Ash Resources Reveals Its Process Behind Extracting Fly Ash from Thermal Power Stations

Online, August 12, 2010 (Newswire.com) - Norwich, UK- Ash Resources' Strategy and Marketing Manager, John Sheath, told Energy Digital about the process behind extracting fly ash from thermal power stations. Essentially a waste product, the company has found a way of removing it from the flue gases given off by burning coal.

Today, the business operates a sustainable model, taking a product that would otherwise be dumped, and processing it for use in the construction industry mainly.

In fact, Ash Resources can do three things with the fly ash it collects from power stations: sell it dry without any processing, add water to transport it, or pass it through a classifier.
The classifier means the fly ash can be sold on as a value-added product for use in concrete and cement.

Sheath explained to Energy Digital that fly ash that is not extracted and re-used is simply dumped. Fly ash is commonly used as a cement extender which helps reduce the costs for companies that produce the cement, and also decreases the amount of CO2 emitted during production.

The same material used in a concrete mix has greater benefits for the product itself, Sheath adds, resulting in a much denser concrete, which is ultimately stronger and resistant to water, chemicals and sulphates.

In the short-term, Ash Resources will concentrate on utilising the capacity it already has, having opened a site at Matimba power station recently. That means finding other ways in which to use this waste material.
