4.2 QUALITY MANAGEMENT SYSTEM

4.3 RECOGNITION

5. OUR FACILITIES

The CRP is a special purpose facility that is capable of recycling spent catalysts and regenerating used catalysts generated by refineries, petrochemical, oleo chemical, pharmaceutical and chemical companies. The Thermal Oxidation Process System (TOPS) technology adopted at QESB offers substantial cost saving benefits to clients. Furthermore, it eliminates landfilling of the spent catalysts, providing a closed-loop system (wherein we minimize wastage through recycling and recovery) as well as providing a more environmental friendly solution for those scheduled wastes.

The CRP’s approved processing capacity permitted based on the Environment Impact Assessment (EIA) is 6,500 metric tons per year. We are currently operating the CRP at 70% of its annual capacity.

Utilizing the ‘Thermal Oxidation Process System’ (TOPS) enables the elimination of hazardous contaminants from the spent catalysts. The treated catalyst will then be sent to reputable refiners for the PGM recovery in the form of usable metals such as platinum, palladium, rhodium and silver.

Currently, QESB has business and technical partnerships with HERAUES Precious Metal of Germany, Johnson Matthey of United Kingdom and SABIN Metal West Corporation of United States. These refiners are members of the London Platinum and Palladium Market’s (LPPM) Good List and have track records spanning hundreds of years in the PGM refining and trading.

This value added service is part of the screening process for separation of used catalyst with subtle physical differences. DG separates catalyst particles of similar size based on individualparticle density.

QESB currently use the TOPS technology to treat spent catalyst as it is able to minimise physical impact during the process resulting in higher PGM yield. This process eliminates and reduces contaminants without altering the chemical composition of the spent catalyst.

Initially, when the spent catalyst enters the CRP, it shall undergo the screening process. The first stage in screening process is to separate between catalysts and non-catalysts. Then, the spent catalyst shall undergo second stage process, where the spent catalyst is separated based on its physical forms; pellets, dust, sweep and broken catalyst.

5.1.1 SCREENING PROCESS Screening

process at CRP

The FRP processes all types of waste oil into stabilized diesel utilising QESB’s proprietary Robys Technology as well as other by-products such as fuel oil and naphtha. Representative of the latest innovation in waste oil recycling technology, it is a technically superior process in comparison to the traditional method where waste oil only undergoes filtration process to produce burning fuel. To date, there are only two companies in the world that possessed this technology, QESB being one of them.

The FRP has a DOE-approved capacity of 30,000 metric tons per month for recycling oil and 90,000 metric tons per month to process various hydrocarbon effluents. It is designed for a continuous processing up to 300 days a year.

The FRP represents an all-in-one facility for effective liquid waste management designed to turn waste oil, hydrocarbon by-products and petrochemical liquid wastes into higher value-added products.

6. PRODUCTS & SERVICESThere are 2 main types of industrial scheduled wastes namely solids and liquids. The solid scheduled wastes comprise mainly of spent catalyst from the petrochemical and oleo chemical industries. Whereas liquid scheduled waste generally refer to waste oil, Oil Base Mud (OBM), slop and sludge. QESB provides end to end management services for both types of wastes under licensed by DOE.

Catalysts are used in reactors of petrochemical plants and remain effective for up to 15 months, after which degradation occurs and a change-out is required. QESB provides the treatment of the spent catalysts and thereafter are reclassified as non-scheduled wastes. Post-decontamination, they can be safely disposed or recycled and recovered. The latter is mainly for spent catalysts with high metal content.

The recycling of PGM and base metal spent catalyst at the end of its useful life is economically viable and environment-friendly. Precious metal catalysts are crucial for many technical syntheses. Their main application in the downstream sector of oil and gas industry are catalytic reforming, isomerization, hydrocracking and hydrogenation processes. The noble metals involved are mainly platinum (Pt) and palladium (Pd), but also other platinum group metals (PGM) such as ruthenium (Ru), iridium (Ir), rhodium (Rh) as well as silver (Ag), either alone or in combination. Often, other metals such as nickel (Ni), zinc (Zn), cobalt (Co), lead (Pb) and molybdenum (Mo) are used as promoters.

In Malaysia, under the Environmental Quality Act 2005 (Scheduled Wastes), spent catalyst is considered hazardous materials and falls under the SW202 waste code. Thus, all the movement of the spent catalyst is regulated and its handling has to comply with all the regulation as follows:• Environmental Quality (Scheduled Wastes)

Regulations 1989.• Third Schedule (Regulation 10) Labelling

requirement for Scheduled wastes. § Fifth Schedule (Regulation 11) Inventory of Scheduled wastes.

• Sixth Schedule (Regulation 12) Consignment Note for Scheduled wastes.

• Seventh Schedule (Regulation 13) Information.

With our IRRC, QESB envisages itself as a one-stop center for environmental solutions. To that end, we provide integrated scheduled waste management services or ISWMS. These include the following:• Inspection all types of scheduled wastes,

wherein we help identify and advise clients on the proper treatment and/or disposal in accordance with legal requirements.

• Packaging and labelling. This includes the supply of bags, new and reconditioned drums, various types of containers and pallets to ensure compliance with statutes and Malaysian government and international standards.

• Logistics and transportation solutions for scheduled waste.

• HSEcompliance.Our specialty includes knowledge of types of scheduled waste and their proper handling to ensure that global safety standards are adhered to.

6.1 DECONTAMINATION

6.2 SIEVING 6.4 ADSORBENT AND SPENT CATALYST DISPOSAL

6.3 DENSITY GRADINGThis involves:• Waste inventory management.• Decontamination process which involves

the removal of impurities such as carbon and other volatile organic content from spent catalysts using pyrolysis i.e. controlled combustion technology which is also known as TOPS. Thus transforming it into non- scheduled waste.

This screening process is firstly to separate between catalysts and non-catalysts. Then, the spent catalyst shall undergo second stage process, where the spent catalyst is separated based on its physical forms; pellets, dust, sweep and broken catalyst.

This involves inter alia:• Waste inventory management. This

includes planning, implementation and monitoring of waste inventory to ensure compliance.

• Disposal of absorbent and spent catalyst after decontamination process.

This value-added service is part of the screening process for separation of used catalyst with subtle physical differences. Density Grading Process separates catalyst particles of similar size based on individual particle density.
