5 Overview 5

6 Perfect fit for brew industry 1. Brewery Process 6

7 7 2. Raw Materials Raw Materials of the Brewery Process Malt Hops Yeast Water Filter aid Diatomite

8 8 3. Products Products and by products of the brewing process Beer Spent Grains ~ 20 kg/hl brewed beer Surplus Yeast ~ 1,5 kg/hl brewed beer Filtration Sludge ~ 0,9 kg/hl brewed beer Waste Water* * The amount of waste water depends on the rate of internal recirculation of waste water

9 9 4. By - Products green energy potential Spent Grain TS ~ 18-28%, VS ~ 95% of TS TKN ~ 8 kg/t Methane Yield ~ 435 Nm³ CH 4 per t VS, ~ 50 days to > 99% Surplus Yeast TS ~ 15%, VS ~ 95% of TS TKN ~ 12 kg/t Methane Yield ~ 444 Nm³ CH 4 per t VS, ~ 30 days to > 99%

10 10 5. Brewery example Production of hl produced beer specific energy demand of ~ 15 kwh per hectoliter energy production out of by-products ~ 15 Mio kwh biogas out of by-products can substitute up to 100% of the energy demand of a brewery Digestate high quality digestate due to high quality raw materials high rate on nitrogen, phosphorus and potassium in process for the certification as a bio-fertilizer (high value)

11 Challenges 11

12 12 1. Fluctuation Seasonal fluctuation the brew amount varies from month to month high rates in summer, middle rates in winter and low rates in fall and spring Weekly fluctuation brewing days per week varies from brewery to brewery high rates of gas demand on only a few days per week possibility that on weekend no gas is needed

13 13 2. Feed vs. Fuel Spent Grain is rich in protein often used as cattle feed goes off very fast, specially in summer (~ 2 days) demand of farmers depends on the weather conditions and the quality of grass harvest to get rid of the spent grains, breweries depend on farmers this results in price fluctuations

14 Example Göss (Heineken Group) 14

15 15 1. Motivation Getting the first big brewery which is 100% green Getting independent from energy prices Getting independent from farmers They already reduced their natural gas consumption by ~ 50% using waste heat of the saw mill m² solar field producing biogas out of the waste water (UASB reactor) technical and organizational changes

16 2. Status Quo 16
