On the one hand, it is necessary to improve the relevant mechanisms, clarify the responsibilities of managers, and formulate effective measures to make the garbage sorting work more secure. For example, Germany has established a garbage traceability system and implemented standard garbage bags with bar codes. Once anyone's garbage is not classified, they will be asked to classify it again. On the other hand, through some incentives, people can experience the practical benefits brought by garbage sorting. For example, Swedish government departments have automatic recycling machines for cans and glass bottles in many supermarkets. After the customer finishes drinking, he puts the cans and glass bottles in, and the machine will spit out the receipt, with which the customer can receive a small sum of money. In short, a multi-pronged approach, do a good job in every link, will really do a good job in garbage classification.
