What Can You Put into HomeBiogas?

HomeBiogas can be fed food scraps, animal manure and even human waste!

You can feed your HomeBiogas system approximately 6 liters of food waste OR up to 15 liters of animal waste daily mixed with double that amount of water.

Do Put Kitchen Waste

The appliance thrives on all types of food leftovers; meat, dairy, vegetables, fats, bones, pits, seeds and egg shells. You can put in rotten or moldy food as well. Avoid feeding large quantities of citrus fruit (orange, grapefruit, lemon) skin since it contains anti-bacterial oil, which could reduce the effectiveness of the digestion.

Do Put Animal Manure 

You can feed the appliance with animal manure, especially that of any animal that chews its cud (i.e. cows, deer, camels, buffalo, goats and sheep). The animal manure should be free of stones, straw, and earth, which will not break down in the digester. You may also add dog or cat waste (without sand). We recommend limiting chicken droppings, since they contain a high level of ammonia and will alter the balance of the digester fluid. 

Do Put Human Waste

Those who choose to put human waste into HomeBiogas should use the 2.0 model in conjunction with the Bio Toilet. Human waste will break down and be turned into biogas just as animal manure would.

Don't Feed Too Much Of These Things

-Not too much chicken feces (up to 50%)  
-Not too much fats, oils, grease (up to 25-30%)  
-Not too much citrus fruit (up to 2 citrus fruit peels a day)
-Not too much roots, stalks  
-Not too much compostable diapers (1 per day, depending on brand)
-Not too much tissues 

Do Not Feed

The following items will not break down or will break down slowly, clogging the digester: feathers, paper, cardboard, fur, coffee grounds, bleach, garden clippings, sawdust,  wood chips, straw, chewing gum, nail clippings, lint, hair, soil, sand, "Biobags" for dog poo/produce, any shells, even shells from clams and oyster.
