Plastics aren’t going away. But what they leave behind matters.
Most plastics don’t disappear—they break down into microplastics now found in water, the environment, and the human body. For products used in and on the body, this is becoming impossible to ignore.
Why PHA—and why Phast
Most “sustainable” plastics either still leave microplastics behind or require industrial processing to break down.
Phast is different.
Produced through natural fermentation, PHA materials are bio-based, biodegradable, and designed to break down without leaving microplastics.
But material alone isn’t enough. Phast makes PHA work in the real world.
What sets Phast apart
True microplastic-free end of life
Breaks down naturally, including in home compost environments
Engineered for your application
Tuned to meet real product performance requirements
Works with your existing process
No changes to thermoforming, molding, or extrusion
Built for real-world adoption
Comparable performance with minimal cost impact in high-value applications
Traditional Plastics
❌ Fossil fuel-based
❌ Persist for decades or centuries
❌ Break into microplastics
Phast PHA Materials
✅ Bio-based and biodegradable
✅ Break down naturally
✅ Leave no microplastics behind
Built for high-value, high-impact applications
Dental
Every dental product sits directly in the patient’s mouth, often for hours a day, over weeks or months. From aligners to whitening trays, traditional plastics can introduce microplastic exposure through daily use. Phast enables dental companies to replace those materials without changing how products are made.
