Non-biodegradable polymers derived from renewable resources

Some polymer materials are produced wholly or partly from renewable (the term renewable here is very limited, as was previously explained) raw materials. Some examples are listed below. Braskem - green polyethylene: is the traditional polyethylene, but derived from ethylene produced with ethanol from sugar cane. DuPont - PTT - poly(trimethylene terephthalate): one of its monomers, 1,3-propanediol, is obtained from corn or sugar beets. Coca-Cola Co: PlantBottle: PET bottle made from ethylene glycol obtained from alcohol derived from sugar cane and molasses. In addition, the PP cap is slightly smaller. The proportion of raw materials obtained from fossil fuels (oil, coal and gas) and obtained from plants can be found through analysis of the proportion of carbon-12 to carbon-14 present in the polymer, since fossil fuels contain virtually no carbon-14 whose half-life is about 5730 years
