktonne, except where influenced by high outliers (e.g. the Mediterranean area at 200 $/ktonne). Figure 25 shows significant recycling in Benelux, Central Europe, France, Baltic and Mediterranean and use of landfill in Germany, Iberia, Mediterranean and UK & Ireland.
Further to show the management options for hazardous and non-hazardous wastes in different areas, Figures 24 and 25 show the 25th and 75th percentile of the cost per tonne indicated above each bar. Detailed cost information for each waste management option would be a valuable addition to future surveys, to provide insight into factors driving the wide variation in waste management costs

8. VARIATION IN WASTE MANAGEMENT OPTIONS FOR MAJOR WASTE TYPES
This section considers in greater detail regional variation in waste management options for selected high tonnage wastes.
8.1. SLUDGES
Refineries produce large quantities of sludge, principally from tank cleaning and wastewater treatment, as described in Section 4.2. The total mass of sludge produced by the 74 refineries reporting in 2013 was 296,809 tonnes; a percentage breakdown of this tonnage is provided in Table 9 below. Given the high tonnage, there is a potential for further research into cost effective waste minimisation and/or to move the waste management option higher up the waste hierarchy. This, however, would require a detailed analysis of sludge production and management, which is not possible based on the data collected in this study.
The total sludge mass is equivalent to an average of 1 tonne of sludge for 1390 tonnes (i.e. 0.07%) of refinery feedstock throughput, which is 2.8 times lower than the sludge production reported in 1993 (1 tonne per 492 tonnes feedstock throughput; 0.2%). This apparent reduction could be due to a number of factors, for example increased dewatering of sludges prior to waste management (no data was collected on sludge water content). With reference to Table 9 below, the majority of the sludge tonnage is derived from tank bottoms and physical/ chemical/ biological treatment of waste waters.
Table 9: Percentage contribution of reported sludge types to the total reported sludge tonnage in 2013.
Sludge type Sludges
(%) All Waste
(%)
Sludges - Tank bottom 26.2 6.7
Sludges - Desalter 1.7 0.4
Sludges - Alkylation 1.0 0.3
Sludges - Boiler feed water 2.4 0.6
Sludges - Domestic sewage treatment 3.6 0.9
Sludges - Interceptor (API, CPI, etc.) 1.8 0.5
Sludges - Wastewater physical/chemical treatment (DAF, IAF, etc.) 23.3 6.0
Sludges - Wastewater biological treatment 23.5 6.0
Sludges - Other 16.5 4.2
The sludge types recorded in the 2013 survey, as shown in the table above, together account for 45% of total hazardous waste and 10% of total non-hazardous waste. The majority of the total sludge tonnage (79%) was classified as hazardous waste, although a proportion of WWTP physical/chemical and biological sludges were classified as non-hazardous.
In the case of physical/chemical treatment sludges, 6% of the total tonnage was reported as non-hazardous. This comprised mainly boiler feedwater sludge (EWC 050113). 11% of biological wastewater treatment sludges were reported as non-hazardous, comprising sludges from on-site effluent treatment [non-hazardous]
report no. 12/17
40
(EWC 050110) and sludges from other treatment of industrial waste water [non-hazardous] (EWC 190814).
8.1.1. Geographical variation in waste management options for different sludge types
Figures 26 and 27 show the variation in waste management options for hazardous and non-hazardous sludges, split by country group. Incineration and energy recovery are widely used for both hazardous and non-hazardous sludges. Landfill is a significant waste management option for hazardous sludges in the Mediterranean, and for non-hazardous sludges in the Mediterranean and Iberia. The reported “recovery-other” management option for non-hazardous sludges in Germany and UK & Ireland is “R10 - Agriculture/ecological benefit” (i.e. use of sludges for land improvement).
A significant fraction of hazardous sludges in the Baltic, Benelux and Germany areas is recycled. While not explicit in the survey returns, sludge recycling appears to correlate with refineries operating coking units, which can use oily dewatered sludge as a feedstock. For example, sludges with high oil content may be injected into a delayed coking unit during the coking phase so that they are converted to coke and liquid coking products. High water content sludges can then be used to quench the coke during the quench phase of the coking cycle.
As previously mentioned, where waste management is by “treatment” or “multiple/other”, information on the final management option was not collected in the survey. This situation may be encountered when waste is taken away by a contractor for treatment prior to waste management. Addressing this issue will be important for future surveys but is acknowledged to be difficult as it may, at least in some cases, require access to the records of refinery waste management contractors.

