Burns & McDonnell provides engineering, architecture, construction, environmental, and consulting solutions. They plan, design, permit, construct, and manage facilities.
We design and build the tangible and intangible, everything you see (and don’t see) that helps our cities thrive. We’ve worked relentlessly to make our clients and our communities successful since 1898, because we know safe, essential infrastructure is the foundation of a flourishing society.

We’re big on the ampersand around here. (You’ll see them everywhere at all our offices!) But it’s more than just a symbol. It’s a promise that connects the possible to the powerful. People & partners. Safety & security. Big thinking & relentless execution. Projects & potential. Collaboration & community. When you’re focused on the “and,” opportunities are limitless.


Renewable natural gas (RNG) is steadily growing in demand as a sustainable alternative transportation fuel and a drop-in replacement for traditional natural gas, helping decarbonize municipalities, utilities, institutions, and industry through its use in thermal applications and electricity generation. RNG can be produced from a variety of sources, and its utilization helps reduce greenhouse gas emissions by capturing methane that may otherwise be emitted and displacing geologic natural gas.
Leveraging RNG requires complex facilities and infrastructure to collect, process, and convert organic materials into biogas via anaerobic digestion. The type of anaerobic digestion process deployed depends on feedstock characteristics, loading rates, retention time, and the effective management of residuals (digestate) after anaerobic digestion is complete. Once biogas is generated, several processes remove impurities so it can be beneficially utilized locally or upgraded to natural-gas quality and injected into nearby pipeline networks. A critical part of any project is the efficient and accurate evaluation of the anaerobic digestion, biogas pretreatment, and upgrading processes in concert with the RNG quality requirements and overall project objectives. With decades of experience with anaerobic digestion and biogas beneficial use, we have helped develop robust and reliable processes on all types of biogas generation facilities.
Our professionals provide deep experience in the full spectrum of consulting, permitting, engineering, construction, commissioning, and compliance services. We draw on our understanding and experience with RNG producers, utilities, offtake partners, and developers to inform sensible solutions that meet your technical and financial needs.

From agricultural wastes, landfill gas, and food waste to municipal and industrial wastewater, we help you convert wastes into a valuable resource. We have served as trusted advisers, permitting specialists, designers, and constructors for numerous biogas beneficial-use projects, drawing on extensive experience applied to the unique considerations of each project or program of projects we undertake.
Our full range of RNG services helps you seamlessly go from feedstock collection and processing through pipeline interconnect. Our multidisciplinary team routinely assists with permitting, land acquisition, design, and construction of RNG facilities, distribution and transmission pipelines, compressor stations, and M&R stations from the beginning to the successful conclusion of projects.
