Initially, poly (methyl methacrylate) polymer dope solution with MIL-53(Al) dispersed in the matrix was subjected to electrospinning to get a novel nanofiber. The linker terephthalic acid, here was derived from waste PET bottles. Both the MOF and nanofibers were characterized using BET, FTIR, zeta potential, and XRD. The optimized nanofibers were used as additives in the TFC in different weight percentages using synthesized porous PVDF as support. TFC Membranes were analyzed by pure water flux, chlorpyrifos, and atrazine rejection. MPM-2 with 0.05 wt% nanofiber gave a pure water flux of 18.6824 Lm?2h?1. The rejection of chlorpyrifos (a hazardous pesticide) was 86.8 % for MPM-2 membranes and atrazine (a herbicide) gave rejection of 60.48 %. Further, membranes gave excellent antifouling property with FRR of 95.45 %. © 2025 Elsevier LtdBioremediationComposite membranesEffluent treatmentHerbicidesInsecticidesNafion membranesNanocomposite filmsNanocomposite thin filmsPlastic bottlesChlorpyrifosEffective removalsFlat sheet membranesP.V.D.FPET bottlesPoly(vinylidene fluoride)Pure waterThin film compositesWaste PETWater fluxNanofibers
