Wonderbag is a simple but revolutionary non-electric heat-retention cooker. It continues to cook food that has been brought to boil by conventional methods for up to 12 hours without the use of additional fuel. Wonderbag is part of Natural Balance South Africa and forms partnerships with companies looking to reduce CO2 emissions, while alleviating poverty and creating employment. Wonderbag helps companies to meet their Corporate Social Responsibilities and environmental ambitions. For every Wonderbag sold a portion of the proceeds goes towards donating a Wonderbag, via The Wonderbag Foundation, to a family in need within a designated community in a developing country.
