The two largest beneficial uses of encapsulated coal combustion residuals (CCR) — commonly known as coal ash — are in concrete/concrete products/grout and in gypsum panel products. 

High capacity rotary dryers can be used to extract combustible materials from a seawater-and-algae slurry for the production of biofuels.

Dr. Donald Fosnacht, director of the NRRI Center for Research and Technology Development, will present "Manufacture of Moisture Resistant Torrified Biomass Agglomerates" at the International Biomass Conference on March 26. 

Used to heat materials that are fine and dusty, sensitive to oxidation, combustible, explosive, potentially contaminating or thermally sensitive, rotary calciners isolate the materials to be processed in a high-temperature chamber.
