Biogas is a gas produced from the decomposition of organic matter by bacteria in the absence of oxygen (anaerobic digestion). Biogas is smokeless, flammable gas typically composed of 60% methane and creates a blue flame when burned, just like LPG or natural gas, and is 20% lighter than air. Home Biogas is a system that converts your organic waste into cooking gas for your home and liquid fertilizer for your garden.
The right climate (average day/night temperatures above 20°C/68°F) so Home Biogas can work optimally. A space to put the Home Biogas. The size of the system is 2.10m x 1.2m (6.8ft x 3.7ft) and it should be placed outdoors in an easy-to-access area within 20 meters / 65 feet of where you intend to cook. The last requirement is easy! You need a regular source of organic waste to feed Home Biogas. You can use your leftover food scraps from the kitchen, or if you have a small farm or homestead, you can use animal manure.
In addition to creating biogas cooking fuel, Home Biogas creates a bio-slurry fertilizer full of macro and micro nutrients which are in the right form for rapid absorption by plants. It can be replace putting manure or store-bought fertilizer on your plants. The ferilizer can increase growth and your plants' resilience to diseases. The liquid bio-slurry fertilizer is automatically ejected from Home Biogas through the fertilizer outlet as you add more organic waste and water into the system each day. The quantity of fertilizer produced by the system is equal to the quantity of feeding. If you feed it the maximum quantity recommended which is 12 liters per day, you should receive 12 liters per day of fertilizer. Consistent quality in the fertilizer comes from constantly feeding the system a diverse mix of organic waste. If you have fed humanure to the system, you should use an ecological design process to mange the waste and not put it directly on edible plants. We call the fertilizer organic because it comes from organic matter. "Organic waste" and "organic products" are two different things. "Organic products" have been third-party certified because they meet certain standards. "Organic waste" simply refers to organic matter that has come from a recently living organism (including plants). In a way, if your kitchen waste is only organic, it can be called "organic waste".
The bio-toilet is an off-grid solution that can be integrated with the Home Biogas system. The Bio-Toilet connects directly to the biodigester, eliminating any hassle or mess. WIth 1.2 literse per flush, you will save water, get even more fertilizer, and help eliminate environmental pollution from human waste by using an ecological method for breaking it down. The bio-toilet kit comes with all the pipes that you need to connect the toilet to the Home Biogas system, as well as detailed instructions for assembly and attachment. You can purchase one along with the purchase of your system or you can purchase one separately and attach it to your working system later. The dimensions of the bio-toilet are 52W/52L/43H and it weighs 12.5 kg. To see more information about how the system works please see the bio-toilet page. The cost of the system and toilet combined is 890.00 US dollars.

Getting Started

You don't need an expert or technician to install Home Biogas, you can do it by yourself! Installation is easy with a step-by-step assembly manual, and takes only about an hour with two people.
The best way to activate Home Biogas with bacteria is to feed the system with 100 liters (25 gallons) of fresh or semi-fresh animal manure (cow or horse is best). Put it in the system and wait 3-4 weeks until a healthy bacteria colony grows. Once you are able to ignite a flame at your stove, the system is ready to use. After that, you can start using the biogas for cooking and feeding the system with food scraps if desired. If you don’t have access to animal manure you can activate Home Biogas with a bacteria starter kit. What to keep in mind:
  • Summer is the best time to activate your Home Biogas system. For the first several weeks, the weather needs to be at an average day/night temperature of 25 °C (77 °F) or above.
  • For the first two weeks the maximum input of organic waste should not exceed 3 liters per day, in order to give the system time to maximize the digestion process.
  • The system will usually begin to produce gas within two to three weeks after activation, depending on the surrounding temperature and the quality of the manure.
There are a few things to consider when choosing where to place your Home Biogas system.
  • The system should be placed within 20 meters/65 feet of the location of stove.
  • The system should be installed as close as possible to the kitchen, adjacent to the wall of the building if possible.
  • It is important to place the system on a firm, leveled surface clear of any obstructions such as stones, tree roots and vegetation. The system weighs 1200 kg when full of water, and it will sink into soft ground.
  • It is recommended that the unit be installed in an area which is exposed to direct sunlight. Gas output and system functionality increase with heat.
  • 0.5m space should be left on each side of the system in order to access it easily, especially the sink where you input the food.  (the total space needed is 300 X 200 CM)
  • It is recommended to have a water source accessible nearby (ideally a garden hose with a spray nozzle).
  • The gas pipe from the system to the stove should be protected to prevent accidental damage and should not be bent or folded. It can be run through a larger metal pipe.
  • Ensure that the pipe always runs at the same height or higher than the system base to allow effective water drainage from the gas pipes.
After you assemble, it's time to activate your system! Activation is the way you get bacteria into the water container so that it can start producing biogas. Activation is only done once in order to get the system activated with hungry bacteria.

