Bio-based polymers provide new possibilities for a circular plastics economy. Together with experts from industry and research, the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE will discuss the potential these polymers offer, the challenges that still need to be addressed, and will demonstrate their successful conversion into industrial applications in an interactive workshop on September 15, 2026, at the DECHEMA FORUM in Frankfurt.

For the industry, recycled materials are creating new opportunities in geotextile production. In the GREEN project, the Fraunhofer Cluster of Excel-lence Circular Plastics Economy CCPE demonstrates that recycled polypro-pylene (PP), polyethylene terephthalate (PET), and high-density polyeth-ylene (HDPE) can be processed into nonwovens, fibers, and membranes that meet industrial requirements. This creates opportunities for use in existing production lines and new value chains in the geotextile market.

Metallic effects on plastic surfaces have become standard in many industries, from automotive interiors and exteriors to toys and household appliances. However, injection-molded parts with metallic effects suffer from a well-known drawback: visible flow lines that appear as streaks and compromise the premium look. A new method for producing metallic effect pigments, currently being optimized at the Fraunhofer Institute for Applied Polymer Research IAP, enables high-quality metallic effects on plastic surfaces with significantly reduced flow-line visibility – without an additional coating step.

Microcapsules containing a reactive two-component adhesive can simplify bonding processes in industry and assembly while improving occupational safety: The adhesive is initially safely enclosed in capsules, contact with exposed reactive components can be reduced, and activation takes place only during pressing at room temperature. The Fraunhofer Institute for Applied Polymer Research IAP in Potsdam Science Park is looking for partners from industry and research who would like to contribute specific components, carrier materials or assembly processes for application-oriented testing.

How can materials automatically perform protective functions in the event of a fire, and why are sustainable flame retardants becoming increasingly important? The Fraunhofer Institute for Applied Polymer Research IAP will present answers to these questions at FeuerTrutz 2026 in Nuremberg. From June 24 to 25, 2026, researchers will showcase thermoresponsive functional materials and bio-based flame retardants for fire protection applications in construction, mobility, and industry in Hall 4.

A cost-effective and multifunctional filler for paints and coatings could be obtained from chicken feathers in the future: keratin. Researchers at two Fraunhofer Institutes have achieved promising results with this protein.

Since 2025, Fraunhofer IWU has been heading the Lightweight Design Research Field. This alliance brings together the expertise of 16 Fraunhofer institutes, creating a powerful, interdisciplinary platform along the entire lightweight engineering value chain—from material development to validated application in products. The goal is to provide companies with integrated research and development services “from a single source” and to transform innovations into industrial applications.

New findings from the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE show how commercial PBSA/PLA blends can be specifically tailored through industrial processing methods to make them suitable for flexible film applications. This opens up concrete bio-based alternatives to petro-chemical plastics.

A novel developed biomimetic tissue substitute combines precisely tunable mechanical properties with biological functionality and is now ready for applications in medical technology. The material was developed in the »PolyKARD« project by the Fraunhofer Institute for Applied Polymer Research IAP and the NMI Natural and Medical Sciences Institute. From April 20 to 24, 2026, the new material will be presented together with further developments from Fraunhofer IAP at the Hannover Messe, at the Fraunhofer joint booth in Hall 11, Stand D33.

A new extruded foam made from polybutylene succinate (PBS), developed by the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE, offers industrial companies a direct path to sustainable material solutions – without the need to invest in new equipment. This approach simultaneously addresses CO₂ reduction, compliance with regulatory requirements, and economic efficiency.
