Microfiltration membranes derived from semi-crystalline polymers face various challenges when synthesized through the extrusion–casting technique, including use of large quantities polymer, long casting times, and generation substantial waste. This study focuses on synthesizing these using spin-casting followed by stretch-induced pore formation. Recycled high-density polyethylene (HDPE) virgin powder, combined with a calcium carbonate filler, were used as source materials for membranes. The influence polymer-filler ratio without stretching morphology, tensile strength, water flow rate was investigated. Optimal conditions determined, emphasizing balance between structure mechanical integrity. permeable membrane possessed mean diameter 500 nm, exhibited strength measuring 32 MPa, allowed to at 19 ml/min, had contact angle 126°. These effectively eliminated suspended particles water, their performance evaluated against that commercially available research outlines synthesis route microfiltration tailored plastic forms, utilizing technique.
