“Example of bioeconomy. In the "Krünstoff" buckets from Oberhofer Kunststofftechnik in Schönau / Odenwald, you can still smell the grass after the injection molding process. The word "Krünstoff" is intended to refer to green plastic that the company uses in everyday products. A 30 percent grass content is added to the plastic. But bioplastics are not bioplastics, "warns managing director Timm Oberhofer. The Krünstoff buckets from Schönau are bio-based, but should not be degradable but rather durable. Plastic bags, on the other hand, should be bio-based, but at the same time be rapidly degradable. Numerous test runs on this topic have optimized the products for their respective areas of application, says Oberhofer. Professor Peter Kunz, University of Mannheim, brought an example of organic mering with him. The hunt for rare metals and other raw materials has long since begun around the world. Gold is the top priority, but the rare earths as well as tungsten and lithium come close behind. The bionics expert Kunz turned to manganese. Manganese does not come from the mine, but from a plant pulp. It is fished out of a pulp pulp with a magnetic separator and can be used in a wide variety of products.”                                   Hab
