Setting our sights on enhancing the productivity of resources and raising the rate at which they are recycled, we will optimize the spatial layout of industrial parks, and retrofit these parks to facilitate circular production. Circular production in enterprises and circular organization of industries in these parks will be encouraged as well, and arrangements will be made for enterprises to conduct retrofits for clean production. We will promote the comprehensive utilization of waste, cascading use of energy, and circular use of water resources. To be specific, we will facilitate the recycling of residual heat and pressure as well as waste gas, liquid, and slag from industrial processes, and actively expand the application of centralized gas and heating supply. We will set up platforms for sharing infrastructure and public services, and strengthen the management of material flow in parks. By 2030, all key industrial parks at the provincial level or above will be upgraded to support circular operations.
