China spelled out details of its initiative to ban imports of polluting garbage, issuing an action plan on Thursday that increases the limits on the types and amounts of the waste.

The central government has approved the action plan, to be completed by the end of 2019, that bans imports of foreign waste and improves the domestic recycling industry.

China will stop accepting shipments of various types of plastics, unsorted paper, textiles and vanadium slag by the end of this year. The list of banned items will likely grow longer as more types of solid waste are added, a State Council statement indicates.
