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?
  1. First, and most importantly, we still only recommend products that we believe add value for you.

  2. When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.

  3. 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?
  1. When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.

  2. When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).

  3. 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 capture project in Denmark will remove 435,000 tons of CO2 annually from a waste-to-energy facility, significantly advancing Aarhus city’s goal of becoming carbon-neutral by 2030.
📈 One key stat: The carbon capture project will remove 435,000 tons of CO2 annually, making it Denmark’s largest municipal carbon capture initiative.
💬 One key quote: “By combining our plant engineering know-how with BASF’s chemical expertise, we are well-positioned to support sustainability in waste management,” said Klaus Bärnthaler, Vice President at ANDRITZ Clean Air Technologies.

1️⃣ The big picture: BASF and ANDRITZ have signed a licensing agreement to implement a major carbon capture system at a [waste-to-energy facility in Aarhus, Denmark](https://carbonherald.com/basf-and-andritz-to-capture-435000-tons-of-co2-from-danish-waste-plant). The project aims to capture approximately 435,000 tons of CO2 annually using BASF’s OASE® blue gas treatment technology, which is specifically designed to handle the complex impurities found in waste incineration flue gases. This collaboration combines ANDRITZ’s engineering capabilities with BASF’s chemical expertise to address emissions from municipal waste processing. The initiative represents a significant step toward helping Aarhus achieve its ambitious goal of becoming carbon-neutral by 2030.

2️⃣ Why is this good news: This carbon capture project tackles emissions at their source, preventing hundreds of thousands of tons of CO2 from entering the atmosphere each year. The approach transforms waste management facilities from pollution sources into part of the climate solution. The technology’s high efficiency and low energy consumption demonstrate how industrial processes can be decarbonized without excessive operational costs. By targeting municipal waste processing, the project addresses emissions from an essential public service that typically cannot be eliminated. When implemented, this will stand as Denmark’s largest municipal carbon capture effort, creating a replicable model for other cities.

3️⃣ What’s next: ANDRITZ is currently conducting pre-engineering work for the carbon capture plant. Full implementation depends on securing funding approval from the Danish CCS Fund, which supports large-scale decarbonization projects throughout Denmark. If approved, the project will become a cornerstone of Aarhus’s climate strategy and demonstrate the viability of municipal-scale carbon capture.
