The incessant development of new electronic devices and the persistent emission of electromagnetic signals lead to seek new electromagnetic interference (EMI) shielding materials. Due to the increasing global concern about climate change, it seems necessary direct the research on sustainable feedstocks. For the upon reasons, two different types of feedstocks have been chosen. First is lignocellulosic biomass, which is a renewable source. Three different types were investigated: kraft lignin, pine wood and hemp. Second is Red Mud, the major by-product of aluminum production process with big disposable problem. It is mainly composed of iron oxide and other metal oxides. The aim is to create an EMI shielding material where its bulk is made of Red Mud, cover by a conductive layer of graphitize carbon from biomass.
