img_6380image-for-researchBangladesh Council of Scientific and Industrial Research (BCSIR) begun research to develop modern cooking stove in 1980. After research they create different models cooking stove for saving fuel, keeping kitchen smoke and pollution free and protecting users from smoke related diseases. But unfortunately this initiative failed and stopped in 1990. In December, 2005 GIZ (German Development Co-operation) started promotion of Improved Cook Stoves (ICS) using the clay stove model developed by IFRD (Institute of Fuel Research and Development) of BCSIR. But monitoring showed that the quality of stoves was not always according to design standareds. To overcome the quality problem GIZ introduced concrete as the material of manufacturing ICS in 2010. GIZ tested the efficiency of Bondhu Chula by ‘Institute of Energy’ of ‘University of Dhaka’. According to their analysis the efficiency of the Domestic Cooking Stove were 21.2%, 24.2% and 24.4% of 8 inch, 9 inch and 10 inch model Bondhu Chula. Where the efficiency of traditional stove is 10%-15%. Bangladesh Bondhu Foundation, GIZ strictly maintain the scientific design, shape and size of ICS. BBF has a Research Centre which always engaged to maintain the scientific design of ICS and trying to develop the design for increasing efficiency.
