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.

Research Objective and Scope
This report investigates the complex landscape of the Indian oilseed economy, focusing on current production trends, edible oil consumption, and potential policy interventions to improve self-reliance. It examines the technical processes of biodiesel production, including various oil extraction techniques and the nutritional value of resulting seedcakes, to provide a comprehensive overview of how to enhance the value-chain of edible oilseeds.
- Analysis of temporal and regional trends in oilseed production and productivity.
- Evaluation of the current demand-supply gap in the Indian edible oil sector.
- Technical comparison of oil extraction methods including mechanical, solvent, microwave, and ultrasound-assisted approaches.
- Assessment of cultivation requirements for major oilseeds like coconut, sunflower, soybean, rice, cotton, rapeseed, and camelina.
- Investigation into the energy potential and nutritional composition of seedcakes as by-products.
Excerpt from the Publication
6.4. Microwave Assisted Extraction Method:
Around 2.5 g tests of powdered flax with moisture contents of 4%, 8% and 12%, readied as previously described, were blended with ethanol in a proportion of 1:3 g/mL(solid to dissolvable) . Before microwave treatment, the location of the greatest warm radiation of the oven was identified with a warm paper, and all the samples were set at that position for most extreme consistency in experimental results. The blend was put in a 100-mLflask with an elastic plug, with a moment gap to release any overabundance weight, and thermally treated in a microwave oven (1025C, Merry Chef Ltd, UK) with a yield small scale wave force and recurrence of 1025 W and 2450 MHz, respectively, and worked at the half power level. The thermal treatment was planned so as not to hoist the sample temperature for a really long time. The warming time was10 s and promptly took after by a cooling time of 5 min with mixing after every 10 s of microwave warming; a temperature extending from 55 to 60C was watched after each 10 s of microwave treatment as measured with an infrared thermometer (RS-1327 K, RS Components Ltd, UK). After every treatment, the level of dissolvable in the flask was kept up by including ethanol; around, a total of 10 mL of ethanol was expended per test. The total time of microwave treatment was 3 min for each sample (i.e. 18 10 s). After the microwave heat treatment, the samples were permitted to settle for 12 h. The supernatant layer containing the oil dissolvable blend was pipetted from the strong de-oiled cake and dissipated in the water shower at80C to recuperate the oil, which was weighed [4].
