People waste a lot of food. According to the United Nations Environment Program, first world countries waste about 220 million tons of food per year.
And although reducing the amount of food that ends up in the garbage should be a goal for everyone, turning organic waste into fuel could reduce the amount that finds its way into landfills.
10 Crazy Crowdfunding Ideas That Worked!
A mere 1.6 gallons of food waste could create three hours of cooking gas, according to the folks who launched the HomeBioGas fundraising campaign on Indiegogo. Their prepackaged system arrives in a box and can be set up in any backyard in about two to three hours.
It contains a digester filled with special bacteria that like to eat organic waste. Just feed the top with food waste, dairy, meat and even litter box refuse and let the microbes do their thing. As they eat what you don't want, they produce methane gas that can be piped into the house - please use a licensed plumber - and right to your stove.
Because the contraption produces gas at a low pressure, the safety level is high and the risk for an explosion very low.
10 Simple Techs To Tackle World Problems
"Even if there is a leak, since methane is lighter than air, it immediately evaporates and gets dissipated in the atmosphere," Ami Amir told Gizmag.
The resulting by-product from the HomeBiogas system is a natural liquid fertilizer that users can pour on their garden to grow more food.
Even though the HomeBioGas system is relatively new to Indiegogo, several systems have already been installed in communities throughout the Middle East and Africa, where people living in poverty often cook using wood, charcoal or coal. These solid fuels create air pollution and according to the World Health Organization, kill more than 4 million women and children each year.

As of this posting, the Indiegogo campaign has exceeded its US$100,000 goal, but there is still time to reserve your own. Backers should receive their systems in May 2016.
