The process of brewing beer dates back to prehistory – long before the advent of mass production and corporate sustainability initiatives.
Nowadays, brewers are compelled to be environmentally responsible, and are inventing ways to transform spent grains into clean energy.
The Associated Press today published a report examining how different breweries are recovering energy that was previously wasted during and after the brewing process. Here’s an overview of its findings.
I came across some additional examples after a quick Web search, including the installation of biomass heat and power plants to make Scottish and Newcastle’s UK breweries energy self-sufficient. As well as a proposal to exploit the energy potential of brewers’ spent grains in Nigeria.
Could beer brewers set an example for sustainable industry? There's only one way to find out. Prost!
