> But the widespread use of persistent, non-biodegradable glass that cannot be naturally eliminated causes long-term environmental hazards and social burdens.
I never quite understood this idea. Most modern glass is float glass. Its made of sand, lime and dolomite.
Want to turn it back into sand? Okay. Crush it. Viola; sand.

I don’t know what can be the use case of it, but for example a drone boat that can degrade, or a temporary shelter, or a temporary transparent solution.

Probably places we currently use disposable and semi- disposable clear plastic.

From what I can see, the cost of this glass - including the energy cost in production - would outweigh the cost of the plastic, including incineration after use.

Is there a link to the actual paper or is it the usual pay wall?

Glass doesn't need to be biodegradable and biorecyclable. You can degrade it and recycle it. Crush it up and melt it down.
Let's see some applications. Maybe it has some useful properties? Let's see some manufacturing techniques. Maybe it's cheaper to make, or requires less energy?

Biorecycling should definitely be cheaper since it's just using organisms to break the substance down into constituent compounds

I don't know what the preparations and costs for biorecycling is. How is it cheaper? What are the materials and processes and who is involved?

Glass is already pretty eco friendly. It lasts for anywhere from years to centuries so rarely needs replacing, most is non toxic, most can be recycled or reused. Not saying this isn't a neat advance, just that the use case might be kind of narrow.
