Want to know what make biogas and RNG projects work? Then @biogasworld1106 & Azura’s “Biogas Project Feasibility Workshop for Beginners” webinar is for you! Join us on May 13th to learn how to: - Formulate targeted, high-level questions to assess risks associated with project feasibility and execution. - Assess the potential benefits, and community impacts of a biogas project. - Independently evaluate the high-level feasibility of a biogas project, without relying on external consultants. There will be two sessions to accommodate different time zones: Session 1: 9:30-11:30 EST, for North and South America, Europe, and Africa Session 2: 20:00-22:00 EST, for Australia and Asia Reserve your spot today – https://www.eventbrite.ca/e/biogas-project-feasibility-workshop-for-beginners-registration-1311863100849 #Biodigester #AnaerobicDigestion #Biogas #ProjectDevelopment
Upcoming Training – Biogas Project Feasibility Workshop
#TeamPlaid headed to Quebec for the RNG Forum 2025 hosted by @biogasworld1106. The conference was filled with insightful sessions looking at potential opportunities and strategies to expand Canada's biogas and RNG sector. Thank you to everyone that attended the "Biogas & RNG Site Operation: Hands on Experience" panel. We had a great discussion about the challenges and opportunities for owners looking to scale from farm-based anaerobic digestion to co-digestion with food waste to produce RNG.

Event Recap – RNG Forum 2025
TeamPlaid had a fantastic time in Toronto at the Value of Biogas East Conference. We’d like to congratulate Peter Quosai on his wonderful presentation about grit. We’d also like to thank the Canadian Biogas Association for once again hosting this event and giving us the opportunity to meet so many individuals and companies that are working to advance the biogas & RNG industry in Canada. #ValueOfBiogas #Biogas #RNG #Sustainability
Event Recap – Value of Biogas East 2025
Is your biodigester making less RNG than you estimated during the feasibility assessment? One common cause is a phenomenon that the Azura team calls SLAC – Solids Loss on Aging and Collection. In his latest deep dive video Azura's Principal Engineer, Dave Ellis explains how despite the best efforts of calculation, real-life fuel value can be much lower than initially calculated due to estimations and assumptions that don’t account for the feedstock’s age and collection practices. Do you want to get a more accurate picture of your potential fuel value? Azura’s newsletter subscribers will receive an exclusive SLAC explanation with calculations straight into their inbox on April 8!

After more than 30 years of working with digesters, we have found that ammonia is one of the most common causes of anaerobic digester or biodigester issues, including digester foaming. So, what can you do about too much ammonia in your anaerobic digestion process? In this video, Azura’s Principal Engineer, David Ellis shares where ammonia comes from, the different types of ammonia in your digester, how pH and temperature play a role in managing ammonia, what you can do to get your digester running better and avoid ammonia-induced digester foaming. 📄 Download a copy of Azura’s Ammonia Rainbow Chart - https://lp.constantcontactpages.com/sl/QLBBKUQ/AmmoniaRainbow Chapters in this video: 00:00 What is the most common cause of digester issues and foaming? 00:17 Intro to David Ellis 00:32 What will we learn about ammonia? 00:57 What is ammonia and what are the different types of ammonia in a digester? 02:25 Total Ammonia Nitrogen (TAN) 03:34 NH3 depends on temperature and pH 03:40 Azura’s Ammonia Rainbow Chart 05:40 An example of ammonia inhibition 07:25 Too much ammonia in your digester?

Check out our website here - https://azuraassociates.com/uncover-why-your-digester-has-challenges Curious about why Dave says, “ammonia as nitrogen”? NH3 and NH4+ concentrations in watery materials like digestate are typically reported by water testing laboratories as NH3 – N and NH4+ – N. The “– N” is read as “as nitrogen”. Measuring ammonia (NH3) and ammonium (NH4+) directly is challenging. Measuring the Total Ammonia Nitrogen (TAN), the sum of the NH3 – N and NH4+ – N concentrations, is simpler and more accurate than trying to only test one form. Because of this improved accuracy, environmental regulations in many places often ask sites to report the TAN concentration, temperature, and pH rather than distinguishing between specific forms. Tracking individual nitrogen species is often impractical in routine monitoring.

Foam is a real messy, sticky, and smelly problem in biodigesters. Why is there foam in an anaerobic digester in the first place? Foam happens when these three things are true: 1. Gas bubbles form in a volume of liquid – there’s always gas bubbles. 2. A substance that traps gas bubbles is present on the surface of the liquid, i.e. surfactants. 3. An operational event hinders the bubbles from bursting in the digester. Surfactants on their own, or with long molecules, in the liquid digestate form the “skin” of the bubble. In the clip, we added soap, egg white, and oil to a cup of water. - The soap is an example of a chemical surfactant. - Egg white has long protein molecules and grease has long fat molecules, both of which can act like biosurfactants at high concentrations. As you can see, the bubbles stay at the top easily. Bubbles like this are not really an issue if the foam level doesn’t rise too much. But when we blow more bubbles and add more soap, the foam overflows and becomes a mess. Foam becomes an issue in anaerobic digesters when you get a sudden surge in gas production, sudden increase in surfactants on the surface, or both. Don’t let foam disrupt operations!
