India processed about 11,38,000 tones of raw cashew nut seeds through 3650 cashew processing mills and it was is 26,274 tonnes in Tamil Nadu. The cutting and shelling operation performed in the mill generates huge quantity of the cashew nut shell that is about 67% of total weight of raw cashew nut seeds which were considered as solid waste in previous days but now it is processed to extract Cashew Nut Shell Liquid (CNSL) oil which has innumerable applications,such as friction linings, paints, laminating resins,,etc.At this junction, this study of extraction of Cashew Nut Shell Liquid oil (CNSL) from cashew processing waste(shells) in Cuddalore district of Tamilnadu was undertaken with the following objectives.(i)To Study the physical and financial Performance of CNSL units in the study area.(ii)To find out constraints in CNSL production and marketing and to offer policy implications. From the selected block of Panruti, 15 cashew processors who were engaged in cashewnut processing and CNSL extraction were selected at random. In order to assess the physical and financial performance breakeven and margin of safety analysis were carried out and to study the constraints in CNSL oil processing, Garrett’s ranking technique was employed . The results from the analysis showed that margin of safety at actual production,actual quantity of sales and actual value of sales were in comfortable position. But their average capacity utilisation(63.8 percent) were low due to many constraints associated with this industry. The identified constraints were ranked by Garrett scoring technique and from the results, it was found that seasonal availability was ranked first followed by heavy competition. This study suggested that all the stake holders in CNSL oil production and marketing should be properly trained for current events at national and global level which would in-turn enable the Panruti CNSL oil sector to compete in global environment.
