![]() Refusals can occur from something as ubiquitous as residential failure to RINSE out plastic containers. We learned many valuable lessons from which we could build upon and optimize the technology on our road towards system validation.In some locales (or where they accept it, recyclers merely collecting their tax-payer fees and turning around and sending the material to the landfill. It was the first time we successfully tested our technology in its intended environment, the Great Pacific Garbage Patch. With these understandings, the engineering team developed solutions to address both issues and incorporated them into the next iteration design- System 001/B, which we trialed later in 2019. Regarding the fracture, we determined that stress concentrations at the weld points in the dovetail connections caused the material fatigue. It was concluded that the system needed to maintain a consistent speed through the water to effectively catch and retain the plastic. We conducted a root cause analyses for the ineffective plastic retention and the structural failure. Using the insights and data collected from System 001’s time offshore, we went back to the drawing board. Dubbed “unexpected learning opportunities”, these challenges gave us a greater understanding of the Great Pacific Garbage Patch environment and how our system behaves in it. Of course, this was not the planned conclusion of the System 001 operations, but, as is expected with iterative design, discovering the flaws in our design is essential for success.
