Parallel to making preparations for the upcoming Pilot Phase, The Ocean Cleanup’s crew has carefully listened to all peer review comments and other feedback, based on which a series of several thousand edits have been implemented.
Some notable improvements include:
- Inclusion of recent studies on the economic and toxicological impacts of plastic pollution
- Inclusion of fishing for litter in the consideration of alternative cleanup methods
- Inclusion of discussion of the effects of current variability
- Inclusion of wind load
- Correction of the current velocity load from 50% to over 95% of conditions
- Inclusion of comments on corrosion of tension and connection cables
- Inclusion of discussion on how the skirt angle may influence catch efficiency
- Expansion of biofouling chapter
- Inclusion of discussion on the ichthyoplankton impact of the system
- Inclusion of results of Rotterdam harbor bycatch experiment
- Updated outlook on the Pilot Phase
The report’s main conclusion – that The Ocean Cleanup Array is likely feasible and financially viable method to cleanup nearly half the Great Pacific Garbage Patch in 10 years – remains unchanged.
“There’s obviously a lot more work to do – we estimate the technology should be ready for full-scale implementation in three to four years’ time. Now that we are confident the first phase has produced a solid basis, we can now close off the feasibility study, and fully focus on initiating the Pilot Phase”, Boyan said.
