Assessing the sustainability of bioethanol production in different development contexts: A systems approach
The continuous depletion of fossil fuel reserves, the global agenda on climate change and threats to energy security have led to increased global interest in the exploration, production and utilisation of bioenergy and biofuels. Access to modern bioenergy carriers derived from the efficient conversion of locally available biomass resources is indispensable for economic growth, rural development and sustainable development in developing countries. Deployment of bioenergy/biofuels technologies has significantly varied across the globe. The least developed countries (LDCs) and developing countries are still highly dependent on traditional biomass technologies with low conversion efficiency, which are typically associated with significant environmental and health impacts. Meanwhile, emerging economies and developed countries are progressively promoting biofuel industries and international trade. They are also engaged in making biofuels a sustainable proposition by developing sustainability criteria. The goal of this thesis is to address the sustainability of bioethanol production derived from one of the key feedstocks/energy crops: sugarcane. This will be done by analysing different development contexts and environmental constraints in terms of geopolitical situation, economic development and state-of-the-art technologies in agro-industrial development. Life cycle assessment (LCA), system studies, and techno-economic optimisation are the main methodological approaches applied in the thesis. The thesis primarily addresses three key questions for analysing the sustainability of bioethanol production. The first research question investigates the key parameters affecting the sustainability of bioethanol production and use in a low-income country using the case of Nepal. The net energy and greenhouse gas (GHG) balances are identified to be the main sustainability criteria of the sugarcane-molasses bioethanol (Paper I and II). Results of the lifecycle studies show that the production of bioethanol is energy-efficient in ...
