It's Conference Time Again
The International Biomass Conference & Expo is coming up quickly, so I hope all of you are registered and have your hotel reservations.
I haven’t been to a conference since the Pacific West Biomass Conference & Trade Show that was held in Seattle in January, so I’m ready for a week of biomass immersion.
The conference kicks off May 2 with the biomass facility tours, including the Anheuser-Busch Bio-Energy Recovery System, Innovative Energy Inc. and IESI MO Champ Landfill.
Adding value to waste streams is not a new activity for Anheuser-Busch. Its Bio-Energy Recovery System uses anaerobic digestion to capture energy from wastewater and was first installed in 1985 at its Old Bridge, N.J., baker’s yeast plant, according to the company. “The first brewery application was in upstate New York in 1991, primarily to dampen out the loading swings that our aerobic system saw and allow us to reduce the electricity demand to fully treat the wastewater,” said a company spokesman. “The reduced fossil fuel cost was just a secondary benefit at the time, but over the past five to 10 years has greatly increased in value. In facilities where discharge is treated by a municipal system, we also see savings from the increased consistency of our discharge and the reduced electricity requirements to treat it.”
Anheuser-Busch is working to expand its BERS to include anaerobic solids digestion of the yeast, grain and other protein that is in the brewery wastewater to increase biogas production and system stability.
The company also uses brewery residuals as liquid fertilizer to grow forage and energy crops and solids from its wastewater treatment process are stabilized, dewatered and used for land reclamation to grow willow trees, which can be used for fuel.
