1、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 starte
2、d trying on this a decade later. Up to Jan 7, 2009, the Ministry of Environmental Protection of the Peoples 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 b
3、eing 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.Its a typical industry park wit
4、h 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
5、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. Th
6、e region of QIP is seriously polluted. QIP produces 27.7biliion m3 e emissions including 71,700 ton of SO2, discharges 5.1 million tons of waste water, and more than 1.37 million tone of industrial wastes residue waiting to be treated, yearly! The pollution factor of chromium, mercury, and lead for
7、local vegetables are 64.11, 185.8, and 66.01 that means the whole area is not proper for agriculture inside out.,IPE,CAS,Qingshuitang Case (basic situations),IPE,CAS,Qingshuitang Case,There are not much industrial networks for energy exchanging and material cascade using. The relationship between di
8、fferent industries is not so close. There is nearly no industrial symbiosis phenomena or exist in low level. The material metabolizing between different industry is incompact. Quantity of useful material treat as wastes for technical, economic, and policy reasons Products in bottom of industry value
9、 chain. There are many small plants, they symbioses as louse to mammal, eat wastes or intermediate products of big plant, share wasted energy with host. But they are small and technically laggard; they contribute most of pollution with high resource consumption.,IPE,CAS,Qingshuitang Case (symbiosis
10、networks),IPE,CAS,Specific situation of smelting industry,IPE,CAS,NONFERROUS METALS,The energy consumption of electrolytic lead downs to 0.594 tce/t-e-lead（the figure of 2004 is 0.792 tce/t-e-lead) The energy consumption of electrolytic zinc downs to 1.670 tce/t-e-zinc (the figure of 2004 is 2.227 t
11、ce/t-e-zinc) Fresh water consumption low than 1 200m3/Million Yuan output value The ratio of Process water recovery is up to 85%; The ratio of Rare metals recovery and utilizing is more than95%; and the ratio of usual smelting slag is 90%. About 2 billion Yuan gains from comprehensive utilization of
12、 waste recycling of valuable metals; over 400million Yuan achieved from utilization of industrial “three wastes”; recycling of wasted material worth more than 100million in this industry park. Every year, QIP decreases 5 million tons of industrial waste water, and 20 ton slag of lead, zinc and chrom
13、e. The lead concentration of dust is now lower than 0.27mg/m3. Releasing 22.68 hectares of land taken by slag.,IPE,CAS,Specific situation of chemical industry,IPE,CAS,Chemical industry symbiosis,Energy consumption is low than 200.0tce per Million Yuan output value Fresh water consumption is low than
14、 1 000m3 per Million Yuan output value The ratio of Process water recovery is up to 85%; The utilizing ratio of chemical industrial wastes is 85%. The emission of fumes will decrease 75%. The emission of SO2 The utilizing will decrease 80% .,IPE,CAS,Specific situation of S treatment,IPE,CAS,Centrali
15、zed SO2 tail gas treatment system have great effect on decrease SO2 emission. Every year, this system decreases SO2 30 000ton. (calculated from blast furnace tail gas, volatile furnace tail gas and Fuming furnace tail gas ). The element S comprehensive utilizing as sulfur did not considered in this
16、figure statistics,Qingshuitang Case(supporting),Environment is the base of living and developing. The layout programmed 8 key program of environmental rehabilitation. Five for water pollution prevent and control, two for SO2 pollution control, and one for solid wastes disposal. The cognitive of value and social behaviors of circular economy help the transition to circular economy society. Specifically, the developing of tertiary industry, circular economy technology information pla
