Back to sectors
Industries now need to rise to a combination of major environment, regulatory, social, economic, and operational challenges. As a result, they have begun to look beyond simple service solutions in search of a truly creative partner able to innovate. This is the kind of ongoing challenge at which Veolia excels in. Veolia has developed innovative, competitive solutions and top-level expertise that manage industries’ entire water cycle: from abstraction or desalination to producing process water through to treating and recycling wastewater and sludge.

In December 2001, the municipal government in Chongqing, China, gave its go-ahead for the creation of the Chongqing Changshou Chemical Industrial Park, initially spanning 31.3 square kilometers. The city’s goal was to develop an integrated industrial park that would bring together all of the companies in the region that specialize in gas chemistry, petrochemicals, raw materials, fine chemicals and new materials.

By the start of 2014, 81 companies, including a number of Fortune 500 firms, had established operations at the park.
Veolia (Changyang) was commissioned to design, build and operate a cogeneration plant capable of meeting the park’s steam and electricity needs.
