“Please recycle” is a common phrase in almost all labels of plastic and paper products in the market. Manufacturers of plastic and paper strongly encourage consumers to get involved in paper recycling, as well as plastic recycling. But for one to recycle plastics, one has a lot to understand first. You see, there is a certain process to follow in waste recycling especially plastic products.
Plastics are one of the most difficult to recycle and before the recycling process can begin, all plastic materials have to be sorted first according to the Resin Identification Code. This will serve a guide for recyclers.
There are almost 50 different main groups of plastics, each containing many different varieties. The Resin Identification Code system was introduced to make the sorting of recyclable products easier and more universal.
This is the Resin Identification Code used for plastic materials.

Sorting plastics is expensive and time-consuming but this is essential in the recycling process. Despite the challenges, more and more plastics are being recycled every year. The amount of plastics that are recycled has increased since 1990. According to American Plastics Council, almost 1,800 U.S. businesses reclaim post-consumer plastics. Still, with this number, the United States only recycled about five percent of the plastics produced domestically.
Plastics are first collected from curbside recycling bins and drop-off locations. From there, they go to a material recovery facility where they are sorted and sent to a reclamation facility. At the reclamation facility, the plastic is inspected and washed. Next it is chopped into small flakes. The flakes are then placed in a flotation tank and then dried in a tumbler. The dried flakes are then placed in a costly extruder where they are melted. The melted plastic is sifted through a screen to remove any contaminants and then it is formed into strands. Finally, the strands are chopped into pellets and sold to manufacturers to make new products. This starts a new life for the recycled plastics. As technology continues to evolve, the cost of the recycling plastic process gradually decreases and hopefully, the amount of recycled plastics will increase. At the same time, consumers have become more aware of the effect of plastic wastes on the planet so they are reducing the use of plastic bottles and bags before it is too late.
We ourselves do our share at home. Why not start separating your plastic items from other waste materials so that at least you have done a little help in saving our planet? It’s not a big task but entails discipline.
