Why zero silica matters
Beautiful surfaces should never come at the cost of human health. Here is the science, the regulation and the craft behind our commitment to zero crystalline silica.
Why zero silica matters
Beautiful surfaces should never come at the cost of human health. Here is the science, the regulation and the craft behind our commitment to zero crystalline silica.
California is changing the rules
In May 2026, California’s Occupational Safety & Health Standards Board voted to initiate emergency rulemaking to ban the fabrication and sale of engineered stone containing more than 1% crystalline silica — following Australia’s nationwide ban in 2024.
Confirmed silicosis cases in California since 2019, including 31 deaths
Proposed California threshold for crystalline silica in engineered stone
Crystalline silica in every EuroStone Zero surface, certified by our manufacturer Stone Italiana
EuroStone Zero surfaces are manufactured with 0% crystalline silica content as certified by Stone Italiana, our manufacturer, and are positioned to meet proposed California regulatory requirements. Based on manufacturer certifications and EPD documentation — consult current regulations for compliance requirements specific to your project.
Silicosis is preventable
Cutting and polishing high-silica engineered stone releases respirable crystalline silica dust — the cause of an epidemic of accelerated silicosis among fabricators. Zero silica removes the hazard at its source.
Ahead of regulation
California has moved to restrict engineered stone above 1% crystalline silica, following Australia’s nationwide ban. EuroStone Zero was engineered to exceed tomorrow’s standards, today.
Healthier indoor air
GREENGUARD Gold certification means low chemical emissions — cleaner air quality for the homes and workplaces our surfaces live in.
Crystalline silica by material
Not all surfaces are equal. Here is how common countertop materials compare on crystalline silica content.
Crystalline silica is linked to silicosis when inhaled during fabrication. Australia banned engineered stone above 1% silica in 2024; California voted to initiate similar rulemaking in May 2026. Ranges are indicative. Sources: OSHA, CDC/NIOSH, AIHA, manufacturer SDS.
From quarry waste to countertop
Every zero silica surface begins as recycled stone-quarrying waste and is transformed through a fully sustainability-driven production process.
Responsible sourcing
Selected suppliers sharing our sustainability principles and a commitment to quality from the source.
100% recycled minerals
Pre-consumer mineral aggregates reclaimed from stone-quarrying waste — completely quartz-free.
Plant-based resin
A 21% plant-based resin formulation reduces dependence on fossil resources while maintaining superior bond strength.
Responsible production
Multi-step processing at ISO 9001 certified facilities ensures quality, safety and recyclability at every stage.
High-tech pressing
State-of-the-art vacuum vibro-compression technology produces a finished slab with full-body consistency.
Zero silica vs traditional quartz
See how zero silica surfaces compare to conventional engineered quartz across every key metric.
Traditional Quartz
- 90–95% crystalline silica content
- Releases respirable crystalline silica dust during fabrication
- Requires specialised dust-control equipment (OSHA)
- Linked to the silicosis epidemic among fabricators
- Subject to proposed California restrictions (>1% silica)
- Virgin raw materials — not recycled
EuroStone Zero Silica
- 0% crystalline silica — verified by manufacturer
- No respirable crystalline silica dust during fabrication
- No specialised dust-control equipment needed
- The safest option for fabricators and installers
- Meets the proposed California <1% silica threshold
- 100% recycled pre-consumer minerals from quarry waste
