📌IREC - Institut de Recerca en Energia de Catalunya researchers and partners of the SUNRISE Project have designed and tested a multisensor sorting tool for smart #recycling of PVB interlayer in #laminated #glass #waste. Laminated glass is obtained by bonding glass layers using a polymeric interlayer and Polyvinyl Butyral (PVB) as one of the widest used materials for this application. In the EU, the laminated glass waste, only from the renovation and demolition sectors, achieves more than 1.5 million of tons per year, which accounts ~0.9 million of tons of landfilled waste every year. A significant part of this waste consists of the interlayer PVB material, and up until now, only 9 % of all post-consumed PVB is recycled. The efficient recycling of PVB faces several difficulties related to the unknow compositions and optical degradation level of the of interlayer polymers. In this direction, the main goal of the SUNRISE project was to develop an innovative optical multisensor sorting tool using #spectroscopic techniques and #AIalgorithms that allowed optimal on-line classification of laminated glass waste with respect to composition and degradation level of PVB interlayer. The Solar Energy Materials and Systems (SEMS) Department, at IREC - Institut de Recerca en Energia de Catalunya, was one of the leading partners in achieving this goal by developing methodologies and sensors that facilitated the evaluation of the degradation level and chemical composition of the PVB interlayers inside the laminated glass waste. IREC, in collaboration with Lenz Instruments, S.L., has implemented, installed and validated the multisensor sorting tools in two demo sites: i) in pilot line for recycling of laminated glasses in Centro Tecnológico Lurederra (Spain); ii) in recycling plant of the DISMECO SRL company (Italy). The SUNRISE consortium is formed by 20 European partners including L'urederra (project coordinator), and researchers from the SEMS Department at IREC, led by Dr. Maxim Guc together with Dr. Victor Izquierdo Roca, and the engineers Rafael Mayer and Fernando Miranda Bardales.
