New Method Turns Toxic PFAS into Graphene and Fluoride Salts
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 technology can safely destroy harmful forever chemicals while turning them into valuable graphene, offering an effective solution for widespread PFAS contamination.
📈 One key stat: The new method removed 99.98 percent of one of the most common forever chemicals from contaminated materials, demonstrating its exceptional effectiveness in PFAS cleanup.
💬 One key quote: “Our method doesn’t just destroy these hazardous chemicals; it turns waste into something of value,” says chemist James Tour from Rice University.
1️⃣ The big picture: Scientists have developed a breakthrough method to tackle the growing problem of PFAS (per- and polyfluoroalkyl substances) contamination. These ‘forever chemicals’ are found nearly everywhere on Earth and are linked to various health issues. The new technique, using extreme heat exceeding 3,000°C to break down PFAS captured in granular activated carbon, not only destroys the harmful chemicals but also converts them into useful materials like graphene and fluoride salts, making it both environmentally and economically beneficial.
2️⃣ Why is this good news: This innovative approach solves multiple environmental challenges simultaneously. By destroying harmful forever chemicals while creating valuable materials like graphene, the process makes PFAS cleanup more economically viable. The method is quick, energy-efficient, and cheaper than existing removal processes. The technology can potentially be scaled up for wider use and adapted for different types of forever chemicals. This advances our ability to clean up widespread PFAS contamination while reducing waste and creating useful resources.
3️⃣ What’s next: Researchers aim to scale up this technology for broader industrial use. The team plans to adapt the method for treating other types of forever chemicals beyond the ones tested. The cost-effective and environmentally friendly nature of the process makes it promising for widespread implementation in water treatment facilities and environmental cleanup operations.
