Large areas of land are currently covered in plastic waste. Biodegradable additives will help speed up the biodegradation process of plastics so that plastic pileups will be less frequent. [19] Biodegradable additives have the potential to significantly reduce the accumulation of plastics in the environment.
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 be burned in place of fossil fuels in energy recovery facilities , or biochemically converted into other useful chemicals for industry. [ 14 ]
Lignin contains comparable chemical properties in comparison to current plastic chemicals, which includes reactive functional groups, the ability to form into films, high carbon percentage, and it shows versatility in relation to various chemical mixtures used with plastics. Lignin is also stable, and contains aromatic rings.
LONDON (Reuters) -At least 3,000 more chemicals are in plastics — from food packaging to toys to medical devices — than previously estimated by environmental agencies, a report published on ...
It is estimated that this waste is made up of 81% polymer resin, 13% polymer fibers and 32% additives. In 2018 more than 343 million tons of plastic waste were generated, 90% of which was composed of post-consumer plastic waste (industrial, agricultural, commercial and municipal plastic waste).
Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling.
