Diesel fuel (waste methyl ester, WME) production from waste vegetable oil due to the recycling and the environmental protection of rivers and sea has been carried out in Yaku town of Yakushima Island since October 1999. In this study, the collection of waste vegetable oil and the WME production were investigated. The part of waste vegetable oil sampled in Yakushima had high acid value (deterioration) compared with other area. The amount of gathered waste vegetable oil was 15-17 kL per year. This value was 35-45% of the amount in which the collection was possible. The fuel conversion ratio of WME from waste vegetable oil was 96%. The fuel properties of WME were the same as those presented by authors. The produced WME has been used as diesel fuel for the 20 vehicles of a Yaku town office.
