mixed fibres MRFs
Mixed fibres MRFs process mixed packaging, papers and card collected from either kerbside schemes or commercial sites. O.Kay offers the full range of fibre recovery systems. We supply everything from single sorting lines to fully automated recycling systems that recover News, mixed paper, packaging and card to UK mills’ standard – and all at the touch of a button on a touch screen panel.
Whether you are looking to build a zero-labour plant or a low-capital single picking line, O.Kay will devise a fibre recovery system to suit your required footprint, budget and operating costs. We will also provide guaranteed recovery, purity and availability rating on all our equipment.
The advantages of O.Kay mixed fibre MRFs
- Our MRFs can handle kerbside-collected fibres and/or fibres from commercial and/or industrial sites over the same system.
- Our optical autosorting technology is so advanced that it can sort fibres positively or negatively by detecting ink-surface coverage, ink colours, fibre colour or pre-scanned images or logos
- The autosorting units use NIR (near infrared) detectors and CYMK (cyan, yellow, magenta and black) colour detectors and cameras to recover News and/or brown board and/or grey board and/or plastic films and/or packaging as pure recovered products. The units will also recover contaminants as a material type allowing automated negative sorting
- One, two or three-way autosort units available for muliple material recovery from one unit.
- Touch screen panels on autosort units allow operators to change materials to be recovered within seconds. This negates problems associated with any variations in incoming materials.
- We also use card (disc) screens remove the OCC (rigid card) automatically
- We also use disc screens to separate newspapers from mixed papers automatically
- All disc screens are adjustable for improved separation rates
- Air separation systems can remove minute glass shards
- The quick and easy separation performed by the autosort units and the disc screens allows very high throughputs over the system
- The paper and card recovered at our MRFs meets UK paper and board mill specifications
- We include points of access for the direct baling of monofraction materials such as card
- We design the MRF to use automated or manual sorting to match capital budget
- Presort stations to remove large non-recyclable items
- All our MRFs are fully guarded and covered to protect operators around the MRF
Best quality recovered product
O.Kay is an expert supplier of design-and-build systems capable of processing all tonnages of fibrous materials. Depending on the throughput, we use a mix of mechanical screens, autosorts, air knives and picking/inspection stations to recover top quality materials for sale to UK mills and reprocessors.

COLOUR CAMERA This high-resolution camera records optical criteria such as shapes, colours, textures and images in real time. |
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 Mixed Fibre 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
