印尼市民可用塑料瓶兑换公交车票
Dozens of people clutching bags full of plastic bottles and disposable cups queue at a busy bus terminal in the Indonesian city of Surabaya -- where passengers can swap trash for travel tickets.
在印度尼西亚泗水市一个繁忙的公交终点站，数十名乘客手持装满塑料瓶和一次性杯子的袋子在排队，他们可以用垃圾换取车票。
The nation is the world's second-biggest marine polluter and has pledged to reduce plastic waste in its waters some 70 percent by 2025 by boosting recycling, raising public awareness, and curbing usage.
The Surabaya scheme has been a hit in the city of 2.9 million, with nearly 16,000 passengers trading trash for free travel each week, according to authorities.
"This is a very smart solution. It's free and instead of throwing away bottles people now collect them and bring them here," explains 48-year-old resident Fransiska Nugrahepi.
An hour-long bus ride with unlimited stops costs three large bottles, five medium bottles or 10 plastic cups. But they must be cleaned and cannot be squashed.
Franki Yuanus, a Surabaya transport official, says the programme aims not only to cut waste but also to tackle traffic congestion by encouraging people to switch to public transit.
