Gasification: Sources of Energy

India still continues to face challenges with regard to poor waste management systems even after development of various new technologies. Improper segregation is the root cause for this problem.  Improper segregation reduces the calorific value of waste. This leads to failure of various technologies. On the other hand, India continues to face energy crisis. Waste can be used as source of energy. Comparison of various technologies like incineration, biomethanation, RDF, composting indicates that Gasification is one of the most suitable technologies, especially at small scale level. Gasification can replace L.P.G. but it needs proper filtration. After laboratory scale experimentation it was found that 100% producer gas based gasifier produces up to 12m3 gas per hour and uses 4kg biomass per hours producing 1kg equivalent L.P.G. It generated 1100Kcal/hour thermal heat and 4KWe electrical output. It was found that Generation of flammable gas took place in just 12 minutes. Finally this paper highlights about application of gasification system in Government Schools and cost benefit assessment in terms of saving from LPG through Mid Day Meal programme.
