💡 Researchers at IBEC have developed a novel biomaterial from chitin, inspired by nature, as a potential plastic replacement.

💧 This new material strengthens when exposed to water, unlike most biomaterials that weaken.

🔬 The biomaterial, a nickel-doped chitosan, showed tensile strengths between 30-40 MPa when dry, increasing to 53.01±1.68 MPa when wet, similar to high-performance plastics. It also demonstrated a biodegradability half-life of approximately four months in soil.

🌍 A zero-waste production cycle has been developed, utilizing expelled nickel and water for subsequent batches, with potential for large-scale production.
