The HOMEBIOGAS household biogas system turns organic waste like food scraps and animal manure into biogas, which can be used for cooking, and natural liquid fertilizer, which can be used for gardening. Biogas is generated in the system by the anaerobic (without oxygen) fermentation of organic matter. Biogas is a ammable gas that is lighter than air, composed mainly of methane and carbon dioxide.

activating the system Wait a day after assembly and verify there are no leaks before starting activation. Activate the system in warm weather. (average day/night temperature at least 25 °C (77 °F) for the rst 4 weeks). To activate, you will need: 100 liters (25 gallons) of animal manure from herbivores, fresh (wet and up to 2 days old) & clean as possible from straw/stones/earth.

Agitate the digester tank around the inlet sink area Once weekly, agitate or ‘massage’ the top part of the digester tank, all around the front (inlet sink) side of the digester. The agitation process improves digestion e ciency and helps move solids towards the back of the tank.

The fertilizer is essentially the discharge from the digester tank. This discharge, the result of a long digestion process, is packed with various microbes, biostimulates, and organic nu- trients in the right form for rapid absorption by plants. The presence of both macro & micronutrients makes HomeBiogas fertilizer a good choice for most gardening and small-scale agricultural purposes.
