Usage of inefficient and unsafe cookstoves is a cause of significant health losses and injuries in low-income communities. Efforts to develop and disseminate clean cookstoves have concentrated on optimizing thermal and emission performance, but minimal attention was given to safety aspects. Discussions conducted by the ISO TC285 Technical Committee...

Coal not only powers the household, social and global economy development but also emits large pollutants. Natural gas and electricity can be promising solutions to the energy supply and environmental pollution dilemma in Hebei Province of China. Currently, this coal‐dependent province has launched the Hebei Air Pollution Prevention and Control Pro...

Direct combustion of solid biomass fuel is one of the most common energy sources in developing countries. Evaluation of technology for household biomass pellet fuel combustion is critical, since promoting poorly designed devices may have risks due to exposure to high levels of emissions. This study evaluated the effects of various testing condition...

Charcoal stove is widely used in the developing countries especially in Africa and Central America. Even reported to have a high impact on human health, stoves promoted in the related areas still mainly focus on fuel saving and little knowledge was reported for the stove performance in the field. This research evaluated four commercialized charcoal...

Indoor air pollution is ranked the 5th in the Global Burden of Disease index of the World Health Organization (WHO). Almost half of the world’s population depends on biomass fuels to meet their basic energy requirements for cooking, lighting and space heating. When fuel is badly combusted in poorly designed stoves, the fuel-stove combination result...

Biomass is a sustainable and renewable energy source with relatively low pollution emissions. It can be transformed into gaseous, liquid and/or solid biofuels as well as other raw chemical materials and products. Among the biomass conversion technologies, densified solid biofuel is one of the means that is storable and transportable with low heatin...

Inventory analysis of greenhouse gas emission for large-scale biogas plants using carbon footprint method still needs to be improved. Based on the life cycle theory, the application of carbon footprint on four large-scale biogas plants was analyzed in this paper, which comprehensively considered project progresses of civil engineering construction,...

In this study, different ways of testing household biomass cooking stoves are compared and analyzed. The differences between test methods relate to the stove operation and data analysis methods, the fueling procedure, the end point selection, the choice of metrics and others factors. The influences of these differences were analyzed by using an ind...
