Abstract

This thesis investigates whole-cell algae as a possible binder matrix for fully bio-based composites and evaluates agricultural residues as reinforcing fillers. The study quantifies how feedstock morphology and preprocessing govern microstructure and mechanical response under compression molding that uses only water, heat, and pressure. Candidate algal feedstocks include food grade algae, single strain wastewater algae, and mixed wastewater communities.
