Textile waste could serve as a valuable source of raw materials for sustainable plastics in the future, according to the joint TexPHB feasibility study conducted by the Fraunhofer Institute for Applied Polymer Research IAP, Beneficial Design Institute GmbH and matterr GmbH. The study will be presented to the public for the first time at a network meeting on 25 November 2025 at the State Chancellery in Potsdam.

Efficient use of methane and CO₂ from biogas: Thanks to novel flat membranes, biogas can be processed directly and energy-efficiently – even in small plants. In the Bio4Value project, the Fraunhofer Institute for Applied Polymer Research IAP in the Potsdam Science Park, together with KS Kunststoffbau GmbH and the Leibniz Institute for Agricultural Engineering and Bioeconomy ATB, is developing a technology that opens new perspectives for the material use of methane and CO₂.

Those who want to generate electricity for their own consumption using wind power need a powerful small wind turbine. Researchers at the Fraunhofer Institute for Applied Polymer Research IAP, in collaboration with the BBF Group, have developed a lightweight rotor that is specifically designed for operation in regions with low wind speeds. The first prototypes have now been delivered. These systems enable private households, businesses, or disaster relief organizations to set up a decentralized energy supply and use renewable energy efficiently.

How can the state of Brandenburg benefit from a circular textile industry? This question is addressed in the new policy paper "Closing the loop in the textile industry: Value creation in the state of Brandenburg." Based on the „TexPHB“ feasibility study funded by the Brandenburg Ministry of Climate Protection, it shows how textile waste can be integrated into new value chains.

How can new bio-based and biohybrid materials with improved features be developed faster? Six Fraunhofer institutes are jointly exploring this question in the SUBI²MA flagship project, using an innovative bio-based polyamide developed by Fraunhofer researchers as a model. Its specific properties make it a promising alternative to fossil-based plastics.

Stents are used to remove narrowings (stenosis) in blood vessels, stabilize the vessels and thus prevent heart attacks or strokes. However, the implantation process damages the inner wall of blood vessel, and in addition a foreign body material is inserted into the blood vessel wall. Both factors can contribute to restenosis of the affected vessel. Researchers at the Fraunhofer Institute for Applied Polymer Research IAP at Potsdam Science Park aim to address these issues with specially coated, biocompatible, degradable stents. The team won recognition for developing a prototype as part of the senetics Innovation Award 2025.

An innovative chemical process developed by the Fraunhofer Institute for Applied Polymer Research IAP enables the complete recycling of particleboards. In collaboration with the Eberswalde University for Sustainable Development HNEE, System 180 GmbH, and PreZero Holz GmbH, the institute has demonstrated that new wood components can be produced without the use of virgin material. The project was funded by the Agency for Renewable Resources FNR through the Federal Ministry of Food, Agriculture and Home Affairs BMLEH.

Bioplastics have been at the center of the search for environmentally friendly alternatives to conventional plastics for many years. They can reduce the demand for fossil raw materials, conserve resources, and help lower CO₂ emissions. For industrial applications, however, they should not only be sustainable, but also easy to process. This is precisely what the Fraunhofer Institute for Applied Polymer Research IAP in the Potsdam Science Park is working on, and it will be presenting its developments in the field of bio-based and biodegradable plastics at K 2025, the international trade fair for the plastics and rubber industry.

Whether in hydrogen tanks, batteries, fuel cells or for shielding sensitive electronics – carbon fibers are used in a wide range of advanced applications. At the Potsdam Science Park, the Fraunhofer Institute for Applied Polymer Research IAP, in collaboration with Brandenburg University of Technology Cottbus-Senftenberg, is developing novel carbon fibers based on cellulose. These fibers combine structural diversity, high electrical, thermal and mechanical performance with sustainability. The project is part of the Carbon Lab Factory Lausitz and is funded by the German Federal Ministry for Economic Affairs and Energy. It is intensively supported by the Wirtschaftsregion Lausitz GmbH.

Electroactive polymers react to forces, deformations, and temperature changes with electrical signals. They can also deform or change their temperature under electrical voltage. Targeted temperature changes are particularly interesting for heating and cooling systems. Electrocaloric polymers are the key to this. Researchers at the Fraunhofer Institute for Applied Polymer Research IAP are developing electrocaloric materials and processing them into functional components. As the heart of an optimized overall system, they are an important basis for the future development of efficient and compact heating and cooling systems that do not require harmful refrigerants.
