Description Seaweed farming gains significance as a climate resilient strategy owing to significant carbon sequestration potential
and research advances to valorize products from seaweed resources. Conversion of seaweeds to biochar enhances
further carbon sequestration. In this study Sargassum wightii, belonging to brown algae has been converted into
biochar under different conditions of pyrolysis for possible application in aquaculture sector. The prepared biochar
was subjected to elemental (CHNS) analysis to assess the nutrient profile. Further, comparative analysis has been
done on raw seaweed and biochar based on the structural characterization using SEM, XRD and FTIR spectra.
Functional group changes were evidenced from FTIR and XRD spectra, whereas surface modifications were
elucidated by SEM analysis. The optimum temperature for biochar pyrolysis of S. wightii to yield higher carbon
content has been identified. A significant observation is that seaweeds in Indian coastal waters are capable of higher
carbon sequestration than in other waters.
