Microplastics
Everywhere, Forever.

They're in our oceans.

They're in our food.

They're in us.

The invisible consequence of synthetic clothing isn't just waste. It's residue.

What Are Microplastics?

Tiny plastic particles — less than 5mm in length. Too small to filter. Too stubborn to disappear. Every time synthetic clothes are washed, they shed microfibres that flow into natural waterways.

Where They End Up

In short: everywhere.

Mariana Trench10,994m deep

Embedded in sediments at the deepest known point on Earth.

Royal Society Open Science, 2019

Arctic Sea IcePolar regions

Acting as a reservoir for global plastic pollution, trapped in frozen layers.

Marine Pollution Bulletin, 2019

SeafoodGlobal oceans

Ingested by fish, molluscs, and plankton — moving up the food chain to your plate.

Environmental Science & Technology, 2015

Human LungsInside us

Found embedded in lung tissue samples from surgical patients.

The Lancet Planetary Health, 2022

BloodstreamsInside us

Detected in human blood for the first time — circulating through our bodies.

Environment International, 2022

PlacentasInside us

Microplastic particles crossing the placental barrier — reaching the unborn.

Environment International, 2021

Breast MilkInside us

Present in human breast milk, passed from mother to child.

Ragusa et al., Polymers, 2022

And increasingly: in us.

Microplastics have been found in human lungs, bloodstreams, placentas, and breast milk.

Invisible to the naked eye

But they're there.

The Synthetic Cycle

What begins as plastic bottles or fossil fuels becomes fabric. That fabric becomes fast fashion. That fashion becomes landfill — or dust. And that dust never really leaves.

↻ The cycle repeats — endlessly

Even recycled polyester, often touted as a sustainable solution, continues to shed plastic particles. There is no such thing as clean plastic clothing.

Natural fibres

Why Natural Matters

Natural fibres biodegrade. They don't linger in the lungs. Or wash into oceans. That doesn't make them perfect. But it makes them less permanent.

Time to biodegrade

Months–years
Cotton
6-12 months
Hemp

Polyester
200+ years
Nylon
30-40 years
Acrylic
200+ years

Out of sight is not out of body

We can't see them.
But they're there.

In the air. In the sea. In our blood. Tiny. Persistent. Unavoidable.

Reducing microplastics starts at the source. And what we wear is part of that.

The solution isn't downstream. It's upstream.
In design. In materials. In choices.

No plastic threads.

No invisible legacy.
