The extraction of Biodiesel. Oil extraction, cultivation and seed cake for various types of edible oil seeds

Abstract or Introduction

The fundamental advantage of biodiesel is that it can be depicted as "carbon impartial". This implies the fuel creates no net yield of carbon as carbon dioxide (CO2). This impact happens in light of the fact that when the oil crop develops it assimilates the same measure of CO2 as is discharged when the fuel is combusted.

India is the largest producer of oilseeds in the world and the oilseed sector occupies an important position in the country’s economy. The country accounts for 12-15 per cent of global oilseeds area, 6-7 per cent of vegetable oils production, and 9-10 per cent of the total edible oils consumption. The area and production under the nine oilseeds was 26.11 million ha and 24.88 Mt, respectively in 2009-10, whereas the total edible oil production in the country stood at 6.17 Mt in 2009-10. As per the fourth advance estimates for 2010-11, the production of total nine oilseed crops is 31.10 Mt, which is a quantum jump over previous year’s production. Oilseeds area and output are concentrated in the central and southern parts of India, mainly in the states of Madhya Pradesh, Gujarat, Rajasthan, Andhra Pradesh and Karnataka. In India, edible oil consumption has been growing steadily over the years. From around 5 Mt in 1990-91, the aggregate consumption of edible oils has gone up to 14 Mt in 2009-10. Groundnut, rapeseed-mustard, soybean and palm oil account for around 60 per cent of the edible oils consumed in the country.

In rural and urban India consumption of all edible oils per month increased from 0.37 kg and 0.56 kg respectively, in 1993-94 to 0.64 kg and 0.82 kg in 2009-10. This translates into an increase of 72 per cent and 46 per cent, respectively, among rural and urban households. The edible oils requirement of the country has been projected at 16.34 Mt in 2016-17 and 20.36 Mt in 2020-21, i.e. at the end of 12th Plan and 13th Plan, respectively.
