Abstract Polyethylene (PE), including high‐density polyethylene (HDPE) and low‐density (LDPE), makes up a significant part of post‐consumer plastics in municipal solid waste, presenting challenges for traditional recycling methods due to wide range melt flow properties poor interfacial adhesion between the different resin, which often leads low quality products (downcycling). In this study, method is proposed modify molecular structure PE (rHDPE rLDPE) their blends by using straightforward organic peroxide crosslinking technique with 1 phr dicumyl (DCP). Different rHDPE/rLDPE blend weight ratios (0/100, 20/80, 40/60, 50/50, 60/40, 80/20, 100/0) were prepared combination co‐rotating twin‐screw extrusion pulverization. The final parts produced via rotomolding where both forming processes occurred concurrently. Subsequently, materials characterized terms chemical, thermal, mechanical properties. It was found that tensile strength (228%), modulus (345%), flexural (145%), (251%) increased 80% wt. rHDPE (x‐rHDPE). Conversely, gel content 17%, thermal resistance 37.2%, impact 93% rLDPE (x‐rLDPE). can be concluded balance occurs as addition DCP improved blends. This innovative approach represents simple upcycle mixed (PE) streams, especially applications. also offers promising avenues sustainable waste management material reuse.
