BAL Langenau

In 2009 Christiaens Group and Biogas Anlagenbau Langenau (BAL) started a cooperation. BAL runs several dry anaerobic digestion facilities.
The Langenau Dry AD facility consists of 7 gas tight tunnels. The tunnels are filled by loader(1) after carefully mixing the different input materials and inoculum.
Only 5-15% inoculum is required. After the doors are sealed, the waste is sprayed with percolate from the percolate tank.

AHA Hanover

In this facility, 120.000 t/a of MSW is collected and separated. The small,organic fraction will be treated anaerobically in order to derive methane gas. The residue which comes out of the anaerobic digesters is going into the Christiaens Composting Tunnel system, these tunnels will aerobically treat this material.
