What Makes Up Microplastics?

What Makes Up Microplastics?

Microplastics are everywhere—but their origins may surprise many.

The largest share doesn’t come from visible plastic waste, but from everyday materials and activities:

👕 35% Synthetic Textiles
Washing polyester, nylon, and microfiber clothing releases tiny plastic fibers into waterways.

🚗 28% Tires
Friction from vehicles causes tire wear, shedding microplastics that spread into air, soil, and oceans.

🌆 24% City Dust
Urban sources like shoe soles, artificial turf, and plastic-based materials contribute significantly.

🛣️ 7% Road Markings
Painted road lines gradually break down into microplastic particles.

🔹 6% Other Sources
Including personal care products, marine coatings, and industrial plastic pellets.

🌍 In total, approximately 21 million tonnes of primary microplastics are released globally.

♻️ Why this matters for the Circular Economy

Microplastics reflect a deeper design challenge. These particles represent materials lost from the system—circulating in the environment instead of being recovered and reused.

Key priorities include:
✔️ Designing low-shedding textiles
✔️ Innovating more sustainable tire materials
✔️ Strengthening urban filtration and waste systems
✔️ Transitioning to non-toxic, regenerative materials

A circular economy focuses on designing out waste at the source, not just managing it after creation.
