Analysis of Emissions from Multipurpose Stove using Charcoal and Firewood

Cooking using biomass fuels results in high levels of emissions (carbon monoxide CO and particulate matter (PM2.5) resulting into indoor air pollution which causes over 1.7 million deaths per year worldwide. Many women and children in 3rd world countries are exposed to high levels of indoor air pollution. The research examines quantitative levels and health effects of particulate matter and carbon monoxide levels emitted by charcoal in an indoor environment and compares it with firewood using the multipurpose stove.  


The procedures employed in this study can be divided into 3 categories. The water boiling test, CO and PM. Particulate matter and carbon monoxide levels were monitored for about 1.25 hour period. The particulate matter levels ranged from (25-180) ppm using the charcoal


Research provides evidence that indoor air pollution is a major health concern. In addition, the use of cleaner fuels (e.g. LPG, solar, kerosene or electricity) should be encouraged. Improved cooking stoves would reduce indoor air pollution, reduce major deforestation problems in Kenya, allocate time for women to participate in the commercial activities, and reduce the burden of morbidity among women and children.  Charcoal is a better fuel compared to firewood. Although charcoal and firewood are both relatively available and cheaper fuels, they have been associated with several health issues that can lead to complications with continuous use in households than are poorly ventilated. Options for switching to fuels that emit less greenhouse gases and particulate matter in rural and also urban households will be discussed.
