Collection
At the initial stage of the recycling process, the focus is on gathering recyclables from households, businesses et. It is crucial for everyone to correctly separate their plastics for collection and recycle as much as possible.
Local authorities or waste management contractors handle the collection of these recyclables.
Additional collection points include recycling centers, in-store collection points, and local recycling sites. Effective plastie collection is vital for the recycling system to function efficiently, as it increases the availability of material for reprocessing and creating new products.
Segregation
The second stage is sorting plastic from other materials and this is done at a Material Recovery Facility (MRF). This material may then go onto a Plastic Recovery Facility (PRF) for further sorting into the different types of plastic.
The mixed recycling will initially be removed from the collection vehicles and then mechanically placed onto conveyer belts.
The sorting process begins at a Material Recovery Facility (MRF) to separate plastic from other materials.
After being unloaded from collection vehicles, the mixed recycling is mechanically placed on conveyor belts to ensure a continuous flow through the sorting facility.
Shredding
At a crucial stage in plastic recycling, the process involves shredding or grinding plastic into smaller flakes.
Once the plastic has been washed and sorted, it goes through shredding machines where it is transformed into smaller plastic pieces.
Different shredding methods are employed based on the classification and shredder techniques. For instance, Hammer Mills utilize swiveling hammers in a rotary drum to pulverize plastics, while Shear Shredders employ rotary cutters and guillotines to cut plastics according to industry standards.
Subsequent sorting steps may be carried out to ensure a pure material stream is achieved.
Granulation
The shredded plastic fragments are introduced into a hopper and subsequently transported into an extruder. Within the extruder, the plastic is subjected to heat through heating elements or mechanical friction to reach its melting point. This process transforms the plastic into a viscous state, enabling smooth flow.
Sheet Press
Recycling is a crucial aspect of environmental conservation, and waste plastic recycling is one of the most important steps in this regard. A sheet press machine is a type of equipment that is used in waste plastic recycling. This machine uses a hydraulic press to turn shredded plastic into recycled sheets.
The use of a sheet press machine in waste plastic recycling offers a range of benefits. Firstly, it helps reduce the amount of plastic waste that ends up in landfills, thereby minimizing the environmental impact of plastic waste. Secondly, the use of recycled plastic sheets can help reduce the cost of raw materials used in the production of various products. Additionally, the use of recycled plastic sheets also helps conserve natural resources such as oil, which is used in the production of new plastic products.
