One effective method is to follow polluter-pays principle (PPP).
Some cities could adopt a household MSW collection charge, which
follows the same line as the charge of water and natural gas supplied
in China. People should pay a fee according to the volume,
the weight of MSW or even the usage of plastic bags and containers.
The PPP is a good way to clarify polluters’ responsibilities, thus
giving full play to the price leverage of MSW collection and promoting
waste minimization.
