OK, this is very interesting. One of the biggest limitations with biodegradable plastics is that they’re water-soluble, which makes them useless for most food packaging applications.
If this only breaks down when exposed to saltwater at particular concentrations it might be a lot more useful.
That said, the article’s not specific on which salt… I assume NaCl because that’s the highest concentration in seawater, but that doesn’t necessarily mean that other salts won’t cause the breakdown to start… and the environment isn’t exactly salt-free. Most foodstuffs aren’t de-ionized either.
This is weird. How did “Kick” have access to Bench’s customer list? Is there some relationship between these companies?
