Not sure the point is to recycle it but rather to have a more carbon friendly alternative to steel. It would also have the benefit of making us less reliant on steel in places where wood supply is ample.
And steel is 100% recyclable, indefinitely.
Hard to beat.
but steel doesn’t store carbon (except the small carbon input used to turn iron to steel)
wood, on the other hand, is a carbon sink.
Of course, over time we can increase the amount of industrial forest, but that will take 40-50 years.
Virgin steel requires the higher temperatures of a coke-fed blast furnace.
> Hard to beat.
Since wood is actually carbon negative, it still manages to beat steel.
