Production of Biodiesel from Organic Wastes by Bioconversion

Biodiesel comes in the category of renewable and biodegradable fuel. It has shown promising performances for substituting petroleum. Due to the outbreak of urbanization and population blast in recent years, there is enormous increase in the production of waste and also lack of its appropriate disposal. Municipal solid wastes, agricultural waste, industries and manufacturing processes generate large amounts of waste materials. The technologies associated with waste to energy conversion produce various types of fuel which are further utilized to meet the needs of energy. Production of synthetic fuels from organic wastes follows four important techniques like bioconversion, gasification, pyrolysis and hydrogenation. This chapter throws light on waste biomass, different categories of organic waste, utilization of organic waste for production of value-added products especially biofuels. Moreover, bioconversion of various types of organic waste into biodiesel guided by microorganisms, algae, insects, etc. are also discussed in this chapter.
