Non-biodegradable waste will NOT break down or at least NOT break down for many years. Examples of Non-biodegradable are plastics‚ metal and glass. Dangerous chemicals and toxins are also non-biodegradable‚ as are plastic grocery bags‚ plastic water bottles and other similar materials. Non-biodegradable trash has been a growing concern to environmentalists‚ but now is becoming a concern to anyone wanting to embrace a more eco-friendly lifestyle; as world population grows so does our waste. It’s

Science Investigatory Project How to make a Biodegradable Plastic using cassava starch? ABSTRACT The study aims to produce biodegradable plastic using cassava starch as its main component. Cassava starch was mixed with water‚ epoxydized soya beanoil (ESBO)‚ glycerol‚ and polyvinyl alcohol (PVA). The mixture was then compressed and tested. Three preparations were made from the mixture. The first preparation contained 50 grams starch‚ 50 grams water‚ 50 grams PVA‚ 2.5 grams ESBO‚ and 2.5 grams

plastic industry in the US alone is $ 50 billion per year and is obviously a tempting market for biotechnological enterprises. Biotechnological processes are being developed as an alternative to existing route or to get new biodegradable biopolymers. 20% of solid municipal wastes in US is plastic. Non-degradable plastics accumulate at the rate of 25 million tones per year. According to an estimate more than 100 million tones of plastic is

[1] Biodegradable plastics are plastics that are capable of being decomposed by bacteria or other living organisms. Two basic classes of biodegradable plastics exist:[1] Bioplastics‚ whose components are derived from renewable raw materials and plastics made from petrochemicals with biodegradable additives which enhance biodegradation There are concerns that "Oxo Biodegradable (OBD)" plastic bags may release metals‚ and
