An Israeli start-up has developed HomeBiogas, a system for converting leftovers into household gas for the home and liquid natural fertiliser for the garden.
At first glance, one may wonder what possible use this mysterious object vaguely resembling an inflatable tent with a black plastic chimney on top could have. Appearances can be deceiving: under its crude appearance, HomeBiogas is a proper gas plant, a smart digester for private individuals. The only prerequisite for owning one is having a garden and living in a temperate zone in which the average annual day/night temperatures are above 15 or even 20 degrees for optimal use.
2 kilos of waste = 2 hours of cooking time
All this requires is placing the food waste (vegetable peels, dairy products, meat fats and bones, etc.) or manure in the lower part of the device – the digestion chamber – and waiting. The digestion chamber is entirely filled with water, making it an anaerobic environment (without oxygen) that promotes the formation of microorganisms that will break down the organic matter and convert it into biogas. The gas is stored in the upper pocket, which is connected to the cooker through a pipe enabling the gas produced to be instantly used for cooking. According to its creators, two kilos of waste can produce two hours’ worth of gas. And as the device has an internal 700 litre tank, a considerable amount of biomethane can be stored inside it for later use.
Better yet, this super composter also produces liquid fertiliser ideal for feeding gardens, orchards and vegetable gardens!
A 100% circular innovation
There are two advantages to owning this device which is able to digest any organic waste, unlike other composters: reducing waste while creating renewable energy for the home! It can eliminate 1 tonne of organic waste per year, and reduces its users’ CO2 emissions by 6 tonnes per year.
Made from polyethylene (PE), polypropylene (PP), PVC and ABS, and resistant to UV rays, the HomeBiogas can be assembled in under two hours and its flexible and lightweight structure enables it to be delivered as an ordinary package. This affordable device is currently available in 90 countries. The Israeli start-up hopes to expand its market by targeting emerging countries in which access to energy is limited, as well as developed countries that have begun their energy transition.
“We are a socially responsible company”, explains Oshik Efrati, CEO and co-founder of HomeBiogas: “our initial campaign enabled environmentally-conscious Western consumers to reduce their greenhouse gas emissions and start using renewable energies at home. We believe that with a new campaign and its low price, HomeBiogas 2.0 will have an even greater impact on communities around the world, whether in the United States, the Philippines or Senegal.”
