A series of (Epoxy/Polyurethane)/Apple Waste Activated Carbon (EP/PU)/(AWAC) bio composites have been prepared with varying amounts of apple waste activated carbon (AWAC) viz., 0, 2.5, 5, 7.5 and 10 wt %. The prepared bio composites have been characterized for physico-mechanical behaviors and chemical resistance. The obtained biocomposites have characterized via thermogravimetric analysis (TGA), Differential Scanning Calorimetry (DSC), and Scanning electron microscopy (SEM) to reveal the effect of the presence of the apple waste activated carbon (AWAC) on the properties of the obtained adsorbent. The thermal degradation behaviors of bio composites have been established using TGA thermograms. These results indicate that it is possible with increase the apple waste activated carbon content adsorption of (EP/PU)/(AWAC) is increased. Developed biocomposites from apple waste materials will help to reduce the overall cost of the materials for its demanding applications as insulating material. The as-prepared (EP/PU)/(AWAC) bio-adsorbent removes the cationic dyes from the waste water.

In present work, orange peel derived activated carbon (OPAC) /Fe3O4 loaded into polyurethane biocomposites were synthesized with different weight fractions of (OPAC)/Fe3O4 via, 0.5, 1 and 2 wt% filler in the biocomposites. The physico – mechanical, thermal characteristics and magnetic properties of fabricated (OPAC)/Fe3O4 filled biocomposites have been measured by using DSC, TGA, DMA and VSM. A slight improvement in thermal stability was noticed for (OPAC)/Fe3O4 loaded biocomposites. The PU/(OPAC)/Fe3O4biocomposites are thermally stable up to 250ºC and completely degraded above 520 ºC. The biocomposites degradation kinetic parameters for each step of the thermal degradation processes have been studied using two mathematical models namely, Coats–Redfern and Broido's methods. The PU/(OPAC)Fe3O4 biocomposites showed high mechanical, magnetic, thermal properties at a low loading of 2 wt.%, and could potentially be used for a wide range of applications.
