Coal Ash

RPM Solutions uses proprietary equipment technology and refined operating skills to provide an innovative approach to coal yard reclamation and ash pond management. Our innovative ASH Solutions reduce cost, reduce manpower, reduce the carbon footprint and expedite the project. Therefore, we are more efficient, cheaper, safer and more environmentally friendly than any competitor.

Coal ash is the largest type of waste generated in the United States, with over 100 million tons produced in the USA every year. Coal ash contains a toxic stew of chemicals including lead, arsenic, mercury and radioactive uranium.

Coal ash, also referred to as coal combustion residuals (CCRs), is produced primarily from the burning of coal in coal-fired plants. Coach ash includes a number of by-products produced from burning coal, including:

• Fly Ash | a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler.
• Bottom Ash | a coarse, angular ash particle that is too large to be carried up into smoke stacks, so it forms in the bottom of the coal furnace.
• Boiler Slag | molten bottom ash from slag tap and cyclone type furnaces that turns into pellets that have a smooth glossy appearance after it is cooled with water.
• Flue Gas Desulfurization Material | leftover from the process of reducing sulfur dioxide emissions from a coal-fired boiler that can be a wet sludge consisting of calcium sulfite or calcium sulfate.

Coal ash is disposed of or used in different ways depending on:

• The type of by-product
• The processes at the plant
• The regulations the power plant has to follow

Coal ash contains contaminants like mercury, cadmium and arsenic. Without proper management, these contaminants can pollute waterways, ground water, drinking water and the air. Our operators at RPM Solutions bring a deep wealth of mining and machining experience. We differentiate ourselves through our advanced skills and preparation. Our commitment to detail is the most important component of our success.

Reusing coal ash can create many environmental, economic and product benefits. Coal fly ash has been successfully used in portland cement concrete as a mineral admixture and more recently as a component of blended cement. For every ton of fly ash used in place of portland cement about a ton of carbon dioxide is prevented from entering the earth’s atmosphere. Also, it takes the equivalent of 55 gallons of oil to produce a single ton of cement. Another significant benefit of using coal fly ash is that it requires less water than portland concrete cement, conserving a limited resource, while also reducing a project’s water and equipment costs. Fly ash concrete has increased strength and durability, which means it can handle greater loads, is more resilient and lasts longer. Fly ash concrete can withstand harsher service environments than straight portland cement concrete. It is less susceptible to chemical attacks and mitigates the negative impact of deleterious aggregates.
