The Sustainable Biogas project was presented to a group of local actors in Åland at a workshop on February 10th 2022. The participants heard about the report on the current state of Finnish biogas production, especially regarding the results for Åland. The representatives of Vahanen Environment Oy also presented the maps illustrating the regional distribution of nutrients implemented within the project, which can be used to identify areas of nitrogen and phosphorus surplus and deficit.
The group discussions led by Two Feathers Consulting focused on identifying the challenges of nutrient management and biogas production, finding possible solutions, and drafting the practical measures and action plan. The most significant challenges in Åland were named the use of sewage sludge, the Åland-wide surplus of phosphorus, as well as the high local nutrient concentrations and the transport costs of organic masses. Improving the quality of sewage sludge, co-operation between different actors and biochar production were raised as proposals for solutions. Improving the quality of sewage sludge and nitrogen recovery opportunities at the wastewater treatment plant could be developed in the Central Baltic project. Also, biochar could be the contaminant-free end product of sludge treatment. In addition, efforts could be made to improve co-operation and dialogue between different actors, for example in guiding the location of future biogas facilities.

The nutrient maps of Åland will be available on the project website in March.
