Abstract:
A method of formulating thermoplastic pellets for use in an injection molding process comprising the following steps:(a) obtaining an amount of a raw sludge material, the amount of raw sludge material including a percentage of water; (b) removing at least a portion of the water by exposing the raw sludge material to a dryer, thereby resulting in an amount of dried sludge material; (c) obtaining an amount of plastic material; (d) obtaining an amount of saw dust; (e) a shredding step, the shredding step comprising shredding the amount of dried sludge material and the plastic material; (f) a blending step, the blending step blending the amount of dried sludge material and the plastic material together with the saw dust to form a quantity of composite material; (g) placing the quantity of composite material into a grinder to form a ground composite material; (h) placing a quantity of the ground composite material into an extruder, thereby forming a stand; and (i) feeding the strand into a pelletizer to form pellets.
