Crab shell extract has been converted into a bioplastic by scientists from the Anteneo de Manila University to make optical parts known as diffraction gratings. Lasers, wavelength division multiplexing, & spectrometers use diffraction gratings (DG) to split light into its component colors in different directions. Silicone can be replaced by crab shell extract in DG to create lightweight, biodegradable, & affordable gratings. A competitor to lithium-ion called “crab carbon” can be made by upcycling crab shell waste. Crab shell waste or chitosan can be used as nanoparticles to treat lung cancer. Chitosan could be used to reduce waste, improve sustainability, … Continue reading Scientists Turn Waste Crab Shells into Wonder Bioplastics For Breakthrough Optical Technology
