This paper describes the fundamental study about utilization of co-glycerol derived from biodiesel fuel (BDF) production especially exhausted from small BDF plant which has no facility to dispose them by themselves. The method to add value to this co-glycerol is refining and production of pyrolysis oil under low temperature around 450 °C, using small solar thermal collector (STC) with type of parabola trough as its heat source. As a result, the temperature inside STC was increased from atmospheric temperature to 450 °C in ca 30 minutes even though the amount of co-glycerol was changed to 6 ~ 20 g due to line symmetry derived from trough shape STC, then, the products were acquired in the form of oil, glyceride-rich layer, gasification gas and char almost the same way as those of using electric furnace as heat source. And it is shown that oil contains hydrocarbon such as n-pentane, n-hexane, n-heptane, etc., in addition to BDF, excess methanol of BDF production, mono-glycerides derived from tri-glyceride of resource of BDF used.
