STEM the lens URGENT– Calling all people who wear contact lenses. Contact lenses are not bio-degradable. DISPOSE OF USED CONTACT LENSES IN THE SOLID WASTE, DO NOT WASH DOWN THE SINK OR FLUSH DOWN THE TOILET.

Fungus eats plastic
In a rubbish tip in Pakistan, an amazing discovery was made. The fungus Aspergillus tubingensis was degrading the plastic, polyurethane. The mycelium of the fungus spread into the polyurethane and it broke down in a few weeks rather than many years. This was seen using scanning electron microscopy. The technique of Fourier Transform Infrared Spectroscopy was used to confirm the breakage of the chemical bonds. This is a very important observation in the battle against plastic pollution.
