Adbri - Birkenhead

The EPA initially approved the RDF trial proposal and the Adbri Kiln RDF Trial – Pre-Trial Report – 26 May 2026 on 6 July 2026.

The EPA was notified that the RDF Feed System to the Cement Kiln encountered commissioning issues, limiting the company’s ability to complete the approved trial program within the original timeframe.

Adbri has subsequently requested an amendment to the trial period to allow completion of the approved trial program. The EPA has assessed the application and approved a new trial with the same conditions as the prior approval. The revised trial period will now end on 27 October 2026.

While the end date of the trial will change, the number of hours that the trial will operate remains the same, as is the amount of RDF to be used. All other aspects of the trial in relation to testing, monitoring and community safeguards remain unchanged.

As the state’s independent environmental regulator, the EPA will ensure that the trial continues to be undertaken safely and is monitored in line with the approvals, including process stability, emissions assessments, and the uniformity / suitability of RDF.

For the duration of the trial Adbri must continue to implement additional air quality monitoring, including additional nitrogen dioxide monitoring and odour assessments in the local community.

Since the commencement of the trial, EPA staff have conducted announced and unannounced inspections of the Adbri facility, the Birkenhead and Peterhead areas and the RDF production site. As of the 19^th August 2026, EPA monitoring and inspection of the trial has confirmed that it has been conducted in accordance with EPA approvals. The EPA will continue to monitor the facility for the duration of the trial. In addition, EPA air quality monitoring is continuing in the adjacent community, as is localised odour assessment work on the LeFevre Peninsula by EPA field staff.

EPA licence 1126 (Adelaide Brighton Cement Limited) provides clear protocols for the trialling of alternative fuels and raw materials (AFRM). Adbri is required to submit a pre-trial report outlining the duration and nature of the trial process, the nature of the RDF, the environmental emissions assessment and the production of a post-trial report at the completion of the trial.

View the Adbri Kiln RDF Trial – Pre-Trial Report – 7 August 2026 for more information.

The EPA’s regulatory focus is to assess and consider whether trials can be undertaken safely and that they are accurately assessed against required outcomes (i.e process stability, emissions, uniformity of AFRM). Importantly, the trial proposal assessment focused on ensuring no detrimental increase in key pollutants (ie inorganic oxides, heavy metals, organic emission compounds and volatile organic and polyaromatic hydrocarbons) as per the trial protocol.

During the trial period the EPA requires Adbri undertake additional monitoring of odour in the community by an external specialist odour consultant as well as additional nitrogen dioxide (NO₂) community monitoring for the period of the trial.

Completion of the trial does not constitute EPA approval for the ongoing use of RDF in the Birkenhead Cement Kiln or a variation of the existing licence.

The Refuse Derived Fuel (RDF) Standard

The EPA's Standard for the Production and Use of Refuse Derived Fuel (the RDF Standard) provides information to support resource efficiency and the beneficial recovery of energy from waste by the combustion of refuse derived fuel in an industrial process. This standard includes reference to the Waste Hierarchy, which outlines that the production and combustion of RDF is viewed as a recovery of energy activity and is seen as an alternative to disposal (the least preferable option) but should not be at the expense of preferable options, including waste avoidance or closed loop recycling.

Current RDF Use in the Calciner

The Birkenhead plant is currently authorised to use up to 32 tonnes per hour (tph) of RDF into its Calciner with a maximum plastics content in the RDF of 20%. The RDF fuels the calciner, and together with natural gas operates between 850 – 890 degrees C. At this temperature limestone is decarbonised to lime (with carbon dioxide emitted) and the lime and other raw materials combine together and are transferred to the main rotary kiln where the cement clinker is formed.

Manufacture and Quality Control of the RDF

The EPA requires the RDF currently used in the calciner to meet the RDF Standard. All proposals for production and use of refuse derived fuel must be approved by the EPA.

The quality and consistency of the RDF must be maintained via a quality control and quality assurance (QC/QA) programme at the producer. This testing program is a key component of Adbri’s Recovered Product Plan (RPP) and the producer’s Environmental Management Plan (EMP) both of which have been approved by the EPA and the 20% maximum plastics content confirmed via sampling and analytical reports.

The approved calciner RDF product is a shredded mixture of timber, paper, cardboard, plastics, and other inert fibrous materials. The RDF is trucked to the Birkenhead plant on a “just-in-time" basis.

