What Is Zero Silica? Why It’s the Safest Option for Stone Benchtops in 2025
Introduction: A Safer Standard Modern Surfaces
As more homeowners, designers and builders begin to crave more than just aesthetics from their stone surface options, zero silica has become a viral buzzword in the stone benchtop world. In 2025, zero silica stone is rapidly becoming the new gold standard in kitchens, bathrooms, and commercial interiors as customers demand safer and smarter options.
In this article we will explain what zero silica really represents, its differences from traditional engineered stone, and how it has become the most secure and future-proof option when it comes to benchtop material not only in Australia, but worldwide.
What is Zero Silica?
Zero silica stone can be a type of artificially made surface that has fewer than 1 percent of crystalline silica. Crystalline silica is a mineral compound that when suspended in the air, presents a severe health hazard to employees who cut or polish stone products.
In contrast to conventional quartz-based engineered stone (which may include as much as 90 percent crystalline silica), zero silica substitutes are composed of natural minerals, ceramics, or porcelain, which are bonded together through high heat and pressure. These surfaces can resemble marble, granite or concrete, satisfying consumer needs for aesthetics. Most importantly however, due to its almost non-existent crystalline silica content, zero silica does not release hazardous dust into the air when worked on.
Respirable crystalline silica (RCS) is produced when crystalline silica is cut, ground and polished dry. These particles are so miniscule that they can penetrate through respiratory protection and go deep into the lungs causing:
- Silicosis: A severe and often fatal lung disease
- Lung cancer
- Chronic bronchitis
- Autoimmune diseases
In recent years there has been an epidemic of silicosis among young stonemasons and fabricators raising national concern and awareness. Thus, governments worldwide have taken notice and action, resolving to ban or restrict high silica engineered stone.
Australian Engineered Stone Ban (2024-2025)
Since 1 July 2024, the use, supply and installation of engineered stone with a silica content greater than 1 per cent has been prohibited in Australia. This law is mandated in many states, with full country-wide implementation by 1 January 2025.
Zero silica stone is legal, safe, and designated as the future. This is why it will soon become the standard for quartz benchtops.
Which Materials Can Be Considered as a Zero Silica?
Materials need to have <1 percent crystalline silica per weight to comply with the new standards and be considered “zero silica.” Typical choices are:
- Sintered Stone: Sintered stone is heat resistant and super durable made of compacted minerals and pigments with eye catching veining and finishes to closely match natural stone.
- Porcelain Slabs: Large-format porcelain is highly resistant to heat, scratches and stains. It has long been popular in Europe and is now readily available in Australia.
- Ceramic Composite Stone: Technologically advanced ceramic-based products are performance and safety engineered and are perfect to use on kitchen surfaces and splashbacks.
- Recycled Glass Benchtops (Low Silica Certified): Eco-friendly materials produced with the use of glass, resin, or ash can be also eligible - in the case that their silica concentration does not exceed 1 per cent.
Why Zero Silica is the Safer Choices in 2025
1. It Shields against Fatal Dust to Workers
Zero silica stone protects stonemasons, installers and fabricators, by removing the dangers of harmful silica exposure. No air scrubbers, sealed cutting booths or respirators needed - just peace of mind.
2. In Complete Concert with Australian Laws
The builders, retailers, and renovators that currently use zero silica materials are already in adherence with WorkSafe, SafeWork, and federal WHS laws. No danger of project delays, penalties, or lawsuits.
3. Child and Pet Safe
The zero silica slabs are hygienic, non-porous and contain no VOCs or allergens. Ideal in food-prep areas, bathroom sinks and family kitchens.
4. Durable as Quartz-More Durable?
sintered, and porcelain slabs are durable, keeping its integrity in heat and UV as well as resistant to stains and scratches. Thus, they are an ideal choice to be used both indoors and outdoors. They do not have to be sealed like some natural stones, and they do not require special cleaners.
5. Aesthetic Designs at No Compromise
Zero silica products available today are hyper-realistic in veining, having a matte or gloss appearance, and are available in a variety of colours ranging between modern looking concrete tones to more luxurious looking marble inspired whites and golds.
What to Look for in Determining Whether a Product is Zero Silica?
Always insist on your supplier to provide:
- Crystalline silica content certification adhering to <1% silica
- Material safety data sheet MSDS
- Product guarantee and handling manual
Other brands can mark products as low silica but fall outside of legal limits- ensure you get certified papers. Gen Stone promises to always provide proof of certification to its customers.
The Uses of Zero Silica Stone
Zero silica surfaces are not only versatile, durable, but also aesthetically beautiful. Popular uses include:
- Kitchen bench tops & splashbacks
- Shower walls & bathroom vanities
- Laundry rooms & mud rooms
- Hospitality fit outs & retail counters
- BBQ & outdoor kitchens
Concluding Remarks: Safe, Fashionable and Not Going Anywhere
Zero silica is no longer a trend in 2025, but rather the new standard of safe, modern and durable stone surfaces. As a homeowner contemplating a renovation, a builder overseeing compliance, or a designer specifying materials, selecting zero silica stone will ensure:
- Worker safety
- Peace of mind under the law
- Long lasting beautiful results
- The future of the construction industry as a healthier one
