Converting biological waste into resources is one of the keys of the circular economy, and the main objective of the European WaysTUP! Project, financed by the Horizon H2020 programme, is working on different lines of research to establish new value chains for the use of urban biowaste. Within the framework of this project, AIMPLAS, the Plastics Technology Centre, has produced a plastic film from used coffee grounds, thus transforming waste into a source of high-value products.
