… of agriculture. This Master thesis is in the framework of the Climate School.Global warming is a problem that gets much attention today. Global warming and climate change are two subjects that are very much in focus on the political agenda. The municipalities of Sweden have a …
Förbränning av hushållsavfall kontra biogas : miljömässiga och ekonomiska perspektiv med utgångspunkt i Oskarshamns kommun
… ekonomiska aspekter. Detta är en livscykelanalys där två metoder har använts, Global Warming Potential med ett 100 års perspektiv samt ReCiPe Endpoint. Den funktionella enheten är 1 ton hushållsavfall. Genom att röta det organiska hushållsavfallet och förbränna det övriga kan …
ekologisk gård självförsörjande med drivmedel
… and usage of the ethanol in the end. This is assessed by calculation of global warming potential (GWP), acidification potential (AP) and eutrophfication potential (EP). The impact of GWP is dependant of the amount of CO2, CH4 and N2=. The fuel that are used for cultivation is …
… the Stockholm Archipelago. Focus is on how much the biogas plant reduces the global warming potential and if it is economically profitable. It was concluded that a biogas plant with 100 m3 digester and a substrate volume of 1000 m3 per years is well adapted to the islands …
… heating and diesel generator with rape seed oil are systems with negative global warming potential, mainly due to the simultaneous production of power together with heat. Compression cooling has the highest GWP and the remaining systems shows a small GWP. Rape seed diesel …
substance flow analysis on a regional level
… to a series of environmental problems such as eutrophication, acidification, global warming and smog. The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society. The society was …
Modellkonstruktion och Utvärdering med ORWARE
… showsthat anaerobic digestion of organic waste is beneficial for reduction of global warming butlikely has a greater economical cost than the conventional methods, e.g. incineration.
… decomposes rapidly, contributing to increased greenhouse gas emissions and global warming. Rapid decomposition partly depends on the degradability of the material itself. In this literature review, I examine which coastal plant species dominate different locations along the …
En jämförande systemanalys avseende exergi, miljöpåverkan samt återföring av närsalter
… the separated system, where food waste is mixed with closet water. Also the global warming potential of the new technique is lower. However, conventional treatment is better from an exergy-perspective. This is mostly due to the high energy consumption as a result of the reversed …
livscykelanalys (LCA) av svenska jordgubbsodlingar
… lufttemperatur, den så kallade växthuseffekten. Mellan 1970 och 2004 ökade de globalaväxthusgasutsläppen med cirka 70 %. (Naturvårdsverket 2008a). Ungefär 25 % av Sveriges klimatpåverkande utsläpp uppskattas komma ifrån matkedjan. (SIK 2008).För att kunna sänka de …
… life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use. Two alternatives for utilization of the biogas werealso compared through LCA, generation of electricity and the use …
comparing biogas production to incineration
… life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use. Two alternatives for utilization of the biogas werealso compared through LCA, generation of electricity and the use …
… there is a controversial debate about that we must reduce our impact on the global warming; therefore both the Government and the local authorities have invested heavily in developing renewable energy in Sweden. The major development on the wind power market can be seen as a …
En LCA av gris och olika förändringar i produktionssystemet i syfte att minska klimatpåverkan.
… som foder och då matavfall. Detta är en screening-livscykelanalys där endast Global Warming Potential tas i hänsyn med ett 100 års perspektiv. Den funktionella enheten(FE) är 1 kg ben- och fettfritt griskött. Genom att använda förnyelsebar energi i form av vindkraftproducerad el …
and preparations for a metagenomic survey of virus in mosquitoes
… and wild animals are forced to live close together. In combination with the global warming, leading to extreme weather such as floods and storms, this allows both new and old pathogens to emerge. The number of "emerging infectious diseases", EIDs, has increased in recent years …
