Pollution Prevention of Metal Casting Industry

In recent years, environmental concerns of pollution and resource depletion represent major concerns for society. Air quality in the vicinity of large cities is linked with serious health hazards. Many of these health hazards are associated with nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the air, which in turn are caused by high traffic volumes and combustors. These pollutants may also travel long distances to produce secondary pollutants, such as acid rain or ozone (Beeldens 2006). Release and transfer reporting are limited to the approximately 600 chemicals on the TRI list. Therefore, a large portion of the emissions from industrial facilities are not captured by TRI.
