Sustainable Innovation without Production Restructuring
According to the press release, the „xPBS“ project has developed a bio-based extrusion foam made from polybutylene succinate (PBS) that can replace conventional petroleum-based materials such as polyethylene. Fraunhofer states that the new foam is suitable for applications in packaging, transport solutions, and construction, areas with high demand.
According to the press release, it is particularly important that it is a so-called drop-in solution. This means that companies can process the new foam using existing production facilities without having to invest in expensive conversions. This is intended to make the transition to more sustainable materials significantly easier.
Co-operation and technical capability
According to Fraunhofer, the project's success is based on the close collaboration of several institutes within Fraunhofer CCPE. While one institute drove material development, another focused on adapting properties and industrial scaling.
According to the press release, this has made it possible to develop a foam that works not only in the laboratory but also under realistic production conditions. Furthermore, the material achieves comparable properties to established plastics, particularly regarding density and processability, making it versatile.
Ecological benefits and market potential
According to the press release, the new PBS foam offers clear ecological advantages: it is bio-based, biodegradable, and recyclable. Companies can thus achieve their sustainability goals without compromising on performance.
According to Fraunhofer, the technology's proximity to the market enables rapid industrial adoption with low risk. At the same time, companies can meet regulatory requirements early on and secure competitive advantages.
According to the press release, the follow-up project „xPBS-food“ will also work on a food-grade packaging solution. This opens up another high-growth application area and underscores the potential of the technology for future markets.
