1. Risk of nitrous oxide emissions and potential of bioaugmentation when treating digester supernatant via nitrification-denitrification
Abstract : This thesis examines two different impacts of sidestream treatment of digester supernatant via nitrification-denitrification in a sequenced batch reactor (SBR). One of the impacts is the detrimental formation of nitrous oxide, and the other is the positive boosting of nitrifiers to the mainstream process through bioaugmentation. READ MORE

2. Enhancement of Volatile Fatty Acid Production from Dairy Wastewater
Abstract : Resource recovery from waste-streams is a highly promising approach to meet with urbanization and modernization consequences. Rapid human population growth, expanding industrialization and excessive consumption of resources lead to increasing demand for raw materials and energy sources, and an escalation of greenhouse gas emission.

3. Microbial biopolymer production from waste streams
Abstract : Burgeoning concerns on the adverse environmental impacts of fossil-derived products are propelling the pursuit of material production from sustainable resources. Resource recovery from waste is a key component of meeting the environmental sustainability agendas set by the United Nations. READ MORE

4. EVALUATION OF BIOLOGICAL STRATEGIES TO ENHANCE HYDROLYSIS DURING ANAEROBIC DIGESTION OF COMPLEX WASTE
Abstract : Anaerobic digestion (AD) offers considerable potential in the production of energy from renewable sources, and is being increasingly recognised as a sustainable technology for the treatment of waste. The production of energy from waste such as municipal solid waste (MSW), lipid-rich waste, and agricultural biomass and waste may play an important role in the production of renewable energy given the huge amounts of these types of waste generated annually.

5. Bioaugmentation for reduction of diffuse pesticide contamination : a bioprophylactic concept
Abstract : Pesticides and their residues frequently contaminate surface waters and groundwater so consequently there is a great need to identify methods and practices that reduce such contamination. This thesis examined the potential of a 'bioprophylactic' concept based on the hypothesis that diffuse contamination after application in the field can be significantly reduced if pesticides are degraded as rapidly as possible after the intended effect has been achieved.
