Among manufacturers championing sustainability and quality is Colan Australia, whose basalt woven textiles stand out for both their environmental profile and distinctive aesthetic.
Unlike glass or carbon fibres, basalt fibre is made from a single ingredient: crushed basalt. The raw stone is melted and extruded into filaments without added resins, chemicals, or petroleum derivatives. This simplicity translates directly into environmental benefits—it reduces reliance on finite fossil fuels and limits the carbon footprint associated with material sourcing.
Basalt fibre production consumes significantly less energy and emits fewer greenhouse gases compared to petroleum-based alternatives. Research shows that glass fibers release 30–50% more gas during production, while basalt’s closed-cycle melting process uses minimal water and energy Such lean operating parameters also reduce water consumption, lowering stress on local waterways and power grids.
Basalt fibres are celebrated for their resilience. They resist acid, alkali, heat (up to ~650–800 °C), UV exposure, and corrosion—properties that contribute to longer asset service life and less frequent replacements compared to traditional materials.
Their inert nature means they’re non-toxic, non-carcinogenic, and safe to wear, handle, or discard. Better yet, end-of-life basalt fibre can be crushed and re‑used as aggregate in concrete or asphalt, closing the loop on material waste.
A standout selling point is basalt fibre’s high specific strength—often three times stronger than steel and outperforming E-glass in tensile load per mass. For composites, this means components can be lighter and still surpass safety and performance needs. Lighter materials result in reduced fuel consumption in transportation and machinery, thereby amplifying the long-term carbon benefits.
Colan’s basalt textiles are prized not only for performance but for their subtle, lustrous sheen. The natural volcanic silica and microcrystalline structure create a soft shine that enhances surface finishes and composites.
This muted lustre—in contrast to the matte dullness of glass or abrasive metal fibres—adds design allure without dyes or coatings, aligning with sustainable aesthetics.

Colan’s basalt woven fabrics support multiple weaves—plain, twill, satin—and customized orientations like unidirectional and stitched multiaxial. This versatility enables tailored sustainability solutions:
- Marine and automotive: lightweight, corrosion-resistant structural panels.
- Industrial insulation and fire seals: non-combustible, high heat tolerance.
- Electromagnetic shielding and high-temperature curtains: non-conductive with superior acid/alkali resistance
From sustainable surfboards to eco‑friendly rebar in infrastructure and aerospace-grade helmets, basalt fibre’s appeal lies in its green credentials without sacrifice to engineering demands.
Case Study: Colan Australia’s Basalt Fibre
Colan Australia offers a diverse basalt fibre range—from as low as 108 g/m² up to 2 126 g/m², in widths of 100–1 500 mm.
The plain, twill and satin weaves are meticulously crafted to elevate composite aesthetics and performance. Their basalt fabrics boast high tensile strength, excellent acid/alkali resistance, thermal durability, and are non-conductive—ideal for insulation, marine, structural, or automotive use.
But the environmental narrative is equally compelling. High-energy traditional composites are increasingly replaced by basalt textiles that support low-impact production, resource efficiency, and recyclability—all while delivering a naturally lustrous product.
Genelle Coghlan, Managing Director of Colan Australia, sums it up: “At Colan, we’re driven by both performance and planet-first innovation. Our basalt fibre range embodies this. Sourced from volcanic rock and woven into textiles with minimal environmental footprint, they offer engineers and designers a rare combination of natural lustre, strength, heat resistance—and genuine sustainability. We believe basalt composites are the future of eco‑responsible manufacturing.”
Outlook & Impact
Basalt fibre composites are not just niche science—they represent the future of sustainable material engineering. As global industries raise the bar on embodied carbon and lifecycle impact, basalt stands out as a low-energy, recyclable, non-toxic alternative capable of demanding technical applications. Its lustre and natural origins align beautifully with the growing designer demand for eco-conscious material narratives.
Colan Australia’s basalt fibre line not only meets technical benchmarks but champions a circular economy ethos—transforming volcanic stone into high-performance, visually appealing, long‑lasting composites with minimal waste.
In a world moving toward sustainability across disciplines, basalt fibre composites—led by innovators like Colan—are poised to play a major role. They offer a pathway to greener infrastructure, cleaner manufacturing, and responsibly crafted products—where lustre and longevity go hand in hand.
