In traditional mechanical recycling, facilities sort through consumers' recyclables collected by local trash haulers, separating plastics from metal, glass and other materials. To ease this tedious process, AMP Robotics has developed a machine learning-based technology that identifies different types of plastics and pulls unwanted materials off the line with a pneumatic arm. Next, the separated plastics are shredded, washed, melted and repelletized. Then, plastics destined for food packaging undergo additional finishing steps. Although recycling firms have developed new technologies, such as solvent extraction, to recycle different types of plastic more efficiently, consumer product companies must redesign their packaging, for example, by removing multiple plastics and metalized layers, to make them easier to recycle. Also, experts say that consumers need to do their part by putting more of their used plastics into the recycling bin.
