The materials used in electrical and electronic applications have great importance and broader applications, but they have severe electromagnetic interference (EMI). These materials have extensive applications in broadcasting, medical industries, research, defence sectors, communication and similar fields. The EMI can be addressed by using effective EMI shielding materials. This review presents a detailed, comprehensive description for making electromagnetic interference shielding material by recycling various wastes. It starts with highlighting the overview of electromagnetic interference shielding (EMI) and its theoretical aspects. It provides a comprehensive and detailed understanding of recent trends in the novel approaches towards fabricating EMI shielding from industrial waste, agricultural waste and other miscellaneous wastes. This paper critically reviews the works related to the recycling of wastes like red mud (waste from the aluminium refining industry), ground tyre rubber, tea waste (biowaste) from tea industries, bagasse (waste from sugar cane industry), peanut and hazelnut shells (agricultural waste), waste tissue paper and polyethylene and other miscellaneous wastes like hydrocarbon carbon black and ash for the fabrication of highly effective electromagnetic (EM) interference shielding materials. Highly effective results have been reported using red mud showing maximum efficiency of 51.4 dB in X-band range, various agricultural waste displaying reflection loss of up to - 87.117 dB (in the range 0.01 to 20 GHz) and miscellaneous waste giving EMI SE of 80 dB in X-band frequency. A separate section is dedicated to emphasizing future work and recommendations.
用于电子和电气应用的材料非常重要，应用广泛，但它们具有严重的电磁干扰（EMI）。这些材料在广播、医疗行业、研究、国防部门、通信等领域有着广泛的应用。可以使用有效的 EMI 屏蔽材料来解决 EMI 问题。本综述通过回收各种废物来制造电磁干扰屏蔽材料进行了详细、全面的描述。它首先强调了电磁干扰屏蔽（EMI）及其理论方面的概述。它全面详细地了解了利用工业废物、农业废物和其他杂废物制造 EMI 屏蔽的最新趋势。本文对与废物回收相关的工作进行了批判性的回顾，如红泥（铝精炼工业废物）、废轮胎橡胶、茶叶废料（茶产业生物废料）、甘蔗渣（糖业废物）、花生和榛子壳（农业废物）、废纸和聚乙烯以及其他杂废物，如碳氢黑和灰烬，用于制造高效电磁（EM）干扰屏蔽材料。使用红泥报告了非常有效的结果，在 X 波段范围内显示出最大效率为 51.4 dB，各种农业废物显示出高达-87.117 dB 的反射损耗（在 0.01 至 20 GHz 范围内），杂废物在 X 波段频率下的 EMI SE 为 80 dB。专门有一节强调未来的工作和建议。
