Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
Resin code for polyethylene terephthalate Polypropylene lid of a Tic Tac box, with a living hinge and the resin identification code, 5, under its flap. The Resin Identification Code (RIC) is a technical standard with a set of symbols appearing on plastic products that identify the plastic resin out of which the product is made. [1]
Plastic recycling is the processing of plastic waste into other products. [1] [2] [3] Recycling can reduce dependence on landfill, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. [4] [5] [6] Recycling rates lag behind those of other recoverable materials, such as aluminium, glass and paper.
The other five types of plastic include #3 PVC, or Polyvinyl Chloride, #4 LDPE, or Low-Density Polyethylene, #5 PP, or Polypropylene, #6 PS, or Polystyrene, and the final one is #7, a blend of ...

Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling. [1]
During that time, 30 or 20% of those with plastics had a heart attack, stroke or died from any cause, compared to eight or about 8% of those with no evidence of plastics.
By reducing the production and use of raw materials, closed-loop recycling minimizes harm to the environment and discourages resource depletion. [5] In contrast, open-loop recycling is the process by which a product is recycled but has to be mixed with raw materials to become a new product, typically leading to downcycling .
