The Ocean Cleanup is heading back to the Great Pacific Garbage Patch with System 03, so Catching Up speaks to Senior Offshore Representative Grete Ernst ahead of her latest trip to the Pacific Ocean. Grete has front-row seats for the largest cleanup in history and shares her excitement at heading out once more. But Grete has many tales to tell from her time offshore, and she reveals what life is really like with the same crew for weeks on end, with land nearly a week’s journey away - as she says, almost like a different planet. In such a key year for our oceans, Grete tells us how she'll be helping us optimize System 03 following its winter upgrades to make us even more impactful and efficient in cleaning plastic. From the Global Plastics Treaty to the importance of creative thinking in engineering, Grete gives us the full picture of cleaning the ocean - from up close.
