Disposable plastic cups made from biodegradable plastic. Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass. [1] Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all ...
Almost all plastic is non-biodegradable and without recycling, spreads across the environment [109] [110] where it causes plastic pollution. For example, as of 2015, approximately 8 million tonnes of waste plastic enters the oceans annually, damaging oceanic ecosystems and forming ocean garbage patches .
In 2011 and 2013, Kauai, Maui and Hawaii prohibit non-biodegradable plastic bags at checkout as well as paper bags containing less than 40 percent recycled material. In 2015, Honolulu was the last major county approving the ban.
Plastic recycling is the processing of plastic waste into other products. [1] [2] [3] Recycling can reduce dependence on landfill, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. [4] [5] [6] Recycling rates lag behind those of other recoverable materials, such as aluminium, glass and paper.
An effort that will take time, money and some convincing in a society that relies heavily on plastics for just about everything we do. “Microplastics aren’t going to kill us tomorrow or today ...
The term Biodegradable Plastics refers to materials that maintain their mechanical strength during practical use but break down into low-weight compounds and non-toxic byproducts after their use. [18] This breakdown is made possible through an attack of microorganisms on the material, which is typically a non-water-soluble polymer. [4]
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.

By Lily Fink Harrington Plastic grocery bags are so money, and you don't even know it. Not that I agree with the production of non-biodegradable bags in the first place. But since the world is ...