8.2. OILS
Table 10 shows the tonnage of each EWC code used for the reporting of waste oils. It is apparent that a large part of the total tonnage may reflect waste containing only a small amount of oil (e.g. “wastes containing oil”; “water from oil/water separators”). A more explicit definition of waste oils would help to avoid this confusion in future surveys.
Table 11 compares the total tonnage of waste oil in each geographical region to the corresponding tonnes of feedstock throughput. Only a very small percentage of the total refinery feedstock throughput (0.0045% on average over all country groups) was disposed of as waste oil.
Figure 28 shows the waste management options of reported hazardous waste oils in different country groups, in units of tonnes and also tonnes waste/ktonne feedstock throughput. The dominant waste management option in absolute and relative terms was recycling, closely followed by energy recovery. A minor component of the total tonnage (approximately 500 tonnes) was sent for incineration. The remaining tonnage was reported under the treatment/ multiple (other)/ not specified categories, whereby the final waste management option was not captured by the survey.

8.3. CATALYST
The regeneration and recovery of spent catalyst requires specialist facilities that may not be available in the country of origin. Accordingly, hazardous and non-hazardous waste catalyst accounts for 25% and 29% of the refining waste that was exported within the European community in 2013.
Figure 29 shows the waste management options for hazardous and non-hazardous spent catalyst, split by country group. The majority of spent catalyst is sent for recycling, treatment or recovery, with a small amount (4788 tonnes; 6%) sent to landfill or for incineration.

Acids, bases and spent chemicals, also require specialised regeneration and recovery facilities that may not be available in the country of origin. Accordingly these wastes account for 46%.of the refining waste that was exported within the European community in 2013.
The 14,811 tonnes reported sent for recycling and 9,784 tonnes reported sent for treatment in Benelux all came from individual refineries. The same holds for the 22,694 tonnes reported as sent for “recovery-other” in Germany. This indicated that the high tonnages for Benelux and Germany is more related to specific operations of individual refineries than representative for a whole country group.
The category spent chemicals was identified to be a non-optimal category naming since different survey respondents interpreted it differently. For the next survey questionnaire the category referring to chemical waste needs to be more clearly defined and explained.

8.5. SOIL/ STONES/ AGGREGATE/ CONCRETE
Figure 31 shows the management options of reported hazardous soil/stones/aggregate/concrete waste, split per country groups. As previously discussed (see Section 4.2), the reported tonnage of this waste type is highly dependent on the site-specific timing of remediation, major turnaround events, and investment projects. Figure 32 indicates that the majority of soil/stones/aggregate/concrete waste is from non-hazardous remediation and major turnaround events. The main management options for this waste type were “recovery-other”, “recycling”, and “multiple/other”. Hazardous soil/stones/aggregate/concrete waste is typically treated for the purpose of reuse or to remove the hazardous properties to enable waste management via other options. A small tonnage of this waste type was used for energy recovery; from the reported EWC codes it can be seen that this fraction comprised hazardous soil and earth (90% dredging spoils and 4% soils; no further detail was provided).

