💚 From Coffee Waste to Stronger Buildings ☕
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.
Stay impactful,
Happy Friday 👋
Did you know your morning coffee could help build stronger cities?
Scientists found a way to turn used coffee grounds into a material that makes concrete up to 30% tougher…
It’s a win for both construction and the planet, turning waste into something solid. Literally!

Here are the impactful insights that I have for you today:
- How coffee grounds make concrete 30% stronger and reduce waste ☕
- The global task force that pushes for trillion-dollar climate finance reform 🌍
- How repurposed undersea cables help save endangered orcas 🐋
- Discussion of the week: sustainable fashion 💬
- And more… 💚

☕ Coffee Grounds Make Concrete 30% Stronger While Tackling Waste Crisis
1️⃣ The big picture: Australian scientists have discovered a remarkable way to repurpose coffee ground waste by turning it into a concrete-strengthening material. By heating coffee grounds to over 350°C without oxygen, they created a carbon-rich biochar that can make concrete up to 30% stronger. This innovation tackles two environmental challenges simultaneously – the massive disposal of coffee waste (about 10 billion kilograms annually) that releases greenhouse gases in landfills, and the environmentally damaging extraction of sand for concrete production. The process demonstrates how circular economy principles can create value from waste while conserving natural resources.
2️⃣ Why is this good news: This innovation turns a widespread waste problem into a valuable resource for the construction industry. The 10 billion kilograms of coffee grounds produced annually now have potential use beyond landfills where they would emit harmful greenhouse gases. The technique helps preserve natural sand resources by providing an alternative strengthening component for concrete. By applying circular economy principles, this technology reduces environmental impact on multiple fronts – less waste in landfills, fewer emissions, and reduced sand mining damage. The research connects Indigenous perspectives of sustainability with modern engineering to create truly sustainable materials.
3️⃣ What’s next: Researchers need to complete thorough testing of their coffee-enhanced concrete for long-term durability, including resistance to freeze/thaw cycles, water absorption, and abrasion. The team is also exploring creating similar biochar products from other organic waste sources like wood, food waste, and agricultural byproducts. Commercial scale-up will require additional testing and industry partnerships.

📢 Three More Good News
🌍 Global Task Force Pushes for Trillion-Dollar Climate Finance Reform at World Bank and IMF:
- 📰 The quick summary: Global economists urge the World Bank and IMF to overhaul their lending frameworks to help developing nations transition from fossil fuels and build climate resilience, potentially unlocking trillions in much-needed climate finance.
- 📈 One key stat: Developing countries (excluding China) will need up to $2.5 trillion annually by 2030 for clean energy, adaptation and loss and damage funds, highlighting the massive financial gap in addressing climate challenges.
- 💬 One key quote: “The big economic challenge right now is that capital flows are going in the opposite direction. They’re going from South to North,” Kevin Gallagher, director of Boston University’s Global Development Policy Center and a leading member of the task force that produced the report, said in an interview with Inside Climate News.
🐋 Undersea Internet Cables Repurposed to Save Endangered Orcas:
- 📰 The quick summary: Underwater fiber-optic cables are being tested in the Salish Sea as continuous microphones that can monitor endangered orcas, potentially creating a vast ocean monitoring network that provides real-time data on marine mammals.-
- 📈 One key stat: The world’s 870,000 miles of existing undersea cables could be transformed into a comprehensive marine monitoring system, dramatically expanding our ability to protect ocean wildlife.
- 💬 One key quote: “It transforms cables into continuous underwater microphones that can pinpoint whale locations and track their movements.”
🌸 Rare Underground Orchid Gets Lifeline as Scientists Perfect Conservation Methods:
- 📰 The quick summary: Scientists are working to conserve the rare underground orchid Rhizanthella that lives its entire life below soil, helping preserve one of the world’s most unique plant species that’s threatened by habitat loss and climate change.
- 📈 One key stat: Five species of Rhizanthella exist worldwide, making them among the rarest orchids on Earth and highly vulnerable to extinction.
- 💬 One key quote: “Rhizanthella is an extraordinary orchid that lives its entire life underground. It flowers below ground, has no leaves and survives by feeding on nutrients from a fungus that gets its food from the soil and by connecting with roots of the broom bush, Melaleuca uncinata.”
