Project Turn the Tides
Project Turn the Tides showcases HydroPETase, an engineered enzyme to degrade ocean plastic, alongside global education and real-world environmental impact.
THE PROBLEM
The Ocean Plastic Crisis
Every year, over 8 million tons of plastic enter the world’s oceans. Among the most persistent is PET (polyethylene terephthalate), a material used in everyday products like water bottles that can take centuries to degrade. As plastics break down, they form microplastics, contaminating marine ecosystems and entering the human food chain. Coastal communities and vulnerable populations are already experiencing the environmental and health consequences of this crisis.
THE SOLUTION
What is HydroPETase?
HydroPETase is a next-generation engineered enzyme designed to efficiently degrade PET plastic under real-world aquatic conditions, including saltwater environments.
Unlike traditional plastic degradation approaches that require industrial facilities, HydroPETase is being developed with the goal of functioning directly in natural environments such as oceans and estuaries.
Key Innovations:
-
🌊 Engineered for marine-like conditions (salt, pH, temperature)
-
🧬 Combines laboratory mutagenesis with AI-driven modeling
-
⚡ Demonstrates 3–5× improved degradation activity
-
🧪 Tested across multiple environmental conditions
HOW IT WORKS
The Science Behind HydroPETase
HydroPETase builds upon naturally occurring plastic-degrading enzymes by enhancing their efficiency and environmental stability.
-
The enzyme binds to PET plastic surfaces
-
It catalyzes hydrolysis, breaking long polymer chains into smaller molecules
-
These molecules can then be further processed or naturally assimilated
To optimize performance, advanced computational tools were used:
AutoDock Vina → predicted binding affinity
FireProt & FoldX → assessed structural stability
Molecular Dynamics Simulations → tested behavior in saltwater conditions

WHY THIS MATTERS
A New Approach to a Global Crisis
Most current plastic solutions are limited by cost, scale, or accessibility. HydroPETase represents a shift toward biological, scalable, and environmentally adaptable solutions.
This project demonstrates how scientific innovation—when combined with education and outreach—can contribute to addressing one of the most pressing environmental challenges of our time.
HydroPETase is part of a broader effort to bridge the gap between scientific discovery and real-world environmental change.
