The Washington-based Institute of Scrap Recycling Industries (ISRI) has released the final results of its “Mixed Waste Processing & Desirability of Recovered Paper Market Survey” report, which finds that paper mill buyers perceive scrap paper generated by mixed waste processing facilities (dirty MRFs) to be “generally deemed unusable by pulp and paper mills.”
Through the survey, ISRI found that 25 percent of the respondents purchased paper from dirty MRFs, and 70 percent of those purchasers found the quality of paper “to be worse than other recovered paper.” Because of this experience, 90 percent of those purchasers have had to reject or downgrade mixed-waste recovered paper at a higher rate than recovered paper from regular MRFs (material recovery facilities). None of the participants used dirty MRFs as their majority material supplier, according to the report.
The primary reasons listed by participants as to why they would not purchase paper from dirty MRFs are:
- low quality;
- higher than acceptable percentages of prohibitives and outthrows;
- internal quality standards;
- fear of risk;
- excessive moisture;
- concern for customer needs;
- regulatory concerns; and
- lack of availability in geographic area.
