1. Fermentative hydrogen and methane productions using membrane bioreactors
Sammanfattning : The role of energy as a stimulant for economic growth and environmental sustainabilityof any nation has made the focus on green fuels, including fermentative hydrogen (bioH2) andmethane (bioCH4), to be a priority for the World’s policy makers. Nigeria, as the most populousAfrican country, with worsening energy crisis, can benefit from the introduction of the bioH2 andbioCH4 technologies into the country’s energy mix, since such technologies have the potential ofgenerating energy from organic wastes such as fruit waste.

2. Methane and Volatile Fatty Acids Production from Toxic Substrate
Sammanfattning : Challenges caused by climate change and global warming have created a demand for improvements in resource recovery and the promotion of a circular economy. Waste management is one such challenge for which more recycling options are required for producing materials and energy sources from wastes. LÄS MER
3. 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
4. Increase of Biogas Production at Wastewater Treatment Plants Addition of urban organic waste and pre-treatment of sludge
Sammanfattning : Anaerobic digestion of organic matter results in the production of biogas, which can be used to replace fossil fuels. There is potential for increased biogas production at wastewater treatment plants by digesting urban organic waste either separately or together with the sludge. Biogas production could also be increased by sludge pre-treatment. LÄS MER
5. Renewable Energy and Nutrient Valorization from Anaerobic Digestion : Resource-Efficient Solutions
Sammanfattning : This thesis presents a comprehensive analysis aimed at understanding process performance, methane yield, and key influencing factors within the context of solid-state anaerobic digestion (SS-AD). SS-AD is used to treat organic material with high solids content, which can be challenging to address by alternative methods. LÄS MER
