地溝油竟可以變廢為寶？

        在日本，地溝油被收集起來，經提煉變成生物柴油。一些垃圾車使用的正是這種環(huán)保燃料

　　To recover used oil most efficiently, the focus of the bus-collection service is to promote citizen involvement.

　　公車收集廢油這個點子主要是為了鼓勵全民參與的熱情，以達到更好地回收地溝油的目的。

　　For residents, the system works like this: first, they peel off the labels from the empty clear plastic cooking oil bottle and rinse it; next, they fill it with their used cooking oil. Finally, they pass the full bottle to the bus driver when they get on the bus, and in return they receive a Chokotto Bus "Eco-Tomo" (which means "eco-friendly") voucher to use as a fare ticket worth 100 yen (about U.S.$1.1) on their next bus trip.

　　市民首先要做的就是撕掉空塑料油瓶的標簽并將它清洗干凈；接著將廢棄食用油倒入瓶中。最后他們只要在乘公交時將這些瓶子交給巴士司機，同時為獎勵其為環(huán)保做出的貢獻，市民也會得到價值100日元（約合1.1美元）的車票代金券，下次乘車時就可使用。

　　There are also Candles made from used cooking oil and recycled glass.

　　此外，廢棄食用油及回收的廢玻璃還可以用來制作蠟燭。
