The municipalty of Skellefteå collect waste from homes and workplaces and produces there own biogasfuell for use in the municipality cars and in the public buses. The Biogas plant turns organic waste into biogas. Food bio waste from homes and workplaces is selected and placed in the brown waste container so that it can be taken to the biogas plant. The fuel that comes from this plant is used in the municipality cars and in the public buses, but it can also be bought by anyone whose car can take such fuel.

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.
A researcher at the University of California Davis working in cooperation with an outside collaborator have developed a multi-stage process and system for treating organic waste materials. This process produces a high-quality compost derived from food waste and other organic materials while avoiding the environmental problems of traditional composting methods such as emissions of odors volatile organic compounds and other noxious gases.
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.
Käppalaverket is one of the world's most efficient water treatment installations, with the entire northern Stockholm as a catchment area. Apart from the fact that the installation treats water for over 500 000 people, it also produces biogas, running 100 busses.
A combined fossil fuel free process of lignocellulosic pretreatment with biological hydrogen productionType:Product
As the price of fossil fuels increase with diminishing reserves biofuel production for transportation is seen as a viable alternative for current as well as future energy demands. Microbial biofuel generation from lignocellulosic plant materials holds great promise with H2 being regarded as the gold standard since only water vapor is emitted when burned. Although the potential exists for this to be an economically viable substitute several issues are still to be resolved. Lignocellulosic plant material contains cellulose hemicellulose and lignin.
