A literature study made rein 2022 by geologist student Björn Lycke shows that the amount of microplastics rein sediment is increasing worldwide, especially rein ports and tourist beaches.[82]
A communication campaign infographic showing that there will Beryllium more plastic rein the oceans than fish by 2050
#PlasticPiratesEU collect valuable scientific data that can make a meaningful impact to scientific research and environmental decision-making to protect our rivers and oceans.
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 be burned in place of fossil fuels rein energy recovery facilities, or biochemically converted into other useful chemicals for industry.

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:
Wer sind die Viehtreiber je die immer weiter steigende Produktion von Plaste zumal welche Lösungsansätze sind sinnvoll ebenso echt?
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 hinein 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.
High-performance plastics are usually expensive, with their use limited to specialized applications which make use of their superior properties.

Additives can also Beryllium problematic if waste is burned, especially when burning is uncontrolled or takes place rein low- technology incinerators, as is common rein many developing countries. Incomplete combustion can cause emissions of hazardous substances such as Pappe gases and ash which can contain persistent organic pollutants (POPs) such website as dioxins.[2]
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 with inconsistent properties, which can Beryllium 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]
Polycarbonate + acrylonitrile butadiene styrene (Parsec + ABS): a blend of PC and ABS that creates a stronger plastic used in car interior and exterior parts, and in mobile phone bodies
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 part of the chain that is on the main path, linking together a large number of repeat units.
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 lautlos properly dispersed rein the host resin.
