BIOCHAR FABRICATED FROM PLASTIC WASTE AND RICE-HUSK FOR CARBON SEQUESTRATION

Abstract

In this work, biochar samples were fabricated from plastics waste (PE and PP) and ricehusk. Raw materials including plastics waste and rice-husk were crushed, and then pressed into pellets according to 100% rice-husk (T), 100% plastic (N) and 70% plastic + 30% rice husk (NT). These pellets were conducted by pyrolysis at conditions of inert gas environment (N2) and temperatures of 350°C and 450°C to obtain the biochar samples. Structural morphologies and characteristics of functional groups of these biochar samples were analyzed by scanning electron microscopy (SEM) and FTIR spectroscopy, respectively. The biochar samples were determined with proximate analysis of volatile organic content (%VOC), fixed carbon content (%FC) and ash content (%Ash). Ultimate analysis of (C, H, N, S, O) elements and yields of the fabricated biochar samples were also examined for carbon sequestration potential
