IRIS GLEN LANDFILL GAS TO ENERGY FACILITY
Johnson City, TennesseeEnergy Systems Group designed, engineered, installed and funded the innovative Iris Glen Landfill Gas to Energy Facility in Johnson City, Tennessee. ESG also continues to operate and maintain the facility. Processed landfill is transported through a four (4) mile, dedicated pipeline built and operated by ESG to the Mountain Home, Veterans Administration (VA) Hospital. This project serves two main clients and over 2,000,000 square feet of facilities with waste to energy gas.
This project is being funded entirely by ESG with no cost or debt to the City of Johnson City, TN. The anticipated annual revenue to the city is approximately $500,000+ per year and this amount will grow over the life of the project.
The gas is used as a one-for-one replacement of natural gas which is used to generate steam, electricity, and chilled water for the VA complex.

ENERGY SYSTEMS GROUP (ESG) EXEMPLIFIES COMMITMENT TO LANDFILL GAS UTILIZATION ESG WINS SWANA’S 2007 EXCELLENCE AWARD
Evansville, Indiana (October 2007) – Dr. John Skinner, Executive Director and CEO of SWANA, the Solid Waste Association of North America, is pleased to announce that Energy Systems Group (ESG) was awarded SWANA’s Bronze Excellence in Solid Waste Management Award in Landfill Gas Utilization. The award will be publicly presented at WASTECON, SWANA’s annual solid waste exposition, on Thursday, October 18, 2007 in Reno, Nevada.
Energy Systems Group was presented SWANA’s Excellence Award for the success of their Landfill Gas Utilization program at the Iris Glen Landfill Gas to Energy Facility in Johnson City, TN. An innovative collaboration between the City of Johnson City, TN and Energy Systems Group, the landfill project employs inventive use of landfill gas that conserves natural resources, reduces greenhouse gases, and provides a long-term revenue source for the City of Johnson City.
One of the first of its type, the Iris Glen Landfill project employs an innovative membrane filtration system; ESG engineered and built the landfill gas processing system to convert raw low BTU gas to clean high BTU gas as a direct replacement for natural gas. ESG constructed a four-mile pipeline through the city to the Mountain Home Veterans Administration Medical Center where the renewable gas is used to generate electricity and steam.
The Iris Glen Landfill Gas to Energy Facility eliminates the equivalent amount of emissions as would be saved by removing 34,000 cars from the road, or planting 49,000 acres of trees, or heating over 11,000 homes.
“SWANA is pleased to honor Energy Systems Group for the outstanding accomplishments they have achieved over the past year. Their commitment to advancing solid waste management is resulting in a cleaner environment and improved public health. We are very proud of their efforts.” said Skinner.
“We are extremely proud of this investment and pleased to deliver all the benefits of such an environmentally responsible project,” commented Jim Adams, President of Energy Systems Group. “ESG continually develops innovative projects that promote energy conservation while providing significant financial benefits to the communities we serve.”
SWANA’s Excellence Awards Program recognizes outstanding solid waste programs and facilities that promote socially, environmentally and economically sound management of solid waste. Award winners demonstrate their commitment to environmental regulation compliance, program efficiency, safety and progress.