Frequently Asked Questions

Why has the trial window been amended?

The trial period has been revised after Adbri encountered commissioning issues with its RDF Feed System to the Cement Kiln, limiting the company’s ability to complete the approved trial program within the original timeframe.

Adbri has subsequently requested an amendment to the trial period to allow completion of the approved trial program. The EPA has assessed the application and approved a new trial with the same conditions as the prior approval. The revised trial period will now end on 27 October 2026

No other parameters of the originally approved trial will change, including the number of hours that the trial will operate and tonnages of RDF to be used.

How many hours will the trial run for now?

The trial is split into two stages, each with specific tasks and timeframes.

Stage 1 will occur across a 10-week period taking up to 96 non-continuous operating hours. The purpose of Stage 1 is to set up and confirm system capability of the RDF delivery and feed system.

Stage 2 will occur across a 4-week period, taking up to 72 non-continuous operating hours. The purpose of Stage 2 is to use RDF at commercial conditions while stack emissions testing is undertaken at different feed rates.

Was the community consulted in the change to the trial window?

Adbri is expected to continue to engage with the community in accordance with the trial conditions. The level of community engagement relating to the trial is unchanged from the original trial approval.

What is refuse derived fuel (RDF) and why is it used?

The RDF currently used in the Birkenhead calciner is an engineered fuel manufactured by Veolia ResourceCo at its dedicated facility in Wingfield and is comprised of Commercial and Industrial Waste (C&I), Construction and Demolition Waste (C&D) and Municipal Solid Waste Hard-Waste (MSW HW). The final RDF product is a shredded mixture of timber, paper, cardboard, plastics, and other inert fibrous materials. 

The Birkenhead plant is currently authorised to utilise up to 32 tph of RDF into its Calciner with a maximum plastics content in the RDF of 20%. This equates to approximately 50% substitution of its main natural gas supply via the utilisation of refuse derived fuel (RDF). The RDF fuels the calciner, which operates between 850 – 890 degrees C.

How is the current RDF quality and consistency checked?

The EPA requires Veolia ResourceCo and Adbri to ensure the quality and consistency of the RDF is prepared and maintained to a specification and regulates this requirement in their licence via the preparation of an Environmental Management Plan (EMP) and Recovered Product Plan (RPP) respectively. The quality control and assurance (QC/QA) programme at Veolia ResourceCo and at Adbri’s Birkenhead National Association of Testing Authorities (NATA) accredited laboratory is achieved via a sampling, testing, and analysis program. This testing program is a key component of Adbri’s RPP and Veolia ResourceCo’s EMP, both of which have been approved by the EPA and the 20% maximum plastics content confirmed by the EPA via sampling and analytical reports provided.

How are emissions monitored when RDF is being burned?

The EPA requires Adbri to undertake specific stack emissions testing during any RDF trial period to measure the mass emission rate and concentration of the combustion emission pollutants. The suite of compounds specified in the licence (Schedule Y-1) are targeted to those pollutants associated with the use of RDF in the combustion process. These include inorganic and organic emissions compounds, chlorine and chlorinated hydrocarbons, heavy metals, polyaromatic hydrocarbons, dioxins and furans.

The stack testing over the period since commencement of RDF use in 2003 has demonstrated that the Environment Protection (Air Quality) Policy, 2016 emission criteria have been met. Additionally, the ambient emission levels in the local community must meet the National Environment Protection Measure (NEPM) for Nitrogen Dioxide, Sulphur Dioxide, Carbon Monoxide, Particulates PM10 and PM2.5 which are designed for ambient air quality that is protective of health. To date, Adbri has demonstrated that NEPM standards have been met for the use of RDF.

How much plastic is allowed in the RDF used by Adbri?

The EPA approved the original use of RDF in the Birkenhead Calciner in 2003 at a rate of 10 tonnes/hr with a maximum plastics content of 10%. The approval followed a closely monitored trial by Adbri with stack testing conducted on both the calciner and kiln, which reported no detrimental increase in inorganic oxides of the key pollutants and no increase in organic emission compounds and volatile and polyaromatic hydrocarbons. There was also no detrimental change in the heavy metal emissions relative to natural gas usage (which was the primary fuel).

