St. Louis Composting

St. Louis Composting

Food Waste Processing


Founded in 1992 by Patrick and Rebecca Geraty, St. Louis Composting has grown into the region's largest compost producer. Its five composting facilities process about 600,000 cubic yards/year of green material, primarily yard trimmings. The BioCycle tour takes place at St. Louis Composting's Belleville, Illinois facility, a 110-acre site. The Belleville facility is permitted to compost source separated food residuals, including materials from grocery stores, restaurants, cafeterias and other generators in the St. Louis region.


St. Louis Composting

Anheuser-Busch Brewery

Anaerobic Digestion
Of Brewery Wastewater


The Anheuser-Busch brewery in St. Louis has installed the largest high rate anaerobic system in the world, treating 2.5 million gallons/day of brewery wastewater. Tour of the Bio-Energy Recovery System (BERS) includes high rate reactors that remove 70,000 lbs/day of BOD (80 to 90% removal), saving Anheuser-Busch $21,000/day. BERS generates 800,000 cubic feet of methane daily, which is combusted in the brewery's Powerhouse and reduces overall fuel consumption by 7.5 percent.


St. Louis Composting

Missouri River WWTP, Metropolitan St. Louis Sewer District

Treatment, Utilization
Of Digester Biogas

The St. Louis Sewer District’s Missouri River Treatment Plant (MRTP) has a current design flow of 28 million gallons/day (mgd), with a peak design flow of 80 mgd. The facility is undergoing a major upgrade, including retrofits of its four anaerobic digesters. The BioCycle Conference tour focuses on MRTP's three Waukesha engines/generators, each rated at 335 kW, as well as a Unison gas conditioning system. Heat recovered from the engines is used to maintain a 98°F process temperature in the anaerobic digesters, and to heat the Administration Building in cold weather.


This all day site tour on Wednesday, October 31 includes visits to each of these three sites. All participants will board bus at the St. Louis Marriott Union Station hotel about 7:45 am, and return to the airport/hotel by about 4:30 pm. Site tour registration fee of $95 includes transportation and box lunch.
