The new DIN SPEC 91481 is intended to promote the use of recycled plastics and contains a concept for a digital product passport.

According to the consortium of 19 organizations from research and industry, DIN SPEC 91481, which builds on DIN SPEC 91446, is intended to increase the use of recycled polyamide (PA) in the long term. According to the information provided, the new standard describes specific requirements for the classification of PA plastic recyclates and waste for their use and (internet-based) trade. The document is aimed at the manufacturing and processing industry and is intended to facilitate trade in PA waste and recyclates. DIN SPEC 91481 also contains a concept for a digital product passport. According to the developers, this will ensure comprehensive data collection and processing from raw materials through to the compound. The aim is to make the entire life cycle of the material traceable.
"DIN SPEC 91481 goes beyond the previous standards on the market in key respects: for the first time, it focuses on polyamide as a material, records both waste and recyclates and opens the door to significantly more digitalization in the circular economy," explains Christian Schiller, founder and Managing Director of Cirplus, a Hamburg-based online trading platform for recyclates and plastic waste, which reportedly initiated and financed the development of the standard. "The new DIN SPEC is an opportunity for all stakeholders in the recycling value chain, including in the field of technical plastic recyclates, to remove current obstacles in terms of both quantity and quality. This can make a significant contribution to defossilization and a more CO2-neutral circular economy in the plastics industry," adds Prof. Dr.-Ing. Hans-Josef Endres, Head of the IKK Institute for Plastics and Recycling Technology at the University of Hanover and consortium leader of DIN SPEC 91481 as well as the previous DIN SPEC 91446.
According to Cirplus, the following organizations and companies contributed to the development of the standard: Under the leadership of IKK - Institut für Kunststoff- und Kreislauftechnik Hannover and Kunststoffinstitut Lüdenscheid as well as Cirplus GmbH as deputy, there were involved Greiner Packaging GmbH, Polifilm Extrusion GmbH, DSD GmbH (Der grüne Punkt), Remondis Recycling GmbH & Co. KG, MKV GmbH, Krauss Maffei, MRS Materials Recycling Solutions GmbH, Steinert GmbH, Tomra Sorting GmbH, the Süddeutsche Kunststoff-Zentrum (SKZ), the Institute for Plastics Processing (IKV) in Industry and Trade at RWTH Aachen University, the VDMA Association of German Machine and Plant Manufacturers and the BDE Federal Association of the German Waste, Water and Raw Materials Management Industry.
