Engineers from the Colorado School of Mines have found a new way to get minerals. Rather than dig them out of the ground, the researchers are finding resources in the trash. So far, the project has been able to turn left-over banana peels, eggshells, and rice husks into crystal-clear glass. The process grinds the garbage into fine particles, and then dries then out producing a fine white powder. The powder is then put into an oven which melts it at 3,000 degrees. The molten red substance that comes out of the oven is poured into molds to make glass. Materials engineer Ivan Cornejo, who leads the project, said they are trying to calculate how much waste they could divert from landfills and turn into useful products. He says the material they produce can be used to meet the world’s growing demand for silica, rather than mining it. When asked about the project, Cornejo said, “There’s no reason to continue mining, destroying the environment, when we can find many of the materials we need from waste.”—Jim L.
