In Poland, in 2023, renewable energy sources, such as wind turbines, solar photovoltaic panels, accounted for over 40%. installed capacity in the Polish energy mix and accounted for 27%. total energy production. Thus, Poland broke further European records in the increase in the share of renewable energy. The goals we set for ourselves are over 50%. green energy in 2030, and in 2050 we will have to reach 100%. the service life of installations of renewable energy sources: photovoltaics, wind turbines is estimated at 25-30 years[1,2]. After this time, the installation will be recycled. The article presents waste-free technologies for recycling photovoltaic panels and windmill blades developed by a consortium of universities (AGH University of Kraków) and 2LOOP TECH [3,4]. The developed technologies meet the assumptions of a closed-loop economy (circlar economy). The article presents a life cycle analysis (LCA) of PV panels and wind blades. The implementation of technology in industrial conditions implements the principle of “secondary first”.