9. COMPARISON OF REPORTED WASTE TONNAGE AND MANAGEMENT COSTS IN 1986, 1993 AND 2013 SURVEYS
Table 12 provides a comparison of the 1986, 1993 and 2013 waste surveys in terms of the number of reporting sites, total and relative waste tonnage and cost.
A high level comparison of waste tonnage indicates an increase in total and, in particular, relative waste production from 1993 to 2013 despite the number of reporting refineries decreasing from 89 to 74. The increase may be associated with a higher tonnage of material being classified as waste under current EU legislation (e.g. E-PRTR (Regulation EC No. 166/2006) and the Waste Framework Directive (2008/98/EC)). It may also reflect a real increase in waste production due to enhanced emission control measures (e.g. increased use of three-stage wastewater treatment and consequent rise in biological sludge production, increased use of ESP to remove dust from flue gases or an increase in the tonnage of material removed during remediation activities). In parallel, the total cost of refinery waste management also appears to have increased, from an inflation-adjusted figure of approximately 80 M$ in 1986 to 137.2 M$ in 2013.
An in-depth comparison of the 2013 survey and previous survey data is not possible due to changes in the reporting metrics used. For example, hazardous and non-hazardous wastes were not separately classified in the 1986 and 1993 surveys. The 2013 survey also includes significantly more detail on sources of wastes, waste management options and waste types. To protect confidentiality, only total costs of waste management were requested in the survey. Consequently detailed comparisons of costs is not possible as the scope of the cost calculation may vary between sites (for example, whether waste transport costs are included).

10. CONCLUSIONS
10.1. ANALYSIS OF SURVEY DATA
The 2013 survey questionnaire was distributed to all 104 refineries operated by Concawe member companies. 74 refineries responded questionnaire which gave a response rate of 71%.
10.2. WASTE QUANTITIES AND SOURCES
Total reported waste production by the sector in 2013 was 1.2 million tonnes, of which 43% was classified as hazardous. The ratio of hazardous to non-hazardous waste was somewhat lower for the country groups Benelux, UK & Ireland and Central Europe. The reasons for it being lower in some country groups can be plenty (e.g. regional differences in how legislation is implemented), and future surveys may show if this is a meaningful trend that needs to be further analysed. However, it is important to note that because the survey is a snapshot in time, waste totals for certain country groups may be dominated by large one-off projects.
The vast majority (94%) of refinery wastes were disposed of within the country of origin. The only waste exported outside the EU was non-hazardous spent catalyst.
For hazardous wastes the range in relative waste production across the country groups is 0.44 to 1.99 tonnes/ kilotonne feedstock throughput, with a sector average of 1.07 tonnes/ kilotonne feedstock throughput. The highest relative waste production is reported in Central Europe, while the lowest is in UK & Ireland. For non-hazardous wastes the range in relative waste production across the country groups is 0.59 to 2.66 tonnes/ kilotonne feedstock throughput, with a sector average of 1.45 tonnes/ kilotonne feedstock throughput. The highest is again reported in Central Europe, while the lowest is in France. It is important to note that because the survey is a snapshot in time, waste totals for certain country groups may be dominated by large one-off projects. This is especially the case for wastes associated with construction, demolition and remediation.
The top 3 reported hazardous wastes types are sludges (comprising tank bottoms, physical/chemical treatment, biological treatment and other), followed by spent chemicals/acids/bases and then contaminated soil/stones/aggregate/concrete (with approximately one third of these arising from remediation activities). Sludges constitutes 45% of the total hazardous waste reported, while spent chemicals/acids/bases and contaminated soil/stones/aggregate/concrete constitutes 14% and 12%, respectively.
The top 3 non-hazardous wastes comprise soils/stones/aggregate/concrete, followed by metal and biological wastewater treatment sludges. Soils/stones/aggregate/concrete constitutes 65% of the total non-hazardous waste reported, while metal and biological wastewater treatment sludges constitutes 9% and 4%, respectively. The effort made by refineries to control emissions to land and water is evident in the fact that sludges from wastewater treatment and oil-impacted soil/stone/aggregate/concrete wastes together account for 53% of total reported hazardous waste.

