This is pretty cool. A bus service in Scotland is giving discounts for used cooking oil.

How does it work? Well if you’re one of the 15,500 people who uses the Service One route from Stewarton to Darvel you’ll be given a container in which to save up your cooking oil. Once it’s full you take it to the recycling plant and in return receive vouchers giving you reduced bus-fares.
