For promoting biodiesel govt.(state also)should give all tax exemption i.e. vat , excise on raw material.Then should clarify how to sell in market bcos psu rates r not at all feasible,open selling is not a leagal option.For getting fessibility in production import of waste veg. oil should be allow freely(now has to much ristriction ,& higher duties) which will make proposal attractive.This has to be done till we get good supply of oil indegenously. In all central as well as state govt. should make clear policy regarding bio Diesel i.e. how to sell ,all standards of BD ,tax exemption ,any subsidies etc. with out it there is no future for biodiesel in india.
