Wael Al Awar and Kenichi Teramoto, principal architects at waiwai, enlisted the scientific knowhow of universities in the UAE and Japan to create a cement made using brine generated by the UAE's desalination plants, which remove salt from seawater. They were inspired by the UAE's mineral-rich sabkha -- salt flats that are part of the country's wetlands. "It a huge area ... that's often overlooked," Al Awar told CNN.
