Recycling Plant with Sophisticated Shredder, Granulator & Dehydrator 2011-12-26
For large household white goods, such as fridges and cookers, recycling infrastructure is strong. However, for smaller more complicated equipment, the development of new infrastructure and technology has become necessary. There are four broad methods employed by industry to recycle:
– the manual separation of reusable and recyclable components – the removal of hazardous components followed by granulating and shredding, in order to remove the recyclable raw materials such as plastic and ferrous metal – metal can be recovered after the more combustible material has been incinerated – precious metals such as gold and silver can be removed from printed circuit boards and components via chemical processes Mechanical Plastic Recycling
Mechanical plastic recycling refers to processes which involve the shredding, granulation, blending, dehydration, cutting, washing and vibratory sieving of waste plastics. When doing plastic recycling, plastics must be sorted prior to mechanical recycling. Most sorting for mechanical plastic recycling is done by trained staff who manually sort the plastics into polymer type and/or color. Technology is being introduced to sort plastics automatically, using various techniques such as X-ray fluorescence, infrared and near infrared spectroscopy, electrostatics and flotation. After sorting, the plastic is either melted down directly and moulded into new shapes, or melted down after being shredded into flakes and then processed into granules called regranulate.
