QUASAR will develop and implement solutions for a systematic collection and management methodology and decision tools for EOL-PV-modules based on a holistic approach between all parts and actors across the EOL supply chain including concepts of reverse logistic technologies, AI/machine learning, product lifecycle information management (PLIM) based on digital twins, and best practices for sorting, warehouse operations, testing and repair/reuse. EOL decision-making will be supported through the delivery of a digital product passport thanks to smart sensor tags as well as rapid, non-destructive testing methods for assessing EOL-PV condition for reuse/repair/recycling in the field and at waste treatment facilities. Repair technology solutions will be provided, along with guidelines for second-life warranty, quality thresholds, product reliability, labelling and tracking. QUASAR will upscale and demonstrate two emerging recycling technologies based on delamination by controlled thermal and chemical treatment [pilot A] and waterjet delamination [pilot B], targeting EOL-PV recycling rates of 70-90% for silicon, metals, glass and polymers with high purity for reuse in the PV industry, as well as semi-conductor industry, speciality chemicals, float glass, or other products. Material closed-loop systems will be implemented to enable a circular economy for the PV industry. By 2050, from the upscaling and worldwide deployment of both recycling technologies, substantial volumes of secondary raw materials will be unlocked: 220,000 tons of silicon, 5,200 tons of silver, 62,000 tons of copper and 4,700,000 tons of glass, accompanied with 421 million tons of CO2 savings. To achieve its specific objectives, QUASAR gathers a multidisciplinary consortium involving commercial actors from across the entire EOL supply chain: PV module manufacturers, utility scale PV system operators, collectors, recyclers, and end users of recycled secondary raw materials.
