  6. 5.5.1 U.S. Types ofSDW

  7. 5.5.2 U.S. Management ofSDW

  8. 5.5.2 Management ofSW Manufacturing (56%) • scrap metal • plastics • paper • sludge • ash • Indirectly created by SDW Mining (14%) • rock and minerals (tailings) • dumped into waterways Agriculture (9%) • crop waste • manure

  9. 5.5.2 Management ofSDW Options • Landfill • Incineration • Recycling • Composting • Any more?

  10. 5.5.2 U.S. Management ofSDW

  11. 5.5.2 Landfill Issues Waste put into ground, and covered with soil, plastic, or both each day. • anaerobic decomposition produces methane • aerobic decomposition produces carbon dioxide • noise, smell, vermin • Leachates - seeping liquid into groundwater aquifers • Liners used, then encourage anaerobic decomposition • Finite amount of area

  12. 5.5.2 Incinerator Issues • do not separate materials • cleansers, batteries, paint • air pollution • dioxins • creates ash as byproduct • 10-20% of original mass • where does it go? • traffic • air & noise pollution • very expensive
