At just under one percent, the share of bio-based plastics on the global market is still very low. However, the global plastics industry is changing. Renewable raw and residual materials are increasingly coming into focus. In the Bio-Polyols project, researchers at Bielefeld University, together with an industrial partner, have now developed a process to produce the important plastic group of polyurethanes from domestic vegetable oils and make them usable for high-performance composites.
Batteries made from wood waste
They are small, light and long-lasting and therefore extremely popular: lithium-ion batteries. These powerful energy sources are not only found in many electronic devices such as cell phones, laptops and digital cameras. The automotive industry also mostly relies on lithium-ion batteries for the production of electric cars. The problem is that lithium is only available in limited quantities and has to be imported. Mining the raw material is also often problematic for both people and the environment.
