Business
Arq, Inc. is an environmental technology company specializing in consumable air, water, and soil treatment solutions with a focus on activated carbon (AC) and chemical technologies. The company manufactures and sells a range of activated carbon products including Granular Activated Carbon (GAC) under brands such as CarbPure GAC and FluxSorb RG; Powdered Activated Carbon (PAC) including CarbPure PAC, PowerPAC, FastPAC, and FluxSorb RP; Colloidal Carbon Products including FluxSorb RC; and various additives like Arq Powder Wetcake as well as emissions reduction additives M-Prove and RESPond. These products are designed to capture and remove contaminants such as mercury, PFAS, and other pollutants for industrial, municipal water and air treatment, coal-fired power generation, and soil remediation markets primarily in North America. Founded in 2014 and headquartered in Greenwood Village, Colorado, Arq operates the only vertically integrated activated carbon supply chain in North America, producing domestically sourced activated carbon products which support environmental regulations and sustainability initiatives. The company completed a significant acquisition in February 2023 of 100% equity interests, assets, and liabilities of Arq Limited subsidiaries, expanding access to bituminous coal feedstock and manufacturing capability in Corbin, Kentucky, to develop advanced GAC products for broader market applications. In 2024 and 2025, Arq has undergone major strategic and operational developments, including rebranding from Advanced Emissions Solutions to Arq, securing a $30 million asset-backed lending facility to enhance financial flexibility, and completing construction of its Red River GAC facility. The company achieved first GAC production by early 2025 and is ramping up to a full nameplate capacity of 25 million pounds of GAC annually, with approximately 16 million pounds already contracted and ongoing negotiations for remaining capacity. Arq reported a 10% revenue increase to $109 million in fiscal year 2024 with a 36.2% gross margin, showing significant operational improvements and positive adjusted EBITDA growth. These efforts position Arq to capitalize on a growing market demand for granular activated carbon and to complement its established PAC business as a foundation for future expansion and profitability. Arq’s sustained innovation is supported by over 140 granted patents and patent applications in activated carbon and related technologies, and its operations include energy efficiency leadership with surplus electricity generation at its Red River facility. The company strategically focuses on enabling cleaner, safer environments through sustainable value creation and is advancing transparency and sustainability in its reporting and operational goals. This profile reflects Arq’s comprehensive product portfolio, recent financial and operational milestones, strategic acquisitions, and its role as a growth-focused leader in activated carbon solutions in North America.
