Recently the world is suffering from twin crises of fossil fuel depletion and environmental degradation. Increasing demand for fuel and uncertainty in their availability are two important triggering factors for searching an alternative energy source that can supplement or replace fossil fuels. Recently bio diesel has become more attractive for its environmental benefits and renewable resources, and it can be produced from insect fat content. Moreover, certain species of saprophagous insects have contributed to recycle the organic matter to fulfil their biological needs. Insects can be used to degrade organic waste materials to obtain economically viable biomass for animal feed. Fat content of insects varies widely between orders, species, stages of development, and dietary habits. Through their life cycle, insects are cultured with agricultural, restaurant wastes or urban by-products to accumulate a large amount of fat for conversion into energy through bio diesel production. This study mainly focuses on black soldier fly larvae as a bio conversion agent of the organic wastes such as crop residues, dairy manure, restaurant wastes etc. All these reasons make the mass rearing of insects a viable future for bio diesel production through bio conversion of waste materials, and it arises as an environmentally sustainable technology.
