Biodiesel is a transportation fuels like ethanol and diesel, Made from biomass materials. Bio fuels blend with the petroleum fuels like gasoline and diesel fuel. They are used on their own.

Uses of Biodiesel

Biodiesel is an environmental friendly fuel. Edible and non-edible vegetable oils produce the diesel. It can partly or fully replace diesel as a direct fuel. Every diesel engine powered vehicle can use this fuel on roads. (Millions of miles were logged on biodiesel in EU nations). Road construction, Mining, Farm machinery and marine engines uses this fuel safely. With new power generation capacity coming online, Biofuel makes an attractive choice to meet the regulations. Many stationary applications, Requiring exhaust emission control system, which will work well with biofuel not work with diesel fuel. With many states now mandating hybrid electric vehicles (including the fuel cell hybrid), biodiesel will make excellent reforming fuel.

Sectors using Biodiesel

Presently our customers are using Biodiesel for the following usages:

i)                 Textile industries uses as coning oil.

ii)               Chemical industries for usage as lubricant.

iii)              Jute industries as replacement of jute batching oil.

iv)             Marine industries replacing diesel by Biodiesel for fishing tra wler.

v)              Mining industries for use in the heavy duty earth moving equipment.

vi)             Stationery power generation industry for testing oil in boiler.

vii)           Pharma and Hotel Industries are replacing diesel with bio-diesel as a  boiler fuel.
