Brewery combines wind, solar and biogas

Between biogas, wind and solar, Anheuser-Busch generates about half of its electricity from renewable energy to make beer at its Fairfield, California plant.

The company is the largest in the US to use nutrients in its wastewater to make biogas, a process called bio-energy recovery systems (BERS).

They also recover the steam that heats boilers in the brew house to produce energy, in addition to retrofitting with more efficient boiler burners, air compressors and lighting systems.

They get another 4% of electricity from 6,500 solar panels that cover 6.5 acres. (more…)

Agricultural Waste to Biogas Plant to Keep Swiss Army Warm

Construction work has begun on a biogas plant in Bure, Switzerland that will provide heat for the local training barracks of the Swiss Army. The plant will use agricultural waste.

The plant is located in the French speaking Swiss Canton of Jura, which the company said boasts fertile soil and a lot of agriculture, and will be used to treat manure from the surrounding agricultural establishments and agro-industrial waste from the region, including liquid manure, dung, green waste, and grain waste.

The Bio Etique Energie facility will produce 370 kW of electrical output, while its entire heat surplus of 2.6 GWh will be used to heat the nearby barracks, which hosts up to 1400 trainees. (more…)
