Biomass energy ppt
This document provides an overview of biomass energy. It discusses that biomass is a renewable source of energy derived from organic material like wood, waste, and crops. Biomass can be converted into useful energy through combustion, gasification, anaerobic digestion, and liquid biofuels. In India, biomass potential is estimated at 95,000 MW and technologies like biogas from waste and co-generation in sugar mills are being utilized. While biomass energy has advantages like being indigenous and reducing emissions, it also has disadvantages like being dispersed and of low energy density.

- 18. Applications • Anaerobic digestionis used for effluent and sewage treatment. • Anaerobic digestion is a simple process that can greatly reduce the amount of organic matter which might otherwise be destined to be landfilled or burnt in an incinerator. • Almost any organic material can be processed with anaerobic digestion. This includes biodegradable waste materials such as waste paper, grass clippings, leftover food, sewage and animal waste. • Anaerobic digesters can also be fed with specially grown energy crops such as silage for dedicated biogas production.
