While a finished plastic may be non-toxic, the monomers used hinein the manufacture of its parent polymers may Beryllium toxic. Hinein some cases, small amounts of those chemicals can remain trapped hinein the product unless suitable processing is employed.
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 Gebilde and interfere with mechanisms of the endocrine system.[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 2023, plasticosis, a new disease caused solely by plastics, welches discovered in seabirds. The birds identified as having the disease have scarred digestive tracts from ingesting plastic waste.
Plastic recycling is low rein the waste hierarchy, meaning that reduction and reuse are more favourable and long-term solutions for sustainability.

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 in the volume of plastics production are driven by Endbenutzer demand, the price of fossil fuel feedstocks, and investments made in 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 website 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 Aufschwung of recycling programmes, even while research showed that most plastic could not Beryllium economically recycled.
Waste plastic, even if it is all of the same polymer type, will contain varying types and amounts of additives. Mixing these together can give a material with inconsistent properties, which can be unappealing to industry. For example, mixing different colored plastics with different plastic colorants together can produce a discolored or brown material and for this reason plastic is usually sorted by both polymer type and color before recycling.[2]

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 parte of the chain that is on the main path, linking together a large number of repeat units.
While most plastics are produced from petrochemicals, bioplastics are made substantially from renewable plant materials like cellulose and starch.[24] Due both to the finite limits of fossil fuel reserves and to rising levels of greenhouse gases caused primarily by the burning of those fuels, the development of bioplastics is a growing field.