In July 2017, the EPA approved an increase of RDF to 15 t/hr with a maximum plastics content of 20% following a successful trial of the RDF in the calciner at the higher rate. The stack testing program during the trial analysed Nitrogen Oxides, Sulphur Dioxide and Carbon Monoxide emissions, heavy metals, and organic emissions as well as dioxins and furans. The trial demonstrated no detrimental emission levels compared to the previous emissions for these compounds.

The current licence permits up to 32t/hr of RDF to fuel the calciner, with a maximum plastics content of 20%. In practice, the calciner operates at around 25t/hr.

Does the EPA conduct air quality monitoring in Birkenhead?

The EPA conducts real-time monitoring in Birkenhead at its Le Fevre #1 air quality monitoring site and at North Haven at its Le Fevre #2 site. This monitoring is for the smaller health-impacting particles less than 10 micrometres in diameter (PM10) and particles less than 2.5 micrometres in diameter (PM2.5) in the ambient air as part of its continuous air quality monitoring program across metropolitan Adelaide. One micrometre (µm) is 1 millionth of a metre or 1 thousandth of a millimetre.

Real-time public access to EPA data is available by visiting its Air quality monitoring | EPA

The EPA requires Adbri to undertake air quality monitoring in the community for Total Suspended Particulates (TSP), PM10 and PM2.5, and also Nitrogen Dioxide.

What are the processes following the Adbri pre-trial outcomes?

Following the trial, a post-trial written report is required to be submitted to the EPA within 90 days. A post-trial report would include results of stack testing and modelling, process stability and uniformity of alternative fuels and raw materials.

Following a successful post-trial assessment, Adbri may seek a process change application in accordance with conditions A5 and/or A6 of EPA licence 1126, for ongoing use. Development assessment requirements may also be triggered.

Odour on the Le Fevre Peninsula

The Le Fevre Peninsula is home to a diverse mix of industrial, commercial, and port-related activities. Potential sources of odour include heavy manufacturing, power stations, hydrocarbon and fuel storage facilities, bitumen storage and handling, fuel service stations, light industry, port and shipping operations, and transport and logistics activities. Vehicle emissions and domestic wood heaters can also contribute to local odour.

What is the EPA doing?

The EPA is aware of community concerns regarding odour on the Le Fevre Peninsula and is actively investigating potential sources and correlating odour complaints with wind and meteorological data. We are continuing to undertake odour detection work to better understand the nature, distribution, and potential sources of odour in the region. The EPA works closely with its licensed facilities, to ensure they comply with the conditions of their EPA licence and implement reasonable and practicable measures to minimise emissions and off-site impacts. The EPA applies a range of approaches to regulating odour including site inspections, compliance activities, and localised ambient air quality monitoring.

Why odour is more noticeable in winter?

During the cooler months, atmospheric conditions called temperature inversions can occur. Temperature inversions are especially common at nighttime and early morning.

Normally, warm air near the ground rises and helps disperse odours through the atmosphere. During a temperature inversion, a layer of warmer air traps a cooler air layer near to the ground, limiting vertical air movement. Combined with calm to light winds, this can trap odorous air closer to ground level and reduce dispersion upwards hence allowing the odour to propagate laterally across the ground. This makes odours more noticeable and persistent. Watch this short video for a simple explanation of temperature inversions and how they influence air movement and odorous air.

How you can help

Community reports play an important role in helping the EPA identify and investigate odour sources.

If you experience odour on a regular basis, you can help the EPA by recording your observations in an EPA odour diary. Odour reports can also be submitted through the EPA’s online odour reporting portal. Detailed information from community members assists the EPA to:

• assess potential sources and target its compliance activities
• identify trends or recurring issues
• compare reports with site operations or environmental conditions
• determine whether further investigation or regulatory action may be required.

The EPA undertook a 12-month air quality monitoring campaign on the Le Fevre Peninsula from September 2024 to September 2025 with two mobile stations set up in Birkenhead and Peterhead in addition to the existing EPA permanent monitors. The purpose of the campaign was to provide a more detailed understanding of local air quality conditions in relation to particulate matter (PM) and to identify any potential impacts to PM from local sources, including the Adbri Birkenhead Cement Facility.

