Sustainable waste management in Quarzbichl

Since 2014, electricity and heat have been generated from biogas using a combined heat and power plant (CHP) on the WGV Quarzbichl site. The latter is consumed directly and the electricity is fed into the grid.

Around 23,000 tonnes of organic waste from the Bad Tölz-Wolfratshausen and Weilheim-Schongau districts, as well as a portion from the city of Munich, are processed here.

Another avus 500b CHP plant from 2G has now been put into operation. The reasons for investing in a second CHP plant were failure protection during repairs to the existing cogeneration plant and the possibility of fully utilising the peaks in gas production, which occur particularly in winter, for electricity generation.

The cogeneration plants have an output of 800 and 637 kilowatts. They generate at least 6.00 gigawatt hours of electricity (in 2021 it was 6.15 gigawatt hours) and 6.30 gigawatt hours of heat every year. Around 1.75 gigawatt hours of the electricity generated covers the needs of all plant areas in Quarzbichl, including administration. The remaining larger part is fed into the electricity grid, so that around 1,400 households can be supplied with renewable electricity.
