Abstract

Abstract This study evaluated the quality of the particleboard produced with particles generated from mobile discharges with mixture of equal parts of industrial particles of Pinus. The material was collected and processed in the form of chips by a company specialized in waste recycling. The experimental plan consisted in producing panels with nominal density 0.55, 0.70 and 0.85 g/cm3, and urea-formaldehyde resin of 8, 10 and 12%. The increased density and resin content contributed to improve the physical and mechanical properties of the panels. The panels produced with nominal density of 0.70 and 0.85 g/cm3, and 10% resin content, showed better feasibility of using mobile discharges particles in a proportion of 50% mixture with particles of Pinus industrial production of particleboards.

Highlights

AND OBJECTIVESThe recycling of wood-based products is increasingly more important for the forest-based industry due to its positive impact on both the environment and the production chain of consumer goods
Panels produced with nominal density of 0.85 g/cm3 and 12% (T9) of resin presented a statistically equal mean in comparison to panels made with density of 0.85 g/cm3 and 10% (T6) resin content; in general, lower than the other treatments, for both absorption properties (Table 2)
Panels produced with nominal density of 0.85 g/cm3 and resin content of 12 and 10% (T9 and T6), are statistically equal and higher than the other treatments (Table 5)

Summary

Introduction

The recycling of wood-based products is increasingly more important for the forest-based industry due to its positive impact on both the environment and the production chain of consumer goods. Such process involves collection, separation and cleaning, allowing fewer new products to be manufactured, saving raw material, inputs, and contributing to reduce energy consumption. In this context, the aim of this research was to produce agglomerated panels consisting of particles generated from furniture wastes and industrial Pinus particles, mixed in equal proportions, with different densities and urea-formaldehyde resin contents
