Toxic feedstock to power buses in China

The Shanghai Food and Drug Safety Authorities has been working with Tongji University to provide city buses with biodiesel in 2014.

The partnership conducted a toxic oil recycling programme and will now use swill oil as the basis of fuel for 1,000 buses, despite officials admitting the two processors the city boasts are ‘limited’.

Swill oil made headlines for another reason a few years ago when it was discovered many restaurants were using the toxic oil in their cooking.
