On March 4-6, 2024, as part of the project “Green transformation in practice: demonstration and dissemination of the benefits of biogas production from bio-waste” implemented jointly by the Institute of Environmental Protection-National Research Institute (IOŚ-PIB) and Vista Analyse, a study visit to Norway was held. The visit was attended by representatives of the Polish partner IOŚ-PIB, the Tomaszów Mazowiecki City Hall and the Water and Sewage Management Plant in Tomaszów Mazowiecki.
During the first day of the visit, participants discussed the project’s progress and attended a presentation by the Biogas Norge association. Biogas Norge brings together companies and organizations involved in developing the biogas market in Norway. Its members represent the entire biogas value chain, from suppliers and producers to distributors and end users.
On the second day, participants visited a sewage treatment plant and its biogas plant belonging to the municipalities of Oslo, Bærum and Asker. VEAS, the largest sewage treatment plant in Norway, has a capacity of over 800 thousand person equivalents, treating approximately 100 million m3 of sewage annually. From the resulting sludge, the plant produces 40,000 tons of biofertilizer, 60 GWh of biogas, and 5 thousand tons of ammonium sulfate. The produced biogas undergoes refining and liquefaction into biofuel (bio-LNG) at the refinery. The third day focused on discussions regarding the preliminary feasibility study, a key outcome of the project, and the catalogs of good practices. In the latter part of the day, a representative from Biogass Oslofjord presented the local conditions of biogas production and utilization in the Oslo Fjord area.
