Buildings used iron from sunken ships centuries ago. The use of recycled materials should be business as usual by now

"At Fremantle Prison in the 1850s, when metal was scarce, the prison gate and
handrails were made from iron recovered from sunken ships. As I toured the
prison recently, I reflected on how similar the situation was when COVID-19
disrupted building supply chains across Australia. The shortage of materials
such as steel, which is still an issue, turned heads to using recycled steel,
which would otherwise be exported overseas for full recovery.

Do we really needed material shortages for the construction industry to get
serious about using products with recycled content? When resources are
depleted, does it only then mean it’s time to go sustainable?

It is encouraging to see many state initiatives to recycle construction
materials, such as Roads to Reuse in Western Australia. It offers a $5 per
tonne incentive to use recycled materials such as road base and drainage rock
for construction projects.

Are such programs enough to ensure the supply of construction materials is
sustainable? No, and if you look back at the examples of the past two
centuries, industry-wide reuse of such materials should have been business as
usual by now."
