| Abstract | The constituents of municipal solid waste are identified along with relative weight percentages typically found. Recycling priorities are established with respect to realistic criteria. Though the study was performed for Erie, Pennsylvania, concepts may be applied elsewhere. Paper, ferrous metals, aluminum, and rubber tires are listed, in that order, with respect to desirability of extraction. Tin cans, glass, and plastics are listed next under additional criteria. A survey of current technology is presented that briefly discusses unit processes as well as complete systems under development. Many unit processes are found to be an outgrowth from mining practices. A device called the 'Bowerman Classifier' is presented and incorporated into a system with potential to separate preprocessed municipal waste. The device operates on the principle of Stoke's Law applied to a moving fluid. All else being held equal, settling velocity will be proportional to density and thus a separation may be effected.
