The only problem is that the North Pacific Gyre, the worst of the Gyres, has a plastic density of 5.1 kg/km2 according to research cited in Wikipedia. Assuming that an empty bottle weighs 100 g (about 4 oz.), then a boat would have to trawl an entire square kilometer and collect every single piece of plastic in it in order to make 51 bottles [*]. Further, keep in mind that collecting these plastics pieces requires a very fine net and a slow moving boat.
So did Method Products and their partner Envision Plastics actually use a boat, all the while generating CO2 to collect all this plastic? No, of course not. Instead, they
"... tapped into a network of beach cleanup organizations, particularly in Hawaii. Hawaii is of the most remote land masses on the planet, and happens to sit at the southern edge of the Gyre. Because of the ocean winds and currents in the region, much of the plastic from the Gyre ends up washing up on the beaches of Hawaii."In other words, they collected plastic on the beach, called it "Ocean Plastic from the Great Pacific Gyre" and used that instead. How is this a "breakthrough"? How is it that no one seems to be calling them out on it? Sure, it is great that the plastic is being collected and recycled, (plastic that has no business being in the ocean in the first place), but to hype it as Ocean Plastic? That's where I have to draw the line. There are plenty of people working quite hard to actually provide true "green" products (yours truly included) and to see this junk get a free pass is quite maddening.
That Method Products makes a very large line of cleaning products adds further irony to calling this PR "greenwashing".
[*] Another estimate of the plastic in the Gyre is 8 m2 per km2. Any way you look at it, it s a very small volume, but people seem to imagine it looking like this:
