5 Requirements for recyclability and recoverability rates of the vehicles
5.1 Recyclability rate requirement for vehicles
The recyclability rate of vehicles in Categories M1 and N1 shall not be less than 85%.
5.2 Recoverability rate requirement for vehicles
The recoverability rate of vehicles in Categories M1 and N1 shall not be less than 95%.
6 Calculation method for recyclability and recoverability rates
6.1 General
6.1.1 The recyclability and recoverability rate shall be calculated based on the vehicle material data collected from the supply chain and proven recycling technology.
6.1.2 Plastic, rubber, and thermoplastic elastomer components shall be marked with the material type on the surface in accordance with the requirements of QC/T 797. Components of other material types shall be marked with the recoverability mark on the exterior surface, or such information about recoverability and relevant technology of the parts shall be described in technical documents such as the dismantling manual of end-of-life vehicles in accordance with the requirements of GB/T 26988, where the dismantling manual of end-of-life vehicles shall be compiled in accordance with the requirements of GB/T 33460.
6.1.3 The calculation of the recyclability and recoverability rates is carried out through the following four steps:
