Synthesizing　zeolites,　which　are　important　materials　used　in　the　petroleum　and　chemical　industries,　from　natural　aluminosilicate　minerals　has　been　qualitatively　recognized　as　a　greener　approach　compared　to　that　from　traditional　Si-　and　Al-containing　chemicals;　however,　studies　on　the　quantitative　environmental　impacts　are　still　lacking.　Herein,　life　cycle　assessment　(LCA)　and　green　metrics　(atom　economy　and　environmental　factor)　were　employed　to　comparatively　assess　the　life　cycle　environmental　impacts　of　zeolites　synthesized　from　chemicals　and　natural　minerals　at　the　industrial　scale.　The　values　of　seven　LCA　impact　categories　and　sensitivity　analysis　between　them　were　thoroughly　compared.　The　results　showed　that,　for　each　category,　the　synthesis　from　natural　minerals　has　lower　environmental　impacts　to　varying　degrees　than　that　from　chemicals.　Further　efficiency　analysis　of　zeolite　manufacturing　technologies　by　green　metrics　indicated　that　the　synthesis　from　natural　minerals　outperforms　that　from　chemicals　in　terms　of　the　resource　utilization　rate.　The　quantitative　results　indicate　that　significant　benefits　stem　from　the　replacement　of　raw　materials　from　chemicals　to　natural　minerals.　This　work　may　provide　a　basis　for　the　future　selection　and　upgrade　of　zeolite　production　processes.　©　2024　The　Royal　Society　of　Chemistry
