Beer comes clean [beer manufacturing]

Abstract

There's little more summery than a cool pint of ale or a cold lager. New technology in brewing ensures that it doesn't come at the expense of the environment, says Bryan Betts. Like most industries, brewing has come under pressure to improve its sustainability and, in particular, its use of water; energy and transportation. Brewers of all sizes have responded by turning to technologies both old and new, as they re-engineer their processes to save cost and cut wastage. [ABSTRACT FROM AUTHOR]
