we got rid of the old one.
it's great in the moment,
as we keep doing this,
there is really no way.
it typically goes into a landfill.
di solito finisce nella discarica.
which is not going to go away,
che non andrà più via,
1.3 billion tons of material every year

if we started thrifting.
dovremmo essere parsimoniosi.
when they go into products
quando diventano prodotti
When can they be used again?
quando possono essere riutilizzati?
the way we think about waste,
in cui pensiamo ai rifiuti,
the word "waste" completely.

over the last couple of decades
are getting smart at thrifting,

verso le macchine elettriche,
they can recycle up to 90 percent

with architecture has always been

about taking down.
non pensiamo a demolire.
we don't disassemble, we demolish.
non disassembliamo, ma demoliamo.
of all landfill waste in the US

from old demolition waste,
da scarichi di demolizione,
the rubble, the concrete.

and geotagging,
e con il geotagging,
when it comes to buildings.
which is being demolished,
being built here can use?

in that building are still usable?
sono riutilizzabili?
into a new building,
any value in the process?
to create thrift?
per essere parsimoniose?
