Gr3n SA is a Swiss company established in 2013. The company developed an innovative process, based on a new application of microwave technology to provide an efficient chemical recycling process of PET and polyester textile allowing an industrial implementation of this recycling method.

The robustness of the whole process allows to treat highly contaminated materials upcycling the PET recycling. The recycling process of gr3n produces the same monomers used for conventional synthesis of PET exploiting a full integration with the existing value chain of PET. The process is economically competitive with oil-based production of PET but creating a huge benefit for the environment.
