New studies are looking to use the waste product of coal-fired power plants, gypsum, to combat water pollution from fertilizer runoff. As scientists point out, the calcium in the material binds with phosphate creating a compound that resists runoff, thus decreasing water pollution. What’s the appeal in using waste gypsum? When a byproduct of power plant processes, the mineral is much cheaper and more readily available. A report detailing the solution states that “Researchers saw a possible comeback for the waste product as nutrient pollution problems grew and coal-fired power plants proliferated.” Read more about the idea here.
