China's Power-Battery Recycling 2026: The First Year of Binding Rules, and a Disordered Urban Mine

On 1 April 2026, MIIT Order No. 73, issued jointly by six ministries, took effect, giving power-battery recycling in China its first binding regulation. It confronts a peculiar industry: whitelisted firms hold nominal capacity counted in millions of tonnes yet process only a fraction of it, and roughly eight in ten scrapped electric vehicles arriving at licensed dismantlers have no battery. This is not an industry short of capacity, but one short of order.
