ES Engineering Services deploys Ductor tech to improve biogas plants


Ductor Corporation, a provider of technology to improve waste management, energy and food production, has formed new partnership with ES Engineering Services in North America.

The partnership will leverage the microbiological method developed and patented by Ductor to improve the profitability of biogas plants significantly through enabling the use of high-grade, yet incredibly economical, feedstock in the production of biogas.

Ductor has developed a unique fermentation system that removes more than 60 percent of nitrogen from organic waste before biogas fermentation. The technology harnesses the power of underutilized biomass with high nitrogen content, such as poultry manure and many other organic materials.

The proprietary fermentation technology extracts nitrogen at an early stage, prior to the biogas production process. It then simultaneously creates by-products with commercial value, specifically, ammonia or ammonium sulfate.

Also, Ductor’s method is able to recover nitrogen and phosphorus from organic material, which are problematic from an environmental perspective. As a result, the biogas production process becomes cleaner, more manageable and can have an even great environmental benefit.

“We are confident in the cooperation with ES Engineering within North America based on their competence and long-term experience in the biogas industry,” says Ari Ketola, CEO of Ductor Corp. He added, “we fully trust ES Engineering to be successful in their role as our system integrator and we strongly believe that through partnering with them we will not only achieve our growth targets, but exceed them.”

“We have been very impressed with the technical capabilities and vision of the Ductor Team and believe that they represent what we believe to be a game changer for upgrading and new construction of anaerobic digestion facilities,’’ said Bernard Sheff, PE, vice president of Engineering for ES Engineering Services and chairman of the American Biogas Council.
