The digestion facility for the production of biogas is one of the bigger in Sweden, treating about 85,000 tons of organic material every year. The facility receives manure, industrial organic waste from nearby food industries and pretreated organic household waste. The company is owned by the municipality of Kristianstad and it delivers biogas to the large utilities company E.ON and bio-fertilizer from production residues to the region's farmers.

More Biogas Småland was formed in February 2011. The Company has 22 co-owners of which 18 are farmers in the near region of Kalmar.
More Biogas has a fermentation plant, the plant produce compressed vehicle fuel for local use. Raw material is manure from farmer´s farms and food waste from households in the neighboring municipalities.
Two sewage treatment works in Stockholm are producing biogas from sewage sludge. After having purified the gas, it can be used for both heating and vehicle fuel and in addition creates no net emissions of carbon dioxide. Consequently, the treatment works have reduced their amount of emissions and become energy suppliers. Therefore, sewage sludge is no longer an environmental problem, but an important energy resource.
A small recycling centre in Huddinge municipality produces biogas using organic waste, which is unique in the Stockholm region. Despite the fact that only a few tons of biogas is produced every year, the plant brings important knowledge for future projects.
When opened in spring 2007, the Gasendal plant, was the largest biogas upgrading facility in the world.
The plant receives biogas from Gryaab, a local wastewater treatment plant, and upgrades it to natural gas quality. The gas, which is injected into the natural gas grid, is used primarily as vehicle fuel in accordance with the green gas principle, in a way similar to the trade in green electricity. By replacing petrol with biogas in vehicles, carbon dioxide emissions is cut by up to 15,000 tons per year.
At Nynäs gård, there is a biogas installation, which is designed for the farm's phosphorus needs. The farm does no longer need to purchase any chemical fertilizers, nor does it need to buy fuel for its vehicles.
Sjölunda Wastewater Treatment Plant, Malmö At the Sjölunda plant in Malmö wastewater from 550,000 inhabitants is treated. The plant was built in 1963. Recently expansion of biological treatment has reduced the use of precipitation chemicals to meet the Swedish requirements and the plant has at the same time reached emission requirements of organic compounds, phosphorous, and nitrogen. The sludge produced is used at the plant’s own production unit for biogas.
