CDE has commissioned a waste recycling plant in Salford, Manchester, for NRE Aggregates, part of regeneration business Peel L&P.
NRE Aggregates operates the construction and demolition (C&D) waste plant to produce recycled construction products, with the aim of recycling 240,000 tonnes of waste each year.
The entirely new venture for the business is designed to reaffirm its commitments to the circular economy, reducing its carbon footprint and diverting more waste from landfill.
John Peaker, associate director, asset & materials management, Peel L&P, said, “We strive to use the most innovative methods and techniques to provide quality recycled products. Working with industry experts CDE means partnering with the next generation of innovative thinkers, and we aim to continually improve and refine our methods to reduce carbon emissions and protect the future.”
The plant has been designed to meet NRE Aggregates’ business needs, as well as the site conditions. The 120tph solution incorporates the R4500 primary feeding system, the AggMax scrubbing and classification system, EvoWash sand wash plant, AquaCycle high-rate thickener and filter press sludge dewatering system.
CDE said the R4500 electric scalper with apron feeder delivers ‘unrivalled’ protection of the downstream process by maximising product yield from feed material. The construction of the VibroCentric drive removes unnecessary weight while delivering acceleration up to 5G for ‘enhanced’ screening performance.
The AggMax scrubbing and classification system combines pre-screening, scrubbing, organics removal, sizing, stockpiling, fines recovery and filtrates removal on a compact chassis. CDE added that the integrated trash screen allows for the effective removal of organics and other lightweight contaminants.
The EvoWash sand washing system is engineered for in-spec sands with hydro-cyclone technology and gives ‘unparalleled’ control of silk cut points to produce ‘quality’ materials. It is equipped with the VibroSync drive centre which distributes power evenly across the full screening area.
The AquaCycle high-rate thickener recycles up to 90% of the process water for immediate re-use in the system. It is a single unit described as a ‘highly efficient’ water management solution. Paired with the AquaStore, which receives recycled water from the AquaCycle, ensures all water is reused all the time. CDE’s filter press technology is also designed to eliminate waste and increase water recycling.
Since commissioning, the plant has recycled over 100,000 tonnes of construction, demolition and excavation waste, and is on target to process 240,000 tonnes in its first year of operation.
The firm is now producing four aggregates: 6-10mm, 10-20mm, 20-40mm and 40-80mm, as well as a 0-2mm sand and 0-4mm grit.
“We believe that yesterday’s waste can be a resource of the future,” Mr Peaker added. “We’re recovering valuable resources from historic sites within Greater Manchester and remediating these sites to provide regeneration opportunities. We’re striving towards our own goal of zero-to-landfill, and technology like CDE’s is enabling us to take massive strides in achieving it.”
Mike Bibby, business development manager for CDE, added, “We’ve been working with NRE Aggregates for about five years now and our relationship has gone from strength to strength. We’ve got similar values and goals for local markets, and we were able to have a clear understanding on the business requirements.
“Plants like this are the future of the industry in their ability to minimise waste and maximise value. We are delighted to have played such an important role in the firm’s journey into wet processing and look forward to seeing the partnership develop.”
