iQRenew and its partners Materials Recycling Facilities (MRF’s) receive co-mingled materials and cardboard.
By investing in these MRF’s, iQRenew will enhance their capability to secondary sort and prepare waste streams for markets.
What goes on at a MRF?
Sorting Steps at a Material Recovery Facility (MRF)
1. Pre-Sort:
MRF staff manually remove contamination (e.g. plastic bags)
2. Star Screen Sorting:
A series of shafts fitted with rotating star shaped discs propel paper and cardboard forward, while bottles, cans and containers fall backward.
3. Glass:
Sent for further sorting by colour or to glass crusher.
4. Magnets:
Rotating magnets pick up steel cans.
5. Eddy Currents:
An electromagnetic field repels aluminium cans away from other products.
6. Optical Sorting:
Infrared sensors and air jets sort plastic types 1 and 2 (PET and HDPE respectively).
7. Manual Sorting:
MRF staff manually sort the other plastic types (3 to 7).
