Seven Fraunhofer Institutes are pooling their expertise in the lighthouse project Waste4Future to develop new solutions for adjustments in the value chains, from the raw material base to material flows and process engineering right to the end of a product's life cycle. In particular, they want to increase energy and resource efficiency in the use of plastics and thus pave the way for a chemical industry that requires fewer fossil raw materials and produces fewer emissions.
The Waste4Future beacon project aims to create new opportunities for recycling plastics in order to make the carbon they contain available as a "green" resource for the chemical industry. The outcome of the project, which will run until the end of 2023, is expected to be innovative recycling technologies for complex waste that can be used to obtain high-quality recyclates.
Specifically, the development of a holistic, entropy-based assessment model is planned, which will reorganize the recycling chain from process-guided to material-guided. A new type of sorting identifies which materials and in particular which plastic fractions are contained in the waste. Based on this analysis, the total stream is separated and a targeted decision is then made for the resulting sub-streams as to which recycling route is the most technically, ecologically utilized by means of mechanical recycling is available for chemical recycling, always with the aim of preserving the maximum possible amount of carbon compounds. Burning waste containing plastics at the end of the chain is thus eliminated.
For the development of the corresponding solutions, the participating institutes are in close exchange with companies from the chemical industry and plastics processing, waste management, recycling plant construction and recycling plant operation, in order to consider the needs of industry in a targeted manner and thus increase the chances of rapid application of the results achieved.
