Reflows – Circular bio-based products from protein rich brewery waste streams

The project’s aim is to create a value network for valorisation of spent yeast residual streams. Furthermore, the project pursues developing process logistics, material properties and applications in two different market segments. The focus is on bio-based raw materials that can be extracted and used in industrial processes. The consortium will design new value cycles so that today’s waste streams are handled efficiently to produce new raw materials.
