Biofuel & Biodiesel

Bio fuel can be broadly defined as solid,liquid, or gas fuel derived from recently dead biological material. This distinguishes it from fossil fuels, which are derived from long dead biological material. Bio fuel can be theoretically produced from any carbon source, though the most common by far is photosynthesis plants. various plants and plant derived materials are used for bio fuels manufacture. Bio fuels are used globally, most commonly to power vehicles and cooking stoves. Bio fuel industries are expanding in Europe, Asia and the America.

Bio fuels offer the possibility of producing energy without a net increase of carbon into the atmosphere, because the plants used in to produce the fuel have removed CO2 from the atmosphere, unlike fossil fuels which return carbon which was stored beneath the surface for millions of years into the air. Therefore, bio fuels is in theory more nearly carbon neutral and less likely to increase atmosphere concentrations of greenhouse gases.

There are two common strategies of producing Bio fuels. One is to grow crops high in sugar or starch and then use yeast fermentation to produce ethyl alcohol. The second is to grow plants that contain high amounts of vegetable oils such as oil palm, soybean , algae. When these oils are heated their viscosity is reduced, and they can be burned directly in a diesel engine, or they can be chemically processed to produce fuels such as bio fuel.
