Abstract

The objective of this study was to investigate the feasibility of using polyurethane (PU) foam wastes obtained from automobile shredder residue (ASR) in wood composite panel (fiberboard) production. PU foam wastes from ASR were picked by hand, cleaned by water and acetone, grounded into powders of two sizes (60 mesh and 120 mesh), and dried to remove moisture. The PU powders were characterized by stereomicroscope and then partially replaced pMDI resin at percentages of 10%, 20%, 30%, 40%, and 50% (based on the weight of pMDI resin). The PU powders were mixed with wood fibers to make fiberboards. The results showed that the addition of PU powders increased both the physical and mechanical properties of fiberboards. At replacing percentages from 5% to 30%, the properties of fiberboards increased. However, further increase of replacing percentages (from 30% to 50%) resulted in lower properties of fiberboard. When observed at a magnification of 125 times by a stereomicroscope, PU powders of 60 mesh had more foam features while PU powders of 120 mesh had more particle features. The fiberboards bonded by pMDI resin and PU powders of 120 mesh had better water resistance and mechanical properties than those bonded by pMDI and PU powders of 60 mesh. The use of PU powders in fiberboard production provided a new possible way of recycling PU foam wastes. The fiberboard has advantages of formaldehyde-free, better water resistance, higher mechanical properties, and lower material cost.
