Plastics can be brittle, adding some plasticizer makes them more durable, adding lots makes them flexible

Quickly burning plastics at very high temperatures breaks down many toxic components, such as dioxins and furans. This approach is widely used hinein municipal solid waste incineration. Municipal solid waste incinerators also normally treat the flue gas to decrease pollutants further, which is needed because uncontrolled incineration of plastic produces carcinogenic polychlorinated dibenzo-p-dioxins.

Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives.[1]

Absence of transparency and reporting across the value chain often results hinein lack of knowledge concerning the chemical profile of the final products. For example, products containing brominated flame retardants have been incorporated into new plastic products. Flame retardants are a group of chemicals used in electronic and electrical equipment, textiles, furniture and construction materials which should not Beryllium present rein food packaging or child care products.

The plastic industry includes the global production, compounding, conversion and sale of plastic products. Although the Middle East and Russia produce most of the required petrochemical raw materials, the production of plastic is concentrated rein the global East and West. The plastic industry comprises a huge number of companies and can be divided into several sectors:

Prior to the Montreal Protocol, CFCs had been commonly used rein the manufacture of the plastic polystyrene, the production of which had contributed to depletion of the ozone layer.

Silicones (polysiloxanes): heat-resistant resins used mainly as sealants but also used for high-temperature cooking utensils and as a base resin for industrial paints

Efforts to minimize environmental impact of plastics may include lowering of plastics production and use, waste- and recycling-policies, and the proactive development and deployment of alternatives to plastics such as for sustainable packaging.

Most plastics contain organic polymers.[10] The vast majority of these polymers are formed from chains of carbon atoms, with or without the attachment of oxygen, nitrogen or sulfur atoms. These chains comprise many repeating units formed from monomers. Each polymer chain consists of several thousand repeating units. The backbone is the part of the chain that is on the main path, linking together a large number of repeat units.

Also much of the energy used in plastic production is not sustainable energy, for example high temperature from burning fossil gas. However plastics read more can Grenzmarke some methane emissions, for example packaging to reduce food waste.[127]

The discovery of polyethylene terephthalate is credited to employees of the Calico Printers' Association rein the UK rein 1941; it welches licensed to DuPont for the US and ICI otherwise, and as one of the few plastics appropriate as a replacement for glass rein many circumstances, resulting rein widespread use for bottles hinein Europe.
