Under　the　environmental　sustainability　concept,　landfill　leachate　concentrate　can　be　up-cycled　as　a　useful　resource.　Practical　strategy　for　effective　management　of　landfill　leachate　concentrate　is　to　recover　the　existing　humate　as　fertil-izer　purpose　for　plant　growth.　Herein,　we　designed　an　electro-neutral　nanofiltration　membrane　to　separate　the　humate　and　inorganic　salts　for　achieving　a　sufficient　humate　recovery　from　leachate　concentrate.　The　electro-neutral　nanofiltration　membrane　yielded　a　high　retention　of　humate　(96.54　%)　with　an　extremely　low　salt　rejection　(3.47　%),　tremendously　outperforming　the　state-of-the-art　nanofiltration　membranes　and　exhibiting　superior　promise　in　fractionation　of　humate　and　inorganic　salts.　With　implementation　of　the　pressure-driven　concentration　process,　the　electro-neutral　nanoltration　membrane　enriched　the　humate　from　1756　to　51,466　mg　&　BULL;L-1　at　a　fold　of　32.6,　enabling　90.0　%　humate　recovery　and　96.4　%　desalination　efciency　from　landll　leachate　concentrate.　Furthermore,　the　recovered　humate　not　only　exerted　no　phytotoxicity,　but　also　signicantly　promoted　the　metabolism　of　red　bean　plants,　serving　as　an　effective　green　fertilizer.　The　study　provides　a　conceptual　and　technical　platform　using　high-performance　electro-neutral　nanoltration　membranes　to　extract　the　humate　as　a　promising　nutrient　for　fertilizer　application,　in　view　of　sustainable　landll　leachate　concentrate　treatment.
