“Good digesters run on good data. Dave and Azura helped us get better data on our two digesters so we could make better decisions. Regular testing of our digesters helped us manage our feedstocks, balance their nutrition, and avoid ammonia and LCFA toxicity problems. Good biology, balanced nutrition, and stable operation have helped us avoid serious foaming problems. He helped us improve our biology. Easy to contact by phone or text or email, Dave and Azura really made a difference.“

“A dead digester, not producing any gas, that’s what got us to start working with Azura. Starting with detailed laboratory testing, Dave’s processes pinpointed the problem and got our digester back to 80% production in only two months. Azura’s ongoing monitoring had us hit full production a few weeks after that. Once we were stable they developed a feedstock recipe to maintain stable production. We have high methane content, and no foam. Since then, even with engine issues, we’ve averaged more than 90% production. Their emphasis on better testing for better decisions really pays off.”
