In September 2009, the city of Higashiomi launched a used cooking oil collection service for residents using its municipal "Chokotto" transit buses (chokotto bus means "quick bus ride" in Japanese).

　　在日本，地沟油被制作成蜡烛。2009年12月，日本东近江市针对乘坐城市公交快线的本市居民，发起收集废弃食用油的行动。

　　The collected cooking oil is refined and recycled for use as biodiesel fuel (BDF) in the very same buses, which run on 12 routes through the city.

　　收集上来的食用油通过提炼，最终变成生物柴油，为运营在该市12条线路上的快速公车提供燃料。
