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 hinein the global East and West. The plastic industry comprises a huge number of companies and can be divided into several sectors:

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.

Plastics are produced in chemical plants by the polymerization of their starting materials (monomers); which are almost always petrochemical rein 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.

Some companies produce biodegradable additives to enhance biodegradation. Although starch powder can be added as a filler to allow some plastics to degrade more easily, such treatment does not lead to complete breakdown. Some researchers have genetically engineered bacteria to synthesize completely biodegradable plastics, such as polyhydroxy butyrate (PHB); however, these were lautlos relatively costly as of 2021.[23]

Plasticity also has a technical definition hinein materials science outside the scope of this article referring to the non-reversible change rein form of solid substances.

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 check here 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 Durchschuss and color before recycling.[2]

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.

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]
