And combined with the specific circumstances of Shanghai Chemical Industry Park, the fundamental of cyclic economy theory (5 integrity area:product project integrity, utility integrity, logistic integrity, environment protection integrity and management service integrity), industry chain nodes, as well as the centralized supply system in the Park is studied. Also the technology analysis for the typical enterprise(Secco, Bayer, BASF, Tianyuan etc) are made, Based on the study, the major problems encountered in the further development of cyclic economy are raised and several appropriate measures are also proposed. |
