Use of Sugarcane Bagasse for Particleboard Production

Abstract

The use of agricultural residues for particleboard manufacturing increases their value-add and help meet the growing demand of raw materials for the panel industry. Accordingly, the aim of this study was to assess the quality of particleboards produced only with sugarcane bagasse or along with Pinus and Eucalyptus wood. The experimental design consisted of 5 treatments: T1) Eucalyptus panels, T2) Pinus panels, T3) sugarcane bagasse panels, T4) 50% Eucalyptus and 50% sugarcane bagasse panels, and T5) 50% Pinus and 50% of sugarcane bagasse panels. For each treatment, three panels were produced using 8% urea-formaldehyde adhesive, with 0.65 g/cm3 apparent density, 160°C pressing temperature, 4 MPa pressure, and 8 min of pressing time. The analyses revealed that use of sugarcane bagasse for particleboard manufacturing resulted in improved water absorption and thickness swelling properties after 2 h of immersion in water. In addition, the panels produced with bagasse only showed significant reductions in the mechanical properties. However, the use of sugarcane bagasse along with Pinus or Eucalyptus wood allowed the manufactured panels to meet all the conditions required by the CS 236-66 [1], ANSI A208.1 [2], and EN 312 [3] standards.

Properties of particleboards made from sugarcane bagasse particles

“…There was a tendency of the panels with smaller particle size to present lower values for TS2h and TS24H. Mendes et al (2014) found 4.5 and 17.8% for TS2h and TS24h. Brito et al (2020) obtained average values of 14.41 and 44.75% for panels made up of bagasse only for TS2h and TS24h, respectively.…”

“…The modulus of rupture values were compatible with those reported in the literature. Mendes et al (2014) found 12.5 MPa and Brito et al (2020) obtained 11.77 MPa. Panels with higher compaction rates can damage the particles, reducing their resistance and causing a reduction in the mechanical properties of the panels (Milagres et al, 2019).…”

“…Of using waste for manufacturing particleboards made from sugarcane bagasse is important from the social, economic, and business perspectives. Some studies carried out by Mendes et al (2014), Fiorelli et al (2016), Soares et al (2017), Silva et al (2018, Buzo et al (2019) and Nakanishi et al (2019) have demonstrated that this waste has the potential to produce panels, associated or not, with other lignocellulosic materials. In a study conducted with sugarcane bagasse Soares et al (2017) observed that this material contains high amounts of extracts, substances that can affect the curing of the resin and the adhesion between particles, in addition to cells with less stiffness and more damaged because of the sugarcane milling process (Mesquita et al, 2017(Mesquita et al, , 2019.…”

Thermal Modification of Sugarcane Waste and Bamboo Particles for the Manufacture of Particleboards

“…Agroforest and industrial waste are also used for the manufacture of particleboards, since they not only add value to the product, but also provide sustainability, reduce environmental pollution problems and help particleboard industries meet their demands (Negrão et al, 2014). Some studies have pointed to the use of sugarcane bagasse for the manufacture of particleboards (Fiorelli et al, 2013(Fiorelli et al, , 2016Mendes et al, 2014). However, one of the technological obstacles for its use in reconstituted particleboards is its dimensional instability in comparison to particleboards manufactured from wood particles (Freire et al, 2011).…”

Produção e avaliação da qualidade de painéis aglomerados constituídos por partículas de bagaço de cana-de-açúcar e bambu

“…No Brasil, exemplos de estudos sobre a produção experimental de painéis aglomerados de bagaço de cana, associados ou não com outros materiais lignocelulósicos, são os realizados por Pedreschi (2009), Barros Filho (2009, Belini et al (2010), Fiorelli et al (2011), Mendes et al (2014) e Barrero (2015). Os resultados destes estudos indicaram a viabilidade do emprego do bagaço, uma vez que as propriedades dos painéis atenderam aos requisitos das diferentes faixas de uso propostas pela norma padrão que utilizaram.…”
