6.4 Mechanical pretreatment.
a) Screening and crushing. USE the combination of screening and crushing machinery to separate the different components in the primary waste and create good physical conditions for the recycling, subsequent
pretreatment and final disposal of domestic waste;
b) Prefabrication. The separated part of the material is processed to form an intermediate material that is favorable for subsequent processing;
c) Magnetic separation. Separate ferrous metal.
7 Sorting and recycling
7.1 Basic requirements
7.1.1 It is advisable to use mechanical sorting as the main method,
supplemented by manual sorting.
7.1.2 In accordance with the requirements of subsequent processing, SELECT the economical and practical sorting process.
7.1.3 RECOVER some of the available substances in domestic waste.
7.1.4 Residual wastes after sorting and recycling of domestic waste shall be further treated or disposed of, to meet the requirements of harmlessness. 7.2 Waste plastic recycling
7.2.1 The recycled plastic shall be subdivided in accordance with its main characteristics.
7.2.2 Sorting of waste plastics should adopt wind separation and flotation techniques.
7.2.3 The waste of plastic compounded with other materials shall be broken up to separate other composite attachments. It should use the dry crushing technique.
7.2.4 Waste plastics shall be cleaned to remove surface debris and dried, then granulated.
7.2.5 The cleaning of waste plastics shall use mechanical cleaning technology AND be equipped with wastewater treatment facilities.
7.2.6 The waste plastics obtained by sorting can either be used as needed, or be further processed to produce building materials such as paints, adhesives, plywood, and plastic bricks. The quality of its materials shall comply with the 7.7 Waste leather, waste rubber recovery
7.7.1 Waste leather separated mechanically or manually should be collected and packaged separately.
7.7.2 Waste rubber separated mechanically or manually shall be collected and packaged separately.
7.7.3 It shall remove the attached dirt from the waste leather and waste rubber. 7.7.4 It should strip off the metal materials from the waste leather and waste rubber manually or mechanically.
8 Biological treatment

8.2.2 The domestic waste aerobic composting techniques shall meet the
requirements of CJJ/T 52 and CJJ/T 86.
8.2.3 Harmless requirements for aerobic composting and compost products shall meet the requirements of relevant standards such as GB 7959 and GB 8172.
8.2.4 Bulk composting products after removing impurities may be used for greening or as soil modifier.
8.2.5 In accordance with the nature of the soil and the needs of users, the bulk products are added into N, P, and K additives to make organic and inorganic compound fertilizers. Additives shall be mixed uniformly with the original materials and meet the relevant standards.
as roadbed materials and backfills, their quality shall meet the road design requirements.
9.3 The waste incineration slag sorted out can produce aggregates, whose quality shall meet the requirements of GB/T 25032.
9.4 When the inorganic materials such as broken bricks and stones which are sorted out meet the requirements of JCJ 53, they can be used as concrete aggregates.
10 Incineration
