The plant, the first Terex Recycling Systems installation, was specifically tailored to suit Collard Group's site and the material that would be fed into it. The team worked within restricted space and constraints of fitting the plant inside and around the existing building, all whilst planning the installation around Collard Group's site works, which included the erection of a new building. Together with its distributor Molson Green, Terex Recycling Systems developed a process incorporating advanced mechanical separation that would increase Collard Group's processing capacity and recover products of a higher purity than previously achieved.
Thomas McKiver, sales director, Molson Green, said: "We are delighted to have sold and installed Terex Recycling Systems' first plant to the Collard Group. This plant will help them achieve their desired targets of increasing processing capacity and to recover greater percentages of cleaner recycling products, thus diverting more material from landfill."
The process starts with skip material being loaded into a Waste Feeder and conveyed to a Combi Screen, which separates into four size fractions using a combination of 3D and Flip-Flow screening (0-10mm, 10-50mm, 50-100mm and +100mm). Over-Band Magnets recover ferrous metals from 0-10mm, 10-50mm and 50-100mm, and Air Separators remove light material from 10-50mm and 50-100mm. A Manual Quality Control Picking Station has operators working to remove any remaining contaminants from the 10-100mm heavy fraction. An Eddy Current Separator recovers non-ferrous metal from the 10-100mm heavy fraction. Another Manual Picking Station has operators recovering materials such as wood, card, and plastic from the +100mm, and an Over-Band Magnet recovers ferrous metal. Finally, an Air Separator removes light material from the +100mm.
The outcome is a highly efficient plant that is processing skip waste—a mixture of Commercial and Industrial (C&I) and Construction and Demolition (C&D) waste—to produce 0-10mm fines, ferrous metals, clean 10-100mm heavy fraction (inert), non-ferrous metals, wood, plastic, paper & card, and clean +100m heavy fraction (inert) materials.
Robert Collard, managing director of Collard Group, said: "We at the Collard Group are driven by a zero waste to landfill commitment; we take waste from the site and process it to make it useful again. We call this recycling the past for the future. To achieve this goal, it is important that we have the latest equipment that is optimised to meet our specifications.
"Terex Recycling Systems and Molson Green worked with us to ensure the design, delivery and installation of our new plant worked around our site operations, also taking into consideration our site preparation works to include foundations building modifications whilst also keeping the plant footprint to a minimum to aid their site operations."
