Towards a more sustainable circular bioeconomy. Innovative approaches to rice residue valorization: The RiceRes case study

The paper reports an overview of the RiceRes project aiming at the multivalorization of all the wastes of the rice value chain, namely straw, husk and bran in order to improve resources eco-efficiency. A wide range of bio-products and bio-materials with different added value has been produced starting from these wastes in the framework of the RiceRes project. Among them, insulating materials for green building have been obtained from rice straw mixed with waste wool, biofillers from husk for polymer composites, mono- and di-glyceride mixtures and high-added value molecules for the food industry from bran.
