Cooking food with solid fuels such as wood, charcoal and coal is still very common in developing countries and communities that don’t have easy access to microwave ovens and electric burners like we do. And although it is a more natural option, according to the World Health Organization, up to 4.3 million women and children die each year by the direct and indirect effects of using such solid fuels.
This information called the attention of the Israeli company HomeBioGas, who improved existing technologies to create HomeBioGas TevaGas (TG), a family-sized bio-digester made to be a sustainable and safe solution to the issue. The anaerobic digester works on energy generated by organic material, such as food waste, which is converted into biogas fuel, a combination of methane gas and carbon dioxide. This fuel can be used for cooking or heating without generating unpleasant odors, and even the liquid left over after using the gas can be used as fertilizers for gardens and vegetable crops.
“The basic underlying principles of bio-digester are, well biological,” Marketing Director Ami Amir explains, “There are bacteria or microbes that thrive in conditions where there is no air (anaerobic) that are able to break down organic matter into their components. One of the results of this process is known as biogas, a combination of methane gas and carbon dioxide.”
HomeBioGas TG is the result of years of research on other existing bio-digesters in China and India. The Israeli team came to the conclusion that an entirely new model had to be developed. “The intention was to develop the best product that will provide biogas from waste for the under-served populations of Latin America, Africa and Asia,” says Amir. “In these communities, there is little or no means of waste disposal and hardly any connection to utilities.” The product was first tested in a Bedouin community in Israel and is now sold separately for US$2,500.
