KB Specialty Foods, the food production business owned by US retailer Kroger, revealed it is investing in an anaerobic waste water treatment system at its facility in Greensburg, Indiana.
The current waste water treatment system in the Greensburg facility is open to the air. The new system will feature a dome that will capture biogas from food by-products at the plant. The collected biogas will then be harnessed to generate electricity via a process called anaerobic digestion. The electricity will then be sent to the plant’s electrical grid.

KB Specialty Foods expects the new system to be operational next summer.
Kroger said that the investment is part of its drive to become a zero-waste company in four years time.
“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.
KB Specialty Foods employs 270 and produces deli salads, cake icing, and refrigerated side dish products.
