Biogas: för en hållbar utveckling

Denna uppsats belyser processen där Biogas bildas och hur denna process utnyttjas av människan. Människan kan använda Biogas till att driva fordon, alstra el och värme och biprodukterna från processen kan användas som gödningsmedel till lantbruk. Vi gör en jämförelse mellan Biogas som naturresurs och andra energikällor för att visa hur Biogas kan vara en alternativ energikälla för framtiden. Uppsatsen behandlar även ett miljöperspektiv där vi analyserar hur Biogasen påverkar den miljö vi lever i. Det vi vill ta reda på är om Biogas är en naturresurs, nu och i framtiden, som kan nyttjas för att minska belastningen av miljön..

Biogaspotentialen av matavfall sorterat ur hushållsavfall.

To achieve the Government's milestones for 2018, which means that 50 % of food waste shall be separated from household waste and undergo biological treatment (composting or anaerobic digestion).   Hultsfred, Högsby and Vimmerby are three adjacent municipalities of Kalmar, county Småland. During 2012 and 2013 analyzes were performed on their household waste to determine its composition. The household waste is currently collected in one fraction. The work, examines how much food waste the household waste contains. From the amount of food waste, the Biogas potential is examined - how much food waste Biogas generates and how much energy it corresponds to.   Food waste is broken down by microorganisms under anaerobic conditions (anaerobic digestion) in a Biogas plant.

Materialvagnstransport

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale Biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with Biogas. Some cases in the establishment of Biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Biogasinvesteringar i Linköping : samhällsekonomiskt lönsamt eller inte?

Since some years Linköping has invested in Biogas production, mainly from offal's, residuals from food industry and manure. The municipality goes for Biogas in the local traffic and in all transportation. It is also possible for private car owners to run their cars on Biogas. The purpose of this essay is to perform a cost-benefit analysis and examine if the project has been beneficial from a social point of view. The effects have been identified, measured and monetarily valued. The essay is limited to include the year of 2006 only.

Factors for success in Swedish biogas : a study based on the Swedish agricultural sector

The energy sector of modern time is currently faced with several challenges. These are both production oriented and environmental oriented in nature. The energy of the future is intended to support an increasing demand while at the same time reduce its environmental affection. This stresses a development towards production methods of renewable energy. Among the existing methods, Biogas is presented as an attractive alternative.

Tubular polyethylene biogas digesters : development and testing of a biogas technology in Malawi to reduce deforestation and support climate change mitigation and adaptation

The aim of the study was to install a Biogas system consisting of three tubular polyethylene Biogas digesters at a rural household in Malawi and to evaluate the constructed Biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, Biogas production, Biogas composition and system functionality were made. The results of the study show that a Biogas system with tubular polyethylene Biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.
