In this blog post, I will examine concerns regarding environmental pollution, human health, the local ecosystem, and economic impacts surrounding the Lynas Advanced Materials Plant in Malaysia, and consider whether the plant should be shut down in light of these issues.
The Malaysian government approved the establishment of the Lynas Advanced Materials Plant, and construction began in 2008. The government argued that attracting foreign investment and fostering the rare earth industry would contribute to economic development. However, Malaysian citizens, concerned about environmental pollution and health issues, strongly opposed this investment. Although the public fiercely opposed the plan through the non-governmental organization “Save Malaysia, Stop Lynas” (SMSL), the government supported the establishment and operation of the Lynas plant, which processes rare earth raw materials. The Lynas plant was completed and began operations in the Kuantan area of Pahang State, Malaysia, in 2012 and remains in operation to this day. Notably, in March 2026, the Malaysian government extended Lynas’s operating license for 10 years while imposing new conditions. Accordingly, Lynas was required to cease generating radioactive waste within the next five years and to reduce the radioactivity of previously generated residues through thorium extraction or other approved methods. However, as a citizen of Malaysia, I believe that even if it results in penalty fees or economic losses due to contract termination, the Lynas plant—which causes environmental pollution and ecological damage and could have a negative long-term impact on the economy—must be shut down.
First, let’s examine the environmental impact. The Lynas plant generates residues that may contain radioactive materials and various types of industrial wastewater during the processing of rare earth ore mined in Australia. In particular, the management and long-term disposal of residues—including those containing thorium—generated during the processing of rare earth ore have been one of the key points of contention surrounding the Lynas plant. Thorium is a naturally occurring radioactive element that primarily emits alpha particles; however, radon—which is produced as thorium decays—and its decay products can emit not only alpha particles but also beta and gamma rays. Therefore, to ensure the long-term safe management of radioactive residues, it is necessary to consider not only the shielding of storage facilities but also the potential for leaks and groundwater contamination, as well as long-term disposal methods. This is why controversy has persisted from the outset regarding the Linus plant’s residue storage facilities and permanent disposal issues. Although the Malaysian government has managed the storage facilities as temporary holding sites and continuously monitored radiation levels, how to handle the radioactive residues over the long term remains a critical issue.
In addition to waste, the wastewater generated at the Linus plant has also been a source of environmental concern. The processing of rare earth elements involves the use of various chemicals, such as sulfuric acid and hydrochloric acid, which results in the generation of industrial wastewater that must be treated. Since this wastewater may contain chemicals used in the process as well as various impurities, it has the potential to cause water pollution if not properly treated. In the environmental debates surrounding the Lynas plant, the treatment and discharge standards for industrial wastewater have been key points of contention. The Malaysian government and Linus have explained that they treat the wastewater and discharge it only after it meets relevant standards, and that water that comes into contact with radioactive materials is recirculated within the process. However, those concerned about environmental pollution have argued that long-term discharges and their impact on surrounding water systems must be continuously monitored, and that simply meeting legal discharge standards does not eliminate all environmental risks.
Controversy has also persisted regarding whether the Malaysian government’s regulations and oversight surrounding these issues are sufficient. The Lynas plant has been licensed and supervised in accordance with Malaysian legal regulations, and the government has been releasing monitoring data on radiation and the environment. In fact, Malaysia’s nuclear regulatory authorities are set to release radiation monitoring data related to Lynas in the Gebang and Kuantan regions as late as 2026. However, meeting regulatory standards is not the same as ensuring there are absolutely no long-term environmental risks. In particular, the issue of permanent disposal of radioactive residues was so significant that it was included in the permit conditions on multiple occasions. The operating permit renewed in 2020 included a condition requiring the company to begin developing a permanent disposal facility, and the regulatory conditions were subsequently amended again. In 2023, the permit was amended to allow Linus to continue importing raw materials and operating part of its process, on the condition that it conduct research and development to reduce the radioactivity of water leachate purification (WLP) residues. The new permit issued in 2026 stipulates that the company must cease generating radioactive waste within the next five years and dispose of existing residues using approved methods. These changes demonstrate that environmental management at the Linus plant is not a one-time issue but a matter requiring ongoing regulation and oversight.