Using Laobiogas

You can feed Home Biogas with both animal manure and food waste. There is no minimum feeding amount, but there is a maximum feeding amount. Maximun feeding amount per day: Food waste: 6 liters / 1.5 gallons OR Animal manure: 20 liters / 5 gallons (well mixed with equal amount of water) Every kilogram of food waste produces approximately 200 liters of gas which is equivalent to 1 hour of cooking on a high flame. You can feed Home Biogas with leftover food, including grains, dairy, meat, cooking oil, peels, fruits and vegetables, and other wet food waste. You should not feed Home Biogas , wood shavings, straw, dirt, sand, tree branches, paper, metal, plastic, glass, grass, or any non-organic liquid. You should also avoid a large quantity of citrus peels or hard pits (e.g. from avocados). Citrus peels change the pH level and pits are difficult to digest. Animal manure should be without sand or litter, and should be moistened before being added to create slurry. If you have the newest Home Biogas accessory, the Bio-Toilet, you can treat your human waste as well. Learn more about the Bio-Toilet here.
Every Home Biogas 2.0 purchase comes with a specially adapted biogas stovetop and a yellow pipe, which carries the gas to the stovetop.  Connecting the biogas stovetop to the Home Biogas system is easy and does not require a technician! Almost any LPG/propane gas stove can be converted to work on biogas, however, we recommend using the stovetop that comes with your Home Biogas purchase. The system can hold a maximum of 4.4Kw/h; and can provide up to 4 Kw of gas. A typical burner usually needs between 1-2Kw. Please verify the stove’s specification, and be aware that if the burners collectively consume over 4.4kw/h then two flames will not simultaneously light. It is not possible to switch between using biogas and LPG. The gas characteristics are different between biogas and other gases, and therefore it is not considered safe. To understand what all your options for a stove is, please refer to ‘Stove Options’:
You can feed up to 6 liters / 1.5 gallons of food waste and 20 liters / 5 gallons of animal manure (always well mixed with an equal amount of water). You may combine kitchen waste with animal manure in the same system. Every kilogram of food waste produces approximately 200 liters of gas which is equivalent to 1 hour of cooking on a high flame. Stove cooking time may be up to 2 hours per day. Daily gas / energy output: 700 Liters of gas = ​ 3850 calories = 4.4 kwh = 15.4 mega-joules 0.33 liter/ 1.83 cal/ minute. The system does need a minimum amount to keep functioning, but it also depends on what you are feeding it. Some materials are already partially digested/decomposed and some of the work has been done, so it takes a different amount of time and subsequently produces a different amount of gas.
Because Home Biogas is filled up with water, bacteria and organic waste, it should not be relocated unnecessarily. However, the system can be relocated if needed by siphoning some of the fluid from the system (we provide instructions on how to siphon correctly).
It is possible to use the biogas for appliances other than a stove because it can be connected to any system which supports the use of gas. However, we do not recommend this type of connectivity. You should consider that the system can produce and accumulate up to 700 liters of gas per day, which typically is not sufficient to support many appliances (i.e. water boiler, refrigerators, generators, etc.). The system can hold a maximum of 4.4Kw/h; and can provide up to 4KW. If you decide to connect the HomeBiogas to a gas appliance, please refer to the appliance technical specifications for compatibility. The best use of the gas is to use it for cooking – consider the fact that you through using the gas for cooking you can complete a natural ecological cycle by putting your food waste into the system, cooking food on the gas you create, and fertilizing the food the grow in the garden with the liquid fertilizer.

