An Alternative For the Daily Household Fuel Needs For Cooking Through Biogas With a Special Reference to Tripura
Today as the global energy demand increases, the price of the fossil fuels also increased. Due to this fact in
Tripura, people living rural areas are using firewood as their principal source of energy for cooking and heating purpose.
This source of energy has its share of ill-effects like, local deforestation, health issues etc. Scientist from all over the world
has been trying to find technologies to utilize various renewable energy sources present in nature e.g. solar energy. But in
comparison to other renewable source energy, biogas has proved itself in various parts of the world. It is basically a gaseous
mixture of Methane, Carbon di Oxide, and Nitrogen etc. where Methane is the main energy source in Biogas. It can be
produced in a digester through an anaerobic fomentation process called methanogenesis by anaerobic microbes namely
acidogens and methanogens. There are various types of feed stocks used for Biogas production, kitchen waste and
agricultural waste mixture co-digested with cow dung is most suited for Tripura. In the past Tripura government constructed
many Biogas plant and recently under IVBMMP (National Biogas and Manure management programme) it has
commissioned more than biogas plants. Deenbandhu model of Biogas plant was used for constructing the majority of these
plants. It has been estimated that in Tripura, if a family has 2 cows as their domestic cattle then they can produce enough
Biogas for their household. Even though Biogas technology is profitable but still only a fraction of the total population in
rural areas of Tripura are using it.
