  • Microplastics pollute water in rivers and oceans everywhere too.
  • Researchers use algae to catch tiny plastic particles.
  • Scientists changed the algae to make it water-repellent.
  • Water-repellent algae stick to microplastics and join together.
  • The algae and microplastics form heavy clumps that sink.
  • The clumps fall and make a solid layer.
  • The solid layer is easier to collect and remove.
  • Algae can grow in dirty water and help clean.
  • Collected particles can be used to make new products.
