Australia Gas Cleaning Technologies Market Overview, 2031

Key Insights

• According to the research report, "Australia Gas Cleaning Technologies Market Outlook, 2031," published by Bonafide Research, the Australia Gas Cleaning Technologies Market is anticipated to grow at more than 5.51% CAGR from 2026 to 2031.
• Australia represents a technologically mature market for gas cleaning technologies, supported by major mining, metals, steel, cement, chemicals, oil and gas, power generation, waste treatment and manufacturing industries. The market is particularly influenced by the country's large resource processing sector, where dust, particulate matter, NOx, SOx, VOCs and other pollutants are generated from extraction, processing and combustion activities.
• Mining and metals are among the most important application areas. Iron ore processing, alumina refining, aluminum production, coal mining, mineral processing and steelmaking require particulate filtration, gas scrubbing and emissions monitoring systems. The large geographical concentration of resource processing facilities also creates demand for robust, high-capacity systems capable of operating in remote locations.
• Australia has a strong installed base of environmental control equipment, making replacement, retrofit and performance upgrades an important part of market demand. The National Pollutant Inventory collects annual emissions data from more than 4,000 industrial facilities across Australia and covers 93 substances, providing an extensive regulatory framework for industrial pollution monitoring.

Market Outlook

• Particulate control technologies are expected to remain a major segment because of Australia's large mining, minerals-processing, cement and metals industries. Bag filters, fabric filters, ESPs, cyclones and dust-collection systems are widely applicable across mineral handling, crushing, grinding, calcining, smelting and other industrial processes.
• Mining and mineral processing will remain major demand centers, particularly for dust suppression and collection, acid-gas treatment and emissions monitoring. Australia's continued investment in critical minerals processing is also expected to create opportunities for specialized gas-cleaning equipment in new processing facilities.
• The metals sector is another important opportunity. Australia's 2025 emissions projections identify the metal industry as the second-largest source of emissions within the industrial processes and product-use sector, contributing approximately 10 Mt CO₂e, or 32% of IPPU emissions.
• Cement and lime manufacturing will generate demand for particulate filtration and process-gas treatment as producers modernize plants and reduce emissions. In March 2025, the Australian Government committed A$24.5 million to support Boral's Berrima cement facility, with the project expected to reduce emissions by around 100,000 tonnes annually.
• Oil and gas, chemicals and industrial manufacturing will continue to support demand for VOC control, thermal oxidation, scrubbers, absorbers and continuous emissions monitoring.

Policies

• Australia's industrial air-pollution regulation is shared between the Australian Government and state and territory governments. Environmental approvals, emission limits and industrial operating requirements are therefore determined through a combination of federal and state-level frameworks.
• The National Pollutant Inventory provides a nationwide reporting framework covering 93 substances released to air, water and land. More than 4,000 industrial facilities report emissions and waste transfers annually, with state and territory regulators responsible for data collection and compliance.
• The Safeguard Mechanism is an important policy driver for large industrial facilities. Government data released in April 2026 showed that net emissions from Safeguard Mechanism facilities had declined 5.5% year-on-year and were more than 12% below levels when the reforms began. The policy is encouraging industrial operators to invest in technologies that reduce emissions at their source.
• Australia's climate policy is also supporting industrial electrification, energy efficiency and cleaner production. These changes can indirectly increase demand for upgraded gas treatment systems as industrial facilities modify combustion processes and production technologies.

Industry Statistics

• The 2024-25 National Pollutant Inventory contains emissions information from more than 4,000 facilities across Australia and tracks 93 substances, including nitrogen oxides, sulfur compounds, particulate-related pollutants, VOCs and hazardous substances.
• Australia's total net greenhouse-gas emissions were 466.4 Mt CO₂e in FY2023–24. The National Inventory Report covers emissions from energy, industrial processes, agriculture, waste and land-use sectors.
• For the year to December 2025, Australia's national emissions were estimated at 458.9 Mt CO₂e, down 2.1% from the previous year. However, emissions from industrial processes and product use increased 3.0%, primarily because of higher steel production.
• Australia's metal industry contributed approximately 10 Mt CO₂e in 2025, representing 32% of industrial process and product-use emissions. Chemical-industry emissions accounted for another 13% of the sector.

Segment Analysis

Australia Gas Cleaning Technologies Market By Technology
• Particulate control represents a major technology segment in the Australia gas cleaning technologies market, driven by the country's large mining, metals and steel, cement, power generation, and mineral processing industries. Mining, steel and metal processing, power generation, and petroleum refining are among Australia's major industrial sources of particulate emissions, including PM10 and other dust emissions. Baghouse filters, electrostatic precipitators, cyclones, cartridge filters, and dust collection systems are therefore widely relevant across heavy industrial operations.
• Gas scrubbing is an important technology segment because Australian industrial facilities generate acid gases, ammonia, sulfur compounds, chlorine, fluoride compounds, and other soluble pollutants. Chemical scrubbers are used across chemical processing, metal finishing, sewage treatment, and other industrial applications, while wet, dry, and semi dry scrubbing technologies are applicable to different gas streams. State environmental authorities provide specific guidance on chemical scrubbing for controlling acid gases, ammonia and other industrial emissions.
Australia Gas Cleaning Technologies Market By End-Use
• Power represents a major end-use segment for gas cleaning technologies in Australia because electricity generation, particularly thermal power generation, is an important source of industrial air emissions including NOx, SOx and particulate matter. Flue gas treatment systems, particulate collectors, scrubbers, and NOx-control technologies are used to manage emissions from combustion processes. State environmental authorities regulate industrial and power station emissions through licensing and air emission requirements.
• Chemicals represent a significant end-use segment due to emissions from chemical production, solvent use, storage, processing, and combustion. VOCs, acid gases, ammonia, particulate matter, and other process pollutants require combinations of scrubbers, adsorption systems, filters, thermal or catalytic oxidation, and mist-elimination technologies. Chemical scrubbing is specifically recognized in Australia as a suitable technology for industrial gas and odour treatment.



Australia Gas Cleaning Technologies Market By System
• New installation systems represent an important portion of the Australia gas cleaning technologies market, particularly for new mining and mineral-processing facilities, industrial plants, manufacturing facilities, waste-treatment infrastructure, energy projects, and refinery or chemical projects. New systems can be designed around the facility's process characteristics, pollutant profile, emission limits, and applicable state or territory environmental requirements.
• Retrofit/replacement systems account for a substantial share of demand because Australia has a mature installed base of mining operations, metal processing facilities, power plants, refineries, chemical facilities, cement plants, and other industrial assets. Existing gas cleaning systems are upgraded or replaced to improve pollutant removal efficiency, comply with revised environmental requirements, accommodate process changes, and extend equipment operating life. The continued regulation of industrial emissions through environmental licences and state-based emission requirements supports ongoing retrofit opportunities.
