Groundbreaking Construction Material Unveiled
On June 30 at 8:45 PM, the company Paebbl announced the creation of the world’s first building material that permanently locks away CO2. This innovative material, named Rebond 300, is a supplementary cementitious material (SCM) capable of replacing up to 30% of Portland cement in standard concrete mixes. According to its Environmental Product Declaration (EPD), Rebond 300 boasts a carbon footprint of -149 kg CO2 per ton, confirming its environmental performance.
How It Works and Where It’s Used
The technology behind Rebond 300 relies on an accelerated mineralization process that compresses natural geological cycles into a controlled manufacturing timeframe. The result is a fine, light-gray mineral powder that can be seamlessly integrated into existing precast and ready-mix concrete production lines without requiring new equipment. At standard replacement rates, this material can cut the total embodied carbon of a concrete structure by up to 40%.
Rebond 300 has an almost white appearance and is already being used in industrial applications. Earlier this year, Paebbl poured a 420 m² industrial floor slab for a global retailer’s logistics center in Germany. Notably, Paebbl is collaborating with European industry giants such as Holcim and Heijmans, underscoring the material’s market recognition and potential.
'While conventional building materials are optimized to reduce their carbon footprint, we engineered Rebond 300 to remove carbon from the atmosphere and lock it into buildings forever,' stated representatives from Paebbl.
The adoption of Rebond 300 could fundamentally transform construction and concrete production practices, as this material not only reduces CO2 emissions but actively absorbs them. This may represent a major step in combating climate change and accelerating the shift toward more sustainable building methods. Through partnerships with leading industry players like Holcim and Heijmans, Paebbl has the potential to influence construction standards across Europe and beyond, with far-reaching implications for the environment and sustainable development.
In addition to the advancements made with Rebond 300, recent research has shown that injecting CO2 can enhance concrete strength by 13%. This finding highlights the potential for integrating carbon capture technologies in construction, further pushing the boundaries of sustainable building practices.
