The Construction Material That Removes 149kg of CO2 Per Tonne
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: A new carbon-negative construction material has been launched that removes more CO2 from the atmosphere than it emits during production, opening a path to decarbonize one of the world’s hardest-to-abate industries.
📈 One key stat: Each tonne of the new construction material carries a verified carbon footprint of -149 kg CO2, meaning it actively removes more carbon than its entire production process emits.
💬 One key quote: “Every structure that incorporates Rebond 300 becomes a permanent carbon store, contributing to Scope 3 targets through the physical chemistry of the material itself, not through accounting adjustments,” Paebbl explained.
1️⃣ The big picture: Construction is one of the most carbon-intensive industries on the planet, and finding ways to decarbonize it at scale has long been a major challenge. A Dutch startup has now launched a concrete additive called Rebond 300, verified to carry a carbon footprint of -149 kg CO2 per tonne, making it the first construction material of its kind to remove more carbon than it produces. The product works by converting captured CO2 into a stable mineral powder using a process called geomimicry, a form of accelerated mineralization. Builders can use it as a supplementary cementitious material to replace conventional cement types, and every structure built with it effectively becomes a permanent carbon storage site. The carbon footprint figure has been independently verified through an Environmental Product Declaration.
2️⃣ Why is this good news: For the first time, you can build with a material that actively pulls carbon out of the atmosphere rather than adding to it, turning infrastructure projects into long-term carbon sinks. Construction accounts for a massive share of global emissions, and a product that slots into existing concrete workflows while delivering negative carbon performance has the potential to shift the industry at scale. Because the CO2 gets locked into the mineral structure of the material itself, the storage is permanent rather than reliant on ongoing management or accounting offsets. Organizations looking to meet science-based climate targets can also purchase verified carbon dioxide removal credits generated through the use of this material. As projects grow bigger, their carbon storage impact grows with them, flipping the traditional logic of large-scale construction entirely.
3️⃣ What’s next: Paebbl is currently in discussions with partners across several sectors, including data centers, public infrastructure, coastal protection, and residential and retail buildings. The company has already successfully integrated earlier versions of its product into a range of cement and concrete constructions. Scaling these partnerships will be key to proving the material’s impact beyond pilot projects and into mainstream construction supply chains.
