Abstract:
The present invention describes a two stage process comprising a first stage of extraction of oils and/or fats with free fatty acids (FFA) from wastes originated in waste water treatment plants (WWTP), generally known as brown grease, grease traps, from WWTP of several food and dairy industries and from processing animal products, or other waste streams containing organic oils and/or fats and a second stage of conversion of the FFA obtained in the first stage into glycerol ester by a glycerolysis reaction without the presence of a catalyst.
