1. Residents' awareness of classification is insufficient. Although the Shenzhen Municipal Government carries out publicity and education through various channels, many residents still have a weak sense of classification and do not know how to correctly classify garbage.
2. Insufficient classified delivery facilities. The sorting facilities in Shenzhen are not perfect, and some communities or streets are not equipped with sorting bins or sorting facilities, so it is difficult to encourage residents to sort garbage.
In addition, Shenzhen has not yet implemented compulsory classification, which is also one of the reasons that affect the accuracy of garbage classification.
