Sustainable valorization of water hyacinth waste pollutant via pyrolysis for advance microbial fuel investigation

Present study has been focused on the bio-energy potential of waste biomass (water hyacinth leaves and its stem). Pyrolysis of both biomasses were investigated at five different heating rates (5-25 degrees C/min) using thermogravi-metric analyzer. For both biomasses, maximum thermal degradation occurred within the temperature range of 200-400 degrees C, which is the active pyrolytic zone. Three non-iso-conversional (degradation models) including the Kissinger-Akahira-Sunose, Flynn-Wall-Ozawa, and Starink were used to calculate the activation energy of both biomasses. The activation energy was around 92-98 kJ/mol for water hyacinth leaves and 151-153 kJ/mol for water hyacinth stems. The results suggest that these low-cost abundantly available biomasses have a good po-tential for the production of solid bio-fuel.

Automated summary

The present study focused on the bio-energy potential of waste biomass, specifically water hyacinth leaves and stems. The pyrolysis process of both biomasses was investigated at different heating rates using a thermogravimetric analyzer. The results showed that the maximum thermal degradation occurred within the temperature range of 200-400℃, and the activation energy for water hyacinth leaves and stems was calculated to be around 92-98 kJ/mol and 151-153 kJ/mol, respectively. These findings suggest that these low-cost abundantly available biomasses have great potential for the production of solid bio-fuel.
