NC A&T State University Coal Ash Composite

Using a polymer to encapsulate the coal ash, this simple technology prevents the leaching of heavy metals into the groundwater and the air. The material can be molded into a wide variety of shapes and density, which creates a wide range of applications. This process does not require the returning of the ash to create the ideal carbon content. Any dry ash will work. This prevents further emissions into the environment, while conserving water and energy.  

First Major Coal Ash Composite Installation Complete

Dhruva Shivakumar created an Eagle Scout Project for Brooks Global Studies Elementary School in Greensboro, NC. He shared his experience of working with his dad on this project in this extended interview. See local news coverage below.
