What is it about?
Textile dyes pollute water and harm the environment. We made eco-friendly films using two waste materials: whey protein from cheese-making and coral waste, mixed with a biodegradable plastic. These films removed up to 94% of two different dyes and worked well on real factory wastewater. They can be reused, offering a cheap, green way to clean polluted water.

Why is it important?
This study uniquely turns two waste streams whey protein and coral waste into a single biodegradable film for dye cleanup. The novelty lies in using natural coral-derived hydroxyapatite within a PVA/WP matrix, with PW-H2 achieving the best structural–adsorption balance. It removes both cationic and anionic dyes, shows strong selectivity (S = 1.95) for cationic BCB, and is validated on real textile effluent, proving real-world scalability.
Perspectives
This research turns two waste problems into one solution cheese byproducts and coral waste become a water-cleaning film. That circular thinking excites us. The real textile effluent validation gives us confidence this isn't just lab theory. We do wonder about long-term reusability and cost at scale, but overall, this feels like practical, affordable sustainability that factories could actually adopt.
