Kroger Pursues Goal of Zero Waste.
GREENSBURG, Ind. -- Kroger Co.'s K.B. Specialty Foods has broken ground on a new anaerobic wastewater treatment system at its facility here.
The company said the modification will turn food production by-products into energy and will also lead to improved air quality in the area. It expects the new system to be operational next summer.
"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.
K.B. Specialty Foods employs 270 people and produces deli salads, cake icing and refrigerated side dish products.
The current wastewater treatment system in the facility is open to the air, the company said. 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. ADI Systems, the project builder, said the new facility relies on a process called anaerobic digestion. Microorganisms transform by-products of food production into biogas.
