6. Biogas from slaughterhouse waste : Mixtures interactions in co-digestion
Sammanfattning : Global environmental concerns connected to the use of fossil fuels have forced the development ofalternative sustainable energy technologies. The application of anaerobic digestion, from waste streams thatcurrently have no use, can be utilized for bioenergy production. LÄS MER
7. Bioprocessing of Recalcitrant Substrates for Biogas Production
Sammanfattning : The application of anaerobic digestion (AD) as a sustainable waste management technology is growing worldwide, due to high energy prices as well as increasingly strict environmental regulations. The growth of the AD industry necessitates exploring new substrates for their utilisation in AD processes. LÄS MER
8. Improvement of Wastewater Sludge Digestion
Sammanfattning : The reduction of sludge volumes for disposal is a topic of high interest for wastewater treatment plants (WWTP) all over the world. Steadily increasing volumes for disposal create an economic, environmental, legislative and technological challenge. LÄS MER
9. Anaerobic digestion of crop residues at low temperatures
Sammanfattning : Biogas is a renewable source of energy. Residues from agriculture contain considerable energy potential and are suitable substrates for biogas production, but in Sweden the utilization of these residues is low. The economic feasibility of biogas production in general is low, and only limited subsidies are provided by the state. LÄS MER
10. Anaerobic Digestion of Solid Residues on the Bolivian Altiplano
Sammanfattning : Anaerobic digestion and the production of biogas can provide an efficient means of meeting energy needs locally and reducing organic loading due to untreated waste material in water recipients. Furthermore, residues after anaerobic digestion may be used as a fertilizer to improve the soil in many parts of the world. LÄS MER
