Abstract
A method of recycling a thermosetting polymer object of arbitrary shape includes: operating a fixture device to hold and rotate the thermosetting polymer object; operating a smart and modularized water jet cutter device to shatter the thermosetting polymer object outside-in into a wet polymer powder; drying the wet polymer powder; flattening the partially dried wet polymer powder; completely drying the flattened wet polymer powder; and separating the dried polymer powder into first and second groups, the particle size of the first group dried polymer powder being greater than a predetermined value, the particle size of the second group fried polymer powder being not greater than the predetermined value.
