A method is disclosed for recycling polymer containers contaminated with oil, for example used HDPE motor oil containers, in an energy efficient manner, that does not require a costly washing step. The commercial value of the polymers is preserved by converting the contaminated polymers into value-added products. Composites are made from discarded motor oil containers, the residual motor oil therein, cellulosic fibers, and blending agents or other additives. In one embodiment, the process uses the residual oil to advantage as a fiber blending agent, or to make polymer types in a blend more compatible with one another. |
