Influence of Leather Fiber on Modulus of Elasticity in Bending Test and of Bend Strength of Particleboards

Abstract

The society's development provides consequences such as the increasing generation of industrial waste. In the city of Franca, São Paulo's inland city, there are footwear industries that generate a large amount of leather waste during their production process. In most cases, there's no use of this waste and they're disposed of in landfills. A reuse alternative is the production of particleboards used in construction sectors. Therefore, one of the biggest challenges is the use of this leather waste adding value to the product and enabling the production of sustainable material. This work proposes the production of particleboards from Eucalyptus wood and leather fibers using castor oil polyurethane adhesive. In addition, the assessment of the leather fiber influence on modulus of rupture and elasticity obtained from a static bending test. The study investigated the proportion of 10%, 25% e 50% leather waste in relation to Eucalyptus particles and 10% castor oil polyurethane adhesive. The mechanical performance of the panels was evaluated based on ABNT NBR 14810-1 and 2 (2013;. The results allowed us to ascertain that the incorporation of 10% leather waste in particleboard rated them, according to NBR 14810-1 and 2 (2013; 2018), as structural panels of type P4 for use in dry conditions.

Particleboard Composite Made from Pinus and Eucalyptus Residues and Polystyrene Waste Partially Replacing the Castor Oil-Based Polyurethane as Binder

“…The MOR values for specimens M2, M3 and M4 were below acceptable levels. Though the MOE and MOR values for specimens M2, M3 and M4 are below the acceptable ABNT NBR 26 and ANSI values 34 , they are close to particleboard composite values reported in the literature 19,22 . Oliveira et al 22 studied the production of particleboards from EC wood and leather fibers using castor oil polyurethane adhesive.…”

Oliveira et al 22 studied the production of particleboards from EC wood and leather fibers using castor oil polyurethane adhesive. Authors investigated the effect of proportion of 10% (T1), 25% (T2) e 50% (T3) leather waste in relation to EC particles and 10% castor oil polyurethane adhesive.…”

“…In specimen M1, the TS value is better than that of the other specimens of particleboard composite with PS replacing the PUR, which can be attributed to the fact that PUR adhesives improve thickness swelling due to good interaction between wood particles 29 . According to Oliveira et al 22 , the MC value obtained here is acceptable for the production of medium density panels. The values of mixtures M1 and M2 on the MC are comparable to those reported by Oliveira et al 22 .…”

“…According to Oliveira et al 22 , the MC value obtained here is acceptable for the production of medium density panels. The values of mixtures M1 and M2 on the MC are comparable to those reported by Oliveira et al 22 . Other specimens (M3 and M4) showed average values that were similar to those of Martinez Lopez et al 20 .…”

“…Second, waste plastic can be used to bind wood particles for particleboard composites by using it as a binder. Researchers have demonstrated the potential of waste plastic as an alternative binder for the production of particleboard composites with wood waste, as well as an environmentally sound method of disposing of plastics [18][19][20][21][22] .…”
