We need good incentives with a system that self-corrects; we need to stop playing whack-a-mole with easily-known-ahead-of-time problems and implement good systems.
Modern island nations (Japan being one of the first) have been doing clean incineration through Arc Reactors / Plasma gasification for energy for decades.
