However, bioplastics exert higher aquatic ecotoxicity than conventional materials. [64] Bioplastics and other bio-based materials increase stratospheric ozone depletion compared to conventional plastics; this is a result of nitrous oxide emissions during fertilizer application during industrial farming for biomass production. [64]
An example of a non-biodegradable bioplastic is bio-based PET. PET is a petrochemical plastic, derived from fossil fuels. ... All materials are inherently ...

Cornplast is a material whose composition is 20% polyethylene and 80% starch. 50%-50% by weight blends of Cornplast with both LDPE and HDPE have been studied to determine the effectiveness of starch as a biodegradable additive.
PLA has become a popular material due to it being economically produced from renewable resources and the possibility to use it for compostable products. [3] In 2022, PLA had the highest consumption volume of any bioplastic of the world, with a share of ca. 26 % of total bioplastic demand. [4]
More than 150 different monomers can be combined within this family to give materials with extremely different properties. [2] These plastics are biodegradable and are used in the production of bioplastics. [3] They can be either thermoplastic or elastomeric materials, [citation needed] with melting points ranging from 40 to 180 °C. [citation ...
This is a list of companies that produce bioplastics. It may be incomplete. BASF; Braskem; BioSphere Plastic; Danimer Scientific; DuPont; Innovia Films; NatureWorks;
Polyhydroxyalkanoatesas an example, have a degradation period for up to three to six months. Last, the cost issue. The production technology of biodegradable polymer is still immature, the cost of resources such as labor and raw materials in large production quantity scale will be comparably high.
