The construction of Tianjin, an eco-city developed by China and Singapore, has just broken ground. The 30 square kilometer site will eventually house 350,000 people in an effort to balance active commerce and environmentally conscious living.

The Tianjin Eco-City site is atop a series of low-quality salt flats located about 40 kilometers from the present city of Tianjin. Since these salt flats cannot be used for agriculture, as Tree Hugger reports, they will be reclaimed to build the Tianjin Eco-City. China is counting on Singapore to help the Tianjin development run solely on clean energy--both solar and wind power will be used. In addition, Tianjin will recycle rainwater, desalinize seawater and utilize greywater recycling.
