A couple interesting articles about sustainability efforts in the brewing industry were recently posted on the news website of the UW-Madison’s Department of Engineering Professional Development. The first by Meg Turville-Heitz focuses primarily on the big multinationals. For example,
“Sustainability is a concept of rapidly increasing importance in the brewing industry,” says Ryan Griffin, a sustainability advisor with See the Forest, LLC, and a former asset management engineer at MillerCoors, which remains a client. As a student in the Master of Engineering in Sustainable Systems Engineering (SSE) program at the University of Wisconsin-Madison he has worked to spread ideas learned from a systems perspective to the organization. “One such idea is using the concept of industrial ecology to analyze resource use throughout our supply chain,” says Griffin. “We are now beginning to build long-term partnerships with our material suppliers to design sustainability into how we operate. This could mean helping barley farmers grow their grain with less water, or our packaging suppliers use less energy to produce their materials.”
He notes that water and energy efficiency per barrel of beer brewed “are two metrics the company has actively worked to improve for the last five years. Two MillerCoors breweries are already at world class levels of water consumption per barrel” or less than a ratio of 3:1 water use to beer, and “others are close behind,” he says. Additionally, six of the company’s eight breweries have achieved goals of zero waste to landfills.
New Glarus Brewing Company in southwest Wisconsin has been experiencing double digit growth, averaging 18% every year since it opened in its initial Riverside Brewery in 1993, says founder and president Deb Carey. “We’ve just completed $9 million in expansion and another $11 million on the way,” she says, adding “We doubled the capacity of our Hilltop brewery from 150,000 to 250,000 barrels per year.”
Those expansions have been a model in sustainability. “It’s been about reclaiming steam, heat exchangers, reclaiming chemicals, our own sewage treatment plant, wind and solar,” says Carey. For example, the chemicals used to rinse the three miles of pipe in the facility are re-used in washing down floors, and treated wastewater drawn from their own treatment plant – reducing the brewery’s impact on the community sewage treatment system – has been used in irrigation on the grounds.
