Produce gas from cow dung

Biogas is a gas produced by anaerobic activity or fermentation of organic materials including; human and animal waste, household waste (household), biodegradable waste or biodegradable organic waste under anaerobic conditions. The main ingredients in biogas are methane and carbon dioxide.

Biogas can be used as fuel for vehicles or to generate electricity or to replace LPG gas.

The benefits of biogas are as follows:

• Biogas is good for environmental sustainability and makes the environment clean because waste utilization is usually only wasted and only pollute the environment but with certain techniques can be used as biogas that can be useful.

• Biogas can save the cost of household operations such as the use of biogas because fuel oil is more efficient than other fuels such as gas fuel.

• Biogas is useful for reducing levels of smoke and carbon dioxide in the air.

• Biogas can be used as fuel for power plants to replace diesel fuel as power plants.

• Biogas can reduce greenhouse gas emissions.

• Biogas can be used for organic fertilizer either solid organic fertilizer or liquid organic fertilizer for agriculture.

Here I will discuss how to manufacture biogas from cow dung to substitute LPG gas. The main building of biogas from cow dung for biogas installation is a digester whose function is to accommodate methane gas from the results obtained from the reshuffling of organic material caused by bacteria. The size of the digester is visible from the resulting cow dung and how much biogas is desired.

We recommend that the location where to build the digester must be adjacent to the cow shed so that cow dung will be easily channeled into the digester so that it can facilitate the process of making biogas.

Build a container of mud beside the digester, this mud container will be separated and can be processed to be made from solid and liquid organic fertilizers.

Step Making Biogas using cow dung as follows:

• Mixing cow dung sufficiently with the prescribed water is constantly stirred so that it will form like mud with a ratio of 1: 1 in the bath to be used for temporary storage.
• Drain the mud to the digester entrance. It is easier to insert sludge into the digester, the gas valve above the digester must be opened first and the air inside the digester will be pushed out. For the first filling it will require a lot of mud so that the volume inside the digester is fully charged.
• Apply 1 liter starter addition and fresh rumen contents from slaughterhouses for a total of 5 bags for a digester capacity of 3.5 to 5.0 m2. Once the digester is fully filled by the mud, the gas tap on the digester must be closed so that the fermentation process occurs.
• Dispose of the first gas produced from day 1 to day 8. On day 10 to day 14 will form methane gas (CH4) and CO2 gas and has begun to decline in fermentation. On day 14 it will form a gas that can light a fire on the gas stove.

Biogas is a gas that is colorless, odorless and very high and quickly lights a flame. The use of biogas has safer security when compared with LPG gas. For example, if a leak or leaking gas leak, there will be no explosion because the exit gas will evaporate quickly and if a fire is brought to the gas source there will be no fire that causes a fire. So biogas cow dung can be said to be safe fuel.
