HomeBioGas™

The Agricultural Department, EPA and some business groups began a "Food Waste Challenge" to find ways to reduce the amount of food filling our landfills. Cities around the nation are meeting the challenge by recycling organic material. Food waste and yard trimmings are turned into compost and biofuel and then sold back to the community. Recycling organic waste reduce the pollutants entering our groundwater and the methane emissions that contribute to global warming. The compost helps future plants grow and the biogas can generate new energy.

An Israeli start-up company, HomeBioGas™, has a workable small scale solution. Their self contained unit is a clean, safe way to achieve these benefits for households and small communities, especially ones “off the grid”. The pressurized gas generated is ideal for cooking.

This from their website:

HomeBioGas™ offers the most advanced, compact and cost-effective anaerobic digesters that convert kitchen waste and animal manure into cooking gas and liquid fertilizer, while maintaining highest safety and health standards.

Cooking and heating with Biogas reduces deaths and respiratory diseases of women and children who previously had to rely on kerosene and wood fires. Cutting down trees for firewood reduces the amount of CO2 absorbed by trees and increases land erosion. Soil run-off pollutes rivers and lakes.

TevaGas™, a new class of HomeBiogas Anaerobic Digester for “off the grid” families, treats both food waste and animal manure. TevaGas provides clean Biogas for cooking 3 meals a day, for heating and as a light source; and 10 liters of organic clean liquid fertilizer per day,.increasing the yield of the family’s vegetable and fruit garden.

  • Sealed – Cover prevents odors and presence of insects and mosquitoes;
  • Above Ground – No need for digging and heavy construction;
  • User Friendly Interface – Dual purpose sink for manure or kitchen waste feeding, built-in food waste grinder, optional water tap;
  • Gas Pressure – Patented gas pressure system delivers continuous gas under pressure.

Main Features

  • Manual Grinder - The only home scale biogas system with built-in food grinder, improving digesting efficiency by up to 300%;
  • Pressurized Gas – The only biodigester with a patented, integrated, controlled gas pressure mechanism;
  • Hydroponic Bio-Filter - Built-in filter improves liquid fertilizer quality:
  • Dual function Sink – Special built-in food waste inlet and a convenient wide chamber for animal manure;
  • Gas Filter – The only systems with a built-in filter, removes H2S and water from the Biogas;
  • Sludge Outlet – Convenient operational outlet for periodic sludge removal.

This is something I've thought about. There are already composting toilets for human waste. My research has shown me that earthworms used in the composting process remove pathogens, making the compost safe for vegetable gardens. It is called “Humanure” and is worth exploring.

"Nearly a third of all household drinking water in the US is used to flush toilets" -- Joseph Jenkins, "The Humanure Handbook"

"The function of all organic matter, animal and vegetable, is to maintain the fertility of the soil" -- J.C. Wylie, "The Wastes of Civilization"