Concerns regarding radioactive residues and wastewater are significant because they can affect the flora, fauna, soil, and water systems surrounding the plant. If radioactive materials are released into the environment, the potential for long-term impacts on soil and groundwater must be considered. Furthermore, if industrial wastewater is discharged into rivers, it can affect water quality and aquatic life, impacting not only organisms in the water but also riparian vegetation and the surrounding ecosystem. In particular, if chemicals alter the chemical properties of the soil, they can have a negative impact on plant growth. This is precisely why the ecosystems of the Balok River and the nearby coastal areas have become major concerns in the environmental debate surrounding the Linus plant. If it is difficult to completely rule out the possibility of damage to the local ecosystem, then even if the conservation value of the area where the factory currently stands is relatively low, the long-term impact on the surrounding soil, water systems, vegetation, and wildlife must be considered. Therefore, I believe that closing the factory is preferable to continuing its operation in order to minimize potential environmental risks.
Next, let us examine the adverse effects on human health. First and foremost, we must consider the potential health risks posed by radiation that may be emitted from radioactive residues. The effects of radioactive materials on the human body vary depending on their type, quantity, and route of exposure; excessive exposure to radiation can damage cells and DNA. In particular, exposure to high levels of radiation can damage or destroy cells, and long-term exposure to radiation can increase the risk of cancer. Furthermore, radiation-induced DNA damage can affect the normal functioning of cells. Therefore, if radioactive residues are not properly managed, they can pose a potential health risk to local residents and workers. However, claims that the operation of the Linus plant has actually led to an increase in specific diseases among nearby residents or workers should not be taken as fact, as they must be verified through separate epidemiological studies. The debate surrounding the radiation safety of the Linus plant is also significant in that it underscores the need to evaluate these potential risks in conjunction with actual exposure levels.
People may be affected not only by radioactive residues but also by wastewater generated by the plant. This does not refer solely to cases where contaminated water is directly consumed or used. If heavy metals or other harmful substances contained in the wastewater enter water systems, they may accumulate in aquatic organisms, and people may be indirectly exposed to these substances by consuming contaminated fish or seafood. Furthermore, if contaminated water is used for agricultural purposes or seeps into the soil, it may also affect crops. Considering the possibility that harmful substances released into the environment in this way could be transmitted to humans through the food chain, proper wastewater treatment and continuous environmental monitoring are of the utmost importance. Consequently, since the possibility of harmful substances accumulating in aquatic life or crops cannot be completely ruled out, wastewater management must also be strictly enforced to protect human health.
Furthermore, despite these environmental concerns, the government has authorized and supported the establishment and operation of the Lynas plant on the grounds of economic benefits. The government and Lynas have argued that the rare earth industry contributes to the development of Malaysia’s high-value-added industries, attracts foreign investment, and creates jobs. In fact, Linus has stated that, as of 2022, it had created approximately 4,600 direct and indirect jobs in the Malaysian economy and contributed approximately 4.8 billion ringgit to Malaysia’s gross domestic product since 2013. It also announced that Linus Malaysia employed more than 850 staff members in 2024. Therefore, the figures cited in the original text—annual revenue of over 3 billion won and approximately 300 jobs—are not appropriate for describing the current situation. However, does the Lynas plant have only positive economic impacts? This cannot be taken for granted. To assess the plant’s overall impact on the local economy, one must also consider the development of surrounding areas, its effects on the fishing and tourism industries, and the costs associated with environmental management and remediation.
It has been argued that concerns regarding the management of radioactive residues and environmental risks, as mentioned above, could impose restrictions on land use and development around the plant. In particular, the Gebang Industrial Area, where the Linus plant is located, is close to the port and serves as a hub for the chemical and materials industries. In fact, industrial facilities operated by large chemical companies, such as BASF PETRONAS Chemicals, are in operation near the Linus plant, and the expansion and restructuring of production facilities have continued in this area. Therefore, it is difficult to conclude that the Linus plant has made all investment in the surrounding area impossible. Rather, the current industrial zone has formed a complex industrial ecosystem where multiple companies coexist. Nevertheless, if uncertainty remains regarding the long-term management and disposal of radioactive residues, the possibility of additional burdens on land use and new investment must be considered. Furthermore, since one must compare not only the direct employment provided by the Linus plant but also the employment and added value that could result from attracting other industries, the economic impact of a single plant should not be judged solely by the number of jobs created.
