The　development　of　sustainable　techniques　to　produce　high-performance　zeolite　is　essential　to　achieve　green　production　in　industry.　Herein,　we　report　an　eco-friendly　route　to　synthesizing　hierarchical　Beta　zeolite　from　kaolinite　and　recycled　mother　liquor.　The　results　reveal　that　the　unutilized　species　(such　as　silicon　species　and　Na+)　in　mother　liquor　stayed　in　a　stable　concentration　during　eleven　recycled　experiments.　Moreover,　the　synthesized　Beta　zeolites　still　have　comparable　physicochemical　properties　and　catalytic　performance　in　the　esterification　of　levulinic　acid　with　ethanol　over　the　initial　zeolite　although　eleven　recycled　experiments.　Life　cycle　assessment　exhibits　that　the　synthesis　of　Beta　zeolite　with　recycled　mother　liquor　can　reduce　global　warming　potential　by　23%　and　resource　depletion-water　use　by　36%　compared　to　that　without　recycled　mother　liquor.　This　quantitatively　demonstrates　that　the　approach　proposed　in　this　work　is　really　a　sustainable　one,　extremely　increasing　the　utilization　efficiency　of　raw　materials　and　decreasing　the　environmental　burden.　©　2024　Institute　of　Process　Engineering,　Chinese　Academy　of　Sciences.
