The most expensive part of an anaerobic digester are often the corrosion resistant tanks. Since digester volume is one of the most valuable assets of a plant because that determines how much you can feed – preserving and measuring digester volume might just be one of the most valuable methods for digester optimization.
Is your biodigester making less RNG than estimated during the feasibility assessment? One common cause is a phenomenon that Azura calls SLAC – Solids Loss on Aging and Collection.
In the biogas and RNG industry, it’s becoming more clear that AI is neither hype nor magic—it’s a tool. And like any tool, its value depends on how well it’s understood, integrated, and used.

Grit is the silent saboteur of anaerobic digestion systems. Though it often makes up less than half of 1% of a feedstock by weight, grit can cause outsized problems.

Sudden hydrogen sulfide (H2S) spikes in your digester? In your feed tanks? One common culprit is feeding a large load of high protein feedstock too quickly.
How to avoid Hydrogen Sulfide spikes from high protein feedstocks Read More »
Foam is a sticky, slippery mess that most digester operators have seen one time or another. While slip, trip, and fall risks are obvious, there are other biosafety hazards that need to be considered before rushing to clean up.
More Than a Mess – Why Digester Foam Poses Both Physical and Biosafety Hazards Read More »
The only currently established, potentially carbon-negative fuel in the world is energy produced from waste. As we seek to reduce our carbon footprint, codigesting food waste at sewage treatment plants presents an excellent opportunity to maximize existing resources and create a more sustainable future.
From Trash To Treasure: Maximizing Renewable Fuel with Codigestion Read More »
Foam is a messy, sticky, and smelly problem in biodigesters. But why does foam form in an anaerobic digester in the first place?
Anaerobic digester biology is most sensitive and fragile during startup and commissioning (S&C). This article highlights 5 key considerations that are often overlooked during S&C of anaerobic digesters.
If lab testing indicates that your digestate might contain too much ammonia, what can you do? There a number of steps to reduce problematic gasses in an anaerobic digester.
