Restraint/Challenge

“Increasing Emission of Fly Ash”

• The increasing emission of fly ash, a key byproduct used as an SCM, presents a significant challenge for the market, as environmental and regulatory concerns about fly ash generation from coal-fired power plants intensify
  • For instance, while companies such as Charah Solutions and Innovative Ash Solutions are developing advanced processing technologies to utilize fly ash more efficiently in concrete production, the gradual phase-out of coal-based energy in several regions is leading to supply constraints, quality variability, and inconsistent availability of fly ash as an SCM
• Regulatory pressures aimed at reducing emissions from coal-fired plants are impacting the supply of fly ash and also raising concerns about the safe disposal and management of this byproduct, which can contain trace amounts of heavy metals and other contaminants
• The need to balance the environmental benefits of using SCMs in concrete with the challenges of sourcing high-quality fly ash is critical for the sustained growth of the market, particularly as the industry shifts toward more sustainable construction practices
• Overcoming this challenge will require greater innovation in alternative SCMs, such as ground granulated blast furnace slag and silica fume, as well as improved fly ash processing and beneficiation techniques to ensure consistent quality and supply
