Renewable energy is shifting from the fringe to the mainstream of sustainable development. In Africa, this is primarily due to an abundance of renewable energy sources and characteristics specific to remote rural communities that make fossil fuel based energy systems extremely expensive. It has been argued that jatropha oil, a renewable energy source, currently being promoted in some African countries can be a suitable substitute for diesel. This paper examines the physico-chemical properties of Jatropha oil that makes it a cleaner and locally available diesel fuel substitute. It assesses the potential impacts of the biofuel on the rural economy and presents a development model for a sustained biofuel enterprise aimed at rural economic empowerment in drought prone rural African communities.

Because of their importance with respect to the materials used, a life cycle assessment has been performed, to identify and quantify energy, material used and wastes released to the environment. In this report, data collections of raw materials, manufacturing processes, and end-of-life of products were accumulated step by step based on self-developed checklists. The manufacturing process is complex and composed of several unit operations, a product inventory cannot be optimally determined by simple measures. Therefore, this study is based specifically on its own system boundaries and hypotheses. The interpretation of the environmental impact was displayed, by the used of Life Cycle Assessment (LCA) software tool, in terms of impact categories such as greenhouse effect, acidification, eutrophication etc., thus environmental conclusions can then be drawn from the study.}, language = {en} } @article{MittelstaedtErtelHanke, author = {Mittelst{\"a}dt, Mandy and Ertel, J{\"u}rgen and Hanke, Andr{\´e}}, title = {Start frei f{\"u}r {\"O}kochips: Teil 2: Schadstoffanalyse bei DRAM-Modulen}, language = {de} } @misc{AckomErtel, author = {Ackom, Emmanuel Kofi and Ertel, J{\"u}rgen}, title = {An Alternative Energy Approch to Combating Desertification and Promotion of Sustainable Development in Drought Regions}, series = {Forum der Forschung}, journal = {Forum der Forschung}, number = {18}, issn = {0947-6989}, pages = {74 -- 77}, language = {de} } @article{AlemagiErtelOben, author = {Alemagi, Dieudonne and Ertel, J{\"u}rgen and Oben, P.