The EPA analysed several parameters including Total Suspended Particulates (TSP), particles with an aerodynamic diameter of 10 micrometres (µm) or less (PM10), dust deposition and dust composition analysis as part of this campaign. Particles with an aerodynamic diameter of 2.5 µm or less (PM2.5) were measured at the EPA’s existing Le Fevre 1 and Le Fevre 2 monitoring stations.

The Birkenhead and Peterhead Air Quality Monitoring Campaign fact sheet summarises the results of the 12-month campaign.

To ensure a continued focus on environmental improvements at the Adbri Birkenhead site, the Environment Protection Authority (EPA) required Adbri to develop and implement an Environment Improvement Programme (EIP). An EIP is a regulatory tool under the Environment Protection Act 1993 that requires licensees to specify the actions that they will take to achieve compliance with the general environmental duty. EIPs must include a clear and demonstrable schedule of the improvements the licensee will implement.

In accordance with its EPA licence, Adbri was required to submit a revised EIP to the EPA’s satisfaction by 31 May 2024. Adbri’s EIP was submitted by this date, however, it was deemed unsatisfactory by the EPA. Based on this and a significant dust emission event from Adbri during May, the EPA issued an Environment Protection Order which required Adbri to submit a revised EIP with significantly tighter dust control commitments, by 31 October 2024.

In determining the actions committed to in its EIP, Adbri engaged a suitably qualified expert to undertake a detailed assessment of options to prevent or minimise emissions from its site. A number of recommended options were identified in this process, and consideration of the actions, timeframes and milestones of these options have been considered in the revised EIP.

The EPA also required that Adbri undertake public consultation with the community as a key part of developing its revised EIP.

Two additional community air quality monitoring stations were also established during September 2024 by the EPA (Naval Reserve, Birkenhead and Peter Nicholls Reserve, Peterhead) to better understand the nature of local dust impacts.

The EPA formally approved Adbri’s EIP on 15 November 2024 and a copy is available here.

The EPA attended the quarterly Adbri Community Liaison Group meeting on 2 September 2024 and provided a presentation to the CLG. The presentation provided an update on the work that the EPA has undertaken since the previous update to the CLG on 22 July 2024.

The presentation is available here.

On Monday 19 August community members took the opportunity to drop in and speak one-on-one with staff from the EPA and SA Health about their concerns regarding dust from Adbri Birkenhead. Factsheets were available providing an update on the EPA’s regulatory response and general information in response to health concerns raised. Both factsheets are available below:

• SA Health factsheet – Air quality and your health
• EPA factsheet – Dust from Adbri Birkenhead

Following Adbri's Birkenhead Community Liaison Group (CLG) meeting on Monday 3 June, an additional meeting was held on Monday 22 July. The EPA arranged for SA Health representatives to attend the 22 July CLG meeting to provide responses to questions from the community about the particles released during the recent dust event, and to provide general information in response to health concerns raised. The EPA also provided an update at the 22 July CLG meeting. Both presentations are available below:

• SA Health presentation - Adbri Birkenhead - 22 July 2024
• EPA presentation - Adbri Birkenhead - 22 July 2024

The EPA collected deposited dust samples on 28 and 29 May from windowsills, door frames, and the tops of bins at 19 different locations around the Adbri Birkenhead facility. These samples were then analysed by a certified laboratory for mineralogical composition using semi-quantitative x-ray diffraction (XRD).

The XRD results highlighted calcite, hatrurite, and quartz as the three most abundant minerals present in these dust samples.

See below for a summary of the results or download the full report:

• Mineralogical Report - AN1099

Calcite

Calcite (CaCO_3, a major component of cement) generally decreased with increasing distance from the Adbri facility. The amount (weight %) of calcite in the samples collected ranged from 10% to 52%.

Amount of calcite by address – the blue circles are proportional to the % calcite component.

Hatrurite

Hatrurite (Ca₃SiO_5, an important phase in cement clinker) also generally decreased or was not detected with increasing distance from the Adbri facility. The amount of hatrurite in the samples ranged from 2% to 30% and was not detected in five samples (green circles).

Amount of hatrurite by address – the blue circles are proportional to the % hatrurite component.

Quartz

Quartz (SiO_2, the most common mineral on earth and a major component of normal dust) generally increased with increasing distance from the Adbri facility. This indicates more natural/normal dust moving away from the Adbri facility. The amount of quartz in the samples ranged from 16% to 71%.

Amount of quartz by address – the blue circles are proportional to the % quartz component.
