JIMENEZ, P. V. et al. Using waste from carpentry of Prosopis alba and Pinus sp. in the manufacture of particleboards. Quebracho (Santiago del Estero) [online]. 2016, vol.24, n.1, pp.26-27. ISSN 0328-0543.

This research was aimed at investigating the technical feasibility of using carpentry wastes to produce indoor particleboards. The particles came from the Prosopis alba Griseb and Pinus sp. wood planning in the carpentry at the Institute of Wood Technology (IWT) of the Faculty of Forest Sciences, Santiago del Estero, Argentina. Only-algarrobo, only-pine and a 50-50 % mixture of both were the three types of panels produced. It was done this way for the isolated effect of each of the particles (i.e. specific weight, moisture content, particle geometry, wood acidity, bark use) can be determined. The particles were glued using urea-formaldehyde resin. The particle boards made were tested on their moisture content, specific weight, 2 to 24 hs thickness swelling and bending strength variables in accordance with the DIN standards. For the statistical analysis of the results, a completely randomized three treatments and five repetitions was used. The properties were lower than required by the DIN standards. It is thought that this is mainly due to the low values was the shape and dimensions of the particles. According to the results, the only-algarrobo particleboards were those that best behaved under these study conditions.
