PLA (Poly Lactic Acid) is made from extracted starch of surplus crops and genetic modified plants, and becomes a new type of material through some complex chemical processes. PLA is completely natural and it won’t make any air pollution when it burned. Compared with plastic products, PLA reduces the consumption of fossil fuel during production process. PLA can be composted under specifically built bury facility and decomposed into H2O and CO2. The PLA material works fine with bright/vivid colors.
