The thing is, virtually every single incineration plant also generates electricity, typically at smaller scales than dedicated plants to serve smaller regions, but distributed/decentralized generation is a big win for resilience of the grid overall. Also please provide at least one citation where "maybe we'll totally reverse the negative effects of this thing we put into our environment" has been fulfilled. I can only think of failures to live up to that expectation: PFAS, microplastics, oil spills, etc.
