ABSTRACT

In the process of brewing and packaging beer, many secondary streams are produced that are not part of the beer product stream, and they cannot be used in the final product. Around the world, large breweries and small craft breweries alike have adopted sustainability programs. This chapter examines the different areas of brewery operations and how they affect the profits, people, and the planet in terms of effluents, emissions, and energy usage. Emissions and effluents are described along with various treatment options. Progress in reducing energy usage and beer losses throughout the process is also reviewed. Receiving and conveying grains and other raw materials into the brewery can be a source of dust emissions into the atmosphere. The brewhouse generates liquid waste streams produced during lautering or mash filtration, from processes that separate hops and trub in hot wort after boiling, and cleaning-in-place (CIP) rinses and cleaning solution discharges.
