They stay there. It’s a problem. We don’t like it. And it’s the same when we litter the land with anything too. Our Sustain™ products however are not designed to end up in the natural environment and not even in a landfill. They are designed for a very specific waste stream for a very specific end of life: Sustain™ should get commercially composted to become a valuable resource after use, not just a one-and-done-forever material.
