Sustainable Plastics & Bioplastics
PLA, PHA, and starch-based biopolymers — synthesis, processing, compostability standards, and the commercial reality of drop-in bio-based replacements for conventional packaging and consumer products.
“Bio-based does not automatically mean biodegradable. True sustainability requires rigorous life-cycle analysis from feedstock to soil.”
