Life cycle approach for evaluating sanitation projects - case study: biogas latrine

This paper applies a Life Cycle Assessment framework for the evaluation of water and sanitation projects to a biogas latrine constructed in Uganda. This will be the first time this assessment tool is applied to a sanitation project in the East African Region. While using this tool, one takes into consideration five life stages of a development project and five sustainability factors (socio cultural respect, community participation, political cohesion, economic sustainability, and environmental sustainability). By using this tool during planning, implementation and evaluation of a project, the sustainability of a project can be increased and lessons can be learned and implemented in similar future projects. In this case study the tool was used to evaluate the biogas project and create a starting point to rehabilitate the system.
