This BIOGEST PowerRing plant is an excellent example of a biomethane investment. It operates flawlessly and allows for the possibility of an extension to the plant whenever desired using our technology.
Due to our effective pre-treatment before going into the digester and the optimized mixing technology inside, our BIOGEST PowerRing represents the perfect solution for solid manure and agricultural wastes including stover.
After successfully commissioning the first phase of this project, two extensions were completed. In 2018, one residual circular concrete tank was constructed, then in 2020, this tank was turned into a digester. Gas production could rise by almost 80% due to process optimization and the addition of a basic digester.
With the PowerRing digester, you can make sure to get as much gas as possible out of your substrate before putting it into a (covered) lagoon.
