Coffee husks: - A possible wood substitute in the particleboard industry

Abstract

Coffee husks, a waste by-product from coffee processing has been used as particles with hydrolysed tannin and urea formaldehyde as binders to make homogenous coffee husks particleboards. The resulting particleboards were subjected to physical and mechanical tests and a comparison made with the existing agricultural waste particleboards and the Standards. Results indicate that coffee husks/tannin particleboards had higher physical and mechanical properties compared to coffee husks/urea formaldehyde particleboards and that their properties compared well with other agricultural waste/residue based particleboards.
