The Terrazzo Comeback:

Terrazzo is having a moment. Again.

Walk through any recently completed hotel lobby, co-working space, or flagship retail store and you will likely find terrazzo underfoot. The material that defined mid-century public architecture, fell out of fashion in the 1980s, and spent decades consigned to airport renovation projects has returned to the center of the design conversation.

But this time, the conversation has changed.

The architects and interior designers driving terrazzo’s resurgence are not simply nostalgic. They are asking harder questions: Where does the stone come from? What is the carbon footprint of the binder? Can the slab be recycled at end of life? And does the material’s story match the values of the spaces it occupies?

These questions are reshaping how surface materials are specified, manufactured, and marketed across the architecture and design industry. And they are creating a clear divergence between two categories of terrazzo: conventional products that rely on virgin quarried aggregate and standard Portland cement, and a new generation of eco terrazzo slabs built on reclaimed stone and low carbon binders.

The Problem with Virgin Aggregate

Traditional terrazzo is beautiful. It is also extractive. Most conventional terrazzo slabs use freshly quarried marble, granite, or glass aggregate. The quarrying process strips hillsides, generates significant dust and water pollution, and produces enormous quantities of waste stone that are typically dumped as landfill.

Meanwhile, the construction and demolition sector generates approximately 600 million tons of waste annually in the United States alone, according to the EPA. A significant portion of this waste is stone, marble, and granite: the exact materials that terrazzo manufacturers quarry from the earth at great environmental cost.

The disconnect is striking. The industry extracts virgin stone while simultaneously landfilling the same material from demolished buildings. Circular material flows offer a way to close this gap.

The Shift Toward Reclaimed Aggregate

A growing number of architects are now specifying terrazzo products that use reclaimed and recycled stone aggregate. The appeal is both environmental and aesthetic.

Reclaimed aggregate carries visual complexity that factory sorted virgin stone cannot replicate. Chips sourced from different quarries, eras, and geological formations bring a depth of colour and character that tells a richer material story. The variation is not a defect. It is a design asset.

From a sustainability perspective, reclaimed aggregate diverts material from landfill, eliminates the carbon emissions associated with new quarrying, and reduces the transportation footprint when aggregate is sourced regionally from demolition and fabrication waste streams.

When paired with low carbon cement binders (formulations that replace a portion of Portland cement with supplementary cementitious materials like fly ash, slag, or calcined clay) the embodied carbon of a terrazzo slab can drop by 30 to 40 percent compared to conventional products, without sacrificing compressive strength or durability.



What to Look for When Specifying Eco Terrazzo

Not all “eco” claims are equal. When evaluating terrazzo products for sustainability, architects and designers should look for several key indicators:

•      Reclaimed aggregate content by weight. The higher the percentage, the greater the diversion from landfill. Products with 80%+ reclaimed content represent best in class performance.

•      Environmental Product Declarations (EPDs): third party verified documents that quantify the product’s environmental impact across its full lifecycle.

•      Low carbon binder composition. Look for specific reductions in embodied carbon versus a conventional Portland cement baseline, ideally 30% or more.

•      VOC emissions testing, which is critical for indoor air quality, especially in healthcare, education, and hospitality projects pursuing WELL or LEED certification.

•      End of life recyclability. Can the slab be crushed and reused as aggregate at the end of its life, closing the material loop entirely?

•      Certifications such as Cradle to Cradle, ISO 14001, or equivalent third party environmental management standards.

These criteria matter because they separate meaningful environmental performance from surface level greenwashing. In a market where every material manufacturer claims sustainability, verifiable data is the differentiator.

A Case in Point: Alpine Inspired Reclaimed Terrazzo

One product that exemplifies this new direction is a slab recently developed by CoveringsETC called Engadin Creek. Named after the glacial creek beds of Switzerland’s Engadin Valley, it uses 85% reclaimed stone aggregate (grey veined marble, warm amber calcite, deep green serpentine, and near black obsidian fragments) set in an eco engineered cement matrix with 40% lower embodied carbon than traditional terrazzo.

The material story is drawn directly from the landscape. In the Engadin Valley, meltwater has scattered stone fragments across riverbeds for millennia, composing natural mosaics of extraordinary color and complexity. Engadin Creek translates that geological narrative into a surface material for floors, walls, countertops, and facades.

Each slab is unique. The aggregate variation is not randomized in a factory. It is a direct consequence of sourcing reclaimed stone from multiple origins. The visual result is a surface that feels both designed and discovered, intentional yet unrepeatable.

The product holds EPD certification, ISO 14001, and Cradle to Cradle Silver. It emits zero VOCs and is available in large formats up to 1200 × 2400 mm, enabling seamless, joint minimised installations.



Why This Matters for the Next Decade of Architecture

The built environment is responsible for approximately 40% of global carbon emissions, with materials and construction accounting for roughly 11% of that total. As embodied carbon regulations tighten (frameworks like the EU’s Level(s), California’s Buy Clean Act, and the UK’s RICS whole life carbon assessments) specifiers will increasingly need to justify every material choice with data.

Terrazzo, with its 100+ year lifespan, inherent durability, and now proven potential for high recycled content and low carbon binders, is positioned to be one of the most resilient surface materials of the next building cycle. But only if the industry commits to transparency, circular sourcing, and continuous improvement in binder technology.

The question for architects is no longer whether terrazzo belongs in contemporary design. It does. The question is whether the terrazzo you specify is worthy of the building it occupies, not just aesthetically, but ethically.
