Petshka is an R&D company based in France. Its focus is green chemical innovation driving sustainability and circularity.

It collaborates with the Centre National de la Recherche Scientifique to drive innovation. After three years of research, in 2024 they successfully devised a process for turning polyester waste into recycled polyol polyester.

It is an efficient process based on industrial symbiosis:

• They partner with businesses to collect their polyester waste, such as clothing, textile waste and packaging.
• Their patented process converts PET into polyol polyester through a low-temperature, low-pressure chemical recycling method that releases only water, with no pollution or waste.
• The resulting polyol polyester has various industrial applications, such as polyurethane production (it is used in insulation materials), coatings and adhesives (it is a base material for these), the textile industry (it is used in manufacturing synthetic fibers) and construction materials (it is used in insulation products and sealants).

The recycled polyol is of a high standard: it has been awarded various international recycling certificates and is suitable for a wide range of applications. Petshka tailors reycling solutions to each client – after all, every business is different.

Petshka has put its theory into effect by working with TPF to create a more sustainable polyurethane foam. Its recycled polyol polyester replaced 25% of their virgin oil-sourced chemical components. The company began collection and production in Europe in 2024 and plans to expand operations to North America by 2025.
