Learn about HomeBiogas
What is HomeBiogas?
HomeBiogas is a household system which converts food leftovers and animal manure into biogas that can be used for cooking, as well as natural, liquid fertilizer for the garden.
Who is HomeBiogas for?
HomeBiogas is compatible with both rural and urban lifestyles. The system is ideal for families who live in a warm climate area in a detached or a semi-detached home with a garden.
How much biogas is produced?
HomeBiogas produces 2-3 hours of cooking gas each day – the perfect amount for three meals.
Does HomeBiogas come with a warranty?
Yes. HomeBiogas comes with a 24 month limited parts and materials warranty.
How is HomeBiogas installed?
HomeBiogas is shipped to you in a small box. Unlike other biogas digesters, you do not need a technician to install the system. It is a do-it-yourself kit, that comes with all the necessary tools and detailed instructions. The system can be installed in 2 hours!
Do I need electricity to operate HomeBiogas?
No. The system is 100% off-grid.
How long after putting organic waste into HomeBiogas will it produce gas?
After installation, HomeBiogas may take between 2-4 weeks to produce gas.
What can I feed the system?
The system thrives on food leftovers such as rice, cheese, meat, cooking oil, vegetable peels, fruit and any other food waste. Avoid feeding large quantities of citrus fruit skin since it contains anti-bacterial oil which could reduce the effectiveness of the digestion.
What happens if I don’t feed the system for a while?
The system will digest all the waste inside the tank then stop producing gas.
Once you get back to feeding the system it will return to continuous biogas production.
How much waste can I feed HomeBiogas each day?
You can input up to 6 liters (6qt) of food waste or up to 18 liters (18qt) of animal manure into HomeBiogas each day.
Unlike composters, HomeBiogas can accept all food, including meat, fish, oil and fats.
How much gas can I produce with HomeBiogas?
Every liter of food waste produces about 200 liters of gas, the amount needed to cooking for one hour over a high flame. On average, HomeBiogas produces up to 2 hours of cooking gas each day – the perfect amount for a family!
For how long does a gas burner and barbecue grill run on a full HomeBiogas tank?
A full HomeBiogas tank can fuel a one-blade barbecue grill for 45 minutes, and can fuel a typical stove burner for about two hours.
How is the biogas stored?
The system can store up to 500 liters of Biogas at any given time indefinitely. The Biogas will remain in the Digester Tank until used.
Is the Biogas production continuous?
Yes! HomeBiogas converts waste to Biogas all the time, 24/7.
How safe is Homebiogas?
HomeBiogas is not only safe, it is safer than LPG and propane!
In order to remain in a liquefied state in storage, LPG must be kept under high-pressure conditions. This poses a greater risk of explosion when in the vicinity of an ignition source. HomeBiogas, on the other hand, purposefully stores the gas in a soft case, at a low pressure, which prevents explosion.
How safe is Biogas?
Biogas is made up of small molecules which are lighter than air. When released into the surrounding environment, the biogas loses its ability to ignite and will quickly diffuse upwards, leaving the premise immediately.
On the contrary, LPG and Propane sink to the ground, increasing the risk of toxic levels of exposure.
What safety regulations has HomeBiogas passed?
HomeBiogas has taken every precaution necessary to ensure that our system meets all safety standards.
-HomeBiogas was tested by and received the European Community CE stamp of approval for safety.
-HomeBiogas received two ISO certifications: certification 9000 for Quality Management and 14000 for Environmental Management.
-Lastly, HomeBiogas was tested by and approved for safety and health by the Israeli Ministry of Environmental Protection and the Ministry of Energy Infrastructure.
What type of maintenance is involved with HomeBiogas?
We recommend maintaining your HomeBiogas unit periodically by:
1. Replacing its gas filter once a year. The gas filter removes the hydrogen sulfide from the biogas.
2. Removing the sludge that accumulates at the bottom of the digestion tank. This should be removed once every three years. Once the sludge is removed, it can be applied directly to your garden as fertilizer or used to wet your compost heap.
3. Replacing the chlorine tablet if it has dissolved completely. The chlorine tablet disinfects the remaining bacteria in the liquid fertilizer.
Will it work in any weather?
HomeBiogas operates optimally in warm climates. Still, there are 2 actions that can be taken for colder regions to make the system operate well.
1) Add an electric aquarium heater to heat the digester tank.
2) Place the system in a greenhouse or in an indoor space that is warm and has proper ventilation.
Can I connect HomeBiogas to the existing appliances in my house?
Yes, you can connect HomeBiogas to an existing appliance. However, conventional gas stoves are not built for biogas, so you may need to convert it to work on biogas. Check our Stove Page to learn more.
How do I convert my stove into a biogas stove?
You have to take out the pressure reducing nozzle
(contact us for more details).
Does it smell?
There is a filter installed in the system to eliminate any unpleasant odors. We guarantee that the product piped into your kitchen is clean, safe, and smell free.
The system itself is designed with a weighted sink cover, making a closed system. This means that odors are contained inside the system and unlike with composting, no pests are attracted.
I have a composter, what is the added benefit of biogas?
HomeBiogas is the ultimate solution for organic kitchen leftovers. HomeBiogas can accept meat, fish, oil, bones and fats (which are not truly suitable for composters). Also, HomeBiogas produces biogas which can be used for cooking and liquid fertilizer every day, whereas composters may take several months to produce compost.
Can I fill HomeBiogas with grey water?
Yes. The system is grey water compatible.
