Interpretation of the National Standard GB/T 19515—2023: Requirements and Calculation Methods for Recyclability Rate and Recoverability Rate of Road Vehicles

• • The standard mandates that for M1 and N1 vehicles, the recyclability rate must be ≥85% and the recoverability rate must be ≥95%, aligning with EU Directive 2005/64/EC and ECE R133 requirements. • • In 2024, M1 vehicles consumed an average of 1,333.5 kg of metals, 271 kg of plastics, and 77.4 kg of rubber per vehicle, leading to annual consumption of over 3.6×10^7 t of metals, 7.4×10^6 t of plastics, and 2.0×10^6 t of rubber, underscoring the urgent need for effective recycling. • • The calculation method is based on four stages of end-of-life vehicle processing: pre-treatment, dismantling, metal separation, and non-metallic residue treatment, with specific weight determinations for components such as fluids, batteries, oil filters, tires, and catalytic converters. • • The standard has evolved from GB/T 19515—2004 (identical to ISO 22628:2002) to the 2023 revision, incorporating updates to reflect technological advancements and changing vehicle designs, and future revisions will expand vehicle types and refine material identification and connection structures.
