To meet ASTM specifications for the conversion of oil to methyl ester, Kreido Biofuels, Inc. has successfully tested degummed soy bean oil, refined palm, jatropha, canola, castor, and soy oil as feedstocks for use in its STT 30G processors.

Kreido Biofuels' goal is to have a menu of "feedstock recipes" that meet ASTM specifications and work in its STT 30G processors.
