We've published a detailed article on how to sort household waste in Shanghai according to a list of categories including wet, dry, recyclable, and hazardous waste. The government has also released an official guide recently. With pictures! You might want to save it on your phone.
Impressive design skills, as always.
Still, there are things that might confuse people: food that contains hard shells might go to dry or wet waste bins, depends on what they are. Coconut and durian shells, as well as corn leaves and zongzi leaves, should go in to dry waste bins, because they contain coarse fiber and are difficult to compost. The same for shellfish and big bones; meanwhile, lobster shells (including xiaolongxia) go to the wet bin.
To understand the rules more easily, netizens came up with a Peppa Pig guide on how to sort waste, mostly relying on what happens to her when she eats certain garbage. Not entirely accurate, but ... serviceable.
(Pretty sure Peppa Pig has a high chance of dying if she eats cosmetic products, which actually go in the dry bin instead of the hazardous bin. Except for nail polish and nail polish remover. These are hazardous. Peppa is grateful for your attention.)
It's mafan but it's great. We have to pay more attention to what we consume, and strict garbage sorting regulations is beneficial to our health and the earth. You don't want the earth to go bad, do you? Maybe people might even start boycotting environmentally-unfriendly products because of how much of a headache they'll be to recycle. Jiayou, Shanghai!
