A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44] An example of a non-biodegradable bioplastic is bio-based PET. PET is a petrochemical plastic, derived from ...
2007: Metabolix inc. market tests its first 100% biodegradable plastic called Mirel, made from corn sugar fermentation and genetically engineered bacteria. (Digregorio 2009) [ 100 ] 2012: A bioplastic is developed from seaweed proving to be one of the most environmentally friendly bioplastics based on research published in the journal of ...
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.
Biodegradable polymers are mostly plant-base materials, which means they originally come from organic source like soybean or corn. These organic plants have the chance to be sprayed with pesticides which contain chemicals which can contaminate the crops and be transferred into the final finished product.

Alginates are the natural product of brown algae and have been used extensively in wound dressing, drug delivery and tissue engineering, as well as food applications. [ 9 ] [ 10 ] [ 11 ] Sodium alginate is an unbranched copolymer of 1,4-linked-β-d-mannuronate (M) and α-l-guluronate (G) sugars.
In a study of 259 plastic water bottles at the State University of New York at Fredonia, scientists found that 93% of the surveyed bottles had some form of microplastic contamination.
Scientists studying how tiny particles of plastic affect our everyday lives say that the amount of nanoplastics found in bottled water is between 10 to 100 times higher than researchers had ...
