Soft drinks giants PepsiCo, Nestle Waters and Lucozade Ribena Suntory’s (LRS) parent brand Suntory Beverage & Food Europe have thrown their support behind a new plastics recycling technology which uses enzymes to process waste.

Developed by French green chemistry firm Carbios, the method involves applying a liquid mixture of enzymes to used PET plastics and polyester fibres. Through a reaction similar to digestion, the enzymes break the polymers down into monomers – single-element particles which are then sent through a filtration and purification system.

The resulting materials are of “equivalent quality” to virgin PET, according to Carbios, making them ready for reuse in new plastic packaging such as drinks bottles.
