Solids injection systems for biogas plants
Efficient & robust solid feeding systems
The key to maximizing the efficiency of your biogas production
Solid matter feeding systems are essential components in biogas plants. They ensure that biomass such as straw, manure and waste is continuously fed into the digester to produce biogas efficiently.
Choosing the right feeding system is crucial for smooth, uninterrupted operation. This ensures the optimum production of your biogas plant.
With our solids feeding system, you are opting for a reliable, efficient and low-maintenance solution for your biogas plant. With two sizes (300 and 500) and versatile connection options to solids feeders from well-known manufacturers such as Strautmann, BVL, Trioliet and Havelsberger, our system can be adapted to your exact requirements.
What you can expect
