commingled MRFs

Commingled MRFs process recyclables such as papers, card, plastics and cans that are separately collected by the householder in dedicated bags, boxes or wheelie bins. O.Kay MRFs are designed and built to order and range from single picking lines to automated, high-tonnage systems.

Best quality recovered product

O.Kay is an expert supplier of design-and-build systems capable of processing all tonnages of commingled recyclables. Depending on the throughput, we use a mix of mechanical screens, autosorts, air knives, magnets, eddy current separators and picking stations to recover top quality materials for sale to UK mills and reprocessors. For more information on all machines found within a MRF, please use the navigation bar on the left.

Worker safety

Whether we are installing a single sorting line or a high-tonnage automated MRF, we take the safety of our workers – and the safety your staff – very seriously. Our engineers are trained to the latest UK H&S standards and they infuse these standards into all our designs. They also arrange the in-depth training of all your operating staff so they too will work safely to the highest standards.

Typical equipment within a Commingled MRF
Air Knives – to suck/blow out the lights fraction from any stream
Bag Openers – to open bags/sacks and release recyclables
Balers – to reduce the recovered product in size for reduced transport costs
Ballistic Separators – to separate flat-and-light items from rolling-and-heavy items
Bottle Perforators (Plastics) – to pierce and flatten plastic bottles for increased storage and reduced transport costs
Bottle Perforators (Glass) – to smash glass bottles for improved downstream sorting
Cabins – to protect sorters (shelter, heating, ventilation and air conditioning)
Can Crushers – to reduce the size/volume of recovered cans in storage bunker/transport
Conveyors – to transfer material to the screens, separators and bunkers
De-stoners – to separate heavy materials from light materials Disc (Card) Screens – to remove the fines fraction, to sort papers and card
Eddy Current Separators – to remove the non-ferrous content
Electro and Overband Magnets – to remove the ferrous content
Metering Systems – to allow front-end storage and a ‘perfect-flow’ feed into MRF
Paper Autosorts – to automatically separate all packaging, grey board and brown board from the News fraction using NIR (near infrared) detectors and CYNK (cyan, yellow, magenta and black) detectors and cameras
Plastic Autosorts – to automatically remove all plastics by polymer type and/or by colour
Pre-sorts – a type of picking belt used ahead of the primary screen to remove large contaminants
Picking Belts – to allow human sorters to sort materials or inspect recovered materials
SCADA Control Systems - to monitor and control large plants remotely
Trommels – to separate all types of materials by size (two, three or four-way splits available within single drum)
Walking Floors – to allow fast dumping of materials from trucks onto walking floor, which feeds materials into system. Also used in bunkers to walk materials onto baler feed conveyor
