Quickly burning plastics at very high temperatures breaks down many toxic components, such as dioxins and furans. This approach is widely used in 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.
A recent study found brominated dioxins as unintentional contaminants in toys made from recycled plastic electronic waste that contained brominated flame retardants. Brominated dioxins have been found to exhibit toxicity similar to that of chlorinated dioxins. They can have negative developmental effects and negative effects on the nervous Organisation and interfere with mechanisms of the endocrine Organisation.[2]
Plasticity also has a technical definition hinein materials science outside the scope of this article referring to the non-reversible change hinein form of solid substances.
In feedstock recycling, waste plastic is converted into its starting chemicals, which can then become fresh plastic. This involves higher energy and capital costs. Alternatively, plastic can Beryllium burned hinein place of fossil fuels hinein energy recovery facilities, or biochemically converted into other useful chemicals for industry.
In 2023, plasticosis, a new disease caused solely by plastics, welches discovered hinein seabirds. The birds identified as having the disease have scarred digestive tracts from ingesting plastic waste.
Also much of the energy used in plastic production is not sustainable energy, for example high temperature from burning fossil gas. However plastics can Schwellenwert some methane emissions, for example packaging to reduce food waste.[127]

Historically, Europe and North America have dominated global plastics production. However, since 2010 Asia has emerged as a significant producer, with China accounting for 31% of total plastic resin production hinein 2020.[29] Regional differences rein the volume of plastics production are driven by Endbenutzer demand, the price of fossil fuel feedstocks, and investments made rein the petrochemical industry.
Plastics are produced in chemical plants by the polymerization of their starting materials (monomers); which are almost always petrochemical hinein nature. Such facilities are normally large and are visually similar to oil refineries, with sprawling pipework running throughout. The large size of these plants allows them to exploit economies of scale.

It has been advocated since the early 1970s,[118] but due to economic and technical challenges, did not impact the management of plastic waste to any significant extent until the late 1980s. The plastics industry has been criticised for lobbying for expansion of recycling programmes, even while research showed that most plastic could not be economically recycled.
Very common. All examples form a coating between the plastic and machine parts during production. Reduces pressure and power usage in the extruder. Reduces imperfections.

Plastics can Beryllium brittle, adding some plasticizer makes them more durable, adding lots makes them flexible
High density polythene (HDPE) is used for making sturdy containers; transparent containers may Beryllium made of PET.
