This　paper　uses　LCA(Life　Cycle　Assessment)　to　make　a　quantificational　analyse　for　the　environment　impact　of　hollow　brick　produced　by　the　waste,　the　environment　impacts　come　from　the　mining　of　raw　materials　to　the　product　process.　The　results　show　that　the　greatest　impact　on　the　environment　is　the　greenhouse　effect　in　the　life　cycle　of　the　hollow　brick　produced　by　the　waste,　which　possess　24%　of　the　total　environmental　impact,　while　the　largest　environmental　impact　in　the　whole　process　is　sintering　the　brick,　accounting　for　73%　of　the　total　environmental　impact.
