What if the issue isn’t the material itself, but the system wrapped around it?

In this conversation, we jump straight into the uncomfortable truth that there are no sustainable materials – only better choices made in context. Joining us is designer and Halo co-founder Sarah de Silva, as we unpack how coatings, building codes, logistics, incentives and infrastructure can quickly turn a ‘green’ option into a risky one. We explore how designers and decision-makers can find their way back to integrity, through clear end-of-life thinking, transparency and honest trade-offs.

We move beyond slogans and into what actually works. Think material passports that track what things are made of and where they’ve been. Think facade-as-a-service and take-back models that plan for recovery from day one. Think internal marketplaces that keep fit-out and retail materials circulating rather than sending them to landfill. We dig into why paper-versus-plastic isn’t a morality tale, when mono-material PET can outperform fibre, and why local infrastructure often decides the real-world outcome.

Place matters, and Australia has a rare opportunity right now. We talk bioregional manufacturing, smarter import standards, and pairing Indigenous knowledge with processing close to feedstocks. From fast-growing kelp to hemp, we highlight materials with outsized potential when paired with circular systems, and get real about what actually drives change within organisations: risk, talent and resilience.

If you’re working in circular design, packaging, architecture or supply chains, this conversation offers a grounded path from theory to practice. Give it a listen, share it with someone who writes specs, and tell us the one barrier you’d love to see removed next.
