Environmental protection in the brewery.

Heyse, K.-U., Hiller, N. and Beer, R.

Abstract
Guidelines for the evaluation of the environmental impact of a brewery and the minimization of water and energy consumption and waste production are presented. Topics discussed include the specific inputs of raw materials, processing aids, water, energy, etc., into the different stages of the brewing process (wort production, fermentation/maturation, filtration, packaging) and the solid wastes, effluents and gas/vapour emissions from these process stages, the useful by-products which are generated by the brewing process or can be obtained from its wastes, measures to reduce energy consumption and recover waste heat, the advantages and disadvantages of different effluent treatment systems and the cost savings that can be achieved through some environmental protection measures.
