As an advanced urban management concept, " Zero-waste City " aims to promote the source reduction of solid waste and resource utilization, and promote the formation of green development mode and lifestyle. Plastic waste is the key and hot topic in the construction of "Zero-waste City". Sino-Norwegian cooperation project on capacity building for reducing plastic and microplastic pollution (SINOPLAST) is an international cooperation project approved by the Ministry of Commerce of China and Norwegian Ministry of Foreign Affairs. Ministry of Ecology and Environment (Department of International Cooperation) is the applicant and BCRC China is the executive entity. SINOPLAST has carried out research on plastic reduction on pilot zero-waste cities, which can strongly support the formulation of policies and standards by government. This meeting will demonstrate the outcomes of plastic reduction under SINOPLAST for representative "Zero-waste Cities", and promote the construction of "Zero-waste City".
