Europe's activated carbon market is projected to grow from $1.06 billion in 2025 and $1.12 billion in 2026 to $1.46 billion by 2031, representing a 5.39% compound annual growth rate from 2026 to 2031. ResearchAndMarkets.com attributes the expansion to stricter water-quality standards, tighter industrial emissions limits and rising use of purification technologies. Municipal utilities are preparing for a binding January 2029 deadline covering the monitoring and removal of per- and polyfluoroalkyl substances, while industrial plants are increasing powdered activated carbon use to meet mercury limits. Powdered activated carbon held 47.65% of 2025 revenue and is forecast to grow at a 5.67% CAGR through 2031. Feedstock volatility, substitute materials and Carbon Border Adjustment Mechanism costs remain constraints.
