Abstract The automotive industry's pursuit of lightweight, high‐performance, and sustainable materials has driven interest in natural fiber‐reinforced thermoplastics. However, challenges such as moisture sensitivity, lower strength, fiber‐matrix compatibility hinder their widespread adoption. To address these constraints, this study developed compound formulations incorporating recycled waste components fibers alternatives to injection‐molded composites reinforced with long glass (LGF) for structural applications the industry. newly comprised PP by 40 wt% alkaline treated flax fiber (FF), 1 tire‐derived graphene nanoplatelets (GNP), 3 compatibilizer, resulting significant improvements flexural modulus surpassing both neat homopolymer (homoPP) (rePP) 202% 92.5%, 161.5% 54.7%, respectively. assess viability, mechanical, thermal, rheological properties were compared commercial counterparts used serial production. Furthermore, a comparative life cycle assessment evaluated carbon footprint different matrix types, revealing that rePP‐based formulation reduced CO 2 emissions 50% LGF/homoPP while achieving 7.2% weight reduction. This successfully demonstrates potential integrating waste‐derived reinforcements into composites, offering environmentally friendly alternative applications. Highlights Sustainable Flax upcycled GNP utilized lightweight composite fabrication Flexural strength significantly improved composites. Life Cycle Assessment performed emission reduction achieved using
