TWO giant pools are abandoned at the edges of a land that houses a coal-fired steam power plant (PLTU) in Karangkandri, Cilacap, Central Java. Right off the coastline and not far from the estuary of Sungai Serayu, the two pools were used to collect coal combustion residues, in the form of fly ash and bottom ash. “In the past, the waste was dumped there. But they are no longer used after the people’s protests,” said Awaluddi