Safety

It most certainly is! In fact, the biogas produced in Home Biogas is actually much safer than your current LPG (liquified petroleum gas) or propane gas tank for several reasons:
  1. Unlike LPG cylinders or propane tanks, the biogas in the Home Biogas system is not compressed. Our safety engineers intentionally created a soft case to hold the biogas so that it is stored at a low pressure.
  2. Since the gas is not compressed, the appliance stores a relatively small quantity compared to gas stored in cylinders. It is too little to pose a serious threat if ignited and is a minuscule amount compared to any other gas connection.
  3. Methane, which makes up 60% of biogas, is lighter than air and will diffuse immediately into the atmosphere if released from the appliance for any reason. This occurs naturally in waste disposal facilities like landfills all the time. What is unique about Home Biogas is that we are harnessing the energy potential of the potent greenhouse gas (methane) before it is released into the atmosphere.
  4. Methane needs a concentration of 50% to be flammable. The moment it hits the air it becomes less concentrated, rendering it completely nonflammable.
If you will be away from home for vacation and aren't sure about leaving your Home Biogas unattended, don't worry! The biogas will stay in the gas bag, waiting for you to use it and the bacteria will stay in the digester, waiting to be fed again. If your gas bag is filled to capacity and the bacteria inside the digester continue to produce biogas, any excess biogas that does not fit inside the gas holder will be automatically released from the system through a specially designed pressure-release mechanism. The pressure-release mechanism ensures that there will never be excessive pressure on the gas bag, so you can be completely at peace on your vacation!
Home Biogas should always be placed outside and should never be placed inside your house because the system needs both direct sunlight for heating and also because it automatically releases excess gas. If you put your Home Biogas in a greenhouse for the winter months, please make sure it is properly ventilated, as excess gas will be released automatically.
We have taken following steps to validate the quality and the safety of our system:
  • The unit was audited for safety by a qualified safety engineer who is a biogas expert; this expert certified our system to be extremely safe. A full safety report is available upon request.
  • European CE certificate for safety.
  • Home Biogas LTD is ISO 9001 (for quality) and 14001 (for environmental compliance) certified.
  • We provide an international insurance coverage through a product liability insurance that covers injuries or damages.
  • Our products were approved for installation and use by EU and Israeli governmental institutions that funded deployment projects in the Palestinian Authority and Israel.
  • Our products have been sold to thousands of users in over 90 countries. In order to promote and advance standards for domestic biogas systems, we joined the International Standards Organization (ISO)TC255 Technical Consortium that is defining the standards for all types of biogas systems.
Currently there is no international or national standard or regulation for domestic biogas systems. The reason is that this is a relatively new product and it takes time to write and certify standards.  As the standard bearer for the new, evolving standards, even prior to their publication, we are designing our products to meet those standards once they are in place.
The system can store up to 700 liters of Biogas at any given time indefinitely. The Biogas will remain in the Digester Tank until used. You can buy an additional gas tank (or two!) if you would like to store more than 700 liters of gas. We recommend that you use the gas on a daily basis. If you decide to compress it, consider that you will need a compressor which requires electricity and you may deal with pressure challenges. We recommend consulting with a professional gas technician to see if it is possible.

Maintenance

Home Biogas estimated lifespan is 15 years. All the materials were tested under extreme conditions, QA tested and come with manufacturer's warranty. Since the system is built in a modular way, it would be easy to replace any part of the system at any given the if needed. The initial warranty that comes with purchasing the system is 24 months parts and materials. Home Biogas is made of high quality UV protected Polyethylene and Polypropylene. These materials can be recycled.
