I imagine a substantial part of this is the rusting of rebar in concrete structures. The problem of rebar has fascinated me, and one German company has begin making carbon fiber reinforced concrete instead of steel, with amazing results. You can reduce environmental waste by having structures last longer and you use less concrete. I'm looking forward to this becoming more ubiquitous.

AFAIU GRP rebar has become somewhat common lately, though this carbon fiber rebar seems to be a higher end step. Interesting to see how it'll develop.

Obligatory mention of Basalt rebar as well.
