Tree-Shaped Microalgae Unit Removes CO2 Equivalent to 38 Trees in Georgia
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 microalgae-powered carbon dioxide removal unit shaped like a tree has been installed at Southwire’s Georgia facility, capable of capturing as much CO2 as 38 mature trees.
📈 One key stat: The microalgae unit has the atmospheric CO2 capture capacity equivalent to 38 fully grown trees, making it an efficient use of space for carbon removal.
💬 One key quote: “Our tree-shaped sculptures actively remove carbon dioxide from the atmosphere while engaging with the public and making a statement of beauty,” explained Algae Tree founder Jeffery Whitmire.

1️⃣ The big picture: Southwire and Algae Tree have successfully deployed an innovative carbon dioxide removal unit at Southwire’s Thorn Customer Solutions Center in Georgia. The installation, designed in the shape of a tree, uses Arthrospira platensis (spirulina) microalgae to capture CO2 from the atmosphere. This pilot project follows a prototype presentation by University of Georgia students at the 2024 Capstone Design Showcase event. The collaboration also includes UGA engineering students who will monitor the unit’s performance to gather data for future optimizations and larger-scale deployments.
2️⃣ Why is this good news: This aesthetic carbon capture solution combines functionality with visual appeal, making sustainability efforts more engaging to the public. The microalgae unit packs the carbon-capturing power of dozens of trees into a much smaller footprint, offering an efficient option for urban or space-limited environments. The involvement of university students creates valuable educational opportunities while advancing clean technology research. Data collected from this pilot installation will help optimize future deployments, potentially scaling this solution to make a meaningful impact on atmospheric carbon levels.
3️⃣ What’s next: University of Georgia engineering students will analyze performance data from the pilot installation to identify optimization opportunities. The insights gained will inform the design of future Algae Tree ventures aimed at larger-scale deployment. This collaboration between industry and academia establishes a framework for developing and improving this carbon removal technology.
