Plastic turned into food
Promising solution from natural ingenuity.
Plastic, with all its revolutionary properties and applications, is at the same time one of the biggest challenges for the environment, as less than 10 percent of it is recycled. But what if we could turn this ecological nemesis into food?
Beyond the idea of consuming plastic, there is an innovative approach: having other animals that can decompose it eat it. Recently, scientists have presented revolutionary results on the combination of insects and gut bacteria that can thrive by feeding exclusively on plastic.
Plastic, a name that encompasses several types of polymers, is extremely difficult to recycle because of its many components and additives. Modern separation techniques are insufficient, as recycled plastic cannot reproduce exactly the same material as its virgin predecessors, exhibiting inferior qualities and damage due to the melting process.
However, researchers are exploring a different angle: getting mealworms, larvae of the black soldier fly and other insects to digest the plastic. Some of these organisms, thanks to their microbiome, are able to thrive and adapt to a plastic-rich diet, a surprising prospect given the complexity of plastic's molecular structure.
The heart of this innovation lies in the ability of these animals to adapt to and derive nourishment from plastic, thanks to the incredible diversity of bacteria in their gut, distinct from those of other insects on a standard diet.
While plastic remains a difficult material for most animals to digest, the promising research on worms and larvae is a significant step toward a sustainable solution.
These small, hungry, growing organisms could be a pathway toward reducing plastic in the environment. However, many questions remain: how much do the results obtained vary and how much can we control this process to achieve the desired effects?
Despite the challenges, the idea of turning plastic into insect food is an example of natural ingenuity and adaptability, a clear sign of how nature itself can offer innovative solutions. This pioneering research represents a step forward in the race toward a cleaner, more sustainable environment.
