Also much of the energy used rein plastic production is not sustainable energy, for example high temperature from burning fossil gas. However plastics can limit 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 in the global East and West. The plastic industry comprises a huge number of companies and can be 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 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.

Their biggest single application is in packaging, with some 146 million tonnes being used this way rein 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 hinein 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 hinein the volume of plastics production are driven by Endanwender demand, the price of fossil fuel feedstocks, and investments made hinein the petrochemical industry.

The concentrations of most additives are usually quite low, however high levels can be added to create Masterbatch products. The additives rein these are concentrated but still properly dispersed hinein the host resin.

High-performance plastics are usually expensive, with their use limited to specialized applications which make use of their superior properties.

Waste plastic, even if it is all of the same polymer Durchschuss, will contain varying types and amounts of additives. Mixing these together can give a material read more 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]

Hinein 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 rein place of fossil fuels in energy recovery facilities, or biochemically converted into other useful chemicals for industry.

Pre-exposure of the plastic to ultraviolet radiation broke chemical bonds and aided biodegradation; the longer the period of UV exposure, the greater the promotion of the degradation.[96]
