                         Flaky graphite (GR) and Nickel-Zinc ferrite (FeNiZn) composites in 
                         polystyrene (PS) matrix were studied in the X-Band range (8.2 12.4 
                         GHz). In this work the Expanded Polystyrene (EPS) waste material 
                         was processed into polystyrene through the recycling of EPS. The 
                         polystyrene obtained was utilized as dielectric matrix, mainly 
                         because PS is a wellknown organic polymer that presents low 
                         dielectric loss and light weight, which contribute to applications 
                         in composites for the aerospace field. In order to produce the 
                         final composite specimens, the CGX additive was previously 
                         synthesized through a sustainable method that employed the use of 
                         waste from the paper and pulp industry (black liquor). Afterwards, 
                         the morphological and structural analysis were made through 
                         Scanning Electron Microscope (SEM) and Raman Spectrometer, 
                         respectively. On the other hand, the magnetic ferrite material, 
                         FeNiZn, was obtained for the composite production through 
                         calcination, whereas the GR utilized was commercially obtained. It 
                         was observed that the increase of CGX and GR influenced on the 
                         increase of the Complex Permittivity, and that 10 wt% CGX + 50wt% 
                         FeNiZn composite sample demonstrated an absorption peak at 10.5 
                         GHz. The results are relevant concerning the recycling of EPS 
                         waste through its use as dielectric matrix, thus developing 
                         greener and low-weight composite materials to be used in microwave 
                         applications.",
