ABSTRACT:
A method for treating extremely small particles of plastic comprises providing a quantity of plastic particles having an average mean particle size ranging from about 0.0005 inch to about 0.05 inch in diameter, heating the plastic particles to a temperature sufficient to cause at least a portion of the plastic particles to adhere to one another, and forming the adhered plastic particles into pellets, said pellets having substantially the same average surface-to-volume ratio as the bulk, un-adhered plastic particles.
