Resource and Energy Efficiency in Small and Medium Breweries

Anaerobic Digestion of Pretreated Industrial Residues and Their Energetic Process Integration

“…Table 3 shows the calculation of the energy potential in the two main residual streams. Data from Muster-Slawitsch et al (2011) and Kubule et al (2016) clearly demonstrate that the implementation of anaerobe technology for residue degradation is technologically and economically feasible. Kubule et al (2016) presented several breweries and their energy requirement during brewing operations.…”

“…Data from Muster-Slawitsch et al (2011) and Kubule et al (2016) clearly demonstrate that the implementation of anaerobe technology for residue degradation is technologically and economically feasible. Kubule et al (2016) presented several breweries and their energy requirement during brewing operations. In order to allow energy recovery by AD integration, breweries require an energy efficiency analysis and have to establish activities to reduce the specific energy demand during the brewing process (Muster-Slawitsch et al, 2011;Kubule et al, 2016).…”

“…Muster-Slawitsch et al 2011identified an average breweries' energy demand with about 37 MJ hl −1 beer (Muster-Slawitsch et al, 2011). Compared to the Austrian example of Gösser Brewery presented by Muster-Slawitsch et al 2011, some other closely monitored and evaluated breweries have an up to 4 times higher energy demand during the brewing process (Kubule et al, 2016). Thus, the potential for energy recovery in many breweries is huge.…”

If breweries increase their energy efficiency, anaerobic treatment of BSG and wastewater treatment to produce biogas is an alternative to enable the switch to a fossil-fuel-free brewing industry.…”

Ecoeficiência em cervejarias artesanais: um estudo de casos múltiplos

“…Em relação ao consumo de energia elétrica, cervejarias europeias otimizadas, que produzem em larga escala, utilizam cerca de 0,10 a 0,12 kWh por litro de cerveja produzida (European Commission, 2006), enquanto as pequenas cervejarias (produção de 125 mil litros por mês) consomem cerca de 0,22 a 0,26 kWh por litro (Kubule, Zogla, & Rosa, 2016). No contexto das artesanais brasileiras, apresentam consumo mais elevado, de 1,06 kWh/l (Ortiz, 2014).…”
