Finnish cleantech company Ductor Corporation has developed a process that removes ammonium inhibition in biogas fermentation aiming to improve biogas economics and nutrient recycling
Ductor Corporation says its new patented Ductor fermentation technology removes over 60 percent of the nitrogen before biogas fermentation. It does this by adding one fermentation step, prior to fermentation, as well as a nitrogen stripping unit. The technology can be added to biogas plants of many different sizes and unit operations do not require skills beyond normal biogas plant operations.
“We have tried to keep it simple and straightforward - and we feel we have been successful” said Ari Ketola, CEO at Ductor Corporation. “
The company’s microbiological innovation eliminates the nitrogen dilemma by turning problem waste into profitable recyclable goods, with the result that in the near future tons of waste can be turned into renewable energy economically and efficiently. The company’s pilot plant in Finland has used 100 percent chicken manure with water recycling in the biogas process with no problem.
The first industrial-scale demonstration plant will be built in Germany, as the company is currently focusing primarily on the German market which has benefitted from an improvement in profits and is supported by current German legislation. Several sales contracts have also been signed in the northwest of the country.
Ductor is confident that there will be global demand for the technology given the huge demand for solutions to improve the profitability of biogas production across the globe.
