Publication: «How much innovation is needed to protect the ocean from plastic contamination?»

  • We develop a system dynamics model to study the issue of plastic debris in the ocean.
  • Technological solutions alone cannot solve ecological issues in a growing economy.
  • Significant ocean cleanup requires removing at least 135 million tons of plastics.
  • Such a removal effort might cost up to €708 billion, i.e., 1% of the world GDP.
  • A diverse portfolio of solutions, in the ocean and on land also, performs better.
