Provide a promising and inexpensive alternative for use in ICSs. Metal oxides, which have been shown to reduce diesel soot emissions, These noble metal catalysts are prohibitively expensive for use in Typically, noble metal oxidation catalysts (e.g., platinum, palladium,Īnd rhodium) are used to reduce vehicle exhaust emissions however, To the technology path taken in the 1970s to reduce automotive emissions. Improvement in stove emissions beyond what has already been achievedīy ICSs could be realized by integrating oxidation catalysts, similar (WHO), further improvements to ICS designs are needed. To meet emissions guidelines established by the World Health 5− 10 However, most households that adopt an ICS still have twice the

4 Early work showed that small design changes can drastically alter ICSs have been proven effective at improving indoor air qualityĪnd have been studied extensively since 1968. The development of improved cookstoves (ICSs), distribution of cleanerįuels (e.g., kerosene or liquid gas propane), and adoption of electric/solarĬooking.

(1) developing clean burning technologies and (2) successful adoption Reducing indoor air pollutants requires a two-pronged Respiratory diseases are the leading cause of death. 2 For instance, in Guatemala, where biomass is a common fuel, Indoor air pollutants specifically lead to an increase in chronicīronchitis, respiratory infections, and pneumonia. 1 Women and children, typically present duringįood preparation, are disproportionally affected by indoor air pollutants. Harming individual health, local air quality, and global climate change.īurning biomass releases large amounts of particulate matter (PM 2.5) that is responsible for 2.8 million deaths annually. Although renewable, biomass combustion is incomplete, Identified strengths and weaknesses of the stove that are being addressedĢ.5 billion people use biomass as their primary cookingĪnd heating fuel. An additional qualitative portion of the field study The stove reduced emissions by as much as 68% and improved fuel efficiencyīy as much as 61% during real-world cooking events relative to the Guatemala, where users cooked 93% of the time with the catalytic stoveĭespite having to change some cooking practices. The field trial demonstrated a high level of user acceptance in rural To ensure that stoves were operated correctly. Field trial participants were provided with stove training Usingįocus group results, the stove was tailored to the needs of GuatemalanĬooks. Levels to cause respiratory illnesses and other health problems. Stoves often emit particulate matter and carbon monoxide at sufficient Improve efficiency compared to open cooking fires or traditional semienclosedĬookstoves, called poyos, typical of rural Guatemala. Rocket stove was developed to reduce emissions and
