Abstract

The use of alternative materials such as lignocellulosic residues in the production of particleboards has increased considering that these residues are produced in large volumes and often do not have an appropriate destination. This research studied the use of residues from cellulose industries, sugarcane bagasse, and castor oil-based polyurethane resin in the production of wooden panels and evaluated the influence of using these residues on the physical and mechanical properties of the panels. The products were manufactured according to the Brazilian standard ABNT NBR 14810 and the requirements of the panels were evaluated based on national and international standards. All treatments partially met the regulatory requirements. The addition of bagasse led to an improvement in physical and mechanical properties, with treatment 2 (50% wood residue and 50% bagasse) presenting the best performance, which indicates the possibility of using panels with residues with non-structural purpose in environments to improve the thermoacoustic performance of rural buildings. The statistical analysis indicated that the percentage of bagasse was significant, improving the evaluated properties.

Highlights

IntroductionThe use of engineered wood-based products, such as particleboards, medium-density fiberboard (MDP), oriented strand boards (OSB), and plywood panels has increased in rural structures, being an alternative to the use of sawn wood in buildings for structural use and ambiance, improving thermal and acoustic comfort in buildings ((Bertolini et al 2019a; Bertolini et al 2019b; Garzón-Barrero et al 2016; Labans et al 2017; Scatolino et al 2017; Souza et al 2014; Zhou & Pizzi 2014).Particleboards, panels composed of processed wood and resin, joined under pressure and heat, stand out among these products (Ihnát et al 2017; Iwakiri et al 2005; Negrão et al 2014; Silva et al 2015)
These residues may consist of corn ears (Paiva et al 2012), poppy particles (Keskin et al 2015), sugarcane bagasse (Fiorelli et al 2013; Hofsetz & Silva 2012; Sugahara et al 2019), and residues from the pulp and paper industry (Elliott & Mahmood 2007; Mäkelä et al 2012)
This research aimed to evaluate the physical and mechanical properties of particleboards made with residues collected from paper and cellulose industries from Eucalyptus urophylla, Eucalyptus grandis, and Eucalyptus camaldulensis, sugarcane bagasse, and castor oil-based bicomponent polyurethane resin, as well as check the possibility of using these panels based on normative requirements

Introduction

The use of engineered wood-based products, such as particleboards, medium-density fiberboard (MDP), oriented strand boards (OSB), and plywood panels has increased in rural structures, being an alternative to the use of sawn wood in buildings for structural use and ambiance, improving thermal and acoustic comfort in buildings ((Bertolini et al 2019a; Bertolini et al 2019b; Garzón-Barrero et al 2016; Labans et al 2017; Scatolino et al 2017; Souza et al 2014; Zhou & Pizzi 2014).Particleboards, panels composed of processed wood and resin, joined under pressure and heat, stand out among these products (Ihnát et al 2017; Iwakiri et al 2005; Negrão et al 2014; Silva et al 2015). One possibility of reducing wood consumption as panels is the use of lignocellulosic residues to produce cleaner and more ecological (Fiorelli et al 2013; Keskin et al 2015) These residues may consist of corn ears (Paiva et al 2012), poppy particles (Keskin et al 2015), sugarcane bagasse (Fiorelli et al 2013; Hofsetz & Silva 2012; Sugahara et al 2019), and residues from the pulp and paper industry (Elliott & Mahmood 2007; Mäkelä et al 2012). Brazil has a vast sugarcane production area, with annual cultivation of approximately 620 million tons (CONAB 2019), producing a large volume of bagasse, which is largely used for energy production by burning it (Hofsetz & Silva 2012) It is a major producer of paper and cellulose, with an annual production of 10 and 18 million tons annually, respectively (Indústria Brasileira de Árvores – IBÁ 2017). This industrial production process emits a large volume of residues, such as bark and branches of Eucalyptus, which are mostly used for energy production
