Plastics Recycling - Technology and Equipment
The continuously increasing cost of fresh (virgin) plastic resin has made plastic recycling both desirable and attractive.
Processes that use virgin material are well defined and well controllable.
For example, a manufacturer of Raffia tape or PE film can precisely predict his daily and monthly output subject to availability of raw materials and no unplanned shutdowns.
However, the recycling industry does not usually have this luxury.
The (recycling) processor is dependent on scrap and waste plastic collection; hence there is a great variation in quality and availability of inputs.
There is a common misconception, especially among extruder manufacturers, that recycling equals granulation. In fact, granulation (palletizing) is the last step in the recycling process; it is relatively easy and the output is directly determined by the input of material.
The recycling process has 5 different stages:
- Scrap sorting
- Shredding or crushing
Depending on the nature of scrap and the nature of application, some of these processes may be redundant. For example, clean material such as factory waste may not require washing/drying. Sometimes, material used for injection molding may be supplied in the crushed form without granulation.
- PE film
- Raffia Bags/ Tape
- HDPE Blow Molded Containers
- PP Injection Molding
- PP film
- PET bottles
- Most processors stick to one or two of the above.
Advantage: We also undertake turnkey supply of complete extrusion projects. We have exports to over 10 countries.
Hence we look at Plastics Recycling from both sides; as a machinery manufacturer as well as a processor. This means the equipment recommended by us is tested in actual working conditions.
Throughput: Recycling Plants can be designed for outputs ranging from 50 kg/hr to 500 kg/hr.
Batch Process / Continuous Process In general, material can be processed either in
Batch process - (say a batch of 50 kg to may be processed in 20 minutes in a washing machine.) or by
Continuous process - (where the material moves from one process to the next - and output is measured in kg/hr) In general, batch process plants have 3 characteristics vis-à-vis continuous process plants:
- Feeding and removal of material from each equipment is manual. The movement of material from one process to the next is also manual.
- Power requirements are low.
- The process is flexible. Equipment can be added or removed to accommodate change in the input.
Continuous Process Plants are usually preferred when
- Higher outputs are required
- When type of input is fixed.
- Labor is expensive /and/ or scarce.
