Biogas is a climate-friendly energy form which also enables nutrient recycling. However, it can pose a risk of nutrient leaching to water bodies if the management of digestates and wastewater from biogas plants is not carefully planned. The Sustainable biogas project, funded by the EU Interreg Central Baltic programme, aims to promote the sustainability of biogas from the water protection point of view.

The project is implemented by John Nurminen Foundation, Centre for Economic Development, Transport and the Environment for Southwest Finland, Finnish Biocycle and Biogas Association, Latvian State Environmental Services and Latvian Biogas Association.
