5 Compilation rules of classification code
5.1 Structure of classification code
The classification code of general solid waste is composed of four segments, and the structure diagram for classification code is shown in Figure 1.
5.2 Source industry code
The source industry code is the 1st~3rd digits, which is determined by the waste source industry and coded according to GB/T 4754. When the 3rd digit is 0, the code represents the whole industry category. For the general solid waste with defined category code, if its source industry is not determined, the source industry code is 900.
5.3 Sequence code
The sequence code is the 4th~6th digits, which is determined by the sequence of source industry code in GB/T 4754. See Table 2 for details. For the general solid waste with defined category code, if its source industry is not listed in Table 2, the sequence code is 999.
