Plastics are widely used in manufacturing various products due to their durability, strength, and low cost; however, they originate from nonrenewable sources. The growing interest developing environmentally friendly materials has driven research toward the incorporation of natural fibers recycled plastics. In Ecuador, Guadua Angustifolia Kunth (GaK) bamboo is usually as furniture construction materials. Therefore, this work aims reevaluate traditional use GaK fibers, exploring potentiality using chemically treated reinforcement material for thermoplastic composites. This study presents development composite based on high-density polyethylene (HDPE), HDPE (rHDPE), an experimental design that includes performing tension, flexural, impact tests obtain optimal formulation. composites were characterized optical microscopy, SEM, FTIR, DSC, TGA, EDX, followed by a life-cycle assessment (LCA). SEM images revealed morphological changes while TGA indicated significant mass loss degradation above 200 °C all DSC showed melting temperature approximately 133 samples. These results there will not be fiber during processing. highest maximum tensile strength achieved among optimization samples was 18.69 MPa. All increase Young's modulus, with enhancement up 204% compared pure HDPE, albeit marked reduction elongation percentage. flexural increased 17.84%, but decreased 83% fiber-matrix compatibility ductility composite, which allows it absorb less energy before fracture. formulation had 10% cellulose, 50% 40% rHDPE, exhibited 17.62 MPa, obtained mixture regression. LCA demonstrated rHDPE-based significantly lower environmental virgin HDPE. Using rHDPE critical reducing footprint composites, incorporating further decreases GWP emissions enhancing certain properties.
