Used oil = carbon-neutral Scottish bus

A Scottish bus company encouraged enough riders to donate their used cooking oil for biofuel production, that they can now go carbon-neutral, reports Environmental News Network:

"For the past six months, Stagecoach has been running eight buses on biofuels made from used cooking oil. That project has the makings of a true bartering scheme; in exchange for used cooking oil, passengers get a reduction on travel fares. The scheme is organized at Ayrshire Council recycling plant and has been met with tremendous enthusiasm of the population. Over 21 tonnes of used cooking oil was handed, marking an 100 percent increase over a period of six months."
