Fungi That Can Break Down Plastic - How Does That Work?

Scientists have found certain fungi that can break down types of plastic, including materials that usually take years to decompose.

How it works:
Some fungi release enzymes (special proteins) that can break long plastic molecules into smaller pieces. This is similar to how fungi break down wood in nature.

Why this matters:
Plastic waste is a major environmental problem. If fungi can help break it down safely, they could be used in waste management or recycling systems.

What scientists are still studying:

  • How fast this process can happen
  • Whether it works on large amounts of plastic
  • If it’s safe to use at scale

Think about it:
Where would fungi-based plastic breakdown be most useful?

So could this actually solve plastic pollution or just small amounts? What percentage of the mass can the fungi degrade?

I read about this and tried testing something related. Testing Whether Fungi Can Grow on and Break Down Plastic

I used a small piece of plastic and exposed it to a damp environment where I had some fungal growth (not sure what species).

After about a week, I didn’t see the plastic break down, but I did notice growth forming on the surface.

Does the fungus actually break the plastic down directly, or is it a much slower process than that?
