Abstract [en]

To decrease the climate impact and the use of fossil fuels in the society we have to change our way of living so it becomes more sustainable and ecofriendly. Production of biogas can in different ways contribute to this change since it is a biological waste treatment method that takes advantage of the energy in the organic material, the substrate. The purpose with this thesis has been to study the prerequisites in the community of Älvdalen for local production of biogas. Data have mainly been collected from literature and from Nodava AB, the water and waste company of the community. The substrates in this study consist of food waste, manure, wastewater sludge and slaughter waste from fish. The manure represents the largest part with respect to the biogas potential. The results include a presentation for how much the calculated biogas potential corresponds in heating households, production of electricity and how many cars that can be filled up with upgraded gas per year. The result in the study show there are conditions for local production of biogas within the community of Älvdalen. Calculations show that there are possibilities to produce energy corresponding totally 2,5 GWh from substrate occurring locally in the community.
