Abstract
This thesis assesses the feasibility of implementing Clean Development Mechanism (CDM) activities that convert Tanzania’s substantial sisal waste streams into biogas and electricity. The work is motivated by the country’s limited CDM participation despite high potential and by climate impacts from methane released as sisal waste decays in a rapidly growing industry. Using established models, methodologies, and tools, the study quantifies baseline methane emissions from disposal sites, estimates biogas and power generation potentials, and evaluates additional emission reductions from displacing fossil-based grid electricity with biogas-derived electricity. It also examines CDM criteria such as additionality and sustainable development impacts, conducts financial analyses (NPV and IRR), and identifies risks through methodological and strategic assessments. Findings indicate that utilizing sisal waste for biogas can substantially cut greenhouse gas emissions and supply electricity to the grid, and that the proposed project can meet key CDM requirements. Successful implementation, however, depends on addressing risks related to baseline and monitoring methodologies, biogas technology performance, financing conditions, and uncertainty beyond the Kyoto commitment period.
Dette speciale undersøger muligheden for at gennemføre Clean Development Mechanism (CDM)-aktiviteter baseret på omdannelse af Tanzanias betydelige mængder af sisalaffald til biogas og elektricitet. Baggrunden er landets lave CDM-deltagelse trods store potentialer samt de klimamæssige konsekvenser af metanudslip fra nedbrydende affald, i en sektor der forventes at vokse. Specialet anvender anerkendte modeller, metoder og værktøjer til at beregne baseline-metanudledninger fra affaldsdeponier, estimere biogas- og elproduktionspotentialer og vurdere yderligere udledningsreduktioner ved at erstatte fossilt baseret netelektricitet med el fra biogas. Der gennemføres vurderinger af CDM-kriterier som additionalitet og bæredygtig udvikling samt finansielle analyser (NPV og IRR), og der identificeres risici gennem metodiske og strategiske vurderinger. Resultaterne viser, at udnyttelse af sisalaffald til biogas kan reducere drivhusgasudledninger markant og levere el til nettet, og at det foreslåede projekt kan opfylde centrale CDM-krav. Gennemførelse afhænger dog af håndtering af risici knyttet til baseline- og monitoreringsmetoder, biogasteknologiens ydeevne, finansiering og usikkerhed efter Kyoto-perioden.
