Treatment and recycling of shredder fluff: Final report on Phase 1, Proof of concept
This report describes the results of a study conducted by Argonne National Laboratory (ANL) to investigate the feasibility of extracting thermoplastics from shredder fluff for possible recycling. The objective of the research was to evaluate the technical feasibility of using organic solvents to selectively dissolve and recover thermoplastics from the shredder fluff. The basis of the process is physical separation of shredder fluff, which is followed by selective dissolution and recovery of thermoplastics from the plastics-rich stream. In small-scale laboratory runs, four potentially marketable products were recovered by the use of this process: clean polyurethane from (PUF), a mixture of polypropylene (PP) and polyethylene (PE), a mixture of polyvinyl chloride (PVC) and acrylonitrile-butadiene-styrene (ABS), and an iron-rich fine magnetic fraction. Because the residual shredder fluff has been preprocessed, it should be more homogeneous and have a much lower chlorine concentration and moisture content than the raw shredder fluff. These attributes should make the material more economically and environmentally attractive than raw shredder fluff as a fuel or feedstock for the production of fuels and chemicals. A preliminary capital cost estimate of the process was also developed.
