The recycling symbol we know today – the chasing arrows symbol – was originally designed in 1970 as a way to inform people that a product was recyclable. Just a few years later, in the 1980s, plastic manufacturers started using a very similar symbol, with a number inside, known as the Resin Identification Code (RIC).

As members of the plastics industry, "reduce, reuse, recycle" is an expression we live by. Most people have a basic understanding of how they can apply the three Rs at home, but along with reducing, reusing and recycling throughout the supply chain, the plastics industry is adding another R to the mix: recover. See how […]

In 2016, the majority of plastic waste (91%) that went to treatment went to ''recycling and other recovery'', with the remainder (9%) going to landfill [ 10 ]. Data obtained from Ref. [ 145] demonstrates that from the waste streams which are not currently recycled, about 16% are incinerated and 84% are landfilled.

Abstract. Plastics are the most essential commodities in the world and are replacing the metals, wood, glass, cements and other materials in some application areas. Plastics are easy handling, resource-saving, non-toxic with esthetically attractive. Oil and gas are the major feedstocks for plastics, besides sugar and corn as renewable feedstocks.
