About the Project

The L.P. Gill Landfill Gas Recovery Project captures methane gas from the L.P. Gill Landfill and pipes it to a nearby ethanol plant. The methane is destroyed in a thermal oxidizer in the ethanol plant or in a backup flare at the landfill.

The project consists of 42 wells, a blower system, gas cleaning and pressurizing system and a 1.25-mile pipeline to the ethanol plant. L.P. Gill Inc. owns and operates the landfill, as well as a trash and recycling pick-up business that serves parts of Iowa, Nebraska, and South Dakota (Sioux City region). The landfill opened in 1981 and is not expected to close until 2060.

L.P. Gill signed a gas purchase agreement with Siouxland Ethanol in July 2006. As part of the agreement, L.P. Gill provided the capital to develop and build the project, including all infrastructure at the landfill, the pipeline to the ethanol plant, as well as contingent obligation to pay for certain upgrades to the ethanol plant’s equipment to enable it to burn landfill gas.

Once at the ethanol plant the landfill gas is blended with natural gas in thermal oxidizers. The system can handle variable flows from the landfill as production increases with waste in place.

In the community

L.P. Gill operates a small landfill that is not required by state, federal, or local regulations to capture its methane emissions. The facility improves local air quality, reduces odor in surrounding areas, and leads to reductions in the demand for natural gas that, although not formally credited, serve as an important illustration of successful use of “waste” gas.

The local and nation community has benefited from L.P. Gill’s very early commitment to establishing carbon credits using rigorous international standards was a laudable forward-looking approach. For these and other reasons, this project is a past winner of the EPA’s Landfill Methane Outreach Program’s “Project of the Year” award.

The community has also benefited from construction jobs related to the project, creation of two full time jobs at L.P. Gill, and lower and more predictable energy costs at the local ethanol plant.

In an interview, Leonard Gill, founder of L.P. Gill, gave this advice to other independent landfill operators:

“I wouldn’t recommend that other independent landfills do these type of projects without revenues from carbon offsets. After all, even if a project’s energy revenues are disrupted, the carbon revenues can keep the system running.”

We want our projects to stand out as role models. Therefore we look favorably on projects that demonstrate new technologies, or are well-run and well-publicized, or which make it clear that a sensible financial return is possible.

The L.P. Gill landfill has attracted considerable attention in the local press. Highlights include a 25th year celebration and volunteer clean-up day, in addition to coverage of the launch of the landfill gas-to-energy project. In addition, Leonard Gill was awarded the W. Edwards Deming Entrepreneurial Excellence Award by the Chamber of Commerce of Sioux City, IA. L.P. Gill was named Recycler of the Year in 2004 by Keep Nebraska Beautiful and received the Developer of the Year award for Dakota County Nebraska in 1995. Leonard Gill is on the Board of Directors for Briar Cliff University located in Sioux City, IA and Wayne State/Northeast Community College in Nebraska. We’re proud to work with leaders like Leonard and help them demonstrate that smaller landfills can make big environmental improvements and provide energy to local industry.
