Cycle-Logic: upcycling of PET plastic bottles

Rudolf Group implements the manufacturing of chemical auxiliaries for textile based on chemically recycled PET plastic waste.

One of the most advanced and progressive frontiers of textile chemistry is the transformation of waste into materials that can be further used for a greener and sustainable world. The majority of the research work in this area concerns organic waste which can be upcycled into bio-carbon based innovation. The Rudolf Group currently addresses this progressive field through their recently launched Bio-Logic brand.

Rudolf Group renews its commitment to the environment through the launch of the Cycle-Logic brand and product family. Cycle-Logic captures tremendous technical innovation and pioneers a new path: the upcycling of post-consumer, disposable and non-returnable plastics – such as beverage PET plastic bottles – into valuable textile chemistry. PET plastics can now be recycled to raw materials used as inputs in Rudolf’s manufacturing and therefore partially replacing fossil resources.

The first 3 Cycle-Logic chemical auxiliaries for textiles based on post-consumer, recycled PET bottles:

  • Feran Upcycle ICT: the first intelligent moisture management technology for PES textiles

  • Rucogen Upcycle RNB: most advanced dispersing agent for indigo washing

  • Rucolin Upcycle SDS: first, all-in-one, multi-functional, high-affinity polymer dyeing auxiliary

  • Rudolf Group: The company with 1,745 employees in 45 countries is specialized in innovative and high-quality chemical products, predominantly textile auxiliaries, products for textile care as well as construction chemicals.
