The Ban of Caesarstone in Australia

Stone Industry Shakeup: The Inside Scoop on the Ban of Caesarstone in Australia

Caesarstone, a leading engineered stone manufacturer, is facing a significant challenge. In response to Australia’s potential ban on their engineered stone benchtops due to silicosis concerns, they have ramped up advertising. This serious lung disease is linked to the crystalline silica in these benchtops. As health experts, unions, and government officials debate a complete prohibition, Caesarstone suggests limiting silica content instead. The ongoing discussion underscores the delicate balance between industry interests and critical health and safety needs.

Caesarstone, a leading manufacturer of engineered stone, has initiated a strong advertising campaign in response to a potential ban on engineered stone benchtops due to health concerns over silicosis, a serious lung disease linked to crystalline silica in these products. This campaign comes as health experts, unions, and government officials debate the need for a ban to protect workers, with Caesarstone proposing a limit on silica content rather than a complete prohibition. The ongoing discussion highlights the challenge of balancing industry and economic interests with critical health and safety considerations​.

In this blog, let us explore the various dimensions of this critical issue. We’ll delve into the health risks associated with silicosis, understand the perspectives of those affected by the potential ban, and examine the regulatory landscape surrounding engineered stone. 

What is Engineered Stone?

Engineered stone, commonly used for kitchen benchtops, has recently become a focal point of health concerns, particularly due to its association with silicosis, a serious lung disease. This material, often preferred over natural marble for its durability and variety of designs, is made from quartz crystals bound together with resin. Despite its advantages in aesthetics and scratch resistance, engineered stone has been found to pose significant health risks to workers involved in its cutting and finishing.

Is Silicosis a pressing issue?

Silicosis, the primary health concern linked to engineered stone, is a long-term lung disease caused by inhaling fine dust containing silica (respirable crystalline silica, or RCS). This leads to lung scarring and can have debilitating and sometimes fatal consequences. This disease can be fatal, and exposure to silica dust also increases the risk of lung cancer and other respiratory diseases. Once engineered stone is installed, however, it does not pose any health risks to the inhabitants of the space. For workers cutting and shaping the stone, the risks can be significant.

The ban is primarily driven by concerns over silicosis risks associated with the manufacture of products containing crystalline silica. Caesarstone, however, has stated that it has been providing clear warnings about the risks of silicosis and safe handling procedures since the 1990s.

The Heart of the Controversy

Caesarstone argues that a total prohibition on engineered stone is unnecessary and excessive and may not effectively solve the silicosis issue. Instead, they propose a ban on manufactured stone with a crystalline silica concentration above 40 percent, suggesting that this action could be more targeted and effective in reducing risks to workers.

A major lawsuit in the US is using Caesarstone’s advertisements as evidence of what is claimed to be misleading and disgraceful conduct by the company. The lawsuit claims that Caesarstone, among other manufacturers, concealed the toxicity of their products. Caesarstone, in response to the lawsuit, has declined to comment as the matter is before the courts.

Health Implications

Health experts and industry regulators, however, have expressed concerns about the safety of engineered stone. Graeme Edwards, a former member of the national dust diseases taskforce and a Royal College of Physicians fellow, has criticized Caesarstone’s argument, stating that engineered stone is associated with a much higher risk than other crystalline silica-containing products. Edwards and others argue that the industry and regulators have failed to protect workers using engineered stone, indicating a need for stricter regulation or a ban.

The Australian Council of Trade Unions (ACTU) and other unions have called for a blanket ban on engineered stone, citing that there is no safe level of exposure to the dust generated from cutting the material. The final decision on the ban and its scope is yet to be made, with Safe Work Australia’s report on the matter expected to play a crucial role in informing the decision.

Related Studies

This call is backed by studies that estimate a significant number of workers are at risk of silicosis due to exposure to crystalline silica. 

1. A comprehensive study by Monash University found an alarmingly high prevalence of silicosis among workers in the stone benchtop industry. This study highlighted that the current safety measures and screening tests are failing to adequately diagnose and protect workers from the disease. 

