The researchers found an average of around 100 microplastic particles per liter in glass bottles of soft drinks, lemonade, iced tea and beer. That was five to 50 times higher than the rate detected in plastic bottles or metal cans.
“We expected the opposite result,” Ph.D. student Iseline Chaib, who conducted the research, told AFP.
“We then noticed that in the glass, the particles emerging from the samples were the same shape, color and polymer composition—so therefore the same plastic—as the paint on the outside of the caps that seal the glass bottles,” she said.
The paint on the caps also had “tiny scratches, invisible to the naked eye, probably due to friction between the caps when there were stored,” the agency said in a statement.
This could then “release particles onto the surface of the caps,” it added.
Lets go back to corks
Corka Cola.
As someone in a cork industry, you really don’t want that.
What is this teasing? Elaborate.
It takes a lot of effort to soak the corks.
Its really hard to soak my own cork, so I just get my girlfriend to soak my cork instead.
I also get this guy’s girlfriend to soak my cork
She does have a lot of experience soaking cork
We know
Why?
Care to expand on why? I’ve had corks dissolve and break if I didn’t finish the drink quickly enough, just on liquor bottles that went unused for a year or so. Any other reason?
Slightly educated guess. True organic cork is produced by cutting the bark off specific trees. There are limited climates it grows. I would guess the scale with which we produce bottled drinks would require significantly more trees and labor that we currently have. And thus cork prices would skyrocket.
And you can’t really close them again.
