1. Biogas Production from Citrus Wastes and Chicken Feather : Pretreatment and Co-digestion
Sammanfattning : Anaerobic digestion is a sustainable and economically feasible waste management technology, which lowers the emission of greenhouse gases (GHGs), decreases the soil and water pollution, and reduces the dependence on fossil fuels. The present thesis investigates the anaerobic digestion of waste from food-processing industries, including citrus wastes (CWs) from juice processing and chicken feather from poultry slaughterhouses.

2. Digestion and absorption of galactolipids
Sammanfattning : Galactolipids: digalactosyldiglyceride (DGalDG), monogalactosyldiglyceride (MGalDG) and sulfoquinovosyldiglyceride (SQDG) are the major lipid components in thylakoid membranes of chloroplasts i.e. the site of photosynthesis in plants. LÄS MER
3. Biogas Production from Lignocelluloses : Pretreatment, Substrate Characterization, Co-digestion and Economic Evaluation
Sammanfattning : Biogas production from organic materials can be used as a renewable vehicle fuel, provide heat and generate electricity and can thereby reduce the greenhouse gas emissions. This thesis focuses on the biogas production based on lignocelluloses. There is an abundant availability of lignocelluloses, constituting 50% of the total biomass worldwide. LÄS MER
4. Anaerobic Digestion – Microbial Ecology, Improved Operational Design and Process Monitoring
Sammanfattning : The implementation of anaerobic digestion is important in the concept of sustainable development, especially regarding the environmental benefits. Biogas is produced when organic matter is degraded by microorganisms under oxygen-free (anaerobic) conditions. LÄS MER
5. 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
