Biogas in Kenya
Biogas in Kenya
Use of biogas in Kenya is gaining popularity every day as a result of the many advantages it has over other sources of energy. Biogas in Kenya is used as a source of cheap energy. Homes, jails, schools and other similar settings make use of biogas.What is a biogas digester
A biogas digester simply means a tank that biologically digests organic material to produce biogas. However, most people think of it as a tank that digests organic material anaerobically without oxygen. The organic material produces methane gas which can be used for cooking, lighting, heating, etc. A biogas digester can be installed for simple household uses. It generates biogas from animal manure and other organic wastes. This enables families to cook with an environmentally friendly smoke-free fuel. The digesters also produce a slurry which happens to be very rich in Nitrogen. This makes it a great fertilizer to promote soil health as it contains manure and water. In addition, they save families a lot of money and time. Bio-gas has become a very important technology in Kenya. This is due to the fact that they give an on-site sanitation system rather than the common smelly sewer system. Bio-digesters never fill up hence you will never need exhauster services. The waste is usually used up in its continuous production. In Kenya, so many people have no connection to a sewer and for others; they are far from their homes. This is predominantly in the slums and other densely populated areas. Construction of a bio-digester for these people is a great advantage as it will come with added benefits. Free fuel in form of biogas is one of them and also a cleaner environment. Urban areas have a growing concern about crowding. This has created the need for a better and improved method of waste disposal and cleaner surroundings.What is the Cost of Biogas
Bio-gas is a renewable source of energy that cannot be depleted making it cheap. This is exceptionally easy for people with livestock. If one constructs their own bio-gas plant then it is basically free. When you use biogas, cooking fuel expenses can be reduced by as much as 80 per cent. It replaces firewood, charcoal and kerosene. Majority of Kenyans live below the poverty line. A basic home bio-gas unit costs between Ksh. 50,000 – Ksh. 800,000 which is many Kenyans still cannot afford. You can also construct your own bio-gas plant. Most constructors charge not more than Ksh 150,000 to put up a 12m3 biogas system. In Nairobi, people generate about 3,000 tons of waste every day most of which is organic. If all this waste was used to produce biogas then there would be fewer problems on fuel and lighting. Recently, development agencies of German and Japanese governments have been offering Kenyans one-year loans to construct biogas plants. All the farmers need to do is to have a source of organic matter. Most keep livestock which gives great waste for methane production. In the meantime, they can sell the cow’s milk to be able to pay back the loan. As the transition becomes more and more affordable, many poor Kenyans are increasingly switching to biogas. Traditional fuels like kerosene and gas cylinders are expensive and the prices keep hiking. Majority of people now prefer bio-gas due to its availability and cheap methods to produce it.Can Biogas be Used for Cooking
There are special stoves made specifically for cooking with biogas. They are called improved cookstoves. They have a valve to pre-mix bio-gas with adequate oxygen. It also has a well-designed burner to hold a cooking pot and combust the mixture. There is a tube that transports bio-gas from the digester to the cooking place. Bio-gas has no strong odour so it does not keep your home smelling. The flame from it is clean and clear as it has no impurities. This means that your dishes will not end up black with soot. The improved cookstoves ensure complete combustion and they are more efficient. In a way, they are similar to the cookers used for commercial gas fuels. These stoves can also use wood, charcoal and cow dung as well.
Biogas Digester Installation
Anybody who wants to construct a biogas digester has a number of considerations to make. These include;- Design – An efficient bio-digester must have an inlet, an outlet and a means to stir the materials as it grids them.
- Capacity– To calculate the size of the plant you take Cow dung/cow/day multiplied by the number of cows multiplied by two multiplied by 60, then divide everything by 1,000.
- Amount of gas expected – A cow can produce 15 kgs of dung per day. This can generate about 0.5m3 of gas. A farmer can multiply the number of adult cows by 0.5 to estimate the amount of gas in cubic meters per day. An efficient biogas burner uses about 0.5 m3 of gas per hour.
- Safety – ensure that open flames are never within six meters of a biogas plant. Before any repairs or inspections, technicians should ensure that all biogas is evacuated from a digester before they enter. This is because biogas can displace oxygen and cause suffocation.
- Management of the system– A digester must be fed regularly for a continuous supply of gas. The feeding frequency could be daily or weekly.

Hey,
I would like to know the cost of setting up a biogas plant for cooking in a learning institution with around 450 learners and roughly 20 members of staff.
Greetings! Hope this finds you you well thank you for contacting Biozone. Cost of biogas depends on the size of the biogas which is determined by the source of biomass(what your source of organic waste is it animals, human waste etc.) kindly help us with the above information for us to be in a position to share the cost.
