Plastic Nurdles from sunk container ship off Kochi coast wash ashore in TN, raising alarm for Gulf of Mannar
Environmental concerns are mounting following the sinking of the container ship MSC ELSA 3 off the coast of Kerala, as plastic nurdles — tiny pre-production plastic pellets — have begun washing ashore in Tamil Nadu's Kanniyakumari district and are posing a threat for the eco-sensitive Gulf of Mannar.
The Liberia-flagged vessel sank on May 25, approximately 38 nautical miles off the coast between Vizhinjam and Kochi.
It was carrying 640 containers, including 13 classified as hazardous, along with substantial quantities of diesel and furnace oil.
The incident has led to a widespread dispersion of cargo, including plastic pellets, in the Arabian Sea.
In a worrying development, large quantities of nurdles packed in 25-kg bags began washing up on Kanyakumari beaches by Wednesday afternoon.
These pellets had already been reported on the shores of Thiruvananthapuram earlier this week.
Authorities believe prevailing ocean currents are pushing the spill southward, with the potential to impact the ecologically fragile Gulf of Mannar on the east coast.
The Gulf of Mannar is a critical marine biosphere reserve, home to coral reefs, seagrass meadows, dugongs, and sea turtles.
Experts warn that if the nurdles continue to drift eastward, the damage to this sensitive ecosystem could be severe.
Plastic nurdles are not inherently toxic but pose serious environmental threats.
Due to their small size and resemblance to fish eggs, they are easily consumed by marine animals, leading to internal blockages, malnutrition, and death.
Nurdles also absorb toxic pollutants from seawater, which can then enter the marine food chain and potentially affect human health.
Unlike oil spills, which can often be contained and cleaned, nurdles are buoyant and highly mobile. Once dispersed by tides and wind, they are virtually impossible to recover, making clean-up operations extremely challenging.
Officials from the Tamil Nadu State Disaster Management Authority, the Department of Environment, and the Tamil Nadu Pollution Control Board are working with local authorities to formulate an emergency response plan.
Meanwhile, a fact-finding committee formed by the Union Environment Ministry convened in Thiruvananthapuram on Wednesday to assess the situation.
This marks India's first major plastic nurdle spill caused by a shipwreck.
A similar incident in May 2021 off Sri Lanka's west coast released 1,680 tonnes of plastic pellets into the sea, but ocean currents at the time spared the Gulf of Mannar from contamination.

Tonnes of waste cleared daily, but GCC merely dumps it at shut sites?
1 2 Chennai: Chennai clears its streets of construction waste every day — but where does it all go? Nowhere, says the Tamil Nadu Pollution Control Board (TNPCB), in a detailed report submitted to the National Green Tribunal. Despite the Greater Chennai Corporation (GCC) collecting nearly 1,000 metric tonnes of construction and demolition (C&D) waste daily, the two official processing sites — Perungudi and Kodungaiyur — remain shut, with waste continuing to pile up since their closure. Perungudi stopped functioning in August 2024, while Kodungaiyur followed in December. Though both plants were set up in 2020 with a capacity of 400 MT per day and had valid consents to operate until 2030, the shutdown rendered the collection exercise incomplete. The collected debris is now accumulating at these very sites, violating environmental norms and threatening to undo efforts made under the Construction and Demolition Waste Management Rules, 2016. The TNPCB report also notes that GCC identified 25 dumping hotspots across the city, with persistent illegal dumping near parks, metro rail stations, and even crematoria. While GCC claims to have outsourced C&D collection and transportation to a private contractor, the TNPCB inspections across all 15 city zones confirm that the final step — processing — is not happening. The Board's photos from the ground further confirm this stagnation. In response to a Central Pollution Control Board alert over repeated violations, TNPCB has now issued formal directions to GCC under the Environment (Protection) Act, 1986. The civic body has been asked to comply with the 2016 rules, act against violators, and implement CPCB's 2017 guidelines on environmental management of C&D waste. The report concludes by urging the Tribunal to instruct GCC to restore operations at existing plants and install additional capacity, considering the city's daily waste generation. "They shut the Perungudi plant in August and Kodungaiyur in December, yet keep collecting 1,000 tonnes daily. Where is it all going? In Valmiki Nagar, over 50 tonnes were cleared once, but it came back in weeks. Without processing, the waste is just getting dumped elsewhere," said Karthikeyan, a Thiruvanmiyur resident.

