Kroger’s KB Specialty Foods Plant Uses Biogas Technology to Create Energy

Kroger Co.’s (NYSE: KR) KB Specialty Foods’ new anaerobic wastewater treatment system at their facility in Greensburg, Indiana is now fully operational. The state-of-the-art waste water treatment facility was designed, built, and installed by ADI Systems North America, an Evoqua Company. Universal Blower Pac, INOHVA’s sister company, engineered and manufactured the biogas blower system and hybrid blower systems for the sequencing batch reactor.


While the previous wastewater treatment system in the facility was open to the air, the new system features a dome to capture biogas from food byproducts at the plant. “This is one more step toward meeting our goal of becoming a zero waste company by 2020,” said Suzanne Lindsay –Walker, Kroger’s director of sustainability.  (Source: Kroger Co, 2016 PR Newswire)



In this video of the biogas system overview, ADI Systems Process Engineer, Daniel Bertoldo, demonstrates how the new facility relies on a process called anaerobic digestion.  Microorganisms transform the byproducts of food production into biogas, and that biogas is extracted and scrubbed for a source of renewable energy.  The electricity created is sent to the plant’s electrical grid.


KB Specialty Foods Plant Engineer Eric Behn said this investment “represents KB Specialty Foods’ continued commitment to both the Greensburg community and energy sustainability.”


The new system is expected to reduce unpleasant odors in the area with fully covered tanks to hold untreated water. In addition, approximately 40 percent of the plant’s electrical needs will be produced with byproducts of the treatment process via a combined heat and power generator. The new facility will also provide increased treatment capacity for KB Foods. (Source: Greensburg Daily News, Oct 14 2016)
