A literature study made hinein 2022 by geologist student Björn Lycke shows that the amount of microplastics hinein sediment is increasing worldwide, especially in ports and tourist beaches.[82]

Hazardous molds have been found aboard space stations that degrade rubber into a digestible form.[97]

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 rein 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 rein electronic and electrical equipment, textiles, furniture and construction materials which should not be present in food packaging or child care products.

Plastic recycling is low in 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 rein 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 rein 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.

Additives can also be problematic if waste is burned, especially when burning is uncontrolled or takes place hinein low- technology incinerators, as is common in many developing countries. Incomplete combustion can cause emissions of hazardous substances such as Lysergic acid diethylamide gases and ash which can contain persistent organic pollutants (POPs) such as dioxins.[2]

The success and dominance of plastics starting in the early 20th century has caused widespread environmental problems,[3] due to their slow decomposition rate in natural ecosystems. Most plastic produced has not been reused, or is incapable of reuse, either being captured rein landfills or persisting rein the environment as plastic pollution and microplastics.

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 check here rising levels of greenhouse gases caused primarily by the burning of those fuels, the development of bioplastics is a growing field.
