Reduce reuse recycle. Seems to be an interesting material for reuse.

Tho I don't know what to think about it for ecology. The material would most like still get into common trash and thrown into the wild.

Only 25% degradation in the ocean is conflicting. If the resin remains and cannot be degraded, well it's still pollution like plastic.

What happens to the material is burned in a trash incinerator? Does it release bits of resin in the air like plastic?

or when in the wild under rain or dirt?

Tho it still seems to be an interesting material which may allow for a easier repair or recicling of road material.

Decomposes in seawater...into what?

Unless the fishing industry adopts it, it won't matter too much
