Read MoreHomeBiogas 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 20 liters of animal waste daily. An equal amount of water should be added with the waste when you put it into the inlet of HomeBiogas.
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.
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.
Those who choose to put human waste into HomeBiogas should use the 2.0 model in conjunction with the Bio Toilet. Human waste and toilet paper will break down and be turned into biogas just as animal manure would.
-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
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.
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.
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).
In general, food waste has a higher energy-generating potential because it has not yet been digested by the stomach of an animal. For food waste, fats, oils, and greases (FOGs) are especially productive, though not recommended in large quantities. But overall, feedstock high in calories, fat, starch, and sugar usually produces more biogas than other foods.
• High biogas yield: bread, corn, peas
• Low biogas yield: fish, poultry, water, spinach Still, we have found that as a general rule: 1 kilo of organic waste = 1 hour of cooking gas.
Biogas with Animal Manure Biogas yields from highest to lowest:
Dog, cat, and human waste also work to produce biogas but are limited in comparison to the amount that livestock manure can produce.
*Although poultry manure has a high biogas potential, it is hardly utilized for biogas production because it contains large amounts of ammonia. Its effective utilization as a biodigester feedstock requires that it go through an ammonia stripping process.

Read MoreMost people take hot water, indoor plumbing, and flushing toilets for granted, but things aren’t always that easy. Outside centralized sewers, managing waste and wastewater can be a challenge all year round, and having the right equipment can become a game-changer for homeowners. Off-grid toilets and sanitation systems make waste management easier while providing comfort and sustainable solutions. You can pick from multiple systems, from flush toilets to compost toilets to waterless toilets. This blog post will tell you everything you need to know to make an educated decision for your homestead.
Read MoreWhen a household can’t connect to sewage or wishes to live sustainably, composting toilets (or compost toilets) offer homes sustainable, environmentally friendly solutions to human waste management. But selecting the ideal product isn't always straightforward. A bit of research is needed before buying the best composting toilet for your home, and this blog post can help you get started.
Read MoreRenewable natural gas is improved biogas that can substitute natural gas with a significantly lower environmental impact. It’s obtained from organic waste, whether it comes from municipal solid waste landfills, wastewater treatment plants, livestock farms, food production facilities, or other organic waste management operations.
Read MoreAfter two years of Covid, the hotels are experiencing a revival and all of us are already fantasizing about a pampering vacation that includes tanning at the poolside and a rich buffet. But what happens to all the food that is left in the buffet after we're done piling it up on our plates? The hotel industry is responsible for 37% of the food waste in Israel, this is how the environmental and economic damage can be reduced.
