As　one　of　the　important　basic　raw　material　industries　in　China,　cement　is　widely　used　in　construction,　national　defense,　roads　and　other　fields.　Along　with　the　continuous　progress　of　the　sustainable　development,　cement　industry　is　under　the　change　stage　from　the　intensive　production　of　high　energy　consumption　and　high　pollution　to　the　environment　friendly　development　mode.　In　this　study,　an　environmental　impact　assessment　index　system　and　procedures　based　on　Life　Cycle　Assessment　method　were　established,　which　suit　for　cement　production　process.　The　research　of　environmental　impact　hotspot　identification　and　process　optimization　effect　evaluation　on　the　new　dry　cement　production　process　was　introduced.　Moreover,　quantitative　evaluation　and　comparison　for　technology　solutions　of　the　cement　kiln　co-disposal　of　sludge　and　household　garbage,　as　well　as　industrial　waste　in　place　of　raw　materials　were　carried　out　in　order　to　provide　guidance　for　accurate　quantification　of　environmental　burden　in　cement　production　process　and　eco-design　of　environment　friendly　waste-based　cement.　©　2016,　The　Editorial　Board　of　Materials　China.　All　right　reserved.
