Cement Production is Third Largest CO2 Producer by Country

[Rick C]

That's pretty amazing. There is a trade group that wants cement makers to sign up to be carbon neutral by 2050. Given that CO2 is produced by the chemistry of making Portland cement, I think that is a tall order, not to mention all the energy required to heat the slurry.

2050 is 30 years away, but still...

And the process is used to dispose of nasty things that there's really no better way to dispose of.

I work in this old building... you can see the pieces
of steel and such buried in the floors.
(They built model T's in this place.
Years ago.)
Hmm the website's iffy.
here's the history page.

The sad part is about Trico, which left for elsewhere
(Mexico?) in the late 80's.

I mean nasties go into the cement kiln. It makes them safe & adds fuel. Medical waste, toxins etc.
