In RETRIEVE we aim to combine PV upstream value chain organizations with beyond state-of-the-art recycling processes and techniques to improve circularity within the PV sector. RETRIEVE targets the upcycling of the components of the End of Life (EoL) solar panels, enhancing the material quality to meet current requirements for re-introduction into the PV value chain. RETRIEVE will increase the circularity and minimize the environmental impact of the PV industry by developing and demonstrating cost effective recycling technologies for the different components of a solar module; recycle glass to current PV specifications, purify production waste and EoL silicon to solar grade quality, recover silver and heavy metals, and polymer valorization with carbon capture. The final goal is to demonstrate a closed-loop recycling process where recycled glass as well as silicon is re-used in state-of-the-art solar module production, turning the EoL PV panels into sources of new raw materials for the PV manufacture industry. In addition, future PV waste streams for EoL and production waste will be forecasted, and the market potential will be evaluated. By lowering the financial burden of material recovery and increasing the value after recovery, RETRIEVE makes the overall module recycling process more profitable, and the project opens new paths for commercialization. Business cases and market introduction strategies will be developed for a selection of the processes and products.

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.
