About one-eighth of Tyne plastic pellets may have remained in estuary after six weeks
A Newcastle University model of tides, river flow, wind and waves estimated about 2.2 tonnes of pellets remained in the estuary on August 30.
Event / data period:
Published: · Updated:
A vessel collision at the Port of Tyne on July 19, 2026, released an estimated 17 tonnes—about 850 million small plastic pellets—into the river. A modelling update published by Newcastle University on October 12 estimated that after accounting for cleanup removals, about 2.2 tonnes, roughly one-eighth of the spill, may still have been in the estuary on August 30.
The team modelled the tidal Tyne and neighbouring North Sea, representing tides, river flow, wind and waves, and tracked 10,000 virtual particles released at the spill location. The university said the estuary findings were more robust, while offshore pathways were less certain and sensitive to assumptions. It expects autumn and winter high flows could move some remaining pellets downstream and plans to test the model with direct field measurements.

Tyne spill model scope and reported estimate
The table summarizes the university model scenarios and their uncertainty limits.
| About 2.2 tonnes may have remained in the estuary on August 30 | 2.2 | - | Model estimate after accounting for cleanup; roughly one-eighth of the initial spill, not a direct count. |
| 10,000 virtual particles tracked | - | 10000 | Particles released in the model at the time and location of the spill; offshore pathways were scenario-dependent. |
Methodology
This table reflects the model description and results in Newcastle University's 12 October 2026 release. The model includes tides, river flow, wind and waves; confidence differs between estuary findings and offshore scenarios. Figures are study estimates, not a direct count.
