Case Study: From waste to wow – verified low-carbon joinery

saveBOARD x Rebuilt – Circular Materials, Certified Impact

saveBOARD has been flipping the script on building materials for a while now. Their latest product, betterJOINERY, turns post-consumer soft plastics into sleek, durable boards for cabinetry and fitouts made almost entirely from waste that would otherwise end up in landfill.

saveBOARD had already carved out a reputation for bold design and circular thinking. But as market expectations shifted, especially among architects, certifiers, and government clients,they needed to go further. They needed to quantify the carbon footprint too.

It’s a bold sustainability innovation. But in a carbon-conscious market, being circular isn’t enough. Clients, governments and certifiers now also need verified carbon data, ready to meet compliance requirements and drive procurement.

“We know our products are low-carbon. But telling that story with verified data changes the conversation with customers.”
 — Paul Charteris, CEO, saveBOARD

How recycled content can drive down your embodied carbon profile

The numbers mattered. Material selection often makes up more than 50% of a product’s total emissions. Swapping virgin materials for recycled inputs can make a massive dent in a product’s carbon footprint — but only if it’s measurable, verifiable, and comparable.

And betterJOINERY delivers.

Compared to standard building boards like MDF and particleboard, betterJOINERY creates far less carbon pollution when it’s made. In fact, it cuts emissions by around 80% compared to typical MDF.

To put it simply:

• A square metre of MDF creates 10 kg of carbon emissions
• Particleboard creates 4.8 kg
• betterJOINERY? Just 1.5 kg

That’s a huge drop — just by using waste materials instead of virgin ones. And now, it’s all independently verified.

Rebuilt: Data That Keeps Up with Innovation

While SaveBOARD had previously worked with Environmental Product Declarations (EPDs), this time they were looking for a faster and more adaptive approach that could keep pace with their rapid innovation cycles and offer meaningful insights across their full product range.

That’s where Rebuilt came in.

Partnering with Rebuilt gave saveBOARD the flexibility and speed they were looking for. Together, they mapped emissions from end to end - from recycled feedstock sourcing through to production- and generated Product Carbon Footprints (PCFs) that was then verified by a Rebuilt Life Cycle Assessment (LCA)expert to ISO 14067.

“The EPDs we’d done before were a great grounding in the LCA process, but Rebuilt’s easy-to-use platform and management dashboards made it easier to manage and compare our whole product inventory and to scenario-plan new formulas and innovations to meet evolving customer needs.”
 — Paul Charteris

Rather than waiting months or years to update a static report, SaveBOARD can now assess new materials, explore the carbon impact of different formulations, and respond to market opportunities in real time - all with third-party verified, audit-ready data.

The Impact: Verified, Trusted, Market-Ready

With Rebuilt, SaveBOARD now has carbon data that matches their sustainability ambition, and their pace. Their boards show near-zero upfront carbon emissions, with over 90% reduction in virgin material inputs, backed by independent verification.

That data is now at their finger tips - ready for tenders, client conversations, certifications, and product development. It gives them a clear edge in carbon-conscious procurement and strengthens alignment with frameworks like Green Star and NABERS.

But the real value? Agility.

“Now we’re not just reporting - we’re using the data to guide business development and respond to client needs faster than ever.”
 — Paul Charteris

What it means for the Industry

SaveBOARD’s story isn’t just a win for one product - it’s a signal of where the industry is heading. Circularity remains vital, but verified carbon performance is becoming non-negotiable. The ability to adapt quickly and credibly is fast becoming a competitive advantage.

With Rebuilt, saveBOARD has unlocked the tools to innovate, lead, and grow - with data that keeps up.
