Landfill gas project unveiled in Missouri

Jefferson City, Mo., October 19, 2009 — Missouri Gov. Jay Nixon cut the ribbon on a new renewable energy project in Jefferson City, Missouri. This renewable energy project, developed through a partnership between Republic Services, Ameresco, Columbia Water & Light, and the State of Missouri, was recently featured at the White House in a meeting hosted by Treasury Secretary Tim Geithner and Energy Secretary Steven Chu.

The project was highlighted for its contribution to creating jobs while helping expand the development of clean, renewable domestic energy.

“This project creates a clean, reliable and consistent source of energy from a naturally occurring byproduct of our landfills,” Gov. Nixon said. “I commend this innovative partnership for the benefits it will bring our economy, environment and communities.”

Republic Services, Inc. and Ameresco partnered to develop the landfill gas-to-electricity project that uses a gas byproduct from the Jefferson City Landfill.

Landfill gas, which is created when organic material naturally decomposes in a landfill, consists of about 50 percent methane. It is a readily available, reliable local alternative energy source that offsets the need for fossil fuels. The gas can be converted and used in many ways: to generate electricity, heat or steam; or as an alternative vehicle fuel.

Ameresco, an independent energy services company, designed, built, owns and operates the renewable energy project.

First, Ameresco constructed a 3-mile pipeline to carry the landfill gas from the landfill to an engine facility located at the Jefferson City Correctional Center (JCCC). The gas is used to generate 3.2 MW of electricity.

The green power, which is purchased by Columbia Water & Light, provides enough electricity to meet the needs of nearly 2,000 Columbia Water & Light customers. It also reduces green house gas emissions equivalent to planting 31,000 acres of trees and removing almost 28,000 vehicles each year from Missouri roads.

Additionally, Ameresco captures the waste heat generated from the engines to provide steam and hot water for the state-owned correctional center. Greenhouse gas emissions reductions from using the waste heat to offset natural gas in the boilers are equivalent to heating 1,500 homes, planting 1,300 acres of trees and removing almost 1,000 vehicles each year from Missouri roads.
