After the MSC ELSA 3 sank, concerns about marine pollution were raised, when vast amounts of plastic nurdle pollution threatens the Thiruvananthapuram coast, and it is believed that the pellets, which were discovered in places including Vettukad, Thumba, and Kochu Veli, were from containers that washed up on the shore following the catastrophe. This tragedy highlights the growing concern about microplastic pollution to marine ecosystems and coastal communities, as it is the first major oil spill from a maritime disaster in India.

What Are Nurdles and Why Are They a Concern?

According to the International Organisation for Standardisation (ISO 472:2013), nurdles are tiny, pre-formed masses of molding material used as raw materials to make plastic goods, including fabrics, bottles, and packaging. They usually have a diameter of 1 to 5 millimeters. These primary microplastics, which are buoyant and frequently mimic fish eggs, are dangerous to marine life because they are mostly made of polyethylene, polypropylene, polystyrene, or polyvinyl chloride. Nurdles are not intrinsically harmful, but once they get into the water, their buoyancy and small size make them a hazardous contaminant, according to A Biju Kumar of the Department of Aquatic Biology and Fisheries at the University of Kerala.

Every year, millions of tonnes of nurdles are carried worldwide, and leaks have seriously harmed the environment. The 2017 Durban Port spill in South Africa and the 2012 Hong Kong spill during Typhoon Vicente are noteworthy events that severely damaged marine life and local economies reliant on tourism and fishing. Low-density polyethylene (LDPE) and high-density polyethylene (HDPE), used in plastic bags, bottles, and pipes, are the primary materials used in Thiruvananthapuram. Recycling LDPE, in particular, makes cleanup operations more difficult.

The Environmental Impact and Response

On May 25, 2025, the Liberian-flagged cargo ship MSC ELSA 3, which was carrying 640 containers, sank 38 nautical miles off the coast of Kerala. Its load included 367.1 metric tonnes of furnace oil, 84.44 metric tonnes of diesel, and 13 hazardous goods containers. Since then, about 100 containers containing textiles, tea, and nurdles have washed up on the strand. Because the pellets can cause intestinal obstructions and malnutrition in fish, turtles, and seabirds, they seriously threaten marine biodiversity. Additionally, harmful contaminants like PCBs and DDT are absorbed by newborns from salt water, which may then find their way into human diets and food chains.

Nurdles’ small size and propensity to mingle with sand make cleanup intimidating. Experts advise using floating booms, specialized sifting gear, and hand beach cleanups to confine and remove them. Better container packaging, quick reaction teams, and more stringent guidelines for spill reporting are examples of preventive measures. According to K V Thomas, the former head of the Marine Sciences Division at the National Centre for Earth Science Studies, “this incident highlights the risks of plastic waste in fragile ecosystems.” Plastic nurdle pollution threatens the Thiruvananthapuram coast, and the spill highlights the urgent need for international action to minimize plastic pollution and save marine life, as an estimated 230,000 tonnes of nurdles enter seas each year.
