BIO GAS: Bio-gas present in the farm showcases one of the renewable energy sources available to man to reduce huge dependence on the non-renewable fossil fuel. This energy source also helps in reducing the energy bills due to the spiraling costs of the fossil fuel. The concept of bio-gas derives its idea from the process of fermenting the animal waste to produce methane gas. In the bio-gas plant the cow-dung from the mini-dairy in the farm is used to produce methane gas. The cow-dung from the dairy is mixed with urine and water in a tank and is moved to a larger circular tank covered with hollow metal tank. The hollow metal tank helps in fermentation process and also acts as a storage for the methane gas produced due to fermentation process. The fermentation process takes one to two days and results into production of safe methane gas. This gas is also much more safer as compared to LPG as it does not result into explosion. The methane gas produced and stored in the tank is then transported to the kitchen stove using pipeline. This gas is used along with specially designed stove to cook food for the household. This gas can also be used in place of LPG in generators to produce cheap electricity. This concept depicts the right use of naturally available cheap resources to produce energy thus helping in development of renewable energy resources at negligible costs and reduction in level of pollution caused due to use of fossil fuel. The bye product from the fermentation process is the slurry of the cow-dung which is used to produce compost fertilizer used in organic farming. ORGANIC FERTILIZER: The slurry from the bio-gas plant is mixed with foliage from the plants and is put into specially designed pits to produce fertilizer used in organic farming. The foliage and slurry is put in form of layers into the pits and is kept in the pits for a period of 3 to 5 months for decomposition. This decomposed manure is rich in all the required nutrients and is suitable for organic farming. This fertilizer can completely replace the chemical fertilizer used to increase the yield. This manure also increases the fertility of the soil unlike chemical fertilizer which result into erosion of soil fertility. FENNI DISTILLATION: The cashew apple produced in the farm is used to produce the world famous goan drink, Fenny. It is a very strong alcoholic drink produced only in Goa and surrounding areas. It has few special properties like it increases appetite and has no hangover effects associated with alcoholic drinks. The cashew apples are first crushed to form a homogeneous matter and is then squeezed to extract cashew apple juice. This apple juice is then kept in tanks for a period of 3 to 4 days to complete the process of fermentation. Proper fermentation is required to produce top quality liquor. This fermented juice is then distilled to produce first distillate called the Hurrac. This is the initial stage of producing Fenny. This distillate is less alcoholic and has strong smell. This distillate is then mixed with fermented juice in different quantities as per the requirement and is distilled again to produce the second distillate called Fenny. The amount of alcohol in the fenny depends on the mixture of the first distillate and the fermented juice. The Fenny can also be produced using different spices or vanilla to produce the flavored fenny. This also reduces the smell.
