Alternatively, dung can be used for producing biogas or burnt in gasifier cookstoves. Biogas provides an option to create a much cleaner household cooking fuel, but its generation is much more complex and depends on the availability of water. For further information, please read the articles on cooking with biogas and on biogas stoves. Quite recently developed gasifier cookstoves [LF3] are getting more and more attention as they are very clean burning stoves.

As a result, a high quantity of ash remains in the stove at the end of a dung-fire. Considering that burning dung is often the only available energy source for households in some regions, this practice should be prevented wherever other suitable options are available and applicable, due to the following reasons:. It is basically based on experiences, lessons learned and information gathered by GIZ cook stove projects.

Results Incubation of the dung cake particle suspensions in the RTLF for 4 h resulted in a mean loss of ascorbate of Conclusion These data demonstrate that biomass derived particles have considerable oxidative activity, largely attributable to their transition metal content. Background Approximately two billion people in the developing world use biomass fuels such as wood, crop-waste and dried animal dung, as their major source of domestic energy [ 1 , 2 ].
Results Three Teflon filters were supplied containing 0. Open in a separate window. Figure 1. Figure 2. Figure 3. Figure 4. Figure 5. Discussion Indoor air pollution poses a significant health risk worldwide. Conclusion These data demonstrate that fine particles derived from the burning of the biomass fuel dung cake are highly oxidising. Hexane extractions 1 ml of each dung cake particle suspension at Statistical analysis All data are expressed throughout as means with SD.

When people burn dung cakes, over 25 per cent of the arsenic in fumes could be absorbed by the respiratory tract and this leads to lung cancer and other diseases. But there are solutions to this problem. One of them is the construction of gobar gas plants. The government offers a huge subsidy for gobar gas plant construction, but there is a lack of commitment in implementing the scheme.
