Biodegradable super materials are widely used in the current stage, some of them are made from renewable natural resources, such as food crops, microorganisms, etc., and some of them are made from fossilized animal resources. The two prevalent fully bioplastics that have long been commercialized are PHA and PLA, each of which is made from microorganisms and rice. Degradable plastics are made by wrapping an initiator around the plastic, which slowly dissolves under the effect of direct sunlight, but the drawback is that degradable materials are not controlled because they are subjected to the hazards of sunlight and weather conditions. Degradation refers to the wave of nature has to do biological, such as germs, yellow dew bacteria and algae blocking material, etc., under certain conditions dissolved into low molecular structure of the chemical substance of the plastic. This type of plastic is easy to store and transport, and has a wide range of applications.
Light/biodegradation, that is, the combination of light peak decomposition of plastic and biodegradable material two-way special plastic. At the present price, in China's development of biodegradable plastic judgment is mainly bio-based polypolymer polylactic acid (LA), polyethylene glycol acid (PHA), dioxide polymer (PPC) and so on. Polylactic acid (PLA) is obtained from the green plant sugar two cross cool single convergence, in industrial production under the fertilizer can be completely degraded to water and carbon dioxide.
