Polylactic acid, or polylactide (PLA) is a thermoplastic polyester with backbone formula, formally obtained by condensation of lactic acid with loss of water. It can also be prepared by ring-opening polymerization of lactide, the cyclic dimer of the basic repeating unit.

PLA has become a popular material due to it being economically produced from renewable resources.

Degradation

Possible end of life scenarios are the most common:
1. Recycling: Polylactic acid can be chemically recycled to monomer by thermal depolymerization or hydrolysis. When purified, the monomer can be used for the manufacturing of virgin PLA with no loss of original properties(cradle-to-cradle recycling).
2. Composting: PLA is biodegradable under industrial composting conditions, starting with chemical hydrolysis process, by the microbial digestion, to ultimately degrade the PLA.
3. Incineration: PLA can be incinerated, leaving no residue and producing 19.5 MJ/kg (8,368 btu/lb) of energy.
4. Landfill: the least preferable option is landfilling because PLA degrades very slowly in ambient temperatures.
