Waste

Organic Waste Treatment & RecyclingOur Team

MWH and HTP have formed a

collaborative team to deliver waste

management projects within the

UK. The two parties bring together

extensive experience in the areas of:

• Waste analysis and design of

innovative agricultural recycling

or treatment solutions.

• Materials recycling and sorting.

• Design, build and commissioning

of Mechanical Biological Treatment,

Anaerobic Digestion and In-vessel

Composting Facilities.

• Biogas management.

• Agricultural Recycling, digestate

disposal and downstream treatment.

The MWH and HTP team are able to

design and deliver the most appropriate

solution for treatment or recycling of

municipal, organic, food processing

and industrial wastes. The team can

provide a full range of design, build and

commissioning services including:

• Feasibility - input waste identification,

characterisation and project

technology selection or agricultural

recycling solution.

• Design - conceptual development

through to detail, conventional or

within a Design and Build (D&B) model.

• Client Technical Advisor (TA).

• Engineering Procurement

Construction Contracting (EPC),

including commissioning.

• Trouble shooting of existing treatment

plants - process re-engineering or

refurbishment to treat new wastes.

• Waste management – agricultural

recycling services of waste to

land, identifying benefits from

organic wastes and industrial by-

products, under waste management

regulations, turning cost into revenue.

Partnership

MWH is a global engineering

consultant and contractor in the water,

waste, energy and environmental

sectors and has designed and

delivered, in partnership, hundreds

of waste management facilities and

recycling solutions across the globe.

These range from sewage treatment

sludge and bio-residuals over

domestic solid waste to hazardous

industrial waste and medical waste.

References include controlled

landfills, materials sorting, recycling

and in-vessel composting facilities,

mechanical biological treatment

plant, mass burn Energy from Waste

plants as well as gasification plants

and biomass power plants. MWH has

designed more than twenty anaerobic

digestion plants for sludge and organic

waste, often in combination with

cogeneration, waste management and

digestate treatment and disposal.

HTP is one of the leading engineering

consultants in Germany for waste sorting

and recycling. Founded in the early

1990’s, it has designed over 50 reference

plants in Germany and Northern Europe,

treating a wide variety of waste such

as food waste, various organic waste

streams and municipal solid waste.

HTP has worked with all leading

European mechanical equipment

and process suppliers and thus

has a clear understanding of the

capabilities of each supplier and their

equipment. HTP is independent and

so is able to design cost effective,

innovative and sustainable waste

processing solutions, independent

from specific suppliers.

Biogas Management

The commercial viability of any organic waste AD or MBT project is strongly

dependent upon maximising the revenue from the AD biogas. Three main

options are developing in the UK biomass AD market:

• On-site cogeneration.

• Biogas cleaning and injection into the national gas grid.

• Biogas conditioning for commercial fuel applications.

MWH has been involved in the design and installation of many cogeneration

facilities. MWH is working with United Utilities and WRAP on the biogas to bio-

methane demonstration project at Davyhulme wastewater treatment works.

Materials Sorting and Mechanical Pre-treatment

MWH-HTP can offer independent

experience on Materials Recycling

Facilities (MRF), Sorting Facilities

and Mechanical Pretreatment

processes. MWH-HTP’s extensive

experience allows expert project

feasibility assessment.

MWH-HTP works closely with the

client to characterise the waste.

Waste characterisation enables

MWH-HTP to design, specify

and deliver the most appropriate

flow sheet for the client, and also

provide flexibility to treat the full

range of proposed waste streams.

By combining their capabilities, MWH and HTP can offer the most comprehensive expertise and services currently available on the UK waste market. It brings decades of European and Global expertise to the UK through MWH’s UK network of 20 offices with over 1500 employees.

Mechanical Biological Treatment, Anaerobic Digestion and In-Vessel Composting

MWH has designed a number

of different anaerobic digestion

processes, specific to project

requirements, and have included a

number of AD variants, undertaking

conceptual, detail design and

contractor review roles. The type of

anaerobic digestion processes have

been designed specific to project

requirements and have covered a

number of AD variants: single stage,

two phase, temperature phase and

thermal hydrolysis.

Organic AD - MWH has provided

technical support on anaerobic

digestion facilities for municipal, food

and other organic waste streams.

Enzymic two phase hydrolysis –

MWH was engaged to provide an

enhanced digestion upgrade to

Blackburn AD treatment centre, to

produce a fully pasteurised digestate

product. Blackburn was the first

Enhanced Enzymic Hydrolysis

process installed in the UK.

Thermal hydrolysis – MWH was

engaged to provide an enhanced

digestion upgrade to Northumbrian

Water’s Bran Sands AD centre.

Bran Sands has just come on

stream and at present is the

largest site utilising Cambi thermal

hydrolysis technology.

MWH is a UK leader in developing cost

effective, innovative and sustainable

recycling operations, ensuring Duty

of Care compliance, delivering value

to our clients through improved

waste management practices and

performance.

Diversion of waste from landfill and

reduction in carbon footprint are

achieved through our solutions and

we manage circa 140,000 tonnes

per annum of waste and digestate

recycling. We tailor nutrients supplied

by waste and digestate to crop

requirements and soil fertility levels by

analysis. Our intelligent and pragmatic

approaches recover a wide range of

organic waste streams including:

• De-inked paper pulp.

• Wastes from the preparation of

meat, fish and other productions

of animal origin, including Cat 3

catering wastes.

• Waste from fruit, vegetable and

cereal manufacture.

• Waste from the dairy

product industry.

• Waste from the manufacture of lime.

• Wastes from aerobic and

anaerobic treatment.

• Sludges from water clarification.

Our services identify beneficial

properties of industrial by-products by

assessment satisfying requirements

of Waste Management Licensing

Regulations 2005. MWH ByProduct

Recovery provides new and innovative

outlets for wastes including brick and

block manufacture, using waste to

treat waste, assessing waste suitability

for co-incineration within the cement

industry and the marketing of waste as

‘products’. Our clients include Cemex,

Heinz, Nestle and Northern Foods. Our

‘one stop shop’ service includes:

• Waste collection and transportation.

• Identification of appropriate land

banks, soil sampling and analysis.

• Pollution risk assessments.

• Registration of appropriate

waste exemption with

Environment Agency.

• Tailoring crop nutrient requirements

by application rate and soil fertility.

• Provision of spreading equipment

tankers, umbilical units, shallow

injectors, irrigators, rear and side

discharge spreaders.

• Post application checks for

demonstration of agricultural benefit.
