Project Clean Cups has been completed. We look back on an intensive and educational journey in which we made great strides in the development of compostable coffee pods and biopolymer applications. Thanks to the ERDF for their support, trust, and pleasant cooperation. Due to the new EU Packaging and Packaging Waste Directive, the market potential for cold- or home-compostable coffee pods unfortunately appears limited. We will take the knowledge and insights gained with us to future innovations.
