Shanghai to roll out 1,000 biodiesel buses after successful trial

In China, the year-long trial of 104 buses running on a biodiesel blend in Shanghai has been deemed a success and will be rolled out further to 1,000 buses this year. The 104 buses ran a total of 2.3 million kilometers. Using biodiesel in buses provides an alternative market for used cooking oil rather than the oil going back into the human food market.
