Polluters need to watch out for an eye in the sky as drones have
helped China's ministry of environmental protection (MEP) detect factories
flouting environmental laws in one of China's most polluted provinces. The
ministry dispatched drones in March to Handan city in north China's Hebei
province, where they uncovered violations, including excessive emissions and
inadequate waste processing, state-run Xinhua news agency repported. Several
companies missed deadlines for putting anti-pollution facilities in place and
others do not have any waste processing facilities, the ministry said, quoting
monitoring results from the drones.
