For a Sustainable Future


Simple Sustainable Recycling



Our innovative low-cost low-energy process produces terephthalic acid (TPA) and mono ethylene glycol

(MEG) from post-consumer PET plastic waste. 

We depolymerize all PET plastics including mixed color, multi-layer and polyester fibers at room temperature without

any additional heat or pressure.  

Our process can selectively treat PET plastic in the presence of other plastics like polypropylene or polyvinyl chloride,

which is the challenge of current recycling technologies. 

Our technology only involves sustainable and environmentally friendly chemicals.  



A Sustainable Circular Economy for PET



We are closing the loop on PET production by recycling post-consumer PET plastic waste.

Our products are then directly used to remade new PET plastic.

Cleaning our landfills and oceans

By implementing our technology, we are determined to recycle millions of tons of waste plastics that are polluting our natural environment back into the production system. 

Reduce reliance on oil 

Our technology can reduce our dependence on oil products in production of 100% recycled PET resins 


For every ton of plastic that we recycle, we save the equivalent of:

10 passengers flying 

London - New York

4 EU Households annual 


431 less trees being

cut down and used 

A car travelling around the world 

18 Barrels of burnt
