Energy and water saving potentials in industrial parks by an infrastructure-integrated symbiotic model

•An infrastructure-integrated industrial symbiosis (IS) model adaptive to industrial parks is proposed.•A quantitative and qualitative match-making method is established to uncover symbiotic cooperation.•111 parks are considered to quantify benefits associated with IS between WWTPs and energy facilities.•Potentials of water-energy-saving and GHG mitigation of IS are quantified with life cycle thinking.
