Ecodefend was started by a registered nurse from Hobart. . .

Kaitlyn Cooke Director of Eco Defend Compostable Face Masks

Just one hour of a shift on a children’s COVID ward, using 10 single-use masks, 10 single-use gowns, 10 single-use pairs of gloves, an idea was born.

During a nursing shift in 2020, Kaitlyn Cooke, was taking care of a tiny baby. He was in distress and wanted constant comfort and because it was during COVID parents weren’t allowed on the wards.

Every time Kaitlyn went in to tend to him meant a fresh set of infection-preventing PPE, all heading to landfill after their short use. She couldn’t believe how much waste one tiny patient used.

Yes, covid created unusual times, but honestly, were we that much greener before? Why isn’t environmentally friendlier equipment the norm in our industry yet?

Because no one had created any yet… So, Kaitlyn created one herself!

Kaitlyn is the founder of an all-things product design “Ecodefend”.  Having worked as a healthcare professional, she studied the technical detail of what the masks require and how to make them more comfortable for the wearer.  Kaitlyn has a real passion for a healthier environment and loves working with materials, dealing with manufacturers and waste companies to find the best possible way to manufacture and dispose of our products.
