The appliance will begin to produce gas 1-3 weeks after the initial activation using animal manure. (Read more about first time set-up here). After this initial gas, the bacteria inside of the system will work 24/7 to break down waste and produce gas, just like our stomachs do, so long as it is warm enough. (Read more about optimal climates here).

How quickly your food will break down and convert into biogas depends on various factors such as what type of waste you feed and the temperature outside. Different foods have different amounts of energy that will become available when the food is digested (either by your body or by a biodigestor).

Still, we have found that as a general rule: 1 kilo of organic waste = 1 hour of cooking gas.
