The mission of The Ocean Cleanup is to develop and scale technologies to rid the world's oceans of plastic. Once the ocean plastic pollution has been extracted and recycled, it needs to be further processed and tested for use in new applications. 

Through extensive R&D, we have shown that we can transform the ocean plastic we collect into something of value. We now need to develop a portfolio of materials with harvested ocean plastic while staying ahead of the curve when it comes to available recycling technologies.

The Catch Management team is responsible for what happens with the collected waste after being extracted from the ocean. The goal is to repurpose ocean plastic into new products, helping to fund the continued cleanup, and giving supporters a tangible opportunity to join our mission to rid the world's oceans of plastic.

"The plastic pollution that we take out of the ocean is not easy to recycle, but it can be done. We are looking for a bright and curious Materials Engineer with thorough knowledge on plastics, who can help give the ocean plastic catch a second life."

Stella van den Berg, Catch Management Director.
