The world's first eco-friendly optical discs made from corn will become available to consumers by December of this year, say Sanyo researchers who claim to have found a way to create 10 high quality compact discs from a single corncob. Named "MildDisc" by Sanyo Mavic, it is equal to conventional plastic optical discs in quality and produces no dioxin or other hazardous material when it is burnt. Moreover, MildDiscs can be degraded into the harmless soil by using micro-organisms. Researchers at Sanyo Mavic and its partner Mitsui Chemicals, Inc. invented a method to produce discs from polylactic acid extracted from corn. Nice.
