This study investigates the production of cellulosic bioplastics from four green waste sources: hemp, parsley stem, pineapple leaves, and walnut shell, using either trifluoroacetic acid (TFA) or water as solvents. Synchrotron FTIR Microspectroscopy (SR-*FTIR) was employed to analyze structural modifications during biofilm formation and regeneration.Water-based biofilms retained their native cellulose, hemicellulose, and lignin components. In contrast, TFA-dissolved samples exhibited additional spectral bands in the hemicellulose region, attributed to ester bond hydrolysis and subsequent carboxylic acid formation. Principal component analysis revealed distinct groupings based on solvent type and polymer addition.
