This study assesses the technical, economic, and environmental assessment of a developed improved cookstove (ICS) for domestic uses focusing on outperforming the traditional charcoal cookstove by improving technical performance, fuel economy, and environmental savings. A set of experiments were conducted to verify the performance of the ICS. The technical performance involved measuring the cooking time (tc), maximum cooking temperature (Tmax), fuel consumption (fcons), thermal efficiency (ηth), and cooling time (tcool). The economic assessment involved daily and annual fuel cost, and daily and annual fuel cost saving while environmental saving involved annual reduction of CO, CO2, NO, and NOx gases. The Tmax of the ICS reached 1273 K, reducing the tc by 18 mins, a drop of 43%. Furthermore, this reduced the fcons by approximately 50 g, around 30%. The ICS had an enhanced tcool of about 24.53 mins and attained ηth of 43.3%. In five tests, the ICS consumed about 596 g, which costs TZS 870 and TZS 317,550 per year. The reduction in consumption significantly reduces fuel costs by 29.83%. The results showed the ICS reduced the emission of CO, CO2, NO, and NOx concentrations by 258, 650, 2, and 2.5 ppm, respectively, compared to a traditional charcoal cookstove.
