* The prominent problems including upgrading cleaner production technology of non-ferrous melting industry, deep processing and integrated utilization of precious metal from slag of lead and zinc, regulating structures and industry chain of chemical industry, assimilating and integrated utilizing solid wastes of fly ash and calcium carbide slag. * * * * * * * * * Development of circular economy in heavily polluted Industry Park— a case study in China Dr. Huiquan LI, Hui Zhang Institute of process engineering, Chinese Academy of sciences(IPE, CAS) IPE,CAS EIP in China Since 1990s, many developed countries practiced lots of EIPs or eco-communities. China started trying on this a decade later. Up to Jan 7, 2009, the Ministry of Environmental Protection of the People’s Republic of China (MEP) had issued 33 constructing layout of EIPs of state experimental demonstration. The legislation of ‘Circular Economy Promotion Law of the Peoples Republic of China’ have being implemented in Jan. 2009. IPE,CAS Framework for EIP design IPE,CAS Qingshuitang Case Qingshuitang Industry Park (QIP) locates at northwest of Zhuzhou city，Hunan Province in middle part of China. There are more than 100 plants crowed in the land less than 10.2 km2.It’s a typical industry park with dense chemical and metallic enterprises. The leading industries of QIP are primary processing of non-ferrous metal industry and basic chemical industry with high energy consuming and high pollution, but on the bottom of industry value chain. There are several representational plants big enough as leading of industry. These run with traditional technology and old apparatuses. IPE,CAS Qingshuitang Case Why is QIP interesting? Historically, QIP was firstly established by the state as smelting and chemical base in 1950s. But the development of QIP was lagged for the reason of developing mode. The region of QIP is seriously polluted. QIP produces 27.7biliion m3 e emissions including 71,700 ton of SO2, discharges
