Davide Zampini recently presented at the EnviroTech Conference and Exhibition in London – here is his LinkedIn summary from the event:

“What if CO2 is not only something we reduce, but something we can use?
That’s exactly what we explored at EnviroTech Conference and Exhibition London 2026 last week – a simple but important shift in perspective.

At Cemex Global R&D, we are working on converting CO2 directly from Cement kiln flue gases into carbon nano-materials – turning an emission into a valuable material stream.

What this project has shown us is clear: CO2 is not just a challenge, it is a resource.
Taken directly from flue gases, we can convert it into carbon black, graphene, carbon nano-fibres and carbon nanotubes – with conversion efficiencies reaching up to 90%.

What started as a laboratory idea is now operating at industrial pilot scale – a WORLD FIRST at this level, enabled by a novel process and a novel catalyst.  Even more interesting, the process can be tuned – allowing us to control the type and properties of the nano-materials produced.

For me, this reflects a broader shift – from managing carbon to engineering it into value, creating new and economically attractive pathways to reduce, and potentially eliminate, emissions from clinker production.”
