Carbon footprint of strait vegetable oil and bio diesel fuel produced from used cooking oil

Abstract

Carbon Footprint of two different type fuel production systems, made of/from used cooking oil, i.e., Strait Vegetable Oil (SVO) and Bio Diesel Fuel (BDF), resulted a substantial GHG emission credit on SVO, -3.45 kg CO 2 e, compared with that of BDF, -2.95 kg CO 2 e, predominantly due to the emissions derived from methanol and electricity used in the BDF production. The cost analyses also favoured the SVO system at 82 JPY credit if steam use was excluded, approximately 27 JPY advantageous than the BDF system, due to the extra costs of methanol, electricity and absorbent used in the BDF production.
