NRMCA and its Truck Mixer Manufacturers Bureau (TMMB) affiliate question cost and weight factors attending a prospective National Highway Traffic Safety Administration (NHTSA) requirement that heavy-duty trucks bear stronger rear underride guards than presently compliant models. Preliminary estimates indicate the newer guards would add $307–$453 and 169–210 lb. to vehicle cost and weight, and represent $925 to $1,505 in life cycle fuel consumption.

Targeting lower net carbon dioxide emissions in portland cement milling, University of California, Los Angeles researchers propose introduction of calcium hydroxide, or hydrated lime, at the calcination phase, when high temperatures split limestone raw feed into CO2 gas and calcium oxide. Lab-scale tests in their National Science Foundation-backed investigation indicate the potential to sequester CO2 and recreate limestone in a continuous loop.
