Finnish Concrete Giant to Cut Cement Use by Half with Carbon Mineralizing Technology
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: Finnish concrete producer Lakka will launch industrial-scale production of CO2-cured concrete in early 2026, reducing cement content by 20-50% while permanently mineralizing carbon dioxide into the material.
📈 One key stat: Concrete is responsible for 8% of global carbon emissions, with 90% coming from cement production, making this technology’s ability to cut cement use by up to half critically important for climate goals.
💬 One key quote: “This is a multimillion-euro investment for us. Our goal is that within the next couple of years, half of the production at our Joensuu plant will utilize CO2 treatment,” says Juho Hiltunen, CEO of Lakan Betoni.
1️⃣ The big picture: Finnish concrete producer Lakka is making a significant move toward sustainable construction by planning large-scale production of CO2-cured concrete at its Joensuu facility in early 2026. The innovative technology from Carbonaide injects carbon dioxide directly into concrete during curing, where it becomes permanently mineralized while reducing the amount of cement needed by 20-50%. This advancement addresses a major environmental challenge, as concrete production accounts for approximately 8% of global carbon emissions. For Lakka, Finland’s leading supplier of concrete items to hardware stores, this shift represents both an economic and environmental strategy.
2️⃣ Why is this good news: This advancement marks a substantial step in reducing the carbon footprint of one of the world’s most carbon-intensive building materials. By replacing significant amounts of cement with carbon dioxide that becomes permanently stored, the technology addresses emissions at two levels – cutting cement-related emissions while sequestering CO2. The innovation makes sustainable building materials more accessible to everyday consumers through Finland’s top supplier of concrete products to hardware stores. Carbonaide’s technology reaching commercial scale with Lakka creates an important reference case for international expansion, potentially transforming concrete production worldwide.
3️⃣ What’s next: Lakka aims to convert half of its Joensuu plant’s production to CO2-cured concrete within the next few years following the 2026 launch. Carbonaide plans to use this domestic implementation as a reference for international expansion of their technology. The partnership positions both companies to lead concrete decarbonization efforts across Northern Europe.
