In the sectors of waste and biomass to energy, some debatable paradigms persist both among the specialists and among the population, concerning the performances of a few energy options. The present article wants to give a contribution to clarify the debate related to three cases: (a) local impact of waste to energy plants, from conventional solutions to innovative ones (thermochemical processes); (b) local impact of Solid Recovered Fuel generation before energy exploitation; (c) local impact of combustion of wood. Three key articles have been selected from the Author’s production (more than one hundred Scopus indexed works) in order to perform a deeper analysis. Results demonstrate that, changing the perspective, some paradigms on the environmental performances of a few waste and biomass options for energy generation must be at least modified.
