Waste　classification　is　to　reduce　solid　waste　and　its　associated　environmental　pollution.　This　paper　applied　bibliometrics　to　assess　publications　related　to　classification　technology　of　domestic　waste　from　2000　to　2019.　A　total　of　466　publications　were　retrieved.　The　results　showed　the　number　of　citations　and　papers　increased　rapidly.　The　major　publication　type　regarding　waste　classification　technology　is　article　and　English　is　the　primary　language　for　academic　communication.　The　research　is　multidisciplinary　and　interdisciplinary,　and　its　research　directions　are　mainly　divided　into　＂Engineering,＂　＂Environmental　Sciences　Economics,＂　and　＂Chemistry.＂　It　was　identified　that　Waste　Management　(85)　published　most　of　papers　in　this　topic.　Meanwhile,　China　(93)　contributed　the　most　of　publications,　followed　by　the　USA　(42),　France　(40),　Japan　(36),　and　Italy　(28).　European　countries　are　in　the　leading　position　in　the　study　of　garbage　classification　technology.　Plastics　and　waste　metals　were　the　existing　focus　of　waste　classification　technology,　and　waste　identification　and　classification　has　become　an　important　classification　method.　In　addition,　we　also　summarized　the　current　mainstream　technology　progress　and　possible　research　challenges.
