Dry digestate as a heat source.
The DRANCO installation in Wijster, began operation in 2012 and processes the organic wet fraction of municipal residual waste after pre-treatment.
The digester produces biogas that is upgraded to green gas and injected into the national gas grid.
Attero deliberately selected the dry DRANCO process so that the digestate can be sent directly to the on‑site waste‑to‑energy incineration plant without any dewatering.
This integration with the thermal treatment facility is part of a broader system in Wijster, where non‑recyclable waste fractions are incinerated in three incineration lines to generate electricity and steam. The steam produced is partly sold to the adjacent Energy Transition Park, where industrial users apply it in their production processes.
The site combines anaerobic digestion, composting, waste separation, recycling, and thermal treatment, making it one of the most comprehensive circular waste hubs in the Netherlands.
Thanks to the integration of digestion and thermal treatment, the site maximizes energy recovery from waste streams while minimizing disposal.
