The solution reduces environmental waste, lowers raw material costs, and supports local bioresource utilisation while producing biodegradable materials aligned with global sustainability goals.

‍

Plastic pollution continues to pose severe environmental threats due to the persistence of conventional plastics in landfills and marine ecosystems. At the same time, agricultural and food processing waste such as sago residue and eggshells are often discarded without value recovery.

‍

The project converts sago starch into a biodegradable polymer matrix and reinforces it with calcium carbonate derived from eggshell waste. This reinforcement improves structural integrity, making the material more suitable for packaging and disposable product applications.

‍

The technology uniquely integrates two waste streams into a single value-added material, improving performance limitations commonly associated with starch-based bioplastics.
