EPA OKs Recycled Coal Ash For Concrete And Wallboard

The United States Environmental Protection Agency (EPA) recently approved waste coal ash as an acceptable recycled material to be used in the production of concrete and wallboard for construction purposes. Coal ash is the leftover waste material when coal boilers are used for steam power generation in large-scale industrial settings.

In a recent press release, the EPA stated that it had determined that using CCR’s or coal combustion residuals in construction materials such as wallboard and concrete is an acceptable alternative to the use of virgin materials or to other waste materials that rank less favorably on the EPA’s environmental benchmarks and well-being scale.

The EPA determined that the waste coal ash could be used as a portland cement substitute in concrete as an alternative to mined gypsum in wallboard. As nearly half of all coal ash is currently used in cement and wallboard, the EPA approval will help to boost sustainability and further lessen environmental impacts. Currently, a little more than half of all coal ash produced is placed in landfills – the more opportunities there are for the recycled material to be used productively, the less need there is for ground surface space to dispose of it.

WasteCare Wants You to Remember: Staying aware of the latest EPA developments can help you and your business save money. If your business deals with coal ash residues or concrete and wallboard, this recent approval may help you to reduce your disposal costs or reduce the price of commonly used materials. Paying attention to news from the EPA and your state’s environmental agency can help keep you in the know about grant opportunities, legal changes, and training and development programs that can help your business, employees, and community!
