From waste to energy Biogas production is part of the circular economy, as biogas is produced from waste feedstocks such as biowaste, sewage sludge, manure and other industrial and agricultural side streams. The organic matter generated as a by-product of biogas production is high in nutrient content. These nutrients can be further recycled for use in industry and agriculture. Gasum is dedicated to procuring more renewable gas to satisfy the increasing demand for sustainable energy. Gasum's goal is to offer 7 TWh of renewable gas to its customers yearly by 2027, including biomethane and e-methane. A large portion of this volume relies on establishing long-term partnerships with trusted and certified biogas producers throughout Europe. Achieving this goal would mean combined carbon dioxide reduction of 1.8 million tons per year for Gasum's customers.
