Segment Analysis of Granular Activated Carbon Market: Products, Applications, and End-Users

Global Granular Activated Carbon (GAC) market size was valued at USD 2.13 billion in 2024 and is projected to grow from USD 2.34 billion in 2025 to USD 3.98 billion by 2032, exhibiting a CAGR of 7.1% during the forecast period.

Granular Activated Carbon (GAC) is a highly porous adsorbent material produced through thermal activation of carbon-rich precursors such as coal, coconut shells, and wood. With exceptional surface area and adsorption capabilities ranging between 500-1500 m²/g, GAC effectively removes contaminants through physical adsorption and chemical reactions. The material’s versatility makes it indispensable for water purification, air filtration, and industrial processes where contaminant removal is critical.

The GAC market is experiencing renewed growth driven by tightening environmental regulations worldwide, particularly for PFAS removal in water treatment. Industry leaders are responding with sustainable production innovations and reactivation services that improve lifecycle economics. The market’s maturity in traditional applications is being offset by emerging uses in energy storage and advanced air filtration systems.
