"content": "The Aluminium Sulfate industry trends over the past 18 months reveal a pivot toward circular supply chains and low-carbon chemistries. In March 2024, Kemira Oyj partnered with Norsk Hydro to pilot green-alumina extraction from bauxite residue, trimming process CO₂ by 28 % and securing a 2026 commercial target. Grasim Industries followed in July 2023, acquiring Sree Rayalaseema Alkalies’ 120 ktpa wet-end plant for USD 94 million, doubling its Southern India water-treatment footprint overnight."

In response, G2O Technologies launched a nanofiltration coating in October 2023 that lets paper mills slash alum dosage by 18 % while maintaining brightness, already adopted by Mondi’s Świecie mill."

Meanwhile, municipal buyers are shifting from bulk powder to bulk-delivered 48 % solution, driven by dust-abatement mandates and automated dosing retrofits."
