DESCRIPTION:Zupancic\, Gregor (National Institute of Chemistry\, SL)\nBrew
 ing industry is a large consumer of natural gas\, a middle size brewery of
  annual 100\,000 m3 of brew production can consume as much as 4-5 million 
 m3 of natural gas per year. To achieve and surpass the EU renewable energy
  goals of 20% by 2020\, we have examined the possibilities of biogas produ
 ction from brewery waste. Biogas is an excellent renewable energy resource
  and can easily replace natural gas. There are three main available waste 
 groups\; firstly brewery wastewater. Biogas from wastewater using well est
 ablished conventional anaerobic technology can substitute up to 10% of nat
 ural gas. The second source is fermentation residues\, mostly waste brewer
 y yeast. This can contribute an additional 6 %\, using adaptations to the 
 wastewater treatment technology. Third\, the largest source of waste are s
 pent brewery grains. The biogas potential of spent brewery grains can repl
 ace an additional 40 % of natural gas. Resolving the difficulties in anaer
 obic digestion of spent brewery grains (e.g. slow degradability\, high N:C
  ratio\, phenolic inhibition) would easily meet and surpass the required r
 enewable energy goals.  Our ongoing research has shown that such brewery w
 aste treatment and energy production can be environmentally sustainable an
 d can bring economic benefits as well.
