Doosan Enpure has completes laboratory scale trials, overseen by Birmingham City University, of its sonixTM process to increase the biogas yield from the anaerobic digestion various waste feedstocks.
The technology applies ultrasonic sound energy to feedstocks to break open cellulosic barriers enabling the anaerobic digestion biology more ready access to digestible content.
The company explained that the process is fully containerised with plug and play design meaning the new plant is operating within days of arrival on site.
According Doosan Enpure the tests proved so successful that it has committed over £1 million to an R&D project to build and operate a full size agricultural AD plant sonix™ system. That project has now been operational for six months.
The company added that the sonix™ process can handle a range of throughput sizes and can be retro fitted to an existing plant or included in new build facilities. It is claimed to give the developer high returns and payback in under five years.
“The objective of our sonix™ project is to expand upon our promising laboratory scale results by demonstrating on a full scale operational plant the biogas yield improvements, and reduced cake disposal quantities which together will offer existing and proposed plant operators significant investment return benefits,” commented Doosan Enpure’s waste & energy business development manager, Kevin Clarke.
With over 400 anaerobic digestion plants in operation, and a similar number in the planning process, the company said that there is a significant opportunity for the new technology in the country.