Fishermen and activists raise alarm over microplastic pollution on Kanniyakumari coast, after debris from sunken ship washes ashore
The fishermen and the activists from the Kanniyakumari district have already been raising their concerns over the environment threats to their coastal habitat, including serious opposition against the proposed hydrocarbon project in the waters off Kanniyakumari. Adding to the list, there are serious concerns about tiny plastic pellets (nurdles) which have been washing ashore for the past few days along the coastal areas of Kanniyakumari. Earlier they were detected as far as Kadiyapattinam from Neerodi, but currently the spread has extended to Rajakamangalamthurai. While the debris that had washed ashore along the coastline of Kanniyakumari is described as non-hazardous, the pellets remain a dangerous pollutant. Their impacts and their breaking up into nano plastics, will eventually enter into the food chain, according to an activist from the district. Johnson Charles, another activist from Colachel said the people of Kanniyakumari and Kerala were known for their dietary habits, where fish plays a huge role. He added, 'So far, these tiny plastic pellets had washed ashore along the coast of Kanniyakuamri and Kerala. But once the southwest monsoon intensifies, there are high chances they will drift even further than the current places.' He noted that the sunken cargo vessel MSC ELSA 3 was carrying more than 600 containers, including containers having hazardous materials and other cargo carrying tiny plastic pellets and other materials. There was no adequate information available about the full list of contents. 'This will definitely cause prolonged and irreversible damage to the food chain,' he added. The major impact of these microplastics are some aquatic organisms mistake them as food, while other species may intentionally feed on them. The ingestion of chemically contaminated microplastic may introduce toxic pollutants into marine organisms and more widely into the food web. While these microplastics settle in riverbeds and seafloors, impacting the dwelling organism like crabs ,mussels and benthic worms. C. Berlin from Neythal Makkal Iyakkam, said, 'While officials are taking precautions to identify these materials and safely remove them, many unaware people from coastal hamlets are directly handling them out of curiosity, without knowing the risks involved.' He added that currently conservancy workers are engaged in removing these tiny pellets, but the government should take immediate actions to prevent the prolonged damage. He called for an accountability from the shipping company and responsible agencies. 'This is not just a local pollution issue, but a national environmental emergency in making,' mentioned Mr. Berlin. Speaking to The Hindu Kanniyakumari District Collector R. Alagumeena noted that scientists and a team of experts were engaged in taking samples from the affected site, to study about the short and long term effects of these microplastics, noting that it was too early to comment on the issue.

Plastic nurdle spill threatens 'Malabar' upwelling region
The sinking of the Liberian-flagged MSC ELSA 3 off the Kochi coast in Kerala on May 25, has triggered an environmental crisis along the Kerala and Tamil Nadu coast because it spilled plastic nurdles—tiny pellets used in plastic manufacturing—into one of the world's richest 'Malabar' upwelling regions. Upwelling brings deep, cold water to the surface, propelled as they are by strong ocean currents and the rotation of the Earth. There are five major upwelling regions determined by seasonal ocean current upwelling systems — the Canary, Benguela, California, Peru and Malabar. The Malabar Upwelling Region (MUR) stretches from Ratnagiri in Maharashtra to Kanyakumari in Tamil Nadu. Although these regions form less than 1% of world's oceans, they contribute to more than 25% of fish catch. Each support a rich ecosystem and commercially important fisheries. These large marine ecosystems are increasingly under threat from over-exploitation, pollution and habitat modifications. The Kochi plastic nurdle spill falls bang in the middle of MUR. Carrying 640 containers, including 13 with hazardous materials, the shipwreck scattered nurdles onto beaches from Thiruvananthapuram to Kanniyakumari, threatening one of India's most biodiverse marine ecosystems. This marks the first major nurdle spill in India caused by a shipwreck, raising urgent concerns about ecological and economic repercussions. Experts say the spill occurred as the upwelling system was taking shape where monsoon-driven winds lift nutrient-rich deep waters to the surface. This process fuels plankton blooms, sustaining nearly 50% of India's marine fish landings, including small pelagic species like Indian Mackerel (accounting for 30% of marine landings, with India producing 90% of the global supply, 77% from the west coast) and oil sardines. The region's high productivity, driven by sea surface temperature, salinity, and mixed layer depth, supports a complex food web, linking plankton to larger predatory fish and providing livelihoods for lakhs of fishermen. The spill's timing during the monsoon upwelling period, when productivity peaks, heightens the risk of disrupting this delicate ecosystem.
