Chemical plastic products bring people all kinds of convenience, but also bring unimaginable trouble. As some waste plastics will not degrade under natural conditions, the combustion will release harmful gases, causing difficult pollution to the ecological environment. So scientists around the world are starting to develop self-destructing, or autolytic, plastics that can break down on their own to solve the problem. Some call it "green plastic". Companies in many countries have introduced their own biodegradable plastics. Biologists at the University of Mitzgan in the United States first proposed the idea of "growing" degradable plastics. Using potatoes and corn as raw materials, they inserted the plastic's genetic material so that it could be artificially grown without harmful ingredients. Imperial Chemical Forests USES bacteria to make sugars and organic acids into biodegradable plastics. The method is similar to the fermentation process used to produce ethanol, except that the bacteria, alkaloids, turn the feed into a plastic called PHBV. Bacteria accumulate the plastic as a store of energy, just as humans and animals store fat. When the bacteria have accumulated as much as 80% of their body weight in PHBV, they break down the cells with steam to collect the plastic. PHBV has properties similar to polypropylene, a material that is stable even in humid environments after being discarded, but which degrades into carbon dioxide and water in the presence of microorganisms.
