RITTEC Umwelttechnik is your partner for managing recycling in the world of plastics. With our patented revolPET® technology, we develop methods that enable PET to be completely recycled and given new life, again and again.

Our motivation is to find solutions to conserve finite resources. Our research-intensive developments meet the highest standards in terms of innovation, economic efficiency and environmental protection.

The result is smart solutions for the many diverse forms of PET plastic. We specialise in coloured bottles, multi-layer packaging and polyester textiles.


Empty juice bottles, cheese packaging, to-go boxes, polyester textiles: the RITTEC team sees great opportunities for raw materials where many people imagine filthy cities and seas. With their PET circular economy project "revolBRAS" they were granted with the titel of "Startups Connected 2022" competition, awarded on September 29, 2022 at the 10th German-Brazilian Congress for Innovation and Sustainability...

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.
