Development and Evaluation of Wood Boards comparing three sustainable adhesive formulations in their manufacture
The growing environmental concern and the adverse health effects due to the use of formaldehyde-based adhesives in the particle and fiber boards manufacture, promote an interest in the development of sustainable adhesives in the manufacture of wood boards. Therefore, the aim of the present study is to displace formaldehyde by considering alternative aldehydes, as well as substances originated as industrial by-products, including reported bio-adhesives based on depolymerized lignin. Furthermore, we have tested a non-volatile and non-toxic aldehyde, inside the manufacture of particle and fiber boards. The boards formed during this study were subjected to the determination of physical and mechanical properties of particles and fibers boards under the criterial of international standards: ASTM D 1037 12, to link them with the characteristics of the adhesive formulations implemented. Our results achieve insights on the development of the next generation of lignocellulosic materials.
