New Seashell-Based Material Could Replace Ocean-Harming Plastics
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: USC researchers have developed a biodegradable plastic alternative from seashell minerals and citric acid polymers that could replace traditional plastics and protect millions of marine species from pollution.
📈 One key stat: Plastics make up 80 percent of all ocean pollution, with an estimated 8 to 10 million metric tons entering the oceans each year, highlighting the urgent need for sustainable alternatives.
💬 One key quote: “The USC team is paving the way for a new era of environmentally friendly plastics.”
1️⃣ The big picture: Scientists at the University of Southern California have engineered a novel biodegradable plastic alternative using calcium carbonate from seashells combined with a citric acid polymer. Led by Eun Ji Chung, the team created a material called POC-CC that maintains the pH of ocean water while being fully biocompatible with marine microorganisms. This breakthrough addresses the critical issue of ocean pollution, where billions of plastic pieces harm marine ecosystems worldwide. The researchers have already created prototypes like beverage holder rings and are exploring additional applications such as biodegradable straws.
2️⃣ Why is this good news: This innovation offers a real solution to one of our most pressing environmental challenges – plastic pollution in oceans. Unlike conventional plastics, the POC-CC material doesn’t introduce harmful microplastics into marine ecosystems when it degrades. Extensive testing has confirmed the material’s compatibility with marine microorganisms like green algae, proving its safety for ocean environments. The team is already developing a second-generation version promising even faster degradation rates. Since the material uses FDA-approved components, it has potential for rapid commercialization across various consumer products.
3️⃣ What’s next: Researchers plan to expand testing of their ocean-safe material for various consumer applications beyond beverage holders, with biodegradable straws being a priority. The team is developing a second-generation version of POC-CC designed to degrade even faster in marine environments. Scientists will likely seek industry partnerships to scale production and bring these sustainable alternatives to commercial markets.
