Carbonxt Group Ltd (ASX:CG1), a US-focused cleantech company, recorded a one-year share price increase of 61.67%, trading at AUD 0.097 per share as of 18 December 2025. The company specialises in engineered activated carbon solutions for industrial and utility partners, supplying both powdered and pelletised carbon products designed to remove pollutants from air and water streams.
Carbonxt is focused on expanding its North American manufacturing footprint, with the Kentucky activated carbon facility positioned as a key growth platform for the company’s future.
Major Developments in 2025
In 2025, the company made significant strides in developing its Kentucky activated carbon facility. An additional USD 750,000 investment was made, increasing its ownership stake in New Carbon Processing, LLC to 45.9%, moving closer to the 50% target.
During the year, construction milestones were reached with completion of kiln assembly, installation of refractory lining, and initiation of the heat treatment process. In parallel, installation of back-end systems, including conveyors, bagging lines and silos, is underway, positioning the facility for commissioning and initial sample production.
To support this expansion, the company executed several capital-raising initiatives:
- a non-renounceable entitlement offer issuing 69.8 million Loyalty Options (raising approximately AUD 698,000)
- a share placement raising AUD 600,000
- issuance of 400,000 Convertible Notes convertible into 5.0 million shares.
Proceeds from these initiatives are being allocated towards further development of the Kentucky facility.
Plans for 2026
Carbonxt expects the Kentucky facility to enter commercial production in early 2026. The plant is forecast to boost group sales by almost 200% and provide access to the liquid-phase activated carbon market, which is significantly larger than the company’s current air-phase segment.
The facility is designed to deliver premium-grade products for wastewater treatment, PFAS filtration, and industrial emission control, aligning with tightened US EPA regulations.
The EPA has finalised strict limits for PFOA and PFOS in drinking water, requiring utilities to begin monitoring by 2027 and reach full compliance by 2031. The company noted that this regulatory clarity is speeding up procurement and planning throughout the sector, with heightened interest from water utilities and distributors looking for dependable domestic supplies of high-performance activated carbon.
The Kentucky facility will be key in addressing this demand, working alongside the company's two other active US production sites.
In the September 2025 quarter, Activated Carbon Pellet (ACP) sales increased by 11% compared with the prior quarter, while Powdered Activated Carbon (PAC) sales remained favourable, supported by deliveries under the ReWorld contract. These trends highlight consistent demand across the company’s product lines ahead of the Kentucky facility ramp-up.
Carbonxt plans to leverage its US-based operations and new production capacity to maintain revenue growth and operational efficiency in 2026, positioning the company as a key provider of engineered activated carbon solutions in the North American market.
