Derwen Group, located in Neath Abbey, South West Wales, offers a range of recycling and waste management solutions. It is the only one of its kind in south wales, running since 1995, processing C&D and C&I materials.
Following developments in 2012, Derwen needed a new processing facility. The plant was to sort a mixture of predominately C&I with C&D waste. As a result of new waste contracts, the plant was required to be versatile and able to process a large variety of waste types.
Turmec carefully designed & built the custom fit, bespoke plant for Derwen.
The plant was designed in phases with phase 1 was built in 2013 and phase 2 carefully included in the original design so that a future retrofit would be easily carried out.
Phase 1, explored in this case study, consisted of:
Long parts separator;
Fines Clean up line, including a secondary fines screen and air density separator;
Air Density separation to separate the waste into more manageable streams;
And Manual picking stations.
Following the commissioning of the plant, Derwen could easily understand what recyclates were present in their waste and, as a result, the design of phase 2 commenced 12 months later.
This plant allowed Derwen to expand their business and gave several other local waste companies a place to bring their materials, instead of landfilling or travelling long distances to recycle elsewhere.
Turmec introduced a secondary shredder to reduce the 400mm RDF to the desired size of sub 100mm, as well as over band magnets that would recover any remaining ferrous fraction and a screening process to further refine the RDF before its baled and exported.
