Shanghai Chemical Industry Park (SCIP): Reconciling economic growth and green growth

Shanghai chemical industry park (SCIP) is located in the south of Shanghai, north of Hangzhou Bay, with the management area of 36.1km², It is one of the world's largest integrated petrochemical bases. In 2002, SUEZ NWS signed a cooperation agreement with SCIP to provide integrated water supply and wastewater treatment services for industrial customers in SCIP.
The mission

SCIP is the first professional petroleum and fine chemical industrial park since the reform and opening up. SCIP acts as the center of six south industrial zones in Shanghai, it is also one of the largest investment industrial projects during the 10th Five Year Plan period. At present, many world class chemical companies such as Sinopec, Bayer, BASF, Evonik, Huntsman, Mitsubishi, Mitsui Chemicals set their business in SCIP.

 

Such large scale of production brings great challenges to environment, the water demand of chemical companies increases sharply, and the large amount of wastewater pollution concentration is also turning high, therefore, the professional integration of water services is significantly requested to achieve a harmonious development of chemical industry and environment with balanced production and the ecology.
