The　annual　output　of　domestic　waste　has　exceeded　400　million　tons　in　China　since　2016,　which　causes　an　urgent　demand　on　harmless　disposal　in　the　current　rapid　process　of　urbanization.　Compared　with　traditional　disposal　means　(e.g.　incineration　and　landfill),　co-processing　with　cement　production　seems　to　be　a　better　chose　to　meet　the　requirements　of　domestic　waste　treatment　(i.e.　harmless,　volume　reduction,　waste　utilization).　However,　co-processing　technology　also　has　some　negative　impact　(e.g.　extra　energy　consumption　for　pretreatment　of　domestic　waste),　so　the　environmental　feasibility　of　domestic　waste　co-processing　in　cement　kiln　should　be　verified.　In　this　paper,　the　influences　caused　by　domestic　waste　co-processing　on　the　cement　clinker　products　including　resource/energy　consumption,　as　well　as　the　pollutant　emissions　were　quantify　based　on　the　investigation　of　typical　plants　in　China.　Moreover,　the　environment　impact　between　landfill　treatment　and　co-processing　scenario　were　compared　using　life　cycle　assessment　(LCA)　method.　The　result　shows　that　the　energy　consumption　and　CO2　emission　per　ton　cement　clinker　production　increased　by　3.6%　and　0.8%　after　co-process　domestic　waste,　respectively.　Furthermore,　compared　with　sanitary　landfill　treatment,　the　co-processing　in　cement　kiln　will　increase　the　impact　of　FFP,　but　reduce　GWP　and　HTP　impacts,　especially　significantly　decrease　the　impact　of　LOP　and　SOP,　bring　in　a　good　beneficial　on　material　saving　and　energy　saving.　©　2020　Trans　Tech　Publications　Ltd,　Switzerland.
