This study uses coir from agricultural waste, electromagnetic shielding carbon fiber, impact-resistant polypropylene (PP), and methylmaleic anhydride-grafted PP (MA-g-PP) to make wood plastic composites (WPCs). According to the experimental results, when coir and carbon fiber are at a ratio of 3:12, the resulting WPC exhibits an maximum electromagnetic shielding effectiveness (EMSE) of -25 dB, which reaches the protective grade of staple merchandise. At fibers ratio of 3:12, the tensile strength is improved by 10% more than at ratio of 15:0; and the increased flexural strength is by 20% accordingly. A multiblending process is used to simulate the recycling and explores its thermodestruction of the resulting WPC. With a ratio of 3:12, the WPC still has an EMSE of -25 dB at nine cycles of multiblending; however, its tensile and flexural strengths both decrease by 10%.
