The rule came first, the technology after. Sorting into four streams was compulsory, with fines up to 200 yuan, before AI cameras arrived to grade bin-room purity and issue work orders.

Since 1 July 2019 Shanghai households must sort waste into four streams — recyclables, hazardous, wet (kitchen) and dry — with fines up to 200 yuan for residents and 50,000 yuan for organisations. A digital layer grew around the rule rather than with it: AI cameras that grade bin-room purity and auto-issue work orders, weighing devices on collection trucks, and a platform tracking containers and vehicles across all 16 districts. The Green Account points scheme rewards correct sorting, but a peer-reviewed study found the incentive largely stalled at community level.

Live 📅 since 2019 🤖 Uses AI

📊 Impact

Daily average of 7,927 t of recyclables sorted citywide in Jan-May 2025, 1.96 times the pre-regulation 2019 level (Shanghai municipal government). A peer-reviewed 2021 evaluation found about 83.62% of household food waste effectively separated at 99.50% purity.

🎓 Lesson

Shanghai had been asking households to sort since the 1990s and, on the peer-reviewed account, got little for thirty years; what changed in 2019 was not a technology but an obligation, backed by the one enforcement mechanism that needs no hardware at all — haulers who may refuse an unsorted load. The cameras, truck-mounted scales and citywide platform arrived years afterwards, to police a habit the rule had already created. The single component built to change behaviour rather than measure it, the Green Account points scheme, is the one that failed: a peer-reviewed study found the incentive nullified at community level, where targets devised for ease of measurement displaced what the policy was for.
