Following the waste classification regulations earlier this summer, Shanghai government is now adopting a smart approach in garbage sorting. A chip with GPS positioning has been embedded in each trash bin for residual garbage and household food waste to track down the waste sorting performance of each household in 13 villages of Hangtou Town in the Pudong New Area.
Smart chips have also been installed in garbage collection bins, transportation vehicles and treatment stations, forming a whole-process supervision and management system on the disposal, collection, transportation and treatment of trash via the Internet of Things technology.
When a garbage bin is put on a collection vehicle, information about the household which the trash bin belongs to and the weight of the waste is promptly shown on the vehicle’s screen via auto-induction.
Collectors then rate the sorting performance of the household into four categories — excellent, good, so-so and poor. The data is then transferred to a big data platform.
“The movement track of each garbage vehicle, its working status, working time, the sorting performance of each household, their scores and the amount of trash collected will be shown on the platform in real time, providing reference for our supervision and analysis,” said Wu Ping, director of the Hangtou Town Operation Management Office.
“The smart system helps us grasp each process of garbage sorting accurately and in a timely manner. If an abnormal situation or failure in waste sorting is detected, we will visit households and educate them and order transportation companies to rectify (the faults) immediately,” he said.
There is a director at each of the town’s eight garbage treatment stations, supervising the work of collectors, and a garbage sorting director for every 50 to 100 village households, responsible for the promotion and guidance of garbage sorting. The town has a population of nearly 200,000, about half of whom are from out of town.The volume of wet, or household food garbage, and recyclable garbage sorted in Hangtou has grown significantly.About 60 tons of wet garbage are sorted daily in Hangtou now, compared with 10 tons before July 1 when Shanghai’s new garbage sorting management regulations took effect.Some 98 tons of recyclable waste have been collected on a daily basis now, rising from 8 tons before July 1.
