Overview

Experimental analysis reveals accelerated enzymatic and compost biodegradation in poly(butylene adipate-co-terephthalate) composites with reed fiber, indicating viable eco-friendly packaging.

Key Points

To evaluate whether blending reed fiber with poly(butylene adipate-co-terephthalate) enhances the polymer's enzymatic and compost degradation performance.
Subjected poly(butylene adipate-co-terephthalate) (PBAT) and PBAT/reed fiber (PBAT/RF) composite films to a 15-day enzymatic degradation assay across four enzyme solutions: lipase, cellulase, Proteinase K, and esterase.
Evaluated long-term biodegradation during a 3-month (91-day) experiment under controlled composting conditions.
Characterized degradation pathways, structural changes, and morphology using weight-loss measurements, FTIR, SEM, and DSC.
Lipase produced the highest enzymatic degradation rate, resulting in a weight loss of approximately 5.63% for neat PBAT compared to 8.17% for PBAT/RF composites.
Under controlled composting conditions over 91 days, PBAT/RF composites showed a 23.8% reduction in the degradation lag phase and an 11.8% increase in biodegradation rate relative to neat PBAT.
SEM and DSC analyses demonstrated increased surface hydrophilicity, melting temperature, crystallinity, and micro-crack formation in PBAT/RF, facilitating enhanced microbial and enzymatic contact.
