Epic Cleantec’s soil amendment Photograph: Matt Simon Researchers are experimenting with using the same technique for wastewater solids, basically turning sludge into a solid product. “If you do pyrolysis—because it’s thermochemical, it’s a heated process—you kill these bacteria, kill these pathogens, kill these viruses. It’s much cleaner,” says engineer Fengqi You, who studies wastewater at …
Russia battered Kyiv and Kharkiv with missiles and drones overnight, killing at least four people and injuring 92 more, after President Vladimir Putin said he was “seething” and would “intensify attacks” on Ukraine.
