Ameresco reaches mechanical completion of McCarty Road Landfill RNG plant

In the United States (US), Ameresco, Inc., a leading independent provider of energy efficiency and renewable energy solutions, has announced that it has achieved mechanical completion at its McCarty Road Landfill landfill gas (LFG) to renewable natural gas (RNG) plant located in Houston, Texas (TX). This facility has a gross nameplate in excess of 1.1 million Dekatherms per year and is capable of processing 4 500 scfm of raw LFG.

The Ameresco team broke ground on the project in the second quarter of 2020 and reached mechanical completion in early December 2020 while successfully navigating the construction challenges and equipment delays associated with a global pandemic and an active hurricane season.

This complex renewable natural gas facility was swiftly constructed amidst incredibly challenging conditions due to the steadfast execution by the Ameresco team and project partners. By leveraging advanced technologies to transform the raw feedstock into a readily available renewable fuel source, clean energy can be made available for the transportation sector. We are fortunate to have partnered with Republic Services on a project that exemplifies the green energy infrastructure of the future, said Mike Bakas, Executive Vice President of Ameresco.

The McCarty Road Landfill is owned and operated by Republic Services Inc., the nation’s second-largest recycling and waste management services provider, and is one of 189 active, modern-day landfills managed by the company. The site is also one of the largest waste disposal facilities in the state of Texas (TX).

We are proud of this innovative partnership because it allows us to utilize a natural byproduct of the landfill to create low-carbon transportation fuels and other forms of renewable energy. Last year, Republic Services set a long-term sustainability goal to send 50 percent more landfill gas to beneficial reuse by 2030. This project not only creates additional clean energy resources in the regional economy but also reduces greenhouse gas emissions and helps us meet that goal, said, Pete Keller, VP of Recycling and Sustainability at Republic Services.

This long-term and collaborative partnership will result in a reduction of more than 61 000 tonnes of carbon dioxide (CO2), which is equivalent to the displacement of 58 million gallons of gasoline over the project life.

As a leading distributor of sustainable energy solutions, we’re honored to work with Ameresco on the McCarty Road Landfill project, taking gas produced to some of the most forward-thinking organizations throughout the nation. Demand for renewable natural gas from the transportation sector has steadily risen for the past several years and we anticipate this to continue into the future because of the positive impact it offers. Organizations using renewable natural gas reduce transportation-related emissions in support of sustainability goals and lower fuel spend thanks to economic benefits like environmental and tax credits. Despite challenges experienced in 2020, we applaud Ameresco on the progress of this landfill project and look forward to future collaboration, stated Mike Koel, President of U.S. Gain

The project is expected to reach commercial operations in early 2021.
