is a brilliant off-grid system that generates clean energy without using any electricity and allows you to properly treat your household waste. The system produces as much as two to three hours of cooking gas every day by processing food scraps or animal waste.
The Homebiogas bioreactor comes in an easy-to-install DIY kit with all the tools and detailed instructions needed. Estimated setup time is about an hour. The bottom portion is filled with water and is activated with microbes from animal manure (ideally from cud-chewing animals such as cows, goats, sheep, deer, camels or buffalo) or, lacking that, from a special bacteria starter packet from the company. Heat from the sun helps the microbes inside grow, and once you have a healthy colony of bacteria in the digester (about two to four weeks), you’re ready to feed the system with food scraps.
Unlike a compost pile, you can put almost any organic matter into the system, including not just fruit and vegetable scraps (no citrus), but also meat, dairy, fats, bones, and even animal or human waste (the company is working on developing a “Bio Toilet”). No leaves, grass, or wood chips, though.
The bacteria eat the scraps, and the natural byproduct of this microbial action is methane gas, which is trapped in a holding tank on top. Tubing (also provided) pipes the biogas to a range burner in your kitchen. Simple! Use the gas for cooking, heating your home, or even running a generator.
As a bonus, the system produces liquid fertilizer you can use in your garden.
Generating biogas is actually an age-old technology. In fact, Marco Polo returned from China with tales of pipes coming out of underground dung heaps that supplied clean-burning gas. Bioreactors are small enough to fit into the smallest of backyards and are affordable, odorless and super simple to operate. Homebiogas also has built open-source (construction plans that are not proprietary or patented, so anyone can make one) , in refugee camps, prisons, cold climates, hot climates, cities and the country.
“Families should use HomeBiogas because it an amazing product to achieve a zero-waste home and also a great way to save money!”says Homebiogas user Amanda Naber.
Biogas user Orit Hazan says, “It’s a miracle —generating clean energy in your own home! For me, the food is more delicious when cooked with homemade biogas.”
Home bioreactors are the perfect solution for people trying to live sustainably, off-grid and with renewable resources. Unlike solar or wind technology, bioreactors can provide energy for running generators or supplying cooking gas even when the sun is down or the wind stops blowing.
