Vanguard Synfuels produces the highest quality biodiesel because it not only has highly qualified chemists and managers, but the most up-to-date tools and equipment needed to do the job with expertise.


A complete on-site GC laboratory has all the instruments necessary to certify that all biodiesel produced meets ASTM D6751 and EN 14214 specifications. The lab is run by a professional chemist with 30 years experience, three directly in biodiesel. Equipment is state-of-the-art including use of a spectrometer to test at certain points during the production cycle. This ensures completed product reaches finishing tanks on time and in spec., and prior to the final Certificate of Analysis testing is performed.
