A team of researchers from the Centre for Biomedical Technology at Universidad Politécnica de Madrid (CTB-UPM) is working with the Instituto de Ciencia de Materiales de Madrid (ICMM-CSIC) and the Institute of Catalysis and Petrochemistry (ICP-CSIC), from the Spanish Council for Scientific Research (CSIC), to use waste from the agri-food industry (apple pomace from juice production, to be precise) to make biomaterials for regenerating bone and cartilage tissues. The biomaterials act as 3D matrices for tissue regeneration, which are useful for aging-related diseases that require regenerative medicine, like arthritis, osteoporosis, or osteoarthritis. According to the team's published research paper, this is the first report of materials derived from apple waste to be used in hard and soft tissue engineering applications.
