11.12.2 Emissions and Controls 6-8 Particulate matter, consisting primarily of cement and pozzolan dust but including some aggregate and sand dust emissions, is the primary pollutant of concern. In addition, there are emissions of metals that are associated with this particulate matter. All but one of the emission points are fugitive in nature.

Portable Primary Impact Crushers are wheel-mounted rock crushing machines, engineered for primary crushing applications. These plants are extremely versatile and economical units and have proven their effectiveness in a host of missions like crushing soft and medium-hard materials such as limestone, low abrasive rocks, for quarrying, cement industry, concrete and asphalt …

Concrete currently accounts for about 8 percent of the carbon dioxide being emitted into the atmosphere, dwarfing the aviation industry's contribution of 2.5 percent. Concrete's contribution of CO2 is comparable to the entire agriculture industry, which is responsible for 9 percent of carbon emissions.

This encompasses many innovations, including new low-emission engines from the likes of , CE and Deutz (amongst others), integrated dust control systems on breakers, screens and crushers, as well as equipment that can be powered by either generators or mains electricity.
