Kroger converting food waste to bioenergy

Supermarket giant Kroger has teamed with FEED Source Recovery to convert waste food into electricity on a mass scale.

The anaerobic conversion system (PDF) will process more than 55,000 tons of organic food waste into renewable energy annually and provide power for the over 650,000 square foot distribution center. By diverting that food waste – the equivalent of 150 tons per day – the system will also reduce area truck trips by more than 500,000 miles each year. The Kroger Recovery System uses a sophisticated process to convert the carbon in organic material into a renewable source of methane.
