Aware that the health issues linked to pollution were becoming increasingly urgent for the Chinese population, the Chinese authorities launched an environmental policy. With the manager of the SCIP (Shanghai Chemical Industry Park), they contacted SUEZ in 2002 for the design and build of a water treatment plant on the industrial site. In the end SUEZ were given the task of managing the hazardous waste on the site, supplying drinking water and industrial water, and treating its particularly polluting effluent.
To respond to the request of the site, SUEZ extended its project to the production of a very high temperature hazardous waste incinerator (1100°C).Thanks to a joint venture set up with the industrial estate in 2003, waste processing was up and running by 2006!
What challenges did the project present? To build and operate an hazardous waste incinerator which meets the EU standards in China. To succeed we recruited and trained local staff. We managed to implement cutting-edge technology based on equipment produced on-site. However, our response goes beyond just technological solutions. We offer a chain of services: logistics support, transport, packaging and labelling, training, etc.
We designed a system adapted to this exceptional industrial site: almost 30 km² of fresh material arriving on a regular basis... In the incinerator, two lines with a capacity of 30,000 tonnes were built first. To absorb the growing needs of the industrialists, they will be supplemented by a third, soon-to-be-finished line with a capacity of 60,000 tonnes.
The combustion of the hazardous waste produces energy which is recovered and reused in the form of steam, partially replacing fossil fuels. The smoke is treated and filtered.
Each factory on the site is connected to the wastewater treatment network. The water is reused and feeds the demineralised water production plant which can produce 200,000 m3 of industrial water and 7,000 m3 of drinking water per day.
The SCIP Water Research Center (SWRs), the partner laboratory situated at the heart of the site, works on developing technologies to treat and reuse wastewater. To this end it regularly analyses the waste processed and puts forward new processes.
The SUEZ wastewater treatment and waste processing solutions have made the SCIP petrochemical estate more competitive, attractive and durable thanks to cleaner production which saves the resource.
Inserted into the Chinese industrial fabric, the traceability and safety of which can improve still further, the SCIP industrialists can turn to SUEZ for 100% reliable solutions, precluding any risk to their image.
