Young innovator transforms shellfish waste into water purification solution
A seventh-grade student from Texas has developed an environmentally sustainable method to clean contaminated water by converting discarded shellfish shells into a powerful purifying agent. The project demonstrates how agricultural waste can be repurposed to address water quality challenges.

Nathan Gael Montelongo, a seventh-grader from La Joya, Texas, has created a water treatment innovation using chitosan, a natural compound derived from shellfish shells. Recognising the environmental potential of what is typically discarded waste, Montelongo collected shells and processed them into chitosan powder for use in water purification applications.
In laboratory testing, the young innovator demonstrated that chitosan significantly improved water clarity and could remove contaminants from polluted water samples. Experimental trials using zebrafish embryos further validated the effectiveness and safety of the treatment method, suggesting minimal toxicity to aquatic life.
Building on these findings, Montelongo designed a prototype automated raft system capable of monitoring water quality in real-time while simultaneously treating contaminated water. The design represents a practical approach to deploying the chitosan treatment technology in affected water bodies.
The project highlights an emerging opportunity for sustainable solutions to water pollution through waste valorisation. As regions across South and Southeast Asia grapple with freshwater contamination, innovations that utilise abundant agricultural byproducts offer a scalable alternative to conventional chemical-based treatment methods.