That is not all. We must also consider the possibility that the wastewater could hinder the development of the fishing industry in the surrounding areas. If pollutants from contaminated rivers flow into the ocean, they could impact the marine environment; furthermore, if concerns about water quality or the safety of seafood increase, this could negatively affect the incomes of those engaged in fishing. If there are people in the vicinity of the Linus factory who depend on fishing or the seafood industry, the mere perception of environmental pollution could lead to a decline in the sales and consumption of seafood. Furthermore, if it becomes difficult to continue fishing in areas of concern, fishermen may have to move to more distant waters, which could increase time and fuel costs. Ultimately, it must be recognized that, regardless of actual pollution levels, environmental anxiety can affect public confidence in seafood and the competitiveness of the local fishing industry. Therefore, when assessing the impact of the Linus plant’s operations on the fishing industry and the local economy, it is necessary to continuously monitor actual water quality and seafood safety data while also considering the long-term economic costs.
Concerns regarding radioactive residues and industrial wastewater from the Linus plant could also affect the tourism industry.
This is because increased public perception of risks associated with radioactive materials or chemicals can negatively impact efforts to develop the natural environment as a tourism resource or attract tourists. In particular, since tourists place a high priority on a clean natural environment and safety when choosing a vacation destination, regions where environmental pollution controversies persist may see their image as tourist destinations weakened. In the past, claims were also made that nearby tourism development projects were affected during the construction of the Linus plant. However, it is difficult to make definitive statements regarding claims such as whether a specific resort project was directly canceled due to the Linus plant or exactly how many jobs were lost as a result, as these would require separate verification of the project records from that time. Nevertheless, it is essential to fully consider the possibility that if negative perceptions of environmental pollution persist over the long term, tourist visits and investment in the tourism industry could decline.
Since restoring a damaged environment entails enormous costs, environmental pollution not only hinders economic development but can also cause economic losses in the long term. If radioactive materials are released into the environment, significant costs are required to recover and safely manage the contaminated materials, and ongoing costs are incurred to establish facilities for the long-term storage and disposal of radioactive residues. Furthermore, restoring rivers or soil contaminated with chemicals to a state close to their original condition may require lengthy investigations and remediation efforts. Therefore, we must not only calculate the investment, employment, tax revenue, and industrial benefits that the Linus plant could generate but also take into account the costs required for environmental management and restoration. Even if economic benefits exist, if the long-term social costs resulting from environmental damage outweigh them, the economic feasibility of the project must be reevaluated.In summary, it is difficult to fully assess this issue based solely on the government’s initial explanation that the Lynas plant would not only avoid damaging Malaysia’s environment or harming wildlife but would also contribute to economic development. The Lynas plant has contributed to the development of Malaysia’s rare earth industry, as well as to employment and investment attraction, and remains in operation today. In March 2026, its operating license was extended for 10 years; however, new conditions were imposed requiring the plant to cease generating radioactive waste and to dispose of existing residues within the next five years. This demonstrates that the environmental issues surrounding the Lynas plant are not a thing of the past but rather a problem that must be continuously managed in the present. The radioactive residues and wastewater from the Lynas plant have raised concerns about the environment, the ecosystem, and human health, and could also incur potential costs in economic areas such as local fisheries, tourism, and land use. Of course, based solely on current scientific data, it cannot be conclusively determined that the Lynas plant has directly caused an increase in diseases among nearby residents or has actually caused all the environmental damage. However, given the ongoing concerns regarding the long-term management of radioactive residues and the potential for environmental pollution—as well as the fact that the government has even amended the operating permit conditions to address these issues—stricter management and verification are necessary. Therefore, if we fully consider the long-term risks and costs that could affect the environment, human health, ecosystems, and the local economy, I believe we should consider fundamental measures—including closure—rather than continuing the operation of the Linus plant.
