NOVELTY - System (100) comprises: a source of an oilseed product; a source of supercritical carbon dioxide; a source of alcohol; an extractor (184) in communication with the source of an oil-seed product and the source of supercritical carbon dioxide, where the extractor has an outlet; a reactor (140) in communication with the outlet of the extractor and the source of alcohol, where the reactor has an outlet (146); and a power source (150) that operates on a biofuel energy source to produce heat.    USE - The system is useful for producing a biofuel product (claimed).    ADVANTAGE - The system provides the glycerol free biofuel product at high yields and eliminates the need for separation of alcohol from the biofuel product, hence economical.    DETAILED DESCRIPTION - System (100) comprises: a source of an oilseed product; a source of supercritical carbon dioxide; a source of alcohol; an extractor (184) in communication with the source of an oil-seed product and the source of supercritical carbon dioxide, where the extractor is constructed to afford suitable mixing of the oilseed product and the supercritical carbon dioxide under conditions to extract seed oil from the oilseed product, and the extractor has an outlet; a reactor (140) in communication with the outlet of the extractor and the source of alcohol, where the reactor is constructed to afford suitable mixing of the seed oil with the alcohol under conditions to transesterify the seed oil, thus producing a biofuel product, and the reactor has an outlet (146); and a power source (150) that operates on a biofuel energy source to produce heat, where the power source is in communication with the outlet of the reactor to utilize a first portion of the biofuel product as its biofuel energy source. The system further includes at least one of: a heat transfer mechanism that transfers heat from the power source to the extractor and/or the reactor; or a collection reservoir that receives a second portion of the biofuel product. INDEPENDENT CLAIMS are also included for:    (1) making a biofuel product, comprising providing a vegetable oil and reacting the vegetable oil with a supercritical alcohol under conditions to transesterify the vegetable oil and form a biofuel product substantially free of glycerol, and which does not require further separation of alcohol from it; and    (2) a biofuel product made by the method.