An in-depth comparison of the 2013 survey and previous survey data is not possible due to changes in the reporting metrics used. For example, hazardous and non-hazardous wastes were not separately classified in the 1986 and 1993 surveys. However, a few observations can be made, such as that landfill use has reduced significantly, from 40% of total waste in 1993 to 20% in 2013. In parallel, the percentage of waste recycled has increased from 21% to 34% over the same period, showing the progress made by the refining sector over the past 20 years The percentage of waste used for energy recovery has reduced from 15% in 1993 to 7% in 2013, while the percentage of waste disposed of by incineration has reduced slightly from 8% to 6%. It should be noted that these figures may be distorted if wastes sent for treatment are ultimately disposed of by another route, such as energy recovery.
10.3. WASTE MANAGEMENT
The main management option for hazardous waste is treatment (24%), with the remaining tonnage split fairly evenly across the other management options. For non-hazardous waste, recycling is the dominant management option (49%), followed by landfill (29%). The single largest waste tonnage sent for landfill disposal, which could potentially move up the waste hierarchy, is non-hazardous soils/stones/ aggregate/concrete.
10.4. EWC CODES AND HAZARDOUS CODES
The top 10 EWC codes represent approximately 75% of the total hazardous or non-hazardous waste, and therefore represent the majority of the waste classifications used in the industry.
Significant transfer between EU member states was only reported for 3 three hazardous waste types: sulphuric & sulphurous acid; aqueous liquid wastes and spent catalyst. For these waste streams, it is likely that the specialist infrastructure required its waste management is not present in all EU Member States.
10.5. WASTE MANAGEMENT COSTS
The median cost of all hazardous waste management (316 $/tonne) is similar to the median country group cost for Baltic, Benelux and France. In Central Europe and Iberia the median cost is lower, at 63 $/tonne and 85 $/tonne, respectively, whereas in Germany, Mediterranean and UK & Ireland the median cost is closer to 500 $/tonne.
The median cost of all non-hazardous waste management (83 $/tonne) is similar to the median country group cost for Baltic, Central Europe and Iberia. In Benelux and Germany the median cost is lower at 20 $/tonne, whereas in France, Mediterranean and UK & Ireland the median cost is closer to 200 $/tonne.
10.6. COMPARISON OF REPORTED WASTE TONNAGE AND MANAGEMENT COSTS IN 1986, 1993 AND 2013 SURVEYS
A high level comparison of waste tonnage indicates an increase in total and, in particular, relative waste production from 1993 to 2013 despite the number of reporting refineries decreasing from 89 to 74. The increase may be associated with a higher tonnage of material being classified as waste under current EU legislation (e.g. E-PRTR (Regulation EC No. 166/2006) and the Waste Framework Directive (2008/98/EC)).

11. OPPORTUNITIES FOR IMPROVEMENT IN FUTURE WASTE SURVEYS
In general, any future surveys would benefit from reduced use of categories that are ambiguous with regard to the final management option of wastes e.g. “multiple/other” and “treatment”. The challenge, however, in addressing this is that refineries would have to retrieve this data from their waste management contractors, which would add to the complexity of the exercise.
The category referring to chemical waste needs to be more clearly defined and explained in the next survey questionnaire, because different survey respondents interpreted it differently.
Information on activities included in the reported costs was only provided by 32% of survey respondents, and respondents provided a written description of which costs were included. This varied greatly from one site to another and so a statistical analysis of cost vs. waste management options was not feasible. In future surveys this could be addressed by providing a checklist of activities included the total cost (e.g. tank cleaning, taxation, etc.) to increase the response rate and align the cost metrics.
As mentioned above, the collection of more detailed information on waste management is difficult because this data is often held by waste management contractors. In future this could be addressed by reducing the scope of surveys to address specific areas of interest (e.g. how the definition of “treatment” varies between member states), with the current report being used as a reference point.
