DSM, Clariter to Pursue Chemical Recycling Solution for Dyneema-based End-products

Royal DSM, a global science-based company in nutrition, health and sustainable living, will partner with Clariter, an international clean-tech company, to pursue a next-generation chemical recycling solution for products based on DSM’s Dyneema, an ultra-high-molecular-weight polyethylene fiber.

As a first step, sample products – including ropes, nets, and ballistic materials made with Dyneema – were converted at Clariter’s pilot plant in Poland, demonstrating the recyclability potential of Dyneema and underlining the commitment of DSM Protective Materials to shape a more sustainable world.

In line with its sustainability targets and following the launch of bio-based Dyneema (mass balance), DSM Protective Materials is pursuing reuse and recycling solutions for end-of-life Dyneema-based products. To drive technical recycling solutions, DSM Protective Materials and Clariter tested the feasibility of using Dyneema as a feedstock in Clariter’s chemical recycling process.

The positive results confirm the technical viability of transforming Dyneema-based end-products into high-value, industrial grade, product families: oils, waxes, and solvents via Clariter’s patented three-step chemical recycling process. These can be used as ingredients to manufacture new end- and consumer products.

Moving forward, DSM Protective Materials and Clariter will drive the initiative to shape a more sustainable world. Specifically, building on the success of the lab-scale trial, Clariter has scheduled commercial-scale trials at its facility in South Africa for 2021, with the aim to use Dyneema-derived feedstock in its full-scale European plants that will be built in the coming years. In addition, DSM will continue to explore the possibilities of reducing the environmental impact of Dyneema across all product life stages.
