Recycling
In 2020, we produced about 3.2 million tons less waste. The volume of our most significant waste type, construction waste, was mainly impacted by the Stuttgart — Ulm project (–3.4 million tons) in 2020. As compared to the previous year, the volume of waste generated fell by about 30%. The recycling rate fell slightly but remains at a very high level. The volume of municipal waste also fell slightly by 7%.
