Opportunities and barriers for efficient energy use in a medium-sized brewery

Carbon footprint of a pale lager packed in different formats: assessment and sensitivity analysis based on transparent data

“…(4.56 L L À1 ) and InBev (4.32 L L À1 ) (Miller S.A.B., 2011). Actually, water consumption for modern breweries varies from 3.5 to 10 L L À1 of beer produced, but in old microbreweries it can be as high as 19 L L À1 (Sturm et al, 2013). The recovery of spent yeast as a feeding supplement appeared to be less than that usually registered, probably because of its re-use as production yeast for at least 4 fermentation cycles.…”

“…Table 11 summarizes the main material, water, and energy consumption yields, as well as waste production ones, relative to the operation of the Birra Peroni Srl brewery, as compared to the typical and average (within brackets) ones for some European breweries (Donoghue et al, 2012;IFC, 2007;Olajire, 2012;Sturm et al, 2013;UNEP, 1996).…”

Bioenergy from stillage anaerobic digestion to enhance the energy balance ratio of ethanol production

“…As an example, the energy consumption in the ethanol industry is significantly higher (>500%) compared to brewing industries (Sorrell et al, 2000;Galitsky et al, 2003;Scheller et al, 2008;Olajire, 2012;Sturm et al, 2012), which also generates wastewaters containing high fractions of organic matters readily convertible in anaerobic processes. Wastewaters from piggery, dairy, slaughterhouses, food processing and especially other biofuel industries, such as biodiesel, should also be included.…”

Adsorption thermal energy storage for cogeneration in industrial batch processes: Experiment, dynamic modeling and system analysis

“…As representative example for an industrial batch process, we consider breweries. In particular, small and medium sized breweries have large potential to improve their energy efficiency [12]. Sturm et al [13] show that cogeneration can be profitably applied to meet the brewing process energy demand.…”
