Thermal decomposition processes of a reconstituted cast-leaf tobacco: fate of nitrogen and carbon

Key Points

• Thermal decomposition increases nitrogen and carbon retention in biochar, enhancing its soil amendment potential.
• During combustion, around 70% of nitrogen is released in gaseous form while carbon is primarily retained.
• Analysis of thermal behavior focused on various temperatures and conditions, assessing effects on nitrogen and carbon pathways.
• Findings highlight the significance of optimizing thermal processes for effective resource recovery from tobacco biomass.
