PLA aka Bioplastic is a very unique material since it is made from corn and not from petroleum. Regular plastics is made from petroleum while PLA is made from corn based resins which makes PLA non toxic and annually renewable resources
PLA break down into its constituent parts (carbon dioxide and water) within three months in a “controlled composting environment,” that is, an industrial composting facility heated to 60degrees Celsius and fed a steady diet of digestive microbes.
Polylactide is biodegradable, as it decays as a result of exposure to the ultra violet rays of sunlight and oxygen. It decomposes forming carbon dioxide and water, which present no danger to the environment.
PLA is technically “carbon neutral” in that it comes from renewable, carbon-absorbing plants—as yet another way to reduce our emissions of greenhouse gases in a quickly warming world.
PLA also will not emit toxic fumes when incinerated.
