Thermo-gravimetric and kinetic analysis of residues from biological treated food waste
In order to study the thermal behavior of residues from bio-treated food waste composition,and characterization of the residues were investigated.The major components identified were lignin,plastics and bones.Further,investigations of pyrolytic characteristics using thermo-gravimetric analysis were studied on the single and mixed components.The experiments were conducted at a temperature range of 30℃-900℃ at the heating rate of (10℃/mins) in the presence of nitrogen atmosphere with a flow rate of 20mL/min-1.Subsequently,kinetic analysis and mechanism were performed on therrno-gravimetric data of the single and co-pyrolysis components after thermal decomposition.The maximum weight loss temperature for bone and lignin occurred at 335℃,while plastic residues maximum decomposition peak temperature occurred at 476 ℃.Plastic in the mixtures displayed an increased maximum decomposition temperature of 500 ℃ where substantial complete decomposition occurred in the copyrolysis.The combination of the three residues indicated that experimental and calculated TG/DTG curves were in good agreement However the solid parts of the different components of the pyrolytic process of interaction do not follow the behavior of individual feedstock in the mixtures.It showed that low-temperature pyrolysis stage (<350 ℃) signifies no synergy among residues,while synergistic interactions was noticed with no inhibition of lignin and bone char residues at more than 350 ℃ on plastic.This phenomenon resulted in low activation energy requirements and residues mixtures suitability for disposal through pyrolysis process.
