Overall, Toyola has had a positive impact on the local economy and created jobs. Toyola buys the ceramic core and metal parts locally, creating a strong local demand from ceramic and metal enterprises. This both creates jobs and keeps value-added earnings within Ghana. Components— including the clay core, metal handles, and metal grills—are produced in 15 enterprises throughout Ghana, employing about 17 clay workers and 100 metal workers.
The clay core: Made from local resources, the clay core creates no CO2 emissions from international shipping. Clay extraction, however, accelerates land degradation and soil erosion. Moreover, the clay must be baked at high temperatures and the ovens are fueled with significant amounts biomass, which results in CO2 emissions.
The metal component: Made with local scrap metal, and there are also no CO2 emissions from international shipping. However, the high demand for scrap metal has led to theft of metal objects such as manhole covers. Welding the metal to make the components is also highly energy-intensive and produces CO2 emissions.
Assembly: The stove elements are transported to one of eight assembly centres in Ghana. These centres employ a total of 30 people, and the staff generally works 9 to 12 hours a day and 6 days a week. Employees say they are treated well and that they are continually learning new skills. Safety is a concern for employees however, who worry about work-related injuries and the lack of first-aid kits and safety gear.
Reduced need for charcoal: Toyola’s energy-efficient cook stoves reduce the need for charcoal, which means less deforestation, less emissions, and more money saved by the end-user. Since there is less need for charcoal, end-users spend less time gathering wood or charcoal and have more time to attend to other needs. In general, end-users have been very happy with their stoves and use them daily. The only problem reported with the stove is that the clay core sometimes cracks during or after use. Bad road conditions during delivery can also lead to cracking.
