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.
