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 ...
Boxed products made from bioplastics and other biodegradable plastics. Few commercial applications exist for bioplastics. Cost and performance remain problematic. Typical is the example of Italy, where biodegradable plastic bags are compulsory for shoppers since 2011 with the introduction of a specific law. [16]
In typical parlance, the word biodegradable is distinct in meaning from compostable.While biodegradable simply means an object is capable of being decomposed by bacteria or other living organisms, "compostable" in the plastic industry is defined as able to decompose in aerobic environments that are maintained under specific controlled temperature and humidity conditions.
Plastic recycling improves usage of resources. Biodegradable films need to be kept away from the usual recycling stream to prevent contaminating the polymers to be recycled. If disposed of in a sanitary landfill, most traditional plastics do not readily decompose. The conditions of a sealed landfill additionally deter degradation of ...
Biodegradable polymers also received notice from various fields in 2012 when Professor Geoffrey Coates of Cornell University received the Presidential Green Chemistry Challenge Award. As of 2013, 5-10% of the plastic market focused on biodegradable polymer derived plastics. [citation needed]

Biodegradable waste can be found in municipal solid waste (sometimes called biodegradable municipal waste, or as green waste, food waste, paper waste and biodegradable plastics). Other biodegradable wastes include human waste, manure, sewage, sewage sludge and slaughterhouse waste. In the absence of oxygen, much of this waste will decay to ...
As PBS decomposes into water and CO 2 through naturally occurring degrading enzymes and microorganisms, [10] it may be a biodegradable alternative to some common plastics. The scope of PBS application fields is still growing and several areas can be identified but it remains difficult to know precisely in which specific object PBS is actually used.
