China to curb pollution by non-ferrous metals sectors, lead battery facilities

China has proposed stricter limits on heavy metal pollution, targeting the non-ferrous raw materials sectors involved in processing, lead-battery manufacturing and galvanizing.

By 2025, the targeted sectors will have to reduce heavy metal emissions by 5% compared with 2020 levels. The heavy metal pollutants included are lead, mercury, cadmium, chromium, arsenic and thallium, the country’s environmental ministry said on Monday November 22.
The list of sectors subject to the new heavy metal pollution targets are: non-ferrous metal mining (including associated minerals), mined material processing (copper, lead, zinc, nickel, cobalt, tin, antimony and mercury), non-ferrous and industrial metal smelting (copper, lead, zinc, nickel, cobalt, tin, antimony and mercury smelting, including secondary smelting), lead-acid battery manufacturing, and electro-galvanizing.

Such increased environmental scrutiny typically means the phasing-out of old facilities, which in turn affects metal output before any replacements can be built...
