Ameresco's Neogenyx Fuels Breaks Ground on Nebraska Manure-to-Gas Facility

Ameresco, through its subsidiary Neogenyx Fuels, has broken ground on a renewable natural gas facility at the Adams Land & Cattle feedlot in Broken Bow, Nebraska, the company's first agricultural RNG project. The facility will use eight anaerobic digesters capable of generating more than 4,400 standard cubic feet per minute of biogas, expected to produce approximately 1.2 million MMBtu of pipeline-quality renewable natural gas annually once upgraded, while reducing greenhouse gas emissions by approximately 63,700 metric tons per year.

 

Why Anaerobic Digestion Produces Two Valuable Outputs From One Waste Stream

 

The facility is designed to capture manure from the feedlot and convert it into renewable natural gas through anaerobic digestion, a process in which microorganisms break down organic material in the absence of oxygen, producing biogas as a byproduct that can then be refined into pipeline-quality gas. Beyond the gas itself, the process leaves behind solid and liquid digestate material, which this project will reuse onsite as livestock bedding and agricultural fertilizer, rather than treating it as waste requiring separate disposal.

That dual output matters because it converts what would otherwise be considered manure management, a routine and often costly operational requirement for large-scale cattle feedlots, into a facility generating two distinct commercial products from the same underlying waste stream: energy sold as renewable natural gas, and a byproduct usable directly within the same agricultural operation as bedding and fertilizer, potentially reducing the feedlot's need to separately purchase these inputs.

Why the Bio-LNG Maritime Reference Signals a Different Demand Pathway Than Domestic Pipeline Gas

 

Neogenyx Fuels CEO Michael Bakas specifically noted the project's potential to "support bio-LNG production for global maritime markets," a detail that extends this facility's relevance beyond domestic pipeline gas distribution into international shipping fuel demand. Bio-LNG, liquefied biomethane produced from renewable sources like agricultural waste, addresses a genuine and growing demand category within maritime shipping specifically, as the industry faces increasing pressure to reduce its emissions and adopt lower-carbon fuel alternatives to conventional marine fuel oil, a dynamic visible elsewhere in recent reporting including EnerPure's used motor oil recycling project targeting marine fuel markets and Shanghai Electric's record biomethanol bunkering operation.

That connection positions a rural Nebraska cattle feedlot's manure management infrastructure as potentially feeding into a global maritime decarbonisation supply chain, an application considerably removed from the facility's immediate local context, illustrating how agricultural waste-to-energy projects increasingly serve demand pathways extending well beyond their originating region or even their originating industry sector.

 

What the Emissions Comparison Reveals About the Project's Climate Scale

 

The project's projected 63,700 metric tons of annual greenhouse gas emissions reduction is described as equivalent to the carbon sequestered by roughly 63,800 acres of US forest each year. That comparison gives a concrete, relatable scale to an otherwise abstract emissions figure, translating a technical greenhouse gas metric into a physical land area comparison that helps illustrate the magnitude of climate benefit a single facility processing manure from one feedlot operation can deliver.

That scale is notable given the facility's relatively contained physical footprint and single-feedlot feedstock source, illustrating how methane-focused waste-to-energy projects can deliver outsized climate benefit relative to their physical scale, since methane itself carries a considerably higher near-term warming potential than carbon dioxide, meaning capturing and converting manure-derived methane into usable energy rather than allowing it to escape into the atmosphere through conventional manure management delivers a meaningful climate benefit distinct from the emissions avoided by the renewable natural gas displacing fossil natural gas in its end use.

What the Political and Industry Attendance Signals About the Project's Broader Positioning

 

The groundbreaking ceremony drew Nebraska Governor Jim Pillen, US Senator Pete Ricketts, and American Biogas Council Vice President of Policy Heather Dziedzic, alongside company executives from Ameresco, Neogenyx Fuels and Adams Land & Cattle. That level of political attendance, spanning both state and federal elected officials alongside a national industry trade association representative, suggests this project has been positioned as significant not only for the individual companies involved but for Nebraska's broader agricultural and energy economic development narrative, consistent with Ameresco Chief Marketing Officer Leila Dillon's framing of the project as "a blueprint for how American agriculture can play a larger role in the global energy economy."

Adams Land & Cattle CEO Abram Babcock connected the project directly to the feedlot's own long-term sustainability goals, describing it as "an important step in advancing our sustainability goals and supporting our vision of building a business for generations to come," framing the RNG facility as extending the operation's own multi-generational business planning rather than representing an isolated, one-time environmental initiative disconnected from the feedlot's core cattle operations.
