Following my initial exploration into biomaterials in Semester One, I decided to continue experimenting with eggshell waste and biomaterial development. I transitioned from bioplastic experiments with eggshells to focusing on eggshell bio-ceramics. This shift was driven by a desire to create a more multifunctional and sustainable material that benefits both chickens and the environment. Eggshells, abundant in calcium and commonly used as feed for chickens, paired with sodium alginate, a beneficial additive for poultry health, formed the basis of my new biomaterial exploration. This combination serves a dual purpose within a circular system: broken prototypes can be fed to chickens as nutrient-rich feed, while dissolved materials can enrich soil as a natural fertiliser, fostering plant growth. Despite initial plans to feed prototypes to chickens, challenges like mould growth on the ceramics and current restrictions due to Avian flu advice meant that I had to use the material for compost instead.
