Maker's Mark fuels operations with bourbon waste
Marker's Mark has turned on a new treatment system at its distillery here, turning waste into energy for the facility.
Loretto, KY – Marker's Mark has turned on a new treatment system at its distillery here, turning waste into energy for the facility, according to a news item posted on Greenbiz.com .
The anaerobic digestion facility installed by waste management provider Ecovation will process stillage—the water, grain and yeast waste leftover from making bourbon—and produce a methane and carbon
dioxide biogas for use in the distillery's boilers.
The stillage treatment, which was incorporated into the facility's existing wastewater treatment system, is expected to offset 15-30% of the distillery's natural gas use.
The $8 million system is estimated to produce 85 million BTUs a day, and will eventually produce up to 165 million BTUs a day as the distillery increases its production of bourbon from 840,000 cases to 2.2 million cases a year over the next 10 years.
Anaerobic digestion is a process in which organic materials are broken down by microorganisms. Previous to using the system, Maker's Mark would dry and ship its stillage to farmers for use as cattle feed.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
