Electric power; steam and chilled water were consumed in beer brewing process. The process is intensive in energy conversion and utilization. The brewery wastewater can generate biogas of high methane content through anaerobic sludge fermentation. This high concentrated biogas could be an excellent choice employed in energy conversion and utilization. The reclaimed water; after proper treatment; could be employed to scrub CO2 and H2S in biogas. Through compression; the purified biogas could be stored as fuel for mechanical operation and further incorporated into the municipal LNG pipe network. According to biogas yield and energy requirements in breweries; energy usage efficiency and configuration of device for biogas Integrated Energy System (IES) were investigated. This paper introduced an Otto cycle internal combustion engine using biogas for power generation. With the biogas yield of 34.84m3/h (standard state); the power efficiency of 28.45% could be generated with electricity of 70.0kW. Efficiency of combined heating and power (CHP) can reach 61.80% employing the excess heat of the engine exhaust. There are successful examples of combined cooling and power (CCP); combined cooling and heating (CCH) that has efficiency of over 60%.
