Safety and Environmental
Considerations
In addition to its economic advantages, aluminum recycling has desirable environ-
mental benets. Chapter 1 pointed out that production of aluminum from recycled
sources reduces CO
2
emissions to the atmosphere by 90% compared with primary
metal, in addition to reducing uoride and SO
2
emissions. The production of sec-
ondary metal reduces energy usage by over 90% compared with primary metal and
reduces the amount of waste generated by 90%.
However, the technology of aluminum recycling presents potential hazards of its
own to both the work force and the general public. As the tolerance of the public f ...
