Paebbl Rebond 300

We're excited to launch Rebond 300, the world’s first carbon-negative construction material with an EPD-verified footprint of -149 kg CO₂ per tonne. It marks the latest addition to our Rebond series of carbon-negative construction materials, representing a 10x improvement in net carbon performance compared to our first-generation product. Every tonne of material we produce now removes significantly more CO₂ from the atmosphere than is emitted during its entire production process.

What's New

• Improved carbon efficiency -149 kg CO₂eq per tonne, independently verified through our Environmental Product Declaration.
  
• Greater project-level impact. Up to 40% embodied carbon reduction at standard replacement ratios on the concrete level.
  
• Seamless integration. Rebond 300 works with existing ready-mix and precast workflows.
  
• A lighter finish. Rebond 300 has a light, fine-grained character that opens up architectural possibilities.

Rebond 300 is not an iteration on existing construction materials. It is a fundamentally different class of product.

Where conventional construction materials are optimised to reduce their carbon footprint, we’ve manufactured Rebond 300 to remove carbon from the atmosphere and lock it permanently into the built environment. Paebbl’s mineralisation process captures and locks away CO₂ in a stable mineral form that will remain sequestered for geological timescales, inside the structures we build today.This is what the next generation of construction materials looks like. Every building, every foundation that incorporates Rebond 300 becomes a permanent carbon sink, contributing to Scope 3 targets through the physical chemistry of the material itself.The construction industry has long been framed as one of the hardest sectors to decarbonise. Rebond 300 reframes that entirely. Real estate turns into the mechanism through which gigaton-scale carbon removal becomes possible, embedded invisibly into the infrastructure the world is already building.Performance and aesthetics with no trade-offs for the value chain

Rebond 300 can replace up to 30% of cement in concrete mixes without compromising structural performance. Its near-white finish opens applications across exposed concrete, architectural elements, and facade systems.

For architects and specifiers, this unlocks a new level of environmental and aesthetic design. They finally have a material that brings both the lowest verified embodied carbon on the market and the aesthetic range to match the ambition of their projects.

Every tonne of Paebbl Rebond 300 added to concrete mixes constitutes verified CO₂ removal, a permanent mineral sequestration embedded in the resulting concrete structure. That is a dual value proposition the market has not had before: a high-performance construction material that simultaneously functions as a carbon removal instrument, entering the value chain without requiring changes to equipment or production infrastructure.

The -149 kg CO₂/t footprint is the result of continuous process optimisation in our mineralisation technology. It is backed by a full EPD under recognised European standards. When our customers specify Rebond 300, the numbers hold up to scrutiny.

From material producers integrating a verified carbon-negative product into their portfolio, to RMX plants differentiating on embodied carbon, to contractors and developers who need Scope 3 performance that is real and reportable, we now want to build the reference cases that set the standard for this industry.
