1. Ogräsfrönas överlevnad i biogasanläggningar : en litteraturgenomgång och ansats till metaanalys
Kandidat-uppsats, SLU/Dept. of Crop Production EcologySammanfattning : Sveriges energibehov 2020 var 508 TWh och av det är kärnkraft, biobränsle, olja och vattenkraft de viktigaste energislagen. På grund av att biogasproduktion har ett netto noll utsläpp har regeringen har valt att investera 40% av klimatklivets budget till dessa projekt. LÄS MER
2. High-loaded thermophilic anaerobic digestion of mixed sewage sludge : A pilot study
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Municipal wastewater treatment plants (WWTP) are important infrastructural components in a society and also important for sustainability. In a WWTP the most common treatment configuration is mechanical, biological, and chemical treatment of the wastewater. LÄS MER
3. Produktion av flyktiga fettsyror genom anaerobisk rötning av pappersmassa och papperslam
M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Recently, there has been an increased interest in the production of volatile fatty acids from pulp and paper sludge using an immersed membrane bioreactor during anaerobic digestion. The production of biogas through anaerobic digestion has been a hot topic in recent years, but it is no longer economically viable due to competition from fossil fuels. LÄS MER
4. The feasibility of using macroalgae from anaerobic digestion as fertilizer in Grenada : A literature study of the potential use of residue as fertilizer in Grenada, and a complementary laboratory study to evaluate the biogas potential
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Coastal areas in Grenada and the Caribbean are experiencing an abundance of stranded macroalgae. Climate change and eutrophication are probable causes of this inconvenience. This leads to logistic and economic dilemmas for the Caribbean societies. LÄS MER
5. Production of volatile fatty acids from anaerobic digestion using food waste, sludge and cow manure
M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Volatile fatty acids (VFAs) are important building blocks for the chemical industry. These acids can be produced through environmentally friendly processes from a variety of wastes, such as food waste, sludge and cow manure, through anaerobic digestion (AD). The main objective of this thesis was to investigate which operating parameters (e.g. LÄS MER
