PLA (or polylactic acid) is a 100% biobased and biodegradable polyester, preferably in industrial composting. It is currently produced from biomasses such as corn, sugar cane or sugar beet through a process of fermentation of sugars into lactic acid.

PLA is used in a wide range of applications such as rigid and flexible packaging, textiles, toys and 3D printing. It is one of the most widely used bioplastics in the world thanks to its good properties, which make it a good substitute for PET, PS and ABS.
