29 September 2010 – Pharmaceutical firm Roche Diagnostics is to build an anaerobic plant for the biological pre-treatment of a partial wastewater flow at its Penzberg site in Upper Bavaria, Germany.
The plant, which produces energy-rich biogas, will supplement an existing membrane bioreactor system.
The biogas will be used in a CHP plant in the Penzberg site boiler house. The amount of electricity gained will cover more than 90% of the energy requirements of the wastewater treatment plant, and the thermal energy will be used to pre-heat the boiler feedwater of the power station.
Carbon dioxide emissions are expected to be reduced by around 950 tonnes per year.
The new anaerobic plant will be built by Aquantis, a subsidiary of Veolia Water Solutions & Technologies.
Assembly of the anaerobic plant is planned for March 2011 and start-up in November 2011.
