Regional rotor blade waste quantification in Germany until 2040

Worldwide, wind turbine stocks are ageing and questions of reuse recycling particularly rotor blades become urgent. Especially, rising blade wastes face lacking good options exact quantification is difficult due to information gaps on the size, mass material composition. In a combined approach, expected waste quantified localized national level for Germany until 2040. Fibre-reinforced plastics (FRP) from in focus differentiated into two classes: glass-fibre reinforced (GFRP) glass- carbon-fibre (GFRP/CFRP). The approach based power plant stock database (Marktstammdatenregister) regression models, with class-based estimation missing datasets. As result, between 325,726 429,525 t GFRP class 76,927 211,721 GFRP/CFRP arise obsolete This corresponds share 11% 32% turbines Germany. For GFRP, peaks 2021, 2035 2037 around 40,000 per year. GFRP/CFRP, 2036 will induce more than 20,000 t/a. Mostly affected federal states Lower Saxony, Brandenburg, North Rhine-Westphalia Schleswig-Holstein. methods applicable transferable other countries, fleets.
