Observational analysis highlights extraction of chitin and chitosan from Irish brown crab waste, indicating potential for sustainability.

Extraction yielded 17.60% chitin and 50.45% chitosan from crab shell waste, demonstrating efficient valorization.
FTIR analysis confirmed structural transitions in chitin to chitosan, showing distinct spectral shifts through processing steps.
DSC findings revealed increased thermal stability with enthalpy rising from 72.58 J/g to 253.28 J/g in the final chitosan product.
Overall, methods utilized promote a circular economy by converting waste into valuable materials for end-product applications.

Sufian et al. (2025) studied this question.
