Some construction and demolition materials can easily be resold or recycled after a project is completed. Items like scrap metal, masonry, and wood typically are in high demand and there are many organizations and businesses interested in acquiring them. But what to do with building materials that have less demand like gypsum wallboard?
Currently, research in underway at the University of North Carolina, Charlotte to determine the effectiveness of this material as a soil additive.
While drywall isn’t considered a toxic material, when it is disposed of in a landfill it can produce hydrogen sulfide, a potentially dangerous gas. When the drywall is left for garbage, it’s beneficial components, namely, calcium sulfate, a proven and safe soil amendment, are wasted from being reused.
In preliminary research, gypsum drywall successfully increased the yield of a canola crop when it was used as a soil additive. The study also showed that there is potential for the drywall to increase the amount of carbon captured in the soil and thus reduce the amount released into the atmosphere as green house gas.
Establishing a way to waste recycle drywall would benefit construction firms by saving money on waste disposal fees, reduce the incidence of dangerous gasses developing in landfills, and help to replenish and strengthen crops and other agricultural needs.
