Researchers Discover Higher Environmental Impact from Cookstove Emissions
Cookstoves are a central part of millions of homes throughout Asia: families often use readily available and cheap biofuels—such as crop chaff or dung—to prepare the food needed to survive. Previously, numerous research groups worldwide have shown, mostly based on laboratory experiments, that smoke emitted from stoves used for both cooking and heating have a definite, detrimental environmental impact, particularly in India. Despite advances in technology, many people are reluctant or unable to adopt the newer, cleaner cookstoves. For several years, a collaborative team from Washington University in St. Louis has studied the issue and potential solutions. Now, new research gives them a clearer picture of the topic’s true scope.
The research was the culmination of field studies conducted in India by faculty members at Washington University’s School of Engineering and Applied Science and the Brown School. “We went...
