If not purified leachate from landfills would cause damages on the environment. At most landfills in Sweden local treatment of leachate is achieved, at the rest the leachate is transported to sewertreatment. While no comprehensive legal provisions for discharge exist in Sweden …
Spridningsförutsättningar och transportprocesser i deponier samt ansvaret för förorenad mark
… master thesis encompasses an inventory and risk classification of four disused landfills within the municipality of Uppsala, Sweden. The model of the classification; ”Method of Surveying Contaminated Sites” is developed by the Environmental Protection Agency and can be used as a …
… ashes. The bottom ash has for many years been used as construction material in landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it …

Hur blir de en tillgång och för vem?
… sites for giving them new uses. This study aims to investigate how old landfills can be re-used, what has lead to the new uses, and for what and whom the transformed site will be an asset. The method used is a case study of four different landfills in Stockholm county, Sweden …
… in Sunne is a company whose main occupation is to collect the gas produced in landfills. The gas contains about 50 % of Methane which is a greenhouse gas 20 times worse than CO 2 and should therefore not be allowed to leak into the atmosphere. The Methane is in as large amount …
… of waste depositing (2001:512) at year 2001, the rules about management the landfills and leachates tightened. At the landfill Vissberga in the municipality of Hallsberg, a leachate treatment plant was constructed just a year thereafter. This treatment plant consisted of an …

… extraction is improved. The annual production will decrease with time since landfills aren’t allowed to receive more organic waste. Landfill gas is hence a large but not lasting source of vehicle fuel. The amount of available landfill gas that is possible to upgrade to vehicle …
en jämförelse mellan deponering och förbränning med energiutvinning
… produced in the region is landfilled on three different sanitary controlled landfills situated outside the city center. In order to present different solutions to the present treatment, incentives have been taken to start a cooperation project between Chile and Sweden in which …
… mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be …
… in England. The traditional way of handling waste in England is through Landfills. Land filling leads to emissions of the greenhouse gas Methane. The EU has put in place a landfill directive that is supposed to lead the member states away from land filling as a method of waste …
… mainly by anaerobic digestion of sewage sludge at sewage treatment plants, landfills and anaerobic digestion of household or industrial waste. Also cattle ma-nure from farms can be used to produce biogas. Upgrading biogas represents an increase in methane concentration from …
en studie av effekter på växthusgasutsläpp och kostnader
… with the heat plant which instead has to place some of its produced ashes in landfills. If the exergy content in the biogas is compared to that of the heat it shows that there is a point to making gas instead of incinerating the waste. The biogas has about 50 % higher exergy …
Med fokus på EU:s avfallsmål och en hållbar avfallshantering
… of construction and demolition waste has improved, and less waste goes into landfills. The concern is that the overall amount of waste being produced is not decreasing, thus calling for actions preventing the production of waste. Construction companies are relatively …
… It is therefore desirable to minimize the emissions of methane gas from landfills. This may be achieved by drain the landfill of gas. In this thesis the amount of produced methane gas at the landfill at Örebro has been calculated. Estimations have also been made of the amount of …
