From Insulation to Architectural Profiling: How Recycled Polystyrene is Redefining Sustainable Design

Australia’s building and design industries are proving that sustainability and innovation can go hand in hand. Through a shared commitment to recycling and circular manufacturing, Foamex, StyroCycle, and The Cornice Store are showing how expanded and extruded polystyrene (EPS and XPS) can live multiple lives — from protective packaging to high-performance insulation and now, decorative interior products.

This collaboration demonstrates that recycled polystyrene has far more potential than waste management alone. It can be reshaped, repurposed, and reimagined into materials that perform, protect, and beautify Australian homes.

The Power of Polystyrene Recycling in Australia

Each year, thousands of tonnes of expanded polystyrene packaging are used to protect appliances, electronics, and construction materials during transport. While EPS is lightweight and durable, it can occupy significant space in landfill if not recycled.

Through the StyroCycle network — an initiative supported by industry partners like Foamex — clean EPS packaging is collected from local councils, community recycling points, and manufacturer depots across Australia.

Instead of being hot-melted sent overseas which only causes MORE pollution, the material is recycled locally, creating new employment opportunities and reducing the carbon footprint associated with long-distance transport. The recycled EPS is then transformed into high-density pellets — the feedstock for Foamex’s Styroboard™ XPS products such as StyroTherm™.

Closing the Loop with Foamex Styroboard™ XPS

Foamex is Australia’s only manufacturer of extruded polystyrene (XPS) and produces Styroboard™ XPS sheets (branded StyroTherm) containing up to 90% recycled content. By reprocessing collected EPS waste, Foamex diverts thousands of cubic metres of material from landfill each year and gives it a second, more valuable life.

Styroboard™ XPS is a high-performance insulation material trusted by builders, engineers, and architects across the country for its superior thermal efficiency, compressive strength, and long-term durability.

Key features of Foamex Styroboard XPS:

✔ Australian-made and compliant with AS1366.4
✔ HCFC-free and produced without refrigerants
✔ High compressive strength and dimensional stability
✔ Low water absorption and long-term R-value retention
✔ Lightweight, easy to install, and fully recyclable

This environmentally responsible approach means that Foamex’s production process not only supports the circular economy but also reduces reliance on virgin raw materials.

From Insulation to Interior Design: The Cornice Store Connection

The sustainability journey doesn’t end with insulation. In a powerful demonstration of circular economy construction, The Cornice Store uses Foamex XPS boards – the only XPS made in Australia – as the base material for their decorative cornice products — a creative application that redefines what recycled materials can become.

Manufactured locally in Melbourne, The Cornice Store’s innovative process turns XPS sheet made from recycled EPS packaging waste, into lightweight, durable and stunning cornices that are easy to install and perfect for modern Australian homes. Their production is clean and fully circular, capturing 100% of XPS offcuts and returning it back to us at Foamex to recycle once again.

Through this process, packaging waste that once protected goods in transit is now enhancing interiors, providing a tangible example of recycled building materials in Australia creating both environmental and aesthetic value.

Local Manufacturing, Global Impact

Circular partnerships like that between Foamex, The Cornice Store, and StyroCycle are reshaping Australia’s approach to sustainability. By keeping production, recycling, and distribution local, these businesses are building a self-sustaining ecosystem that delivers measurable environmental, social, and economic benefits.

Environmental: Waste diversion, lower CO₂ emissions, and reduced import reliance.
Social: Job creation within recycling and manufacturing sectors.
Economic: Strengthening of local supply chains and promotion of Australian-made innovation.

This model reinforces that circular design is not a distant ideal — it’s a practical, scalable reality that starts at the community level and extends to national manufacturing.

Innovation Through Collaboration

At its core, this partnership is about redefining what’s possible with recycled materials. Foamex’s Styroboard™ XPS provides the strength, consistency, and environmental integrity that customers like The Cornice Store relies on to craft their products. In turn, their work demonstrates to designers, builders, and homeowners that sustainable materials can also deliver on aesthetics and performance.

Together, we’re proving that recycling polystyrene is about more than reducing waste — it’s about closing the loop, designing smarter, and using Australian ingenuity to lead the way in sustainable construction and design.

Frequently Asked Questions About Foamex XPS

Is Foamex XPS insulation made from recycled polystyrene?

Yes. Foamex Styroboard™ XPS can contain up to 90% recycled content, derived from clean EPS packaging collected through the StyroCycle network.

Why is local polystyrene recycling important?

Local recycling reduces transport emissions, supports Australian jobs, and ensures material stays within a closed loop — helping achieve a circular economy for construction materials.

How is XPS different from EPS?

EPS (expanded polystyrene) is lightweight foam used for packaging and insulation, while XPS (extruded polystyrene) is denser, moisture-resistant, and ideal for high-performance insulation and decorative applications.

What makes The Cornice Store’s products sustainable?

Their cornices are made from Foamex XPS, using recycled polystyrene and capturing 100% of offcuts for recycling & reprocessing — creating a zero-waste manufacturing process.

Is XPS a suitable material for cornice?

Yes. Modern interior cornice is purely a decorative element, and XPS offers an easy-to-install solution which is moisture resistant and crack resistant without compromising on quality. It is widely used across international markets.

About The Cornice Store:

The Cornice Store is a locally owned and operated manufacturer and retailer of lightweight decorative cornice, based in Melbourne. It has been serving the Australian trade and consumer markets since 2023.
