Nantong Economic and Technological Development Area: Finding the way out for hazardous waste in Nantong

Nantong Economic and Technological Development Area (NETDA) is one of the first batch of the 14 economic and technological development zones approved by the State Council in December 1984, covering a total area of 146.98 km2., and awarded "ISO14000 National Demonstration Zone" by the Environmental Protection Ministry of China. In 2014, SUEZ, Shanghai Chemical Industry Park Investment Company, and NETDA Corporation set up a joint venture to provide hazardous waste treatment service for the industrial clients in Nantong.
The mission

Find the way out for hazardous waste in Nantong

NETDA, as one of the first approved and established national economic and technological development zones in China, has now evolved to six industry clusters after years of development, i.e., modern equipment manufacturing, new materials, fine chemicals, new medicine, new energy and modern services. Many sectors in NETDA has reached the world advanced level in terms of technological level and manufacturing capacity.


However, what accompanies industrial development is inevitably the production of industrial waste, including a considerable number of hazardous waste being corrosive, flammable, toxic, etc. Therefore, Nantong is badly in need of a modernized high-standard hazardous waste treatment facility to minimize the industrial risks, promote further environmental improvement and development of green low-carbon economy.

Our solution
The hazardous waste treatment project that SUEZ invests, designs, constructs and manages is primarily applied to treat hazardous waste produced by the local industrial enterprises in Nantong, and also to treat 3,300 tons/year of medical waste, the group's first ever that integrates both hazardous waste treatment and medical waste treatment. The project strictly adheres to China and EU emission standards and is managed according to the highest international safety and environmental standards. The energy generated during the incineration of waste is recycled to produce steam, which is then used as a green energy supply for enterprises of NETDA.
The results
  • SUEZ hazardous waste treatment project in Nantong is the largest individual installation of shredding & mixing hazardous waste incineration in Jiangsu Province, of which the annual treatment capacity reaches 30,000 tons/ year as to the first phase, and will achieve 60,000 tons/year when the second phase is completed.
  • The project complies with stringent emission standards to minimize the environmental impacts, for example, the off-gas meets the EU emission standard, accepting 24-hour on-line monitoring by Environmental Protection Bureau of Jiangsu Province; the dust and ash residues upon incineration are specially treated and landfilled in carefully selected, monitored and qualified sites.
  • In addition, the project is equipped with an energy recovery system, which makes use of the heat generated during incineration to produce steam to supply to the medical waste workshop and industrial enterprises of the park, saving 12,000 tons/year of standard coal.
