- Carbonxt Group Limited (ASX:CG1) is an Australian cleantech company that develops, manufactures, and markets specialized activated carbon products, including powdered activated carbon and activated carbon pellets, for the removal of pollutants and toxins such as mercury, sulfur, volatile organic compounds, phosphates, and hydrogen sulfide in industrial processes; these products serve air purification, wastewater treatment, and potable water production applications for coal-fired power plants, cement plants, waste-to-energy facilities, industrial boilers, incinerators, and other liquid and gas phase markets. The company operates primarily in Australia and the United States, where it generates the majority of its revenue, with manufacturing facilities including sites in Minnesota, Georgia, and a joint venture plant in Kentucky. Founded in 2001 and headquartered in Sydney, Australia, Carbonxt focuses on non-brominated, non-corrosive activated carbons that maintain efficiency without deterioration.
In recent developments, Carbonxt secured a four-year, $24 million contract extension in July 2024 with Reworld, a leading US sustainable waste solutions provider, for powdered activated carbon supply commencing October 2024, expected to increase annualized group revenue by over 25%; the company also renegotiated multiple powdered carbon contracts to raise pricing, with benefits accruing in fiscal 2025. Additionally, Carbonxt raised AU$1.5 million in October 2025 and AU$3.02 million in September 2024 to advance its ownership in NewCarbon Processing, LLC, a joint venture with Kentucky Carbon Processing LLC, increasing its stake from 35.5% with options to reach 50% through further USD$4.5 million investment, to commission a new activated carbon plant in Inez, Kentucky, targeting expansion to 20,000 tonnes per annum. These initiatives underscore strategic expansions in US production capacity and emissions compliance solutions amid sustained revenue growth to A$16.2 million in fiscal 2024.
