What is EZBase®?
 EZBase® is a byproduct made from circulating fluidized bed (CFB) boilers located at the JEA Northside Generating Station (NGS). These CFB’s are fueled by a combination of coal and petroleum coke. Limestone is added during the power generation process to create thermal mass and to aid in the removal of sulfurous gas emissions. At the conclusion of this generation process, two dry byproducts are generated, fly ash and bed ash. These dry ash byproducts are mixed with water to create a slurry that is further processed into the value-added byproduct, EZBase®.
Byproduct from a solid fuel CFB plant, such as the JEA NGS facility, is distinct from that of conventionally fired boilers (e.g., pulverized coal, fuel oil) because it is composed primarily of lime and gypsum (calcium oxides and calcium sulfate, respectively). Less than 10% by weight of CFB byproduct actually represents what would generally be termed “ash” from combustion of the fossil fuels. Over 90% by weight of CFB byproduct is a result of the addition of the limestone to the boilers. Thus, the byproduct from a CFB plant is not an “ash” in the typical sense, and is not solely the remnant material from conventionally-fired boilers. As noted the EZBase® byproduct is primarily lime and gypsum which gives it excellent cementitious properties that allow it to be used in construction applications where limestone, cement and concrete would otherwise be used.

Is EZBase® Environmentally Friendly?
JEA conducted a two-year beneficial use demonstration (BUD) to determine the potential for environmental or health effects associated with EZBase®. As a result of this effort, EZBase® was deemed non-hazardous as defined by the Environmental Protection Agency (EPA) and the Florida Department of Environmental Protection (FDEP). FDEP has determined that use of the EZBase® constitutes a beneficial use of an industrial byproduct when used in specific applications. During the BUD process, effects of EZBase® on soils, surface waters, and groundwater were evaluated by several different approaches, including field studies. The material was judged to be safe for the approved applications and did not pose a threat to humans or to the environment, including personnel applying the product as a part of their daily tasks. Through this demonstration, EZBase® was determined to be safe for use as a replacement for other conventional civil construction materials such as limestone and concrete.

Is there a Material Safety Data Sheet (MSDS) available for EZBase®?
Yes. You will also find MSDSs for other traditional construction materials. These are strictly to demonstrate the similarities of EZBase® with common materials which would be used if EZBase® were not available. JEA does not produce these materials.

What is EZSorb®?
 EZSorb® is a byproduct made from circulating fluidized bed (CFB) boilers located at the JEA Northside Generating Station (NGS). These CFB’s are fueled by a combination of coal and petroleum coke. Limestone is added during the power generation process to create thermal mass and to aid in the removal of sulfurous gas emissions. At the conclusion of this generation process, two dry byproducts are generated, fly ash and bed ash. These dry ash byproducts are EZSorb®.

What common applications is EZSorb® used for?
Since EZSorb® is a byproduct of electric generation, it comes at a low cost compared to existing alternatives. The following are potential applications for EZSorb®:
- Additive for stabilization of soils and construction fill material
- Solidification and fixation of sludge materials
- Acid waste neutralization
- Soil additive for liming
- Additive to cement and/or other raw construction materials
Is there analytical data on EZSorb® available?
Yes. X-ray fluorescence analysis (XRF), X-Ray defraction analysis (XRD) and TCLP analysis are all available upon request at ezbase@jea.com
