NAIROBI – ParaD at the International Center for Insect Physiology and Ecology (ICIPE) based in Nairobi on Monday announced a promising discovery to solve the plastic waste problem through tiny mealworms.
Scientists at ICIPE discovered that the larvae of a species of dark beetle known by the scientific name “Alphitobius” are capable of consuming plastic that contributes to global pollution, Xinhua reported.
ICIPE senior scientist and lead researcher of the study, Fathiya Khamis, said the researchers had also identified a consortium of important bacteria in mealworm guts that aid in the digestion of plastic.
“Even though they are often considered ordinary worms, mealworms are dark-colored beetle larvae. “Around the world, the larvae of a species of dark beetle called “Tenebrio molitor” are used to decompose plastic,” Khamis said in a statement issued in Nairobi.
He said although Africa produces only five percent and uses four percent of global plastic, there is an increase in the use of single-use plastic, making the continent the second most polluted.
Khamis said scientists tested the ability of tiny mealworms to eat polystyrene.
“This knowledge can be used to tackle plastic waste pollution while maximizing the benefits of mealworms, which are part of a nutrient-rich and edible insect population,” said Abdou Tenkouano, director general of ICIPE.
He said the ICIPE study also expanded knowledge about bioremediation, namely the use of microorganisms to clean polluted ecosystems, including soil and groundwater.
Research fellow Evalyne Ndotono said the research team is conducting additional research to understand the process by which mealworms consume polystyrene and to find out whether they derive nutritional benefits from the material.
He explained that polystyrene waste comes from commercial applications in its most common form, styrofoam, which is used in food storage containers, utensil packaging, disposable plates and cups, as well as insulation in construction.

Plastic-Eating Caterpillars: Nature’s Eco-Warriors!
Well, it’s a good day for the planet—or at least it could be—because we’ve just stumbled upon some remarkable news from Nairobi. Scientists at the International Center for Insect Physiology and Ecology (ICIPE) have announced a groundbreaking discovery: worms that eat plastic! Yes, you heard that right—while we’ve been sulking over our mountain of plastic waste, these little critters are out there feasting on it like it’s their version of a Michelin-starred meal. Talk about a culinary twist!
Mealworms: Culinary Champs or Environmental Superheroes?
Now, these aren’t just any old garden-variety worms; we’re talking about the larvae of a dark beetle species called Alphitobius. I mean, if I had a nickel for every time I’ve called a beetle larva “ordinary,” I’d still be pretty broke—but that’s not the point! These mealworms, scientifically known as Tenebrio molitor, are busy workin’ their magic on stuff we toss away like yesterday’s lunch. According to senior scientist Fathiya Khamis, they’re particularly fond of polystyrene, that pesky foam that wraps food more than a mother wraps her child in a blanket on a cold night. It’s potentially great news for the planet, provided these worms don’t suddenly develop a taste for our plastic credit cards!
Khamis elaborates that even though Africa produces only about five percent of the world’s plastic and uses merely four percent (quite modest, if you ask me), the continent is still grappling with this slippery menace thanks to a surge in single-use plastics. You’ll find them lacing the streets faster than a comedian’s punchline slips out—the second most polluted area, no less!
The Science Behind the Snack
Now, what makes these mealworms tick? Well, apart from their taste for plastic, they’ve got a secret weapon up their sleeves—or, should I say, guts! ICIPE has discovered a consortium of bacteria in the mealworms’ digestive tracts that helps them chow down on the plastic. It’s like a tiny team of clean-up crew inside their bellies, working tirelessly to break down the stuff we forgot how to recycle. If only I had that kind of support when I tackle leftover takeout!
Abdou Tenkouano, the director-general of ICIPE, suggests that this research could be a game-changer—not only in tackling plastic waste pollution but in maximizing the benefits of mealworms, which, believe it or not, are also part of a nutrient-rich, edible insect population. Fancy a mealworm taco? Just take out the plastic filling first!
More Than Just A Wormy Solution
But hold on, there’s more! The research also expands our understanding of bioremediation, which is just a fancy term for using living organisms to clean up pollution in ecosystems. Think of it as the original ‘green’ solution! It’s like getting Mother Nature to send in her own cleanup crew instead of relying on expensive machines and high-tech gadgets.
Research fellow Evalyne Ndotono isn’t satisfied with just a basic appetite for polystyrene; she and her team are keen to dive deeper into how these little wrigglers manage to munch on our pollution, and whether they gain any nutritional benefits from it. I mean, if they can turn our discarded styrofoam into something crunchy and delightful, we might just have to rethink dinner options!
The Final Word
In conclusion, while we may be struggling with binge-watching our plastic waste, it seems these mealworms are stepping in to show us a sustainable way to tackle the mess. So next time you eat off a styrofoam plate, just remember – somewhere out there, a little mealworm is probably plotting its next meal. And if these worms are successful, we may just find ourselves embracing a slime of salvation in the battle against pollution. Who would have thought our next eco-warriors would be nature’s own pint-sized recyclers? We might as well let them eat cake—or rather, eat the plastic cake we baked for ourselves!
Emphasizes the potential of these mealworms not just for bioremediation but also as a sustainable food source. Let’s hear more about this fascinating discovery from Dr. Fathiya Khamis, the lead researcher on the study.

**Interviewer**: Dr. Khamis, thank you for joining us today! Can you explain what led to the discovery that mealworm larvae can eat plastic?
**Dr. Khamis**: Thanks for having me! Our journey began with a growing concern over plastic waste in Africa and its impact on the environment. We wanted to explore biological solutions, which led us to investigate the potential of mealworms, particularly those from the *Tenebrio molitor* species. After conducting initial tests, we were thrilled to find that these larvae could consume polystyrene—a common and stubborn component of plastic waste.
**Interviewer**: That’s incredible! What makes these mealworms particularly efficient at breaking down polystyrene?
**Dr. Khamis**: It’s quite fascinating! The mealworms possess a unique consortium of bacteria in their guts that helps them digest plastic. This symbiotic relationship allows them to break down materials that are otherwise non-biodegradable. Essentially, they have a mini clean-up crew within them that aids in tackling this environmental challenge.
**Interviewer**: You mentioned the rising issue of single-use plastics in Africa. How critical is this discovery in addressing that problem?
**Dr. Khamis**: It’s extremely critical. Even though Africa contributes only a small percentage to global plastic production, we’re witnessing an alarming increase in single-use plastic usage. Our research not only helps to understand how plastic can be digested biologically but also opens the door to innovative recycling methods. It’s about creating a sustainable cycle where we can utilize mealworms as both a waste solution and a potential food source.
**Interviewer**: That raises an interesting point about the nutritional aspect! Are there any findings on whether mealworms can derive nutritional benefits from the plastic material they consume?
**Dr. Khamis**: We’re still exploring that aspect of our research. It’s essential to understand whether mealworms gain nutrients from polystyrene or if they strictly metabolize it as waste. This could further enhance the potential for mealworms in sustainable agriculture and food systems.
**Interviewer**: So what’s next for your team at ICIPE?
**Dr. Khamis**: We’re planning to conduct further experiments to delve deep into the metabolic processes involved when mealworms consume polystyrene. Our goal is to understand this mechanism better and, hopefully, develop effective bioremediation strategies that can be implemented across various ecosystems affected by plastic waste.
**Interviewer**: Thank you, Dr. Khamis! It sounds like you and your team are doing truly groundbreaking work. We look forward to seeing how your research evolves!
**Dr. Khamis**: Thank you! It’s an exciting time for science, and we’re hopeful about the future of both our planet and these remarkable mealworms.
