Why plastic-free?

With the average person using 0.34 kg of plastic every single day, humanity produces an astonishing 460–500 million metric tons of plastic waste each year. To put that into perspective, that’s the weight of 3,700 to 4,000 Statues of Liberty (with pedestal and base) made entirely of plastic trash—every single year.

Unlike organic matter, plastics don’t break down into harmless byproducts like CO₂ or water. The very properties that make plastics so useful—durability, flexibility, and resistance to degradation—become deeply problematic after disposal. Instead of disappearing, plastics simply fragment into smaller and smaller pieces, becoming what we call microplastics (MPs, <5 mm).

 

Over time, these MPs can be inhaled or ingested by animals and humans, where they may lodge in tissues, trigger inflammation, and cause long-term health risks. Even worse, plastics act like sponges in the environment—absorbing heavy metals and “forever chemicals” like PFAS, which they then transfer to any organism unlucky enough to consume them.

 

With only about 10% of plastics ever recycled, our plastic future looks grim unless we choose a different path. But here’s the paradox: plastics are also woven into the fabric of our daily lives. They keep blood sterile in hospitals, extend the shelf life of food, and provide unparalleled convenience.

 

This love–hate relationship with plastics is at the heart of our mission. At Plastic-Free Pals, we empower students and adults alike to understand the plastic problem and discover how everyday lifestyle changes and collective action can help turn the tide against plastic pollution.

🔬 The Microplastic Detect Kit is now on YouTube!
I’m excited to share the launch of a five part video tutorial series for the Microplastic Detect Kit, designed to bring hands on microplastic research into high school classrooms.

Microplastics can be incredibly difficult to see, but that doesn’t mean students can’t investigate them.

Through this flipped classroom series, educators and students can follow along with the kit to:
💧 Filter water samples and capture particles
🧪 Prepare samples for fluorescence analysis
🔬 Use Nile Red staining to make potential microplastics visible
📸 Examine particles using microscopy and imaging
🧠 Think critically about what the evidence can and cannot tell us

The goal is more than simply teaching students about plastic pollution. It’s about giving students the opportunity to think and work like scientists.

This project grew out of my research on accessible microplastic detection and my experiences working with students through environmental monitoring and science education. I’m especially excited to see these methods move beyond the research laboratory and into classrooms where students can investigate samples from their own communities.

This project was made possible through funding from the Philadelphia Regional Center for Children’s Environmental Health (PRCCEH) via Samantha McBride.

I’d love to hear from educators, researchers, and environmental organizations interested in bringing hands on microplastic science into their classrooms and communities.
