Suez NWS and SE Environment partner in Shenzhen sludge-to-energy plant

Hong Kong-based Suez NWS Ltd and SE Environment, a subsidiary of Shenzhen Energy Group Co., Ltd have signed a shareholder agreement to establish the joint venture (JV) SE Suez Environmental Technology Co., Ltd, which will be in charge of managing the “Shangyang Project” for the treatment and energy recovery of sludge in the city of Shenzhen, China for a contract duration of 30 years.

According to a statement, the “Shangyang Project” is the largest sludge recovery and treatment facility in the City of Shenzhen, southern China. With a capacity of up to 800 tonnes of sludge per day, it will optimise the treatment of sludge from more than ten municipal wastewater treatment plants (WWTP) in the Longgang district and the downtown Shenzhen.

We are very pleased to cooperate with Suez NWS and jointly operate and manage the Shangyang Project, which offers a lasting solution for 30 percent of the sludge in the city of Shenzhen. It’s a great responsibility for us. We will put our expertise and professionalism to work to ensure the quality and safety of the operation, said Xiong Peijin, Chairman of the Board of Shenzhen Energy Group Co, owner of SE Environment, the stakeholder in SE Suez Environmental Technology.

Built by Suez NWS, the Shenzhen Shangyang sludge treatment plant is the first sludge-to-energy recovery facility in Shenzhen. It will use the “Thermylis” technology, a technology developed by Suez, for the first time in China.

Successfully deployed in more than 40 plants built by Suez in Europe and North America, Thermylis significantly reduces energy consumption in order to minimise sludge volumes in an efficient, economical and environmentally-friendly manner.

Having successfully completed the construction of the Shenzhen Shangyang sludge treatment plant, we are proud to operate it with SE Environment. This new partnership will further strengthen our ties with local actors, to continue to assist Shenzhen Government to achieve their ambitious environmental goals, said Marie-Ange Debon, Group Deputy CEO in charge of International segment-

Suez NWS is a pioneer and a leader in China’s sludge treatment industry. Since the Group introduced Suez’s patented technology “INNODRY 2E” in 2008, four sludge drying plants have been successively built in Chongqing, Suzhou and Yangzhou, ensuring the safe treatment of sludge from these three cities.

For the Group, this first application of its Thermylis technology in the Shangyang Project is a showcase for future developments in China, to address the need for large-scale treatment of municipal sludge in rapidly growing cities like Shenzhen.
