Plastic Nurdle spill – Nurdles still in the environment

During Typhoon Vicente which hit Hong Kong on 23 July 2012 a container ship near Hong Kong lost 7 x 40 foot containers. Six of these containers were each loaded with 1000 x 25 kilogram bags of Plastic Nurdles (pre-production Plastic Pellets). Five of these containers have since been located. All of them had lost some or most of their contents.

These bags and loose Nurdles started washing up on Hong Kong beaches soon afterwards. The majority of Nurdles which washed up on our shores were recovered during a massive volunteer cleanup operation which was initiated immediately after the spill.

Because Typhoon Vicente occurred during a high tide accompanied by a mini storm surge, many loose Nurdles were pushed high up into the rocky shores, coastal undergrowth and seawalls in Hong Kong.

These will slowly be flushed out of these locations by rainstorms, high tides and tropical storms and continue to wash up on our beaches in ever decreasing numbers for many months to come.

The following photographs were taken on 6 September 2012 to illustrate the problem.

Plastic Nurdle spill – Missing container

During Typhoon Vicente which hit Hong Kong on 23 July 2012 a container ship near Hong Kong lost 7 x 40 foot containers. Six of these containers were each loaded with 1000 x 25 kilogram bags of Plastic Nurdles (pre-production Plastic Pellets). Five of these containers have since been located, but one is still missing.

During Typhoon Kai Tak which hit Hong Kong on 16 August 2012, 80 full bags of Nurdles and many loose Nurdles washed up on beaches and shores from Mui Wo to Chi Ma Wan. See the photographs below of bags of Nurdles which washed ashore near Shap Long on Chi Ma Wan peninsula (Courtesy of Merrin Pearse at Coordinate4U). This suggests the missing container is possibly on the seabed in the vicinity of Hei Ling Chau. Searches have failed to find it.

If the container still contains part of its cargo, it is possible that full bags and loose Nurdles will leak from the container during future storm events, and these will wash up in the Mui Wo to Chi Ma Wan area. On the other hand, it could be empty by now, in which case there will be no future spills of bags or Nurdles. Irrespective of the containers status, the infrastructure is now in place to quickly and effectively respond to such a spill should it occur.

Plastic Nurdle spill – Understanding the science

To understand the science of plastic pellets, the following research papers at Algalita.org give an idea of some of the issues surrounding plastic pellets in the environment, particularly their impact on marine and bird life:

Plastic Nurdle spill – FEHD plastic pellet collection points

On many beaches, FEHD have set up plastic pellet collection points. If you see one of these signs, can you please leave any bags with collected pellets, or other rubbish next to the sign. This will make it easier for FEHD to remove rubbish which has been collected during the cleanups. Please see the photographs below:
