City legislators are calling for regulations on the management of domestic waste to set a unified standard for garbage sorting and a system of rewards and penalties for residents.

A proposal filed by 13 legislators also said kitchen waste should be used to make organic fertilizer and waste packaging should be recycled.

Li Ming, a deputy to the Shanghai People’s Congress’s Yangpu District delegation and also initiator of the proposal, told Shanghai Daily the waste problem should be solved step by step and the first step should be separating wet waste from dry and recycling both.
