Talk about cooking with gas.
HomeBiogas, based in Beit Yanai, Israel, is a biogas system that turns food and organic waste into clean cooking gas, and its byproduct can be used as liquid plant fertilizer. Best part? It easy to assemble and can be placed in your own backyard.
You can place all kinds of organic waste including meat, dairy and even used kitty litter into the system. Once inside, bacteria inside the digester will decompose the organic material and release biogas.
