Mercury may no longer be used widely in modern industry, but across Australia, its legacy continues to surface in ways that demand attention.
From ageing oil and gas infrastructure, and decommissioned industrial facilities to laboratory equipment, dental amalgam waste and historical stockpiles, mercury remains present in waste streams that require specialist management. Unlike many other materials, mercury does not degrade or neutralise over time. If not properly treated, it remains a permanent environmental and human health risk, capable of persisting for generations.
As Australia strengthens its environmental framework and aligns with international agreements such as the Minamata Convention on Mercury, the focus is evolving. The challenge is no longer simply containing mercury safely, but ensuring it is permanently removed from circulation in a way that eliminates future risk. This shift is placing renewed importance on Australia’s ability to manage its own mercury domestically, rather than relying on long-term storage or offshore pathways.
A legacy issue still emerging today
Although mercury has been phased out of most modern applications, its historical use was widespread across mining, oil and gas, healthcare, manufacturing and research. It is often discovered unexpectedly, embedded within old processing equipment, contaminated components, or legacy waste materials that have remained undisturbed for decades. At the same time, ongoing industrial activity continues to generate mercury-containing waste, particularly within gas processing and laboratory environments.
Historically, Australia has had limited options for managing elemental mercury once recovered. In many cases, the material has been stored indefinitely, requiring ongoing monitoring and regulatory oversight, or transported long distances for treatment. Both approaches present challenges. Storage prolongs liability, while export introduces additional risk, cost and complexity.
Developing domestic capability to permanently treat mercury represents a step forward in resolving this long-standing issue.
Specialist capability built over three decades
EcoCycle, part of the EcoCycle Group, has played a central role in mercury recycling in Australia since its establishment in 1996. While the Group has expanded into batteries, e-waste and advanced material recovery, EcoCycle was founded on the management of mercury and other highly regulated hazardous materials.
Over nearly three decades, the company has built specialised expertise in handling mercury safely, supported by purpose-built infrastructure and strict environmental controls. This includes national collection capability, compliant transport systems and licensed processing facilities designed for hazardous materials.
Jason Zorzut, EcoCycle Group’s national operations manager, said the need for permanent solutions has never been clearer.
“Mercury is not something you can simply store and forget about,” he said. “It remains a risk for as long as it exists in its elemental form. What’s critical is being able to permanently stabilise it, so it can no longer pose a threat to people or the environment. That is what proper end-of-life treatment achieves.”
Moving beyond containment
At the centre of this approach is stabilisation. Elemental mercury is a liquid metal that can vaporise at relatively low temperatures, making it inherently difficult to manage through storage alone. Without treatment, the potential for environmental release remains.
EcoCycle has invested in specialised stabilisation technology that enables mercury to be chemically converted into mercury sulphide, a solid, stable compound that cannot re-enter the environment. This process fundamentally changes the mercury’s chemical structure, removing its volatility and reducing its risk profile. Undertaking this process within Australia ensures the material remains under Australian regulatory oversight, with traceability from collection through to final disposal. It also eliminates the need for export, providing industry with confidence that mercury waste generated domestically can be responsibly resolved within Australia.
Supporting industry across the country
Mercury waste arises across a diverse range of sectors, from heavy industry and resources to healthcare, government and infrastructure. EcoCycle works with organisations across oil and gas, mining, manufacturing, laboratories, defence and environmental remediation, providing a compliant pathway for managing mercury safely. This capability is important as Australia continues to modernise infrastructure and redevelop former industrial land, where legacy contamination may still be present. Having access to specialist treatment allows mercury to be addressed immediately, rather than becoming an ongoing liability.
Zorzut said domestic capability plays a critical role in strengthening Australia’s overall hazardous waste management framework.
“Having the ability to manage this element within Australia means organisations can deal with the issue directly and responsibly,” he said. “It removes uncertainty and ensures the material is handled in line with Australia’s environmental standards from start to finish.”
Australia’s obligations under the Minamata Convention reinforce the importance of environmentally sound mercury management, including ensuring mercury is permanently removed from circulation. This reflects a broader shift towards accountability and lifecycle responsibility, where hazardous materials must be managed in a way that prevents future environmental harm. By investing in stabilisation infrastructure, EcoCycle is helping to support this transition, ensuring this substance can be permanently treated under Australian environmental controls.
Resolving a legacy for the future
As Australia continues to address its industrial legacy and strengthen its environmental standards, mercury will continue to emerge as part of that process. Ensuring there is a safe and permanent domestic solution in place is essential, not only for compliance, but for protecting future generations.
As part of the EcoCycle Group, EcoCycle continues to play a specialised role in managing complex and hazardous materials that require more than conventional recycling approaches.
Through long-term investment, technical expertise and national capability, the company is helping Australia move beyond simply managing mercury, towards eliminating its risk entirely.
