Fly ash is a fine powdery substance that scatters or flies from coal combustion chambers, mostly in thermal power plants.
Emission control devices collect this flying ash, some of which include scrubbers, cartridge dust collectors, electrostatic precipitators, or fabric filters. The disposal of fly ash has been a major ecological challenge, and it is considered a low-value material used mainly for landfilling.
The scenario changed when it was discovered that fly ash could be used as a pozzolanic additive in cement. Today, more than half of the concrete produced in the US uses fly ash in some quantity as a substitute for cement.
The value of the international fly ash market was nearly $12.50 billion in 2021. It is projected to reach approximately $20 billion by 2030, with a 6.1% compound annual growth rate (CAGR).
Factors Behind the Growth of the Fly Ash Market
Several factors aid the growth of the international fly ash market. Some of the major ones include:
Increased Use of Fly Ash in the Construction Industry
Cement production consumes a lot of energy and emits large volumes of greenhouse gases. When fly ash is used to produce Portland cement for manufacturing bricks and is used as a substitute for cement in concrete, environmental and economic benefits follow along with the increased use of fly ash in the construction industry.
Fly Ash Benefits Agricultural Purposes
In countries, particularly Latin American countries, where the agricultural industry is witnessing a rapid rise, a higher rate of crop rotation leads to soil erosion and degradation.
In such a scenario, fly ash becomes very useful for soil restoration, stabilization, and wastewater management. It also helps to make the soil smoother, more fertile, and has a higher water content, making it more suitable for agriculture.
Increased Support From the Governments
The Asia-Pacific region dominates the international fly ash market, followed by North America and Europe. The dominance of the Asia-Pacific region is largely due to the rising investments in construction and infrastructure activities in countries such as China, Japan, and India.
These countries are also major fly ash producers because they have many coal-powered thermal power plants. The ecological and economic benefits of fly ash let governments worldwide, particularly in the Asia-Pacific region, bring in regulations and initiatives to promote the use of fly ash in construction projects.
