Attached is my BINGKA OVEN fired by an Eco-Kalan-C using charcoal (oling) made from coconut shells. I have used charcoal as fuel as it burns clean. I have used firewood also but the soot that is formed inside the oven tarnishes the looks of whatever is baked in it. In the Philippines, there are many men and women who use the traditional “hornohan” for their home-based businesses of making bingka (sweet rice cake with coconut), tortas (breads filled or plain) and cakes made of cassava, ube, wheat and sweet rice. In most cases, one does not earn enough to pay for the medical costs of treating illnesses such as cancer, eye and skin infections and lung diseases which result from long term exposure to smoke and intense heat. By reducing fuel consumption and exposure to radiant heat and by removing the smoke from the cooking environment and immediate neighbourhood, the BINGKA OVEN can bring better health and higher living standards to poor families in the Philippines.
