An Israel company, HomeBiogas has taken sustainability to a new level. They have created a portable system that transforms food waste into cooking gas and fertilizer. The system works by using bacteria to breakdown food scraps, which can be almost anything fruits, vegetables, and even meats. As the bacteria breaks down the food it produces biogas that’s collected at the top of the system, the system is able to store 700 liters of biogas. The biogas can be used for cooking, hot water, and electricity generation. Another byproduct of the process is a liquid fertilizer which can be used in the garden.
According to the company, an average family’s daily food waste is enough to produce 2-3 hours worth of biogas. With an estimated 1 billion pounds of food wasted or lost every year, this is an amazing alternative with great benefits.
