- 20% of the plastic in the entire device was recycled?

- 20% of the plastic in the box (as the context implies) was recycled?

- 20% of the recycled plastic was ocean-bound and the device is all or mostly recycled plastic?

- Is it some sort of 20% plastic-grade and the plastic was all ocean-bound?

- Did they capture ocean-bound plastic somewhere, used 20% for these boxes, and released the other 80% back into the ocean?

- Did they mean specifically "Ocean Bound Plastic" as a specific term (OBP) and not "ocean-bound-plastic" as a generic term? In that case, this website explains [0] that it would be 80% of all plastic that would end up in the ocean and that certifiable OBP is not commercially recyclable [1]. So... it's not OBP by definition then as OBP excludes all plastic that can be recycled commercially and this was?

When I clicked the 'Learn more' link next to it, the figure wasn't in the source page. There doesn't seem to be any source page for this, although a lot of news outlets are quoting it (in different interpretations). It seems like they were trying to greenwash something, though that article is wishy washy anyways.
