Plastic waste is a problem on our beaches. Hence, it is largely removed in a coordinated manner within a few weeks. However, it can litter other coasts of the world for many months to years due to unregulated waste disposal. Often the garbage on the beach is simply burned and a special form of plastic waste is created: so-called plastiglomerate. This ‘rock’ is made up of natural components, such as coral fragments, held together by the melted and reconsolidated plastic. A new study has now demonstrated, using field samples from Indonesia, that such rocks pose an increased environmental risk to coastal ecosystems such as seagrass beds, mangroves or coral reefs. The melted plastic decomposes more quickly into microplastics and is also contaminated with organic pollutants.
