Bio­plas­tics

The circular economy is a central concept aiming at efficiently utilizing resources, minimizing waste, and keeping materials in the economic cycle for as long as possible. Fraunhofer CCPE works intensively to implement these principles in practice and develop innovative solutions for a sustainable future. A key component of the circular economy is the recycling and reuse of materials and components. By closing product and material loops, valuable resources can be saved and environmental impact reduced. Fraunhofer CCPE relies on cutting-edge technologies and interdisciplinary research to achieve these goals.

We examine the diversity of renewable raw materials, recyclable polymers, and their potential for bioplastic production. Renewable raw materials such as corn starch, sugar cane, cellulose, and algae offer a sustainable alternative to fossil raw materials. The materials produced from them are not only renewable, they can also be biodegradable, which increases their environmental compatibility.

Controlling and accelerating plastic degradation is a research area at Fraunhofer CCPE. Through the use of additives that control plastic degradation, we can specifically extend or shorten product lifespan according to application requirements.

Fraunhofer CCPE investigates composites from thermally more resistant scPLA filaments and a chemically identical PLA matrix. Here, a fabric from scPLA-PLA blended yarn is formed into self-reinforced organo-sheets. The goal is developing PLA-based single-component composite materials for technical applications. In recycling processes, these materials have a clear advantage over established fiber-reinforced systems and thus offer an option for obtaining recyclable composite materials.
