Indonesia’s second largest city, Surabaya, has just made it possible to exchange plastic waste for bus fares. To receive the bus fare, riders need only recycle plastics at one of the designated bus stops or recycling centres throughout the city. Alongside reducing plastics in landfills and the ocean, the government launched this innovative incentive scheme with a secondary objective of reducing private vehicle usage in the city – which accounts for 75% of the city’s traffic.
