Plastic pellets called nurdles are catching the attention of researchers and environmentalists. These small beads, a few millimeters in size, used in the manufacture of many plastic products, have recently been reported in the North Sea following a maritime collision. The presence of these pellets raises growing concerns about marine pollution and its impact on ecosystems. Nurdles, often invisible to the naked eye, continue to pose a major challenge to the health of the oceans and the wildlife that inhabits them.

What are nurdles?

Nurdles are pre-production plastic pellets, serving as raw material to manufacture a multitude of plastic products we use daily. Their size is similar to that of a lentil, and their environmental impact is considerable. Every year, billions of nurdles end up in the oceans, often as a result of transportation accidents or accidental spills during manufacturing. This phenomenon is particularly alarming because these small pellets can be mistaken for food by seabirds, leading to fatal consequences for marine wildlife.

The consequences of a maritime collision

Recently, a maritime collision in the North Sea brought the issue of nurdles to light. This type of spill is part of unfortunate events that occasionally occur, causing increased pollution of the waters. Once in the water, nurdles can break down into nanoparticles, making their cleanup nearly impossible. These particles float for decades and have harmful effects on marine ecosystems, disrupting food chains and contaminating marine species. Moreover, their presence is increasing in light of the regulatory limits around these micropollutants.

A major environmental issue

Nurdles represent one of the main sources of micropollutants in the oceans, right behind tire debris. Countries have not yet officially recognized nurdles as hazardous waste, despite their catastrophic environmental impact. This lack of classification hinders cleanup efforts and spill prevention. Pellets can also ingest toxins, which then enter the bodies of marine wildlife, creating a threat not only to the environment but also to the ecological harmony of the oceans.
