Poly(lactic acid) or polylactide (PLA) is a biodegradable thermoplastic aliphatic polyester derived from renewable resources, such as corn starch (in the United States), tapioca roots, chips or starch (mostly in Asia), or sugarcane (in the rest of the world).[2]

Plastic in a circular economy

Scientists have developed an ingenious idea that promises to be a solution to the Dilemma of downcycling. They are working on a plastic that acts like a set of Lego, in that its components can be taken apart at the molecular level and can then put back together again in new forms, textures and colours without any loss of performance and quality.
