1. Industrial Bioprocess Developments for Biogas and Ethanol Production
Sammanfattning : Current biofuels face a noteworthy misfortune on commercialization because of its economiccomparison with low-cost fuel from the oil reserves. To compete with gasoline as a fuel, thebiofuels need to be economically feasible and demonstrated on a large-scale. LÄS MER
2. Anaerobic digestion of horse manure : renewable energy and plant nutrients in a systems perspective
Sammanfattning : In horse keeping horse manure is produced, which can be utilized as a fertilizer or considered a waste. Horse manure constitutes a resource in terms of both plant nutrients and energy. In addition energy policies and objectives aim at replacing fossil fuels with renewable energy sources. LÄS MER
3. Biogas in Sweden - Opportunities and challenges from a systems perspective
Sammanfattning : Addressing today’s challenges of reducing our dependence on fossil fuels and related emissions of greenhouse gases requires measures such as increased energy efficiency and replacement of fossil energy carriers with renewable ones. Biogas is one of the fastest growing renewable energy sources in the world and the overarching purpose of the research presented in this doctoral thesis is to explore the prospects of an increased production and utilization of biogas in a Swedish context.

4. The potential of industrial hemp (Cannabis sativa L.) for biogas production
Sammanfattning : Biofuels are currently produced from agricultural crops, and an increasing use of crops for this application is expected in the EU in the years to come. The dominating crops cultivated in the EU for biofuel production today have a relatively large environmental impact. LÄS MER
5. Valorisation of fish waste biomass through recovery of nutritional lipids and biogas
Sammanfattning : Commercial fish catch in Eastern Africa is dominated by Nile Perch. Of the fish that is processed for human consumption, 30-40% is wasted. Currently, these wastes are not fully utilized; they are sold off at low price, converted to low valued products or left to decompose leading to environmental pollution and wastage of bioresource.
