Abstract:
Biopolymers are biodegradable without residue and are produced without the addition of chemical substances such as plasticizers, stabilizers, etc. They could be consumed by humans and animals without this leading to health effects. They do not release any hazardous substances into the environment during the decomposition process and this product can be biodegraded within a few weeks. Basically, this material can even be used as fertilizer in agriculture after use. This would also have great advantages for the recycling process. Complex recovery of raw material with high material and energy loss is no longer necessary. Packaging can be composted and does not have to be. In addition, no valuable resources are wasted. The raw material for production is a waste product from the food industry. After the first processing and use, it gets a new purpose and can be used a second time. If the composting of the bioplastic is included, a raw material has been used three times before it is returned to the natural cycle as fertiliser. Thus, the natural cycle closes again and no residues remain. It is a novel process for producing bioplastics. Waste food industry, e.g. from beer production, is a specially coordinated process. After the fermentation process, extracted plant substances are added and processed into a homogeneous mass. This is heated to a suitable temperature and then dried and pressed into granule form. These granules can then be used in a wide variety of manufacturing processes for packaging materials, etc. The plastic that is created is resistant and water-soluble. It can be used in the food industry or in the cosmetics industry as a packaging material.
