Resumen

AZAMBUJA, Rafael da Rosa; CASTRO, Vinicius Gomes de; TRIANOSKI, Rosilani  y  IWAKIRI, Setsuo. Recycling wood waste from construction and demolition to produce particleboards. Maderas, Cienc. tecnol. [online]. 2018, vol.20, n.4, pp.681-690. ISSN 0718-221X.  http://dx.doi.org/10.4067/S0718-221X2018005041401.

The objective of this study was to evaluate the feasibility of construction and demolition (C&D) waste wood to produce of particleboard. The raw material was obtained from a waste recycling company and it was divided into four types of materials: MDF (medium density fiberboard), MDP (medium density particleboard), plywood and timber. After reduction of these wood product residues to particles, particleboards were produced, in the UFPR Laboratory, with urea-formaldehyde resin and a target density of 0,75 g / cm³ and their physical and mechanical properties were determined. Particleboards made from industrial Pinus spp. particles were also produced as control samples. C&D wood waste showed potential for use as raw material for particleboard. The properties of particleboard made of recycled timber, MDP, plywood and the mixture of the four sources of material indicated that particleboard industries could use these waste resources for the production of the inner layer of MDP products.
