Biodiesel From Animal Fat

- 

Fossil fuels support the majority of global energy needs, and the demand for these sources continues to rise, despite the efforts to shift towards renewable sources of energy. Due to the limited supply of fossil fuels there is a persistent search for alternative renewable energy sources, such as biofuels (biodiesel, bio-ethanol, etc.). Biofuels can be considered a renewable source of energy as long as they are based on sustainable biomass production. The advantages of biodiesel over conventional diesel fuel are its portability, ready availability, renewability, higher combustion efficiency, lower sulphur and aromatic content, higher cetane number, higher biodegradability, better emission profile, safer handling, besides being non-toxic. These characteristics make it more greener and eco-friendly than diesel.
