Based on your inputs, the optimum end-of-life scenario for your used membrane is:
Disposal in local landfill
Energy recovery through incineration
Energy recovery though syngas production
Energy recovery through use as a coke substitute in Electric Arc Furnaces
Material recycling
Chemical conversion to an ultrafiltration membrane and then reuse
Direct membrane reus
Direct reuse as a high quality seawater RO membranes
Direct reuse as a high quality brackishwater RO membranes
Direct reuse as a medium quality brackishwater RO membranes
Direct reuse as a low quality brackishwater RO membranes
Direct reuse as a medium quality nanofiltration membranes