2. One study, as reported by the CDC, highlighted that even though overall silicosis deaths decreased from 164 in 2001 to 101 in 2010 in the United States, deaths continued to occur among young individuals, with 28 deaths reported among persons aged 15–44 years during this period. Overexposure to respirable crystalline silica has been the identified cause.

3. Another study posted by the National Library of Medicine, conducted among artificial stone workers in Spain, emphasized the occupational risk factors contributing to the onset of silicosis. This study underlined the dangers associated with activities that involve inhaling silica compact dust, specifically in the context of artificial stone workers.

Economic Impact on the Ban

Caesarstone estimates that the Australian market accounts for around 18% of its revenue. The impending ban is expected to negatively impact its sales in the Australian market in the near term.

Business groups, including the Australian Chamber of Commerce and Industry, have raised concerns about the potential economic impact of a blanket ban on engineered stone. They argue that such a ban could lead to economic repercussions, affecting industries and businesses reliant on engineered stone. The fear is that a blanket ban might shift perceptions toward labeling materials as ‘safe’ or ‘unsafe’ without adequate consideration of their relative risks and benefits​​.

Health Impact on Workers

According to modeling by Curtin University, approximately 10,000 workers in Australia across various sectors are predicted to develop lung cancer, and up to 103,000 could be diagnosed with silicosis due to current exposure to silica dust at work.

The health risks associated with engineered stone, particularly silicosis, have been a major concern for workers’ safety. Unions and health organizations such as the Australian Council of Trade Unions and the Thoracic Society of Australia and New Zealand have strongly advocated for a ban on engineered stone, highlighting the high percentage of crystalline silica in these materials (up to 95%) and its link to the debilitating lung disease, silicosis. These groups argue that silicosis is entirely preventable and emphasize the importance of taking decisive action to protect the health and safety of workers handling these materials​​.

Industry and Workforce Impact

The engineered stone industry in Australia, which employs an estimated 8,000-10,000 workers, represents about 0.7% of workers exposed to silica and silicosis risks. Caesarstone has advocated for consistent silica levels across all building products and ongoing worker education and safety standards​​.

Government and Regulatory Response in Australia

Report Deliberation 

The Australian government, led by Workplace Relations Minister Tony Burke, is under scrutiny to release Safe Work Australia’s report on the engineered stone ban. This report is crucial in guiding the government’s response to the issue.

State-Level Responses

Various state governments have expressed differing viewpoints, with some states supporting a total ban on engineered stone. However, there’s also a recognition of the need to consider the potential unintended consequences of a complete prohibition.

National Meeting and Decisions

The final decision on the ban is expected to be made following a national meeting where the report’s findings and recommendations will be discussed among state and federal ministers.

Ban Announcement

On December 13, 2023, Australian federal, state, and territory governments jointly announced a decision to ban the use, supply, and manufacture of engineered stone slabs containing crystalline silica, including Caesarstone’s quartz-based products. This ban is set to take effect on July 1, 2024, in most Australian states and territories.

Company’s Response and Adaptation

In response to the upcoming ban, Caesarstone is planning to transition its product line to a new crystalline silica-free formulation, ensuring it retains similar fabrication and performance characteristics. They are also set to introduce new designs in their porcelain collection in the first half of 2024​.

Caesarstone’s Response

In response to the silicosis issue linked to engineered stone, Caesarstone has taken a stance that its products are safe if handled correctly. The company attributes the risks of disease to non-compliance with product handling requirements. Caesarstone has been providing warnings about the quartz content and risks since the 1990s and has focused on fabricator education. They argue for licensing the industry to ensure compliance rather than banning the product. In 2022, Ceaserstone launched a new low-silica-based product.
With the release of Safe Work Australia’s report on banning engineered stone, the situation still underscores the ongoing debate over balancing economic interests with worker safety in Australia’s blue-collar industry​


The debate over engineered stone versus its alternatives in the stonemasonry industry centers around balancing economic interests with worker safety. The use of engineered stone, popular for its aesthetic appeal and durability, has been linked to serious health risks, particularly silicosis, due to its high crystalline silica content. Alternatives like stainless steel, timber, and laminate, while offering varied aesthetics and functionalities, significantly reduce or eliminate this health risk.
