Environmental Materials (EMI) supports the beneficial recycling of industrial by-products such as coal fly ash, lime kiln dust (LKD), syn gyp and cement kiln dust (CKD).  EMI specializes in the marketing, sales, bulk storage and handling (hauling/transfer, unloading) of these materials.

Key EMI Facts

• EMI mainly supplies its coal fly ash product, Enviro-Dry, to the Bakken oil fields in North Dakota to stabilize oil field waste during the land reclamation process.
• Other beneficial recycling uses include: use as a substitute material for portland cement to make concrete stronger, mixing with native soils for road stabilization, mine reclamation, and more.     
• At EMI's ash bagging facility, a 1 ton Enviro-Dry super sack bag can be filled in as fast as 35 seconds.  Up to 560 bags can be filled in 1 day! 
• Our ash blending system involves 2 silos that can mix fly ash based on customer specified requirements.  Customers can buy bagged or bulk fly ash.

Citizens for Recycling First is an organization that allows individuals to unite in:

• Supporting coal ash recycling as a safe and environmentally preferable alternative to disposal
• Telling the truth about regulations under development and their potential impact on recycling
• Assertively challenging misleading news media characterizations of coal ash
• Find out more at http://www.recyclingfirst.org .

There are many good reasons to view coal ash as a resource.  Recycling it conserves natural resources and saves energy.  In some cases, products made with coal ash perform better than products made without it.  For instance, coal ash makes concrete stronger and more durable.  It also reduces the need to manufacture cement, resulting in significant reductions in greenhouse gas emissions.  Other beneficial recycling uses include:  mixing coal ash with native soils for road stabilization and other in-ground structural fill uses such as a reclamation product in oil fields and numerous other applications where it has an economic value.     
                                           
Almost half of America’s electricity is generated by burning coal. That figure is not likely to change much in the future. Because Americans continue to consume more electricity every year, renewable energy sources will do well just to keep up with increases in demand. The U.S. Department of Energy predicts that in 2030, we will actually generate 19 percent more electricity from coal than we did in 2007.

Generating that much electricity produces large volumes of coal ash — solid materials left over from the combustion process. According to the American Coal Ash Association, about 136 million tons of this material was produced in 2008. The good news is that over 44 percent of it was recycled rather than disposed.

Coal ash comes in many forms, the main two being fly ash and bottom ash.  Fly ash (about 75%of coal waste) is an extremely fine powder that can be recycled for numerous beneficial uses or disposed of in either dry storage such as landfills or wet storage such as ponds or impoundments.   Bottom ash (about 25%) is the heavy particles left in the boiler after the coal is burned.
