revolPET® A cycle for plastic

We developed our new revolPET® technology for high quality recycling of PET plastics. Waste PET is dissolved into its constituent monomers, which are then available to create PET with the same quality as totally new product. This monomer production method ensures complete raw material conservation. Turning old into new.


revolTEX® solution for textiles containing polyester

In 2000, polyester replaced cotton as the leading fibre used in textile manufacture. Now, 20 years later, polyester production has doubled compared to what it was back in 2000. Over 60 percent of PET production is processed into polyester fibres and finds its way into the textile industry.
