Introduction to Plastic Recycling and Plastic Recycling Line

Plastic recycling came to fruition during the environmental revolution of the late 1960s. The idea to recycle products is as old as mankind when the first mother gave the younger child the worn clothes of his sibling. During World War II, the U.S. government asked the citizenry to recycle and reuse products like tires, steel, and even nylon, but it wasn’t until the groovy era and culture of the 1960’s, that people’s minds turned toward counter-cultural ideas including salvaging the ever-increasing numbers of plastic containers foisted on the American consumer.
The first plastic recycling mill for Waste Techniques was built in Conshohocken, Pennsylvania, and began working in 1972. It took several years and a concerted effort for the average Joe to embrace the recycling habit, but embrace he did and continues to do so in increasing numbers. Plastic recycling is unlike glass or metal processes due to the greater number of steps involved and the use of dyes, fillers and other additives used in “virgin” plastics.

The plastic recycling line process begins with sorting the various items by their resin content. The recycling mill sorts the used plastics by the symbols and may perform an additional sort based on the color of the plastic.
Once sorted, the plastics are chopped up into small pieces and chunks.These pieces are then cleaned to further remove debris like paper labels, residue from what was inside the plastic, dirt, dust, and other small contaminants.
Once cleaned, the plastic pieces are melted down and compressed into tiny pellets called nurdles. Once in this state, the recycled plastic pellets are now ready to reuse and fashion into new and completely different products, as recycled plastic is hardly ever used to create the same or identical plastic item of its former self.
