ABSTRACT:
A method for recycling waste plastic material, from polymeric film or hydropulper waste, including plastic and cellulosic fiber or organic contaminants. The method includes the steps of introducing the waste plastic material into a size reduction unit, and reducing the size of the waste plastic material to particles having a maximum dimension ranging between about 1 inch and about 8 inches; mechanically hammering and rubbing the plastic material for separating a portion of the cellulosic fiber from the plastic; separating another portion of the cellulosic fiber from the plastic by flotation with agitation; further reducing the particle size of the plastic to a maximum dimension of about 1/2 inch; dewatering the plastic; drying the plastic to a moisture content of less than about 10 weight percent; and rolling the plastic into pellets.
