BEAR - Biogas Efficiency in Arctic Regions

BEAR project, funded by Interreg Aurora, aims to enhance the efficiency of biogas production in Arctic regions by improving process performance through three integrated research areas.

1. Optimizing the biogas process using a predictive process model for smart control. This includes planning optimal organic loading and improving the overall energy balance.

2. Investigating various biogas feedstocks (e.g., horse manure) and pretreatment methods feedstocks to improve the anaerobic digestion process.

3. Studying the dynamics of the microbial community in the biogas process and developing analysis methods for microbial detection to enhance biogas production.

The project brings together the complementary strengths of its partners - the University of Oulu contributes a predictive optimization model for smart process control, SLU advances microbiological understanding to improve reactor performance, LTU develops substrate innovations to enhance fermentation, and Luke provides energy‑efficiency modelling supported by detailed chemical analyses, while Digikierto Oy evaluates the economic impacts and develops practical deployment pathways.

The project’s main target group is SMEs - such as farms - that operate biogas plants or are planning new biogas investments. The project will also benefit other types of biogas plants. It will demonstrate how the developed solutions can improve efficiency and profitability, and reduce methane emissions. The results will be shared across the Interreg Aurora Programme area to support the biogas business potential and promote regional vitality.
