THERMOCHEMICAL RECYCLING OF AGRICULTURAL WASTES TO USEFUL PRODUCTS

Abstract: In this study, the recycling of corn wastes from corn production by pyrolysis method was investigated. Corn wastes after the corn harvest were pyrolyzed in laboratory scale fixed bed pyrolysis system and pyrolysis product analyzes were carried out. FTIR and SEM analyzes were used for characterization of the solid product. FTIR analysis revealed some aromatic functional groups. As a result of SEM images, it was observed that as the pyrolysis temperature increases, the organic waste becomes more granular by decomposition. GC-MS analysis was used to determine the composition of the liquid pyrolysis products. According to GC-MS results, compounds with a high degree of aromaticity were observed in the whole liquid products. As the pyrolysis rate and temperature increased, the compounds in the liquid product were broken down into other compounds. From all the data obtained, corn waste has been found to be used as fuel and as a source of raw materials in different areas because of the high thermal value of liquid pyrolysis products.
