Biogas at Home

Biogas Digester

Commissioning a biodigester takes a bit of time and effort utilising 100 ltrs of fresh cow manure to get the digester started. You can also use fresh sheep, goat or Alpaca manure, and other manures like horse manure can also be used but will need added probiotic powder (available extra) to activate the digester.  Chicken manure is not recommended due to acidic nature.

Once gas is produced after 4 to 6 weeks (depending on temperature and how fresh the manure was) then you can start adding food waste - but hold off on acidic foods like citrus peels until the digester is at peak performance.

Biogas Bags

The 500/600 litre gas bags supplied (when full) over an hour of cooking time and the more you feed the digester with food waste, or more manure, the more gas it will produce for your cooking needs.

Our family of 3 adults (including granddad) and two children produce about 3, buckets of food waste a week which provides all the gas we need for cooking for the whole family. When adding food waste to the digester, add the same volume with fresh water and chop or macerate the contents as much as possible to speed up gas production - the anaerobic bacteria prefer small particles to eat rather than large... Methane is their by-product, which provides us with a cyclic process where 'waste' is converted to energy - and in Nature there is no such thing as waste, so we are emulating Nature.
