The recycling company Wastecycle in Nottingham expects to process in excess of 45,000t / year and are pleased that the implementation of the plant has allowed them the flexibly to achieve positive results from the various waste streams.

The management of Wastecycle asked KMH Systems and REDWAVE to assist them in developing together a new plant based on the following objectives:

  • Increase through-put of the entire plant
  • Reduce labour cost
  • Incorporate increase level of automation and sorting
  • Achieve better separation of the intake materials to help add more value to the separated products
  • Have the equipment flexible to handle other waste streams generated from, household dry co-mingled waste primarily, also C&I waste and skip waste which has had primary sorting in other plant on the site
  • Glass will now be part of the Dry Waste intake
  • Where possible use the existing equipment on site
  • Detailed consideration to be given about a short as possible installation / commissioning window

The following equipment was installed to achieve the best results for Wastecycle:

A walking floor dosing drum / bunker was selected to allow the client to have controlled even flow of 12t / hr into the plant.

Due to the variable nature of the feed stock ranging from dry-comingled to C&I it was important to have space for pre-pickers to remove large cardboard, film and other non- conforming items.

After the pre-picking the materials are delivered to an Ballistic screen where the materials are divided into 2 Dimension materials (such as paper card and film) 3 Dimensional materials (such as cans, plastic bottles, glass etc.) and fines.

The 2 Dimensional materials are delivered into a REDWAVE 2400 mm NIR 2 way sorting unit which positively ejects contamination leaving a News and Pams product which then is delivered to the baler after passing through a manual quality control station.

The 3 Dimensional materials passes over a glass breaking screen and then through ferrous and non-ferrous separation and the remaining plastic bottles are sorted with a REDWAVE 1600 mm NIR 3 –way . The flexibility of the 3 way REDWAVE will allow the client to positively remove 2 different products for example HDPE and PET.

These products and the defaulting materials pass through manual quality control and then into storage bunkers ready for baling.

The control system allows the client to have a flexibility to change speeds based on different product and the REDWAVEs can be monitored remotely to allow re-calibration should the client wish to change their sorting requirements.

The fines are conveyed to the clients existing trommel with an air system allowing the glass to be cleaned by removing small paper and plastics.

Quality separation and increase through-put and flexibility puts the Wastecyle in a good market position in the competitive world of recycling.
