Maker's Mark Fuels Operations with Bourbon Waste
By GreenBiz Staff

LORETTO, Ky. -- Marker's Mark has turned on a new treatment system at its Loretto, Ky., distillery, turning waste into energy for the facility.

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 percent of the distillery's natural gas use.
