HomeBiogas units perform anaerobic digestions. Anaerobic digestion is the breakdown of organic material by micro-organisms in the absence of oxygen. It produces biogas, a methane-rich gas that also contains carbon dioxide with trace amounts of other gases; and digestate, a source of nutrients that can be used as a fertilizer. The digestion process begins with bacterial hydrolysis of the input material in order to break organic polymers into smaller molecules that finally become methane and carbon dioxide after acidogenesis and methanogenesis.

Use:

• Installation: it takes two people about 2 hours to install HomeBiogas. Anyone can assemble the biogas unit. However, connecting HomeBiogas’s gas pipe to the stove should be done by a licensed gas technician. Detailed instructions are provided with the system.
• After installation: HomeBiogas may take between 2-4 weeks to produce gas. Then as long as you feed the system, it will continue to produce gas.
• Water added to the waste: Initially, fill the tank with water to its full capacity (about 650 liter). Once HomeBiogas is in operation, remember to add one liter of water for every liter of waste added.
• Nominal gas pressure: 15 millibar
• Temperature: Above 17 °C (66 °F) for consistent gas production
• Per day, up to 6 L of food waste or up to 15 L of animal manure can be digested.

Technical support is provided by HomeBiogas, however, HomeBiogas recommends hiring a licensed gas technician to connect the system’s gas pipe to the home kitchen stove.

Expected lifetime of the unit is unknown, although the unit includes a 12 month limited parts and materials warranty.

Maintenance: HomeBiogas recommends maintaining the HomeBiogas unit once a year by: 1. Replacing its gas filter (takes a minute to do and filter cost about $20). 2. Removing the sludge that accumulates at the bottom of the digestion tank via the outlet pipe.

Extreme caution is necessary when working with biogas. Adequate ventilation, appropriate precautions, good work practices, and adequate personal protective equipment will minimize the dangers associated with biogas.
