Holistic concept for water and recyclables recovery for the food industry in breweries – Part II
In part I of this contribution (BRAUWELT International no. 5 2011, pp. 290-292), possible strategies for therecovery of water and recyclables in breweries were summarized. As a sequel, part II deals with effluent end-of-pipe treatment and elaborates on the solution that may ultimately prove to be the best for an existing brewery, taking account of considerations having a bearing on industrial water recovery. Solid recyclables, such as beer spent grains or yeasts, also have a high material and energy potential. Therefore, possibilities of recycling same are discussed, leaving aside agricultural use. This will become part of a future holistic concept.
