Australia has taken a significant step toward its industrial decarbonization goals and emission reduction targets by launching its first carbon refinery. This plant is designed to capture carbon dioxide (CO₂) emissions and transform them into practical materials for construction and manufacturing. The Myrtle demonstration plant, developed by clean technology company MCi Carbon, is located on Kooragang Island in New South Wales and operates alongside Orica’s ammonia production facility. The facility captures emissions that would otherwise be released into the atmosphere.
The project marks a shift in how carbon emissions are managed. Instead of just storing captured CO₂ underground, the refinery converts the CO₂ into valuable products used in different industries. The initiative's supporters believe it could reduce emissions from some of the most difficult sectors to decarbonize while creating new economic opportunities.
The opening of the facility aligns with Australia's intensified climate goals, which include reducing greenhouse gas emissions by 62% to 70% below 2005 levels by 2035. Heavy industries, such as cement, steel, chemicals, mining, and manufacturing, are under increasing pressure to reduce their carbon footprint, and technologies like carbon capture and utilization are becoming more relevant.
Carbon Emissions into Construction Materials
The process carried out at the Myrtle plant is called mineral carbonation. This technology replicates a natural geological process in which carbon dioxide combines with minerals and becomes permanently locked into solid materials. MCi Carbon has spent over 15 years developing this approach, which transforms industrial emissions into functional products.
The plant captures CO₂ generated during ammonia production and combines it with calcium- and magnesium-rich minerals. The carbon is converted into stable compounds, such as calcium carbonate, magnesium carbonate, and amorphous silica, through an accelerated chemical process. These materials can then be used in products such as concrete, plasterboard, glass, paper, paints, and adhesives.
Unlike traditional carbon capture and storage (CCS), which transports captured carbon into underground geological formations, carbon capture, utilization, and storage (CCUS) gives the carbon a second life as part of commercial products. This is a significant distinction because it creates the potential for carbon management to generate value.
Additionally, the technology can use industrial waste streams, including mining products, slag, and other low-value materials. By combining captured carbon with these resources, the system supports the principles of a circular economy, transforming waste from one industrial process into valuable inputs for another. This reduces dependence on new raw materials while reducing emissions.
The demonstration facility is expected to produce around 10,000 tonnes of mineral products and capture up to 2,500 tonnes of CO₂ annually. Although this volume is small compared to Australia’s approximately 400 million tonnes of annual emissions, the project demonstrates how carbon utilization technologies can operate on an industrial scale.
Carbon Utilization at Myrtle
The Myrtle facility is intended to be more than just a pilot project. Its primary purpose is to demonstrate the technical and commercial viability of converting captured carbon into useful products, setting the stage for larger facilities in the future. The Australian government has provided substantial support for this initiative through its Carbon Capture Technologies program. The government recognizes the importance of developing solutions for sectors where emissions are difficult to eliminate through electrification alone. Government officials have highlighted the project as an example of practical innovation that can reduce emissions and strengthen domestic manufacturing.
MCi Carbon is already planning its next step. The company is developing a factory-scale carbon refinery in Austria that will be capable of capturing up to 50,000 tonnes of CO₂ annually. Additionally, partnerships with industrial companies are exploring commercial facilities that could produce over 200,000 tonnes of low-carbon mineral products yearly by the end of the decade.
This project reflects a larger trend in global carbon markets and climate policy. As governments tighten emissions regulations and investors focus more on risks related to climate change, industries are seeking technologies that allow them to reduce their carbon footprint without sacrificing productivity or competitiveness. Carbon utilization offers one potential pathway by integrating emissions reduction directly into existing industrial supply chains.
Questions about scalability, costs, market demand, and verification remain, but the launch of Australia's first carbon refinery shows how captured carbon can be transformed from an environmental concern into a practical industrial resource. If future facilities succeed on a larger scale, technologies like the one used at the Myrtle refinery could help create lower-carbon supply chains and support the transition to a more sustainable industrial and circular economy.
