A mushroom found deep in the Amazon can survive on plastic alone.
No oxygen needed.
No landfill too deep.
Meet Pestalotiopsis microspora.
A fungus that quietly rewrote what scientists thought biology could do to synthetic waste.
Students on Yale's Rainforest Expedition programme collected fungi samples in Ecuador.
Back in the lab, they tested each one against synthetic materials.
One strain stood out.
It didn't just tolerate polyurethane plastic.
It ate it.
The findings were published in 2011 — and scientists have been chasing the implications ever since.
Here's the part that stunned researchers:
That last point is the real headline.
Because landfills aren't breezy open fields.
They're compacted, buried, oxygen-starved.
Exactly where conventional decomposition gives up.
Millions of tonnes of polyurethane sit in foams, coatings, insulation, adhesives.
Most of it doesn't degrade for decades.
A fungus that can chew through it without air isn't just a lab curiosity.
It's a blueprint for tackling waste nobody else can reach.
The science hasn't stood still.
No landfill runs on this fungus yet.
But the door it opened in 2011 is still very much ajar.
The Amazon didn't just give us this one fungus.
It gave us a reminder.
Millions of undiscovered microorganisms are sitting in rainforest soil right now.
Each one evolved over millions of years to break down something.
Somewhere out there, the answer to plastic pollution might already be growing on a leaf.
That's all for now!
