RURU processes 100% of the raw material wood, which results that even the bark is used in the form of thermal and electrical energy.

From the early 1980’s, the company Donausäge Rumplmayr has been a pioneer in operating biomass power plants that convert bark into energy. In 2006, a cogeneration unit with an electricity output of up to 7.12 MW was installed. This in-house energy production does not merely unburden the power grid; it also generates 42,000 MWh of green energy each year. This means that RURU can cover the annual energy requirement of over 10,000 households.

The production of electric power generates residual heat of 80,000 MWh, which covers the industrial process heat requirement of the entire operation. (lumber and sawdust drying)
