How can we make chemicals in products more traceable and thus move closer to a climate-neutral and resource-conserving circular economy? This is the core question of the "ECHT" project led by Jonas Rehn-Groenendijk from the Innovation and Transformation Platform for Sustainable Development at h_da. In the context of the European Green Deal and the introduction of the Digital Product Passport, the aim is to initiate a transformation in close cooperation with companies from the textile industry. The results at the halfway point of the project are encouraging.
