Shenzhen on Monday became the first city in China to launch a mandatory recycling program for furniture, home appliances, and other large, unwanted items: Residents need only schedule a pick-up time on WeChat. According to the local urban management bureau, companies and individuals who fail to properly recycle such items may be subject to reduced credit scores.

The southern city has long been at the forefront of recycling and waste disposal. It has offered an optional pick-up service for large waste since 2015, and it currently has 21 large-scale garbage-processing facilities operating at 70 percent capacity. In 2016, Shenzhen began construction on the world’s largest waste incinerator, amid vocal protests from local residents.
