| Abstract: | The cement industry is fulfilling the role of "scavenger" in industrial ecology (IE) by using a variety of secondary materials and fuels. In dealing with hazardous elements (here as: hz-elms.) of the wastes, there are has side effects such as relatively significant stack emissions. Emissions and leaching potential may be substantially lowered by reducing levels of hz-elms. in wastes before being included in cement production and by selectively capturing mercury from stack gases. This paper presents an analogy to metabolic functions of selective uptake, sequestration, and selective excretion. |
