Waste management, EM pollution, EMI Shielding, Biodegradable, Recycling, Sustainable material


Environmental pollution, one of the critical challenges, is associated with the rapid advancement of various technologies. The huge heap of waste generated as a part of the technological revolution is a main source of environmental pollution, and it is an obstacle which retards the progress of industries. Among the various types of environmental pollution, Electromagnetic interference (EMI) is also a major form which is caused by the telecommunication and electronic industry. EMI can damage the functioning of electronic devices, and it is a severe threat to our health.  Techniques to solve both these pollutions simultaneously are an emerging field of research. Recent studies introduce an efficient strategy to use recycled materials for developing EMI shielding materials. This approach can be equally beneficial for suppressing undesired EM radiations as well as controlling environmental pollution through the recycling of waste materials. This review discusses the recent developments in the strategy of designing biodegradable EMI shielding materials by the use of environmental friendly and biomass-based sustainable materials.
