Sustainable Electromagnetic Interference Shielding with Biomass Waste

This chapter explores the sources of electromagnetic interference (EMI), its harmful effects on health and immunity, and its impact on interference and compatibility in power converters. While exploring shielding mechanisms of biomass-derived materials, showing their potential as eco-friendly alternatives to traditional EMI shielding solutions. With growing environmental concerns and increased EMI pollution from electronic devices, the need for eco-friendly, efficient shielding solutions is more pressing than ever. Biomass-derived composites, sourced from agricultural residues, forestry waste, and marine organisms, offer a unique combination of lightweight, biodegradable, and cost-effective properties. This chapter explores how biomass-derived materials naturally shield against electromagnetic interference through reflection, absorption, and multiple scattering, thanks to their unique structures and compositions. By comparing different biomass sources, processing methods, and hybrid composites, it highlights how their electromagnetic properties can be customized for various stealth and EMI shielding needs. This chapter emphasizes how sustainable material design can help tackle electromagnetic pollution while also being sustainable. By combining smart waste management with cutting-edge technology, biomass-derived composites stand out as great options for lightweight, high-performance EMI shielding in fields like aerospace, automotive, and wearable electronics.
