The new plastic appears to be a vitrimer, which is a class of thermoset, so not well suited as a replacement for the types of polymer plastics that tend to junk

The new plastic appears to be a vitrimer, which is a class of thermoset, so not well suited as a replacement for the types of polymer plastics that tend to junk up the environment (thermosets, because of their durability, tend to have very long useable lifetimes -- I have milk crates I use for storage that are older than me!)
