CAWQ 2021 Symposium
A case study of a full-scale food waste digester failure and recovery was presented at the Value of Biogas West Conference in Vancouver. This case study demonstrates the need for balance in anaerobic digester feedstock as too much of the coveted FOG can be problematic. Read More
WEAO Conference – Lessons Learned from Operating Energy Digesters
Azura’s experience with food waste anaerobic co-digestion (AnCoD) and our work at energy producing biogas plants was the basis for one of two podium presentations scheduled for the 2020 WEAO conference. Due to the COVID-19 pandemic, the in-person conference and presentations were cancelled, luckily the papers were still published. Read More
Getting to Net Zero Energy Wastewater Treatment
The third Getting to Net Zero Energy event was hosted by the Ontario Water Consortium in February of 2020. This event continued the momentum toward getting five municipal wastewater treatment facilities converted to net zero energy by focusing on anaerobic codigestion to produce biogas. The biogas produced through anaerobic digestion of comingled food waste, organic waste, and sewage biosolids can be used to produced renewable electricity, or purified to produce renewable natural gas (RNG).

WEAO Conference – Advanced Digester Monitoring
Azura had 2 presentations accepted by WEAO and was schedule to be presented at the 2020 WEAO conference. Due to the COVID-19 pandemic, the in-person conference and presentations were cancelled, but the papers were able to be published online. One of the presentations explored the possibility of establishing an advanced digester monitoring tool that could predict if the digester was susceptible to imminent failures or crashes. Read More
WEFTEC Conference – Experience with Anaerobic Codigestion
Lessons learned from three years of working with full-scale anaerobic codigestion facilities were compiled and shared by Azura’s Dodge Yu and David Ellis at this year’s virtual WEFTEC 2020 conference. Dodge gave the presentation which summarized the observations, data gathered, and lessons learned during Azura’s years of working with farm-based anaerobic digesters in Ontario, Canada. The presentation covers feedstock handling, digester monitoring parameters, as well as digestate end product management. Read More
