Our way to the green brewery began in 2006 … First commitment Der Weg zur GRÜNEN-BRAUEREI

Vision 2006

In Words : –We want to cover our energy - demand from renewable energy sources and have no natural gas consumption. Der Weg zur GRÜNEN-BRAUEREI

Why ? –No greenhouse gas emissions from CO 2 –An important step towards sustainability Der Weg zur GRÜNEN-BRAUEREI

The Green Brewery is a valuable contribution for a better future Der Weg zur GRÜNEN-BRAUEREI

It began with small steps… Der Weg zur GRÜNEN-BRAUEREI

Anaerobic wast water plant with biogas Production Der Weg zur GRÜNEN-BRAUEREI

Utilisation of biogas from breweries ‘ waste water ; subtitutes 10% of our natural gas consumption Der Weg zur GRÜNEN-BRAUEREI

Spent Grain Burning –Own patent 20% natural gas reduction Der Weg zur GRÜNEN-BRAUEREI

The first Step together with Partners from Industry Feasibility studies in 3 breweries Calculation models for the brewing industry Der Weg zur GRÜNEN-BRAUEREI

Starts to support our ambitions Der Weg zur GRÜNEN-BRAUEREI

Check how brewing residuals can cover the energy - demand of Göss Comparison of technologies Mass - Balances Concepts for decision - making Der Weg zur GRÜNEN-BRAUEREI

Biofermenation of spent grains, Yeast and Kieselguhr delivers enough biogas Gas - surplus for cogeneration of green electricity Greenfield preferably Der Weg zur GRÜNEN-BRAUEREI

Solarthermal energy –Integration of solar - thermal energy in Brewery –EU - Project with Heineken – 3 Sites Göss, Valencia, Vialonga 5 % reduction of natural gas Der Weg zur GRÜNEN-BRAUEREI

1.470 m² flat plate collector / KW 200 m³ solar energy storage Plate heat exchanger for mash tun Plate heat exchanger for boiler - feedwater Investment 1.270,- k € Subsidies 50 % Fuel savings Nm³ or 150 tons CO 2

Der Weg zur GRÜNEN-BRAUEREI

Minus 50% natural gas Target is zero natural gas We are close to our target Der Weg zur GRÜNEN-BRAUEREI

Biogas through fermentation of spent grains, Yeast and Kieselguhr Der Weg zur GRÜNEN-BRAUEREI

–Biogas for covering gas - demand of brewery –Biogas for green electricity –Digestate is natural fertlilizer for the agriculture –BAT / Industrial Standards Der Weg zur GRÜNEN-BRAUEREI

Our Partner – BIO ENERGY International –Technology provider with global references –A detailed concept is finished - DBO –Official approvals relatively simple to get –Neighbours and farmers were critical Der Weg zur GRÜNEN-BRAUEREI

Input of the substrate : t / a ( t spent grain, t yeast, 900 t filter cake ) Combined heat and power – use of electricity for the production as well the heat Remaining biogas for the gas boiler to produce steam

Der Weg zur GRÜNEN-BRAUEREI

Cattle Food –Open System –Energy is not used completely –Much Truck - Traffic

Der Weg zur GRÜNEN-BRAUEREI –Zero CO 2 Emissions Bio-methan –By - product is Fertiliz er

–Independent from external energy - supply –Surplus bio - methan via Cogeneration in green Electricty to grid –Predictable energy - costs –Expect and receive positive Image Der Weg zur GRÜNEN-BRAUEREI

–Göss avoids the emission of 3000 tons of climate - relevant CO 2. –This is equivalent to one - Family - Houses –A valuable contribution for a better Future ! Der Weg zur GRÜNEN-BRAUEREI
