1. Biokolsanvändningen i Sverige : Vad krävs för att svenska lantbruk, kommuner och trädgårdsindustrin ska börja använda eller utöka sin användning av biokol?
Kandidat-uppsats, Linnéuniversitetet/Institutionen för kulturvetenskaper (KV)Sammanfattning : The amount of carbon dioxide, CO2, in the atmosphere is continuously rising due to human emissions caused by combustion of fossil fuels and changing of land use. In a very short time several measures need to be taken in order to reduce the amount of CO2 in the atmosphere and thereby slowing down climate change as much as possible. LÄS MER
2. Markkolets betydelse för åkermarkens bördighet : vilka effekter kan väntas av tillförd biokol och andra kolinlagrande åtgärder
Kandidat-uppsats, SLU/Department of Biosystems and Technology (from 130101)Sammanfattning : Biokol är en möjlig kandidat till att motverka den höga koldioxidhalten i atmosfären. Genom pyrolysering av biomassa bildas biokol, som är en hårdare inbunden form av kol. Detta gör att biokol bryts ner långsammare. LÄS MER
3. Fertiliser derived from human urine : novel media for alkaline urine dehydration
Master-uppsats, SLU/Dept. of Energy and TechnologySammanfattning : Every year, each human excretes approximately 4 kg of nitrogen, 1 kg of potassium and 0.3 kg of phosphorus through their urine. In conventional wastewater treatment, these nutrients are usually not recovered for agricultural production, although they can enhance plant growth. LÄS MER
4. Agricultural waste and wood waste for pyrolysis and biochar : An assessment for Rwanda
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik; KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : A high priority in order to combat climate change is disposal of waste. In low-income countries, a large portion of biomass residues generated in the forestry, agricultural and industrial sectors could be usable, instead of being seen as waste. For instance, it could be converted into biochar, which is proven to have many environmental benefits. LÄS MER
5. Carbon Negative Heat and Power with Biochar Production : An Economic Analysis of a Combined Pyrolysis and CHP plant
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : On the fourth of November 2016, The Paris Agreement entered into force, stating that nations worldwide should pursue efforts to limit the global temperature increase to 1,5 °C. Since then, the Intergovernmental Panel on Climate Change has specified that carbon dioxide removal, such as biochar sequestration, is necessary to achieve this goal. LÄS MER
