Three heavy-duty truck manufacturers exhibited concrete mixer-bearing models with diesel engine exhaust systems configured for EPA 2010 compliance. Mack Trucks showed a Granite-mounted Beck Industrial mixer, stopping in Las Vegas prior to delivery to TexasÌ Nelson Bros. Ready Mix Ltd. The truck's MP engine is equipped with the ClearTech diesel emissions control system, based on Selective Catalytic Reduction (SCR), with exhaust treatment components underneath the cab's driver and passenger sides, plus the rear passenger corner.

Freightliner Truck displayed a McNeilus mixer on an M2 chassis powered by a (Detroit Diesel) DD 13 engine, which also uses the SCR exhaust treatment method to meet EPA 2010 emissions and particulate matter guidelines.

Navistar International Corp. is the only heavy-duty truck manufacturer deploying an SCR alternative, Exhaust Gas Recirculation, to comply with new diesel engine emissions regulations. The manufacturer exhibited a WorkStar 7600 powered by a MaxxForce 13 EGR engine. In lieu of diesel exhaust fluid and additional catalytic components, the EGR treatment mechanisms are mostly internal to the engine.
