Microplastics Explained
Microplastics are tiny plastic particles created when larger plastic items break down over time, which can enter ecosystems and food chains, creating environmental concerns.
What are microplastics?
They are plastic fragments smaller than 5mm, formed through the gradual breakdown of larger plastic products and packaging, which persist in the environment far longer than most people realise.
Where do microplastics come from?
- Degraded single-use plastic packaging
- Synthetic textiles and clothing fibres
- Broken-down plastic void fill and mailers
Why microplastics matter
-
Environmental persistence
They do not fully biodegrade, remaining in ecosystems indefinitely. -
Food chain contamination
Microplastics can be ingested by wildlife and enter the human food chain. -
Driving material change
A key reason businesses are shifting towards paper-based and plastic-free packaging.
