Comparative Analysis of Dry and Wet Fermentation Processes for Biogas Production in Northernmost Norway
This thesis investigates biogas production in northern Norway, focusing on wet and dry fermentation methods. Stemming from the Boost Nordic Biogas initiative, in collaboration with Rå Biopark, the study aims to enhance biogas production in the region. By comparing wet and dry fermentation, it seeks...
