The rest was pre-consumer waste from resin production and manufacturing of plastic products (e.g. materials rejected due to unsuitable colour, hardness, or processing characteristics). [35] A large proportion of post-consumer plastic waste consists of plastic packaging. In the United States plastic packaging has been estimated to make up 5% of MSW.
PVC and plastic production produces PVC dust [59] [60] with mortality confirmed among vinyl and polyvinyl chloride workers after reanalysis of data [61] and coronary artery disease and cancer death among vinyl chloride exposed workers [62] Rubber chemical manufacturing impacting mortality among these workers.

The plastics industry manufactures polymer materials—commonly called plastics—and offers services in plastics important to a range of industries, including packaging, building and construction, electronics, aerospace, manufacturing and transportation. It is part of the chemical industry.
Plastic cutting boards Research published last year in the journal Environmental Science & Technology found that using a plastic cutting board can create up to 7,680 flecks of plastic , which can ...
The stakes are particularly high for the fossil fuel industry. As demand for oil and gas declines in the energy sector, plastics and other petrochemicals have become a crucial market for oil ...
An example is zinc oxide, a common paint pigment, which is extremely toxic to aquatic life. [citation needed] Toxicity or other hazards do not imply an environmental hazard, because elimination by sunlight , water or organisms (biological elimination) neutralizes many reactive or poisonous substances. Persistence towards these elimination ...
[1] [2] These microplastics are made primarily from polyethylene, polypropylene, polystyrene, polyvinyl chloride, and other plastics or synthetic resins. [3] Nurdles are the building block, via plastic extrusion or injection molding, for items for everyday life including plastic water bottles, containers, and bags. [4] An example of nurdles
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.
