Corn Could Be The Next Material To Transform PPE Gear Into Eco-Conscious Wear

When you think of corn, the first images might be of a great maize field, buttered popcorn and a movie, or even something you might find on a dinner plate. You probably wouldn’t think of personal protective equipment (PPE). However, that’s precisely what scientists at McMaster University believe corn could eventually be used for.
 
The university has discovered a new way to transform corn into a biodegradable filtration material that could reimagine how medical gear is made. A unique protein in the vegetable called zein was found to have just the right properties to filter out unwanted chemicals. Zein is located in the kernels of maize and is a biodegradable nutrient already used in food packaging and pharmaceuticals. 
 
As the research took place, the scientists realized that not only was zein able to stand in place of traditional filtration fabrics, but it also offered a clean and green solution to medical waste.
 
Of course, the pandemic spurred the hunt for such an alternative. At the height of COVID-19’s reach, almost everyone had a stash of disposable masks in their homes that they needed to use before venturing out. Many still wear a mask when going out or traveling overseas to protect themselves from the spread of the virus.
 
While the primary purpose of the mask to keep people safe from falling ill, it has done little to protect the environment from damage.
 
Corn could be an answer to such a dilemma. Not only can it break down naturally once disposed of, but it is also cheaper. The researchers hope to work with manufacturers to bring the new material to the masses.

The original study was first published in the journal, Membranes.
