Months after Tyne nurdle spill, key questions remain

On July 19, about 18 tonnes of plastic nurdles, roughly one billion tiny pellets, spilled into the River Tyne after the wind turbine installation vessel Wind Orca collided with a container ship at the Port of Tyne. Believed to be Europe's worst recorded incident of its kind, it has left volunteers still collecting microplastics on north-east England's coast.
