Anaerobic Digestion

Using anaerobic digestion, our facilities create carbon-negative, renewable natural gas (RNG) utilizing waste that is otherwise a byproduct of your operation. While the concept is simple, the implementation can be complex. SKS is here to navigate the process with you.

How It Works

Put simply, anaerobic digestion is the production of biogas after organic materials like manure and food processing waste are broken down by bacteria in an oxygen-free environment. This process results in two valuable products – biogas and digestate. The biogas is purified to separate the methane from other inert gasses. The purified methane, or RNG, is then ready for pipeline injection while the other components, such as CO2, are captured through the filtration process. The digestate is the solid byproduct created from the anaerobic digestion process and can be used to create nutrient-rich fertilizer, livestock bedding, and other soil amendments such as compost. Additionally, our facilities help to protect waterways from runoff, returning treated water back to the site for recycling. Odors are also greatly reduced since the need for open lagoons can be minimized by directing the waste stream into airtight anaerobic digester tanks.

Project Benefits & Opportunities

Beyond just financial returns, biogas facilities offer a sustainable investment opportunity that delivers numerous benefits for the environment, the community, land owners, and investors.

Revenue Generation

Convert your waste stream into cleaned, conditioned biogas that can be monetized through injection in to the natural gas pipeline.

Operational Improvements

Manage your organic waste more effectively, reducing cost, preventing nutrient loss, and enabling future growth.

Environmental Sustainability

Capture greenhouse gasses, reduce odors, and eliminate potential contamination through water recycling and reuse.
