Masterbatch granules can Beryllium mixed with cheaper bulk polymer and will release their additives during processing to give a homogeneous final product. This can Beryllium cheaper than working with a fully compounded material and is particularly common for the introduction of color.
Engineering plastics are more robust and are used to make products such as vehicle parts, building and construction materials, and some machine parts. Hinein some cases they are polymer blends formed by mixing different plastics together (ABS, HIPS etc.
Efforts to minimize environmental impact of plastics may include lowering of plastics production and use, waste- and recycling-policies, and the proactive development and deployment of alternatives to plastics such as for sustainable packaging.
In 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 hinein energy recovery facilities, or biochemically converted into other useful chemicals for industry.
In 2023, plasticosis, a new disease caused solely by plastics, welches discovered hinein seabirds. The birds identified as having the disease have scarred digestive tracts from ingesting plastic waste.
Plastic recycling is low hinein the waste hierarchy, meaning that reduction and reuse are more favourable and long-term solutions for sustainability.

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]
High-performance plastics are usually expensive, with their use limited to specialized applications which make use of their superior properties.
Some companies produce biodegradable additives to enhance biodegradation. Although starch powder can Beryllium 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 still relatively costly as of 2021.[23]
The effect of plastics on global warming is mixed. Plastics are generally made from fossil gas or petroleum, thus the production of plastics creates further fugitive emissions of methane when the fossil gas or petroleum is produced.
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.

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.
