Learn about HomeBiogas
What is HomeBiogas?
HomeBiogas is an appliance you put in your backyard, which converts food leftovers and animal manure into biogas that can be used for cooking, as well as natural, liquid fertilizer for your garden.
Who is HomeBiogas for?
HomeBiogas is compatible with both rural and peri-urban lifestyles. The appliance 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 2.0 produces up to 3 hours of cooking gas each day – the perfect amount for three meals.
Does HomeBiogas come with a warranty?
Yes. HomeBiogas 2.0 comes with a 24 month limited parts and materials warranty.
How is HomeBiogas 2.0 installed?
HomeBiogas 2.0 is shipped to you in a box. Unlike other biogas digesters, you do not need a technician to install the appliance. It is a do-it-yourself kit, that comes with all the necessary tools and detailed instruction manual. The appliance can be installed in 1 hour!
Do I need electricity to operate HomeBiogas?
No. The appliance is 100% off-grid.
How long after putting organic waste into HomeBiogas 2.0 will it produce gas?
After installation, HomeBiogas 2.0 may take between 2-4 weeks to produce gas. After that, it should produce biogas 24/7, as long as you feed it with organic waste.
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 digester will breakdown all the organic waste inside the tank, then stop producing gas. Once you get back to feeding the appliance, it will return to continuous biogas production.
How much waste can I feed HomeBiogas 2.0 each day?
You can input up to 12 liters (12qt) of food waste or up to 40 liters (40qt) of animal manure into HomeBiogas 2.0 each day. Unlike composters, HomeBiogas can accept all food, including meat, fish, oil and fats.
How much gas can I produce with HomeBiogas 2.0?
Every liter of food waste put into the appliance produces about 200 liters of gas, the amount needed to cooking for one hour over a high flame. On average, HomeBiogas produces up to 3 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 2.0 tank?
A full HomeBiogas 2.0 tank can fuel a one-blade barbecue grill for about 1.5 hours, and can fuel a typical stove burner for about 3 hours.
How is the biogas stored?
The appliance can store up to 700 liters of biogas at any given time, indefinitely. The biogas will remain in the gas bag until used.
Is the biogas production continuous?
Yes! HomeBiogas 2.0 converts waste to biogas all the time, 24/7, so long as you feed it with organic waste.
How safe is HomeBiogas 2.0?
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 2.0, 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 appliances 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 2.0?
We recommend maintaining your HomeBiogas 2.0 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 digester. This should be removed once every 3-5 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 2.0 is made to function in an average of 20 degree C temperature. If you live in a much colder climate, you will need to take steps to warm the appliance to an average of 20 degrees, so that it will work properly.
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 2.0 to the existing appliances in my house?
Yes, you can connect HomeBiogas 2.0 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 HomeBiogas 2.0?
HomeBiogas 2.0 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 2.0 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 2.0 with grey water?
Yes. The system is grey water compatible.
