Abstract

The utilization of dried dung as fuel for household cooking stoves is very common in rural areas of developing countries. The objective of this study was to compare the environmental impacts for the provision of cooking heat from biogas with the utilization of dung cakes. For this purpose, the method of life cycle assessment was used for assessing the impact categories global warming potential, acidification potential, eutrophication potential and human toxicity potential. The results show that anaerobic digestion at household scale can contribute to the reduction of greenhouse gases (GHG’s) as well as several other emissions in rural areas.
