Israel: Home device turns trash into biogas

HomeBioGas’s TevaGas (TG) device is the first family-sized digester made available on the market, which, according to Marketing Director Ami Amir, “is as easy to use as a dish-washer.”

The World Health Organization reports that up to four million people die from the direct and indirect effects of cooking with solid fuels, like wood, charcoal and coal. This staggering statistic hadn’t come to the attention of the Israeli inventors of the HomeBioGas system, until the information was pointed out to them by none other than United Nations Secretary General Ban Ki-moon. During a visit with Israeli President Reuben Rivlin last year, Ban expressed the global need for a sustainable and safe solution to this dire issue, naming Israel’s HomeBioGas’s digester as a very viable answer.

“The basic underlying principles of a digester are, well biological,” 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”. By feeding the remains of their dinner , or any organic trash for that matter, into the digester, users are able to generate clean, renewable biogas to cook three meals a day. In addition, the remaining soluble chemicals left over from the biogas breakdown process (about 10 liters according to the company) can be used as liquid fertilizers for gardens and vegetable crops, a very useful addition for agriculturalists and sustainable farmers.

“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. Of course, before releasing their product to the world-at-large, the team wanted to test it out at home, which is why the first functional models of the system were introduced to a Bedouin community in Israel’s Negev Desert. Amir explains: “In these communities, there is little or no means of waste disposal and hardly any connection to utilities.” Since the company serves mainly under-resourced communities, many of its clients don’t have the funds to support the shipment of the product. This means the company needs to rely on hefty subsidies from governments and non-governmental organizations, which can be hard to come by. Yet due to a surge in awareness of environmental issues, like recycling, composting and homebiogas-ing, the company is even earning some support in developed countries like the United States, Australia and some European countries, who want the system for their own homes.
