Bio Diesel

BIO DIESEL

Bio-diesel contains no petroleum, but it can be blended at any level with petroleum diesel to create a Bio-diesel blend or can be used in its pure form. Just like petroleum diesel, Bio-diesel Operates in compression engine; which essentially require very little or no engine modifications because Bio-diesel has properties similar to petroleum diesel fuels. It can be stored just like the petroleum diesel fuel and hence does not require separate infrastructure.

The use of Bio-diesel in conventional diesel engines results in substantial reduction of un-brunt hydrocarbons, carbon monoxide and particular matters. Bio-diesel is considered clean fuel since it has almost no sulphur, no aromatics and has about 10% built-in oxygen, which helps it to burn fully. Its higher cetane number improves the ignition quality even when blended in the petroleum diesel. 

We encourage farmers to grow Pungan (Pongamia Pinnata) and Punnai (Calophyllum inophyllum) trees in the unused space of their farms & backyards. We give them saplings for no cost, if they believe in growing Pungan and Punnai trees for Bio-diesel. We don’t promote Jatropa as it occupies the regular food crop cultivation space. Our recent Pungan plantation was done in villages Lakshmananpatty and Andipatty, Dindigul district.

Pongamia pinnata (Pungan)

Pongamia pinnata is one of the few nitrogen fixing trees (NFTS) to produce seeds containing 30-40% oil. It is often planted as an ornamental and shade tree but now-a-days it is considered as alternative source for Bio- Diesel. This species is commonly called Pongam, Karanja, or a derivation of these names.

Oil

A thick yellow-orange to brown oil is extracted from seeds. Yields of 40% of volume are possible using a mechanical expeller. However, village crushers average a yield of 30%. The oil has a bitter taste and a disagreeable aroma, thus it is not considered edible. In India, the oil is used as a fuel for cooking and lamps. The oil is also used as a lubricant, water-paint binder, pesticide, and in soap making and tanning industries. The oil is known to have value in folk medicine for the treatment of rheumatism, as well as human and animal skin diseases. The oil of Pongam is used as a substitute for diesel.

 

Calophyllum Inophyllum (Punnai)

It grows near the sea coast throughout India. It prevents soil erosion. This native of the Pacific and of tropical Africa grows slowly along sandy shores and in lowland forests. It is commonly called as Undi, Nagchampa, Tamanu, Pannay Tree and Sweet Scented Calophyllum

The Success story of Punnai  Bio-diesel

Mr.Rajasekar, a Farmer from Kandiyankadu village, Nagapattinam District uses Punnai oil for his diesel needs. He runs his 5hp oil motor using 100% Punnai oil for the last 4 years. No blending of regular diesel. His oil motor’s engine hasn’t created any problem because of Punnai oil. He has also experimented in 10hp and 20hp generators. It went on well like regular diesel.

He further says, the cost of making one litre diesel is Rs.10 only. If a Farmer has got 10 Punnai trees in his farm, then his farm’s energy needs are met. This should be highly encouraged in a country like India where energy demand keeps on raising. Electricity on needed time is a dream for most of the farmers in our country. When you start using such alternatives, like Punnai oil, the dependency on carbon oriented electricity may slowly get reduced.
