Getting more from your fly ash waste stream.
Based on an annual survey conducted by the American Coal Ash Association (ACAA) between 1966 and 2011, more than 2.3 billion short tons of fly ash was produced by coal-fire utility boilers. Of that total amount, only about 625 million tons of that fly ash was used in a beneficial manner, mostly for cement and concrete production. The remaining 1.75 billion tons went to landfills or filled ponded impoundments. While use rates for recently generated fly ash have increased considerably in more recent years, approximately 40 million tons is still disposed of annually.
That’s not only a huge loss in terms of the production value of the wasted fly ash, it’s also a terrible burden on the environment. It’s one of the reasons why ST Equipment & Technology came up with a better way to separate dry materials such as fly ash through a proprietary Triboelectrostatic benefication process.
Our environmentally responsible, water-free system doesn’t require the use of chemical or biologicals, so it can liberate particles less than 500 microns in size. The result is a greater, more valuable yield of materials for our clients, as well as a considerably lower amount of waste going to landfills.
It’s one of the reasons why ST Equipment & Technology was chosen as a key supplier in the construction of the New World Trade Center. We produced thousands of tons of high quality fly ash that was used in the creation of superior concrete that is extremely strong and durable.
What can we do for your business? In addition to fly ash, our separation process can be used for a variety of applications with minerals that include Barite, Talc, Calcium Carbonate, Potash, Mineral Sands, Feldspar and more.
