Abstract

. Scanning electron microscopy (SEM), atomic force microscopy (AFM), and particle size analysis further confirmed the irregular but consistent particle morphology and surface roughness conducive for polymer reinforcement. The findings establish walnut shell-derived microcrystalline cellulose (MCC) as a promising bio-filler with favourable properties for green composite applications. These applications offer a sustainable alternative to wood-based cellulose, contributing to the circular bioeconomy in walnut-producing regions. This aligns with Sustainable Development Goal (SDG) 12 on responsible consumption and production.
