The process of grinding and shredding scrap metal generates heat, resulting in residual fluids and fuels becoming gases. The violent nature of the process creates the potential for particulate matter emissions of various sizes. Thus, the process generates emissions of VOCs, particulate matter, and hazardous air pollutants including lead, zinc,

The cement industry is the second largest industrial carbon emitter and currently emits 7% of global CO2 emissions. The global population is expected to grow an additional 30 percent by 2050, increasing thus the need for buildings and transport infrastructure (e.g. roads, bridges, tunnels…), and the global demand for cement.

AP-42, Compilation of Air Pollutant Emissions Factors, has been published since 1972 as the primary compilation of EPA's emissions factor information. It contains emissions factors and process information for more than 200 air pollution source categories. A source category is a specific industry sector or group of similar emitting sources.

EMISSIONS AND CONSUMPTIONS Emissions The processing of clays and other ceramic raw materials inevitably leads to dust formation – especially in the case of dry materials. Drying, (including spray drying), comminution (grinding, milling), screening, mixing and conveying can all result in a release of fine dust.

Consequently, mining and smelting also contribute significantly to the world's greenhouse gas (GHG) emissions – at some 9% of carbon dioxide emissions. Again, a relatively small portion of just 1,8% is from mining and mineral processing, while 7,2% is from smelting and refining. Within the sub-category of mining and processing, comminution ...
