Plastic Eating Alage!
AI summary Read the abstract
Scientists engineered a strain of algae with special genes that can break down plastic into a harmless carbon compound, potentially tackling the 91% of plastic that never gets recycled and instead breaks down into microplastics polluting our water, food, and bodies. If this works as hoped, these plastic-munching algae could be released into waterways to clean up pollution before it fragments into the microplastics we're increasingly finding in human blood and organs—and could even be turned into biofuel as a bonus. This is early-stage lab research, so it's not yet a proven solution, but it's a promising step toward reducing plastic pollution at its source.
Did you know that only about 9% of all plastics ever get recycled? (Houssini et al., 2025) This leaves a concerning 91% that is stored in landfills or the environment as pollutants, continuously diffusing into microplastics. Plastic components can be found in nearly every product on our shelves. This, combined with the conditions of the global economy, has led to the mass production of substances that can never truly be broken down. To curb this inescapable pollution, our team at the JCCC cell biology lab is working to create a strain of Chlorella vulgaris (algae) that can break down and convert polyethylene terephthalate (plastic) into ethylene glycol (an organic carbon molecule) via PETase and MHETase enzymes. To do this, we altered the DNA of wild-type Chlorella vulgaris by adding a gene using Agrobacterium and electroporation. We then selected and screened clones using hygromycin B (antibiotic indicator) to ensure we had positive clones, confirmed by extracting and analyzing DNA for the presence of PETase and MHETase genes. We introduced wild-type controls and positive clones to plastic samples and measured mass before and after several weeks to test effectiveness. If successful, the implications of this research are incredibly profound. New strains could be introduced into waterways, which would naturally reduce plastic pollution in them while also preventing plastic from taking up space in landfills or inevitably diffusing into microplastics. Algae are also considered candidates for biofuels, so the possibility of "feeding" algae with our plastic waste to produce clean energy is incredible.

Plastic Pollution Degradation Experiment
AI summary Read the abstract
Scientists are trying to engineer algae that can "eat" plastic waste, which could one day help shrink the mountains of plastic polluting our oceans and land—plastic that eventually breaks down into microplastics found in our food, water, and even our bodies. So far, the team successfully modified algae cells but hasn't yet confirmed the plastic-degrading gene took hold, so this is an early, unproven step rather than a working solution. It's a hopeful idea worth watching, but there's no evidence yet that it actually reduces plastic pollution.
Engineered Algae for Plastic Degradation
AI summary Read the abstract
Scientists genetically modified a type of algae to produce two enzymes that can break down common plastic waste, successfully creating and verifying a strain that carries this plastic-eating ability. While this is still an early-stage proof of concept, it points toward a future where engineered algae could help clean up plastic pollution in oceans and waterways — which matters because plastic breaks down into microplastics that are increasingly found in our food, water, and even our bodies.
Plastic-Eating Algae
AI summary Read the abstract
Scientists successfully engineered algae to carry genes from plastic-eating bacteria, creating tiny organisms with the potential to break down plastic waste. While this early-stage lab work still needs testing to confirm it actually degrades plastic effectively at scale, it points toward a promising future tool for tackling plastic pollution—which matters for human health since plastic waste breaks down into microplastics that end up in our water, food, and even our bodies.
Algae vs Plastic

Scientists genetically modified a common type of algae to produce enzymes that can break down plastic bottles, successfully confirming the algae took up the plastic-degrading genes. They're now testing how well this algae actually eats away at real plastic. If it works, this algae could one day be used to clean up plastic pollution directly in rivers and oceans, potentially reducing the microplastics that end up in our water, food, and bodies.
Plastic Eating Algae Project
AI summary Read the abstract
Scientists engineered algae to carry genes for plastic-eating enzymes, successfully creating algae clones that break down plastic. This matters because plastic pollution doesn't just harm wildlife—it breaks down into microplastics that end up in our water, food, and eventually our bodies, so finding ways to clean up plastic waste could reduce our long-term exposure. While this research is still early-stage, it points toward a promising, low-cost tool for tackling plastic pollution at its source.
