ROFL!!! Contaminated = PERFECT FEEDSTOCK. We've already been over this.
And what do you know?
"Some of these plastics are films that are too contaminated for recovery at retail outlets. While these items cannot be mechanically recycled, they are the perfect feedstock materials for PTF systems." "Many paper recycling mills receive sizable volumes of mixed, contaminated plastics in the bales they purchase. The level of contamination that occurs during the paper pulping process leaves the plastics covered in ink. However, because most modern pyrolysis systems can tolerate a wide range of contaminants, these plastics make an ideal feedstock for fuel recovery" http://plastics.americanchemistry.com/Plastics-to-Oil
