A fungus capable of “eating plastic” and transforming it into far less harmful substances may sound like the plot of a science fiction film, but it is the subject of genuine scientific research. According to a report published by the Italian newspaper Quotidiano Nazionale, researchers are investigating a microorganism able to degrade specific plastic polymers through naturally occurring enzymes, potentially opening the door to new industrial recycling technologies.
Although scientists have been studying plastic-degrading microorganisms for several years, recent advances have renewed optimism that certain fungi and bacteria could eventually become valuable allies in tackling one of the world’s most pressing environmental challenges.

How Does the Plastic-Eating Fungus Work?
The biological process is surprisingly straightforward. The fungus produces specialised enzymes that attack the chemical structure of plastic, gradually breaking long polymer chains into much smaller molecules.
Laboratory experiments have shown promising results with materials such as PET, one of the world’s most widely used plastics for beverage bottles, food packaging and synthetic fibres. However, researchers emphasise that the technology is still in development. Current degradation rates remain too slow for large-scale commercial use, and scientists are working to improve the efficiency of these enzymes through biotechnology.
Why Plastic Pollution Remains a Global Emergency
Every year, the world produces hundreds of millions of tonnes of plastic, yet only a relatively small proportion is effectively recycled. Large quantities end up in landfills, are incinerated or leak into rivers and oceans, where they gradually break down into microplastics that contaminate ecosystems and even enter the human food chain.
International organisations continue to warn that existing recycling systems alone cannot cope with the volume of plastic waste generated worldwide. As a result, innovative solutions such as plastic-degrading fungi are attracting growing interest as potential additions to the broader circular economy, complementing mechanical recycling, chemical recycling and efforts to reduce plastic consumption.
How Europe Regulates Plastic Recycling
The European Union has introduced some of the world’s most ambitious legislation on plastic waste and recycling.
The Single-Use Plastics Directive (SUP) has banned or significantly restricted a wide range of disposable plastic products, while the Circular Economy Action Plan has established increasingly demanding recycling targets across Member States.
Among the most significant measures are:
- mandatory separate collection for most PET bottles
- minimum recycled-content requirements for new plastic beverage bottles
- extended producer responsibility, making manufacturers more accountable for waste management
- increased investment in advanced recycling technologies and innovative waste-treatment solutions
The EU’s long-term objective is to reduce plastic pollution while transforming waste into a valuable economic resource.
The United States Takes a Different Approach
Unlike Europe, the United States does not have a single nationwide regulatory framework governing plastic recycling. Instead, responsibility largely rests with individual states, resulting in considerable differences across the country.
States such as California have adopted ambitious recycling targets, minimum recycled-content requirements and stricter packaging regulations. Others have implemented more limited policies, creating a fragmented regulatory landscape.
At the same time, federal agencies and private companies are investing heavily in chemical recycling, biotechnology and next-generation waste management systems, recognising that biological innovations—including plastic-degrading fungi and enzymes—could become strategically important for both environmental protection and industrial competitiveness.
Can One Fungus Solve the Plastic Crisis?
Scientists remain cautious. While the fungus represents a highly promising technological breakthrough, it is far from being a miracle solution. Before it can be deployed on an industrial scale, researchers must demonstrate that it can process large quantities of plastic efficiently, safely and at a commercially viable cost.
Most experts believe that the future will depend on multiple complementary strategies: reducing single-use plastics, designing products that are easier to recycle, improving waste collection systems and developing new biological technologies capable of treating plastics that are currently difficult to recycle.
A Discovery That Could Shape the Future of Recycling
The growing interest in plastic-eating fungi highlights a broader reality: the challenge is not simply disposing of plastic, but fundamentally rethinking how we produce, consume and recover it.
If ongoing research confirms the encouraging laboratory results, these microorganisms could become an important tool in reducing the environmental impact of plastic waste. Until then, however, scientists and policymakers agree that the priority remains clear: producing less unnecessary plastic, improving recycling systems and accelerating the transition towards a truly circular economy.
