How the Process Works
From the feeder and trommel, the waste material is split into a 0 - 40mm fraction and an oversize fraction. The smaller fraction passes under a magnet, to remove any ferrous metal and then into a Spaleck Flip-Flow screen and a DS150 density separator. Working together, these two machines process this waste stream to produce a clean -10mm material,
a 10mm - 40mm heavy fraction which can be used in the production of recycled aggregates (thereby helping to meet targets to divert material from landfill) and a light residual waste which becomes an element in an RDF type material. This part of the process is known as “fines clean up”, and it was added to the system to meet the 10% LOI (Loss on Ignition test).
The oversize fraction passes into a bespoke picking cabin, where operatives manually segregate products such as wood, plastic, paper to be recycled. The remaining fraction then passes out of the picking cabin and under another ferrous metal magnet and through a blower, to remove any residual light material. The result of this process is the creation of a clean heavy material which can be further reprocessed if required, into a recycled construction material.
Green Planet’s Commitment to Recycling
As well as the new Kiverco recycling plant, Green Planet has invested over £420k in newer vehicles with better MPG and lower emissions and by February 2019, they will have invested a further £1.3m in equipment and trucks.
Director, Keven Nixon says, “Our company has always promoted the virtues of responsible recycling as a means of achieving a whole host of objectives, from keeping space in landfills to helping the environment. Our recent investments demonstrate how seriously we take our responsibilities. Now with our new recycling system, we can now recycle waste materials in higher volumes than ever before and meet even higher environmental targets. We have been really impressed with Kiverco’s consultation process and how they designed elements of our plant to accommodate some of our requests. The installation was completed within three weeks and we were more than delighted with the end result.” July 2018 - Issue 51
