Denise Stilling, a mechanical engineer at the University of Regina, turns used face masks into materials for anything from countertops to pavement blocks.
"What a great opportunity if we look at our landfills that are filled," she said.
First, she removes the ear loops and metal nose piece. Then, she manually cuts the masks into strips. Those strips go into a shredder, which pumps out a fluffy material.Then, Stilling mixes the fluff with other waste products such as old tires and sand. She also adds olive oil to bind them. "If it's something brittle," she said, holding up a thin tile, "then as you can see, this would make a great clip board. I can make this into rulers."
Graduate student Anaamalaai Annamalai Senthilnathan, 24, manually slices up some of the used face masks.
