Parking lots are made from asphalt, a coal/coal tar derivative. It has pollutants in it.
Gee. No asphalt, no cement, no modern America.
Obama the Red will get his wish - America will become a 3rd World shithole just like his father’s country Kenya and Indonesia, where he spent his younger years.
Hey, liberals. You voted for this clown. Hope you remember this when you stand in the unemployment line.
If spit, chewing gum and baling wire were good enough for....
OTOH, I can just see retreaded Hippies picketing with signs, "Cement relationships, not Mother Gaea!"
IIRC, about 30 or so years ago, some contractors tried that on a couple of highway overpasses in Nevada.
Didn't work then; won't work now.
Cement production is a HUGE emitter of CO2 as calcium carbonate (CaCO3) is “calcined” to CaO + CO2 on its trip through the kiln. I’m very surprised this article focused on nitrogen oxides instead of CO2 as a reason to shut down the kilns.
But, if TX takes the CA lead, they use CO2 as another reason to force them out of business. I hear there’s lots of cement we can import from Mexico.

“They paved paradise to put up a parking lot”
I think a number of folks are missing the point of the original SA Express-News article. That’s not surprising...since it’s not exactly a decent newspaper.
The point is that San Antonio is ONE tick away from hitting a number of clean air restrictions that we currently do not have to live under. These are things like emissions testing when you register your car...restrictions on industrial emissions, etc. Basically things that would make living here have a number of hurdles that are not currently in place.
It sounds silly...but the city is trying to AVOID regulation by asking the cement plants to do a temporary shutdown. I live about three miles from one of the plants in question.
Part of the Collisseum in Rome is concrete. It was around long before Mo started that mess.

Well they are going to drive up the price of everything and more expensive cement leads to “Bad” Ideas.
Asphalt, the paving material, is made from aggregates and bitumen (also called asphalt or asphaltic cement), a petroleum product, not coal tar derivatives. Asphalt sealers are often coal tar derivatives, though.
Maybe we can export enough jobs to Mexico that the illegal immigrants will move back there for work.
Keep in mind that the cement kilns in Texas and the nation are all burning hazardous waste, sometimes even tires. Except they don't call it burning, its "thermal oxidizing".
“I hear there’s lots of cement we can import from Mexico.”
I hope it is better than half-baked Mexican brick. Nor would increased importation help our trade imbalance. What happens when the EPA shuts down all domestic industry and the worthless dollar shuts down importation? We are being reduced to a 3rd-world country — by design. Is anyone fighting mad yet?
China already uses 50% of all the cement produced world-wide every day.
The cost of cement here has more than doubled in the past 4 years. My share must be in the big dam holding back 3 rivers in China.
