Geosynthetics for Tianjin Eco-City (China)
Close to Tianjin (China), which lies to the southeast of the capital city of Beijing, a new city is emerging, with a surface area of 34 km2. It is based on sustainability. TenCate Geosynthetics made a key contribution to the transformation of an over 30 years old contaminated wastewater impoundment into the pristine Qingjing Lake, one of the constituent parts of Tianjin Eco-City. In November 2012 this contribution garnered the Outstanding Achievement Award for the business unit Water & Environment of TenCate Geosynthetics from the Industrial Fabrics Association International (IFAI).
The area with TenCate Geotube® containers
Tianjin Eco-City is a new sustainable city in the making. It is a strategic cooperation between Singapore and China. By the year 2020 the once so desolate location with pockets of polluted area will be a hive of sustainable business activities and home to 350,000 to 400,000 people. Tianjin Eco-City is to become a successfully growing city that is socially harmonious, environmentally friendly and efficient in resource management. Not only will the living environment be drastically improved, the new city will also serve as a role model in China for future living environments and sustainable developments.
Layers with filled TenCate Geotube® containers
TenCate Geotube® technology was used in transforming a contaminated wastewater impoundment near Tianjin into Qingjing Lake. Some 18,700 metres of containers based on this technology were used for cleaning (dewatering and storing) contaminated dredged slurry. The containers, ranging from 27.5 to 30.5 m in circumference, were filled with contaminated sediments, which were then dewatered. The containers were stacked in four layers, capped and integrated into the landscape, thus forming a 9m-high mound with a footprint area of 12 ha in this city of 34 km2.

TenCate Geosynthetics has won an IFAI award every year for the past eight years, and this is the fourth time the business unit Water & Environment has been so distinguished. Increasingly the market is recognizing the positive value of geotextiles when it comes to sustainability (life span and only minor environmental impact).
