General survey of the circular economy development in China
Key provinces and cities
10 provinces and cities (such as Shandong province, Liaoning Province and Jiangsu province) were chosen as the experimental units, including resource-based, resource-poor, and other types.
Industry parks
13 industry parks were chosen as the experimental units, including national and provincial development zones, heavy and chemical industries concentration zones, and agricultural demonstration zones.
Key industries of high-consuming and heavy-polluting
7 key industries were chosen, including steel, non-ferrous metals, coal, power, chemical, building materials, light industry; pilot job was carried out in 42 enterprises.
Key areas of resources recycling
4 key areas were chosen, including recycling network construction, waste metals recycling, e-waste recycling, and remanufacturing; pilot job was carried out in 17 enterprises.
Achievements of circular economy in China
Recycled industrial solid waste accounts for 67%, up to 1.6 billion tons
per year; recycled hazardous waste accounts for 62%, up to 10 million
tons per year.
0.34 billion tons of coal were saved by the implementation of 10 energy-
saving key projects.
Coal consumption of power plant was reduced by 10.0%, from 370 g to
333 g coal per kilowatt-hour; energy consumption of steel plant was
reduced by 12.8%, from 694 Kg to 605 Kg coal; energy consumption of
cement plant was reduced by 24.6%.
Qingdao
Located in the south of Shandong peninsula, bordered on the Yellow sea
key port and tourist city Total area : 10,000 square kilometers,
population: 8.6 million Home appliance, basic chemical
industry, light industry, textiles, machinery manufacture are main industries
It is inevitable to develop the resource circulation for sustainable development

<Notice on comprehensively promoting the clean production>, < Implementation for
resource conservation campaign project in Qingdao>, <Opinion about developing the
circular economy in Qingdao>, and other official files were issued successively to give
tax preference to the projects regarding energy saving, and waste recycling.
Policy system to promote the development of circular economy
Industry structure analysis and resourcfulization potential evaluation are the basis for solid waste recycling
Comprehensive recycling of main industrial solid waste, such as carbide slag and white mud, was implemented in Qidao
Solid waste information exchange platform and E-waste recovery network were constructed, playing the important role in the circular economy development
Environmental safety in the resourcfulization process must be paid much attention
