Cincinnati-based The Kroger Co. (NYSE: KR) says a new wastewater treatment system at its subsidiary's manufacturing facility in Greensburg is operational. The $9.5 million anaerobic digester at the K.B. Specialty Foods plant converts organic materials into renewable biogas.

It is the second anaerobic digester for Kroger, the first of which is at the company's Ralphs-Food 4 Less distribution center in California. The system features a dome that captures biogas from food byproducts at the plant and converts into energy.

"We invested in the digester because it improves our sustainability performance, supports better air quality and provides a cost savings to the company," said Erin Sharp, group vice president of manufacturing for Kroger. "Once the digester is operating at its optimal level, we project it will have the capability to produce nearly 30 percent of the plant’s electricity."

Kroger broke ground on the project in November 2016.

The investment is part of the company's "Zero Hunger | Zero Waste" initiative, which aims to eliminate waste within the company by 2025. Kroger says the K.B. Specialty Foods plant has been a zero waste facility since 2014.

Many can be chalked up to carelessness, insensitivity and lack of relevance or connection. Most organizations could benefit from a communications audit.
