Landfill gas ranks Coca-Cola third in EPA green power users

The U.S. EPA released its top 25 onsite green power generators through its Green Power Partnership program for this quarter, and Coca-Cola has ranked third, mainly because of a 6.5 MW combined-heat-and-power (CHP) system the company commissioned in April.

The facility was developed by and is owned and operated by Mas Energy. Located at Republic Services’ Hickory Ridge landfill in Atlanta, Ga., it’s located adjacent to Coca-Cola’s syrup plant and supplies it with all of its electricity, steam and chilled water needs.

Methane collected at the plant is cleaned, upgraded and delivered to the CHP plant via a six-mile pipeline owned by Atlanta Gas Light. There, three GE reciprocating engines convert the gas into power, and three Kickham heat-recovery engines use heat from the GE engines to produce steam. A York steam turbine-driven chiller then uses that steam to produce chilled water.

Development of the plant, which is one of the largest landfill gas-to-energy systems in the country, required collaboration with many partners in order to acquire the landfill gas rights, secure financing, negotiate agreements and oversee all permitting, regulatory compliance, design, construction and operations, according to Mas Energy. These partners include Atlanta Gas Light, GE, Veolia Energy North America and EIV Capital Management.

Coca-Cola now uses six percent renewable energy as a company, according to the EPA rankings, more percentagewise than the top two green power users.
