Great invention turns waste into energy for cooking

While every second has passed, there are tons of leftover food left over, but if recycled they can save you a lot of costs for cooking.

The biogas cellar , also known as biogas , is not strange to Vietnam, especially in rural areas. But in rural areas, with waste from livestock activities of households, has helped to bring in a rich source of inputs for these biogas plants. The biogas produced from these tunnels can be used as a clean fuel source like conventional gas, which saves fuel costs as well as limits unpleasant odors generated from waste.

Although biogas has many benefits, another source of material that can produce this biogas is being wasted every day. It is a source of raw materials and organic waste, which are always discarded instead of recycled into useful products.

This system is able to assemble and with dimensions of only 165 x 100 x 127cm (Length x Width x Height).

However, HomeBiogas company, based in Beit Yanai, Israel has created a system to help utilize excess food and organic waste to turn it into clean cooking gas, in addition to the by-product of the system. This can also be used as a liquid fertilizer for plants. Not only that, the most interesting thing about this system is that it can be assembled and is only 165 x 100 x 127cm (Length x Width x Height), it can fit right in your yard.

The input of this biogas system could be all kinds of organic waste , including meat, milk and even cat litter. Once inside, the anaerobic bacteria in the fermentation cell will decompose organic materials and release biogas.

The generated biogas will be removed from unpleasant odors and toxic gases such as hydrogen sulfide H ₂ S, which will then be connected to the gas pipe to the stove. Liquid fertilizer will be liquid by flowing through a chlorine plate to reduce the number of active bacteria and can be collected to fertilize the plant.

The input of this biogas system may be all kinds of organic waste.

Costing up to 995 USD and without electricity, HomeBiogas system can handle up to 5kg of uneaten feed or 15 liters of animal manure every day. The amount of gas generated by the system every day is equivalent to 6 kW of electricity.

"Under normal conditions, this amount of gas is enough for three hours of cooking." Mr. Ami Amir, who is in charge of marketing and business development for HomeBiogas, told Waste 360. "The system is acceptable for meat, fish, fat, oil and dairy foods - all things can't solved by conventional incubation ".

With three hours of cooking each day, usually you can save money equivalent to the cost of a 12kg gas tank. So with the condition in Vietnam, you can only take 5 or 6 years to recover the initial capital when investing in a system like HomeBiogas.
