Plant-scale hyperthermophilic composting of sewage sludge shifts bacterial community and promotes the removal of organic pollutants

•Hyperthermophilic composting enhanced the removal of toxic organic pollutants.•Hyperthermophilic composting reduced bacterial diversity and shifted its structure.•Extremophilic and heat-resisting Deinococcus-Thermus is predominant during composting.•Sludge composting enriched the bacterial functions related to xenobiotics degradation.•The PICRUSTs revealed the promotion of pollutant degradation by bacterial community. The dissipation of toxic organic pollutants during plant-scale hyperthermophilic composting and the influence of microbial community remain unclear. The results of plant-scale hyperthermophilic composting of municipal sludge with green waste showed that the residual concentrations of polyaromatic hydrocarbons, phthalates, polybrominated diphenyl ethers were
