Prawn and crab shells accumulate at seafood processing units. These can be converted into chitosan for water treatment, food packaging films, or wound-healing products. Step-by-step: Collect shells → Deproteinise and demineralise → Extract chitosan → Dry and refine. High-value output from low-value waste supports eco-friendly industries. It adds income layers for coastal communities while addressing pollution. The sharpest opportunities lie in materials others see as disposal problems..
