I think what you win with it is just in the article, at least what they think they win now.

Less toxic substances, simpler constructions.
Electromagnetic waves and the earth’s magnetic field are not or less well stopped.
Not debris that kind of randomly falls on the earth.
The fact that it does not burn completely depends on many factors, thickness, material, combustion duration, etc.
Aluminum first melts, then starts to boil and turns into gas, very different from wood, different types and also very different from the printed circuit board of a satellite and again very different from the solder joints and so on.
I only welcome the fact that research is being done.
Wood is also easy to work with. As an astronaut, I see myself more easily driving a screw into a piece of wood than having to weld a metal plate to something.
