Styrofoam, also referred to as polystyrene, is a plastic that is frequently used in industrial, electronic, and food packaging. It is durable because it is hard to break down. Conventional recycling techniques, such as heat and chemical processing, can produce pollutants and are costly. We sought to investigate biological approaches to controlling this persistent waste because of this, among other reasons. The Kenyan lesser mealworm larvae can chew through polystyrene and contain bacteria in their intestines that aid in the material's breakdown, according to research I'm working on with a group of scientists from the International Centre of Insect Physiology and Ecology.
Although they are present in many nations worldwide, smaller mealworms are believed to have originated in Africa. However, the species we found in our investigation might be a subspecies of the genus Alphitobius. To verify this possibility, we're looking into it more. We also looked at the bacteria in the insect's intestines. Finding the bacterial communities that might aid in the breakdown of plastic was our goal. Some African nations have extremely high levels of plastic pollution. Africa presents a unique difficulty because of the significant importation of plastic products, limited re-use, and lack of recycling of these products, despite the fact that plastic waste is a serious environmental issue worldwide.
We intend to develop new instruments that aid in the quicker and more effective disposal of plastic waste by researching these naturally occurring "plastic-eaters." We may employ the microorganisms and enzymes that these insects produce in factories, landfills, and cleanup sites in place of releasing a large number of them into garbage sites, which is impractical. This implies that there is a solution to address plastic trash that is simpler to handle on a broad scale.
Key finding
We conducted a trial that lasted more than a month. The larvae were fed a combination of polystyrene and bran, bran (a nutrient-dense diet), or polystyrene alone. Compared to mealworms fed only polystyrene, we discovered that those fed a polystyrene-bran diet had greater survival rates. Additionally, we discovered that they were more efficient polystyrene consumers than those on a diet consisting solely of polystyrene. This demonstrates the advantages of making sure the insects continued to eat a diet high in nutrients.
Although the mealworms' survival was aided by their diet of only polystyrene, they lacked the nutrients necessary to effectively break down polystyrene. This discovery reaffirmed how crucial a varied diet is for the insects to eat and break down plastic as efficiently as possible. Since polystyrene is mostly composed of carbon and hydrogen, the insects may be using it as a source of energy. About 11.7% of the total po was broken down by the mealworms fed a diet of plastic and bran.

Fathiya Khamis, International Centre of Insect Physiology and Ecology One intriguing new finding in the fight against plastic pollution is that mealworm larvae can eat polystyrene. Despite being the first African-native bug species to demonstrate this ability, they are part of a small group of insects that have been demonstrated to have the capacity to decompose
What's next
Some insect species have already shown that they can eat plastics, including superworms (Zophobas morio) and yellow mealworms (Tenebrio molitor). They have microorganisms in their stomachs that help them break down things like polystyrene. Our study is distinctive since it focuses on African native insect species that haven't been thoroughly examined in relation to plastic degradation. Because African insects and environmental conditions may differ from those in other areas of the world, this regional focus is crucial because it may provide fresh perspectives and workable solutions for the problem of plastic pollution in African contexts.Some insect species have already shown that they can eat plastics, including superworms (Zophobas morio) and yellow mealworms (Tenebrio molitor).

Given that it can eat polystyrene, the Kenyan lesser mealworm may be able to help reduce trash naturally, particularly for plastics that are difficult to recycle using traditional techniques. Future research might concentrate on separating and identifying the particular bacterial strains that break down polystyrene and looking at their enzymes. Our goal is to determine whether the enzymes can be mass-produced for trash recycling. To evaluate the adaptability of this insect for wider waste management applications, we might also investigate different kinds of plastics.
Strategies for maintaining insect health throughout extended plastic consumption and assessing the safety of the resulting insect biomass for animal feeds would also be necessary if the use of smaller mealworms for plastic decomposition were to be scaled up.The Discussion Senior Scientist at the International Centre of Insect Physiology and Ecology, Fathiya Khamis The Conversation has republished this article under a Creative Commons license.
