The waste treatment and energy recovery for the world's largest rum distillery (Bacardi Corp., San Juan, Puerto Rico) uses an aerobic digestion to treat distillery wastes and to produce methane gas for use as boiler fuel. The system provides an annual estimated fuel savings of $1 million. (Projected savings were as high as $2 million per year prior to the oil glut of 1982-83.) Also wastes discharged to the ocean have been reduced and operating costs are low. The process has potential for other industries as well.
