11. Gräs från våtmark som additiv i bränslepellets : Effekter på pelletskvalitet och energiförbrukning
Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Because of global warming the energy production development has progressed towards more renewable energy sources. Biomass has great potential in this matter and pellet is already a big market that has increased seven times the past decade. LÄS MER
12. Do 25 years old skid tracks restrict growth and survival? : a study on growth conditions for the planted regeneration in a rainforest rehabilitation project
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. LÄS MER
13. Analys och metodutveckling av densitetmätningar för träbränslepellets
M1-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknikSammanfattning : Pelletsuppvärmning konkurrerar idag med fjärrvärme och värmepumpar. Det är därför viktigt att reducera de problem som kan uppstå vid användandet av pellets. Ett vanligt problem som kan uppstå är söndersmulad pellets som kan sätta igen pelletspannan. LÄS MER
14. Carbon sequestration in the pastoral area of Chepareria, western Kenya : a comparison between open-grazing, fenced pastures and maize cultivations
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Carbon sequestration through restoration of degraded pastoral soils is an advocated way of mitigating global warming, and simultaneously alleviating poverty. An often proposed rehabilitation strategy is fencing of pastures, a method that was introduced to the farmers of Chepareria by the Vi-Agroforestry organization in 1987. LÄS MER
15. Cassava as an additive in biomass fuel pellet production
Uppsats för yrkesexamina på avancerad nivå, SLU/Department of Forest Biomaterials and Technology (from 131204)Sammanfattning : In this study, the effects of using fine milled cassava stems as an additive in biofuel pellet production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. LÄS MER
