New CDE plant on show at Dix Pit

Sheehan hold site open days to showcase new CDE construction and demolition waste recycling plant

OXFORD-based public works and civil engineering contractors Sheehan Haulage & Plant Hire, in conjunction with CDE Global, have been holding a series of open days this week to showcase their newly commissioned construction and demolition waste recycling plant.

The new multi-million pound facility, which was more than five years in the planning, was manufactured, installed and commissioned in June 2012 by CDE Global at Sheehan’s 150ha ‘Dix Pit’ recycling site on the outskirts of Stanton Harcourt, in Oxfordshire.

As a result of the investment, 100,000 tonnes per year of construction and demolition waste from Oxford and the surrounding areas will be diverted from landfill and turned into high-value construction aggregates, recycled sands and subsoil.

The facility will be used to process construction, demolition and excavation waste from Sheehan’s own projects, with additional waste being accepted from as far afield as Greater London. The output will be turned into reusable materials for future construction projects – 50% of which is currently used by Sheehan themselves.

The new CDE Global waste recycling plant, which incorporates Aggmax and Evowash units, a Rotomax log-washer, a Prograde triple-deck screen, an Aquacycle thickener and a GHT filter press, is able to process general building rubble and excavation and demolition material into a range of clean aggregates and shingles.

These include 3.3mm, 6mm, 10mm and 40mm grades that are largely used for pipe bedding, with general building sand, Type 1 granular sub-base, fine grade soil and vibro-piling material also being produced.

The plant has the facility to remove deleterious materials, including wood, plastics and metals, which are sent for further recycling, while extracted water is recycled and reused as part of the washing process.

Tara Sheehan, financial director of Sheehan Haulage & Plant Hire, said the company was striving to be a better environmental steward and endeavouring to sustain natural resources wherever possible.

‘By processing all of our own construction and demolition waste as well as increasing volumes of local third party waste, we are already able to produce and supply recycled sand and sustainable aggregates to many local companies, in addition to meeting much of our own requirement for construction materials in the region,’ she commented.
