City of Phoenix RNG Plant Receives Honorable Mention in Fast Company’s 2020 World Changing Ideas Awards

Ameresco’s wastewater treatment biogas-to-renewable natural gas (RNG) facility recognized for its innovation and contribution to building a better world

NEW YORK and FRAMINGHAM, Mass. April 28, 2020Ameresco Inc., a leading energy efficiency and renewable energy company, today announced that its 91st Avenue RNG facility in Phoenix received an honorable mention in Fast Company’s 2020 World Changing Ideas Awards in the energy category. Organized annually, the World Changing Ideas Awards honor businesses, policies, projects and concepts that are actively engaged and deeply committed to solving the climate crisis, social injustice and economic inequality.

Designed, built, owned, operated and maintained by Ameresco, the 91st Avenue RNG facility is the largest wastewater treatment biogas-to-RNG facility of its kind in the United States. Using innovative, advanced energy technologies, the facility processes raw biogas generated on-site by the municipal wastewater treatment plant (WWTP) and converts it into RNG suitable for injection into the nation’s high-pressure natural gas pipeline. The carbon-neutral RNG produced at this facility offsets approximately 44,671 metric tons of CO2 per year — the equivalent of taking roughly 70,452 passenger vehicles off the road for one year.

“RNG is a critical component of our clean energy future and has the potential to effectively support the decarbonization of our nation’s existing natural gas pipelines,” said Michael Bakas, EVP of Distributed Energy Systems at Ameresco. “Through the unique public-private partnership that we’ve forged with the City of Phoenix, we’re able to transform waste into a source of green energy, generating revenue for the City while mitigating greenhouse gas emissions in the region that contribute to climate change.”

Now in its fourth year, the World Changing Ideas Awards showcase how some of the world’s most inventive entrepreneurs and companies are addressing grave global challenges. A panel of eminent judges selected winners and finalists from a pool of more than 3,000 entries across transportation, education, food, politics, technology and more.

“There seems no better time to recognize organizations that are using their ingenuity, resources, and, in some cases, their scale to tackle society’s biggest problems,” says Stephanie Mehta, editor-in-chief of Fast Company. “Our journalists, under the leadership of senior editor Morgan Clendaniel, have uncovered some of the smartest and most inspiring projects of the year.”
