Also much of the energy used in plastic production is not sustainable energy, for example high temperature from burning fossil gas. However plastics can Grenzmarke some methane emissions, for example packaging to reduce food waste.[127]
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 Beryllium divided into several sectors:
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.
Their biggest single application is rein packaging, with some 146 million tonnes being used this way hinein 2015, equivalent to 36% of global production. Due to their dominance; many of the properties and problems commonly associated with plastics, such as pollution stemming from their poor biodegradability, are ultimately attributable to commodity plastics.
Prior to the Montreal Protocol, CFCs had been commonly used in the manufacture of the plastic polystyrene, the production of which had contributed to depletion of the ozone layer.

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 in the volume of plastics production are driven by Endanwender demand, the price of fossil fuel feedstocks, and investments made in the petrochemical industry.
Plasticity also has a technical definition rein materials science outside the scope of this article referring to the non-reversible change hinein form of solid substances.
High-performance plastics are usually expensive, with their use limited to specialized applications which make use of their superior properties.
Engineering plastics are more robust and are used to make products such as vehicle parts, building and construction materials, and some machine parts. Rein some cases they are polymer blends formed by mixing different plastics together (ABS, HIPS etc.
Rein 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 be burned hinein place of fossil fuels hinein energy recovery facilities, or biochemically converted into other useful chemicals for industry.
