Carbios makes progress with depolymerisation technique

15/03/2018
Bioplastics specialist Carbios has announced a new step forward in the development of its enzymatic depolymerisation process which makes it applicable to PET polyester fibres from textile waste.

The company has managed to depolymerise 100% PET textile waste fibres back into their original monomers: PTA (terephthalic acid) and MEG (mono ethylene glycol). This means PET can be recycled ad infinitum without loss of quality in a circular loop. 

Carbios has said there are two main objectives of this new process. Firstly, it will provide a solution to upcycle post-consumer PET polyester fabrics. It will also allow the textile industry to use recycled PET fibres in place of those made from new resources. 

Alain Marty, Carbios chief scientific officer, has explained: “Turning unwanted polyester textiles into high quality raw materials for new products using Carbios enzymatic technology is an opportunity for completely changing textile manufacturing and trade in Europe and beyond. From a sustainable perspective, our approach will significantly improve the overall life cycle impact of textile products.”
