Influence of the Density in Binderless Particleboards Made from Sorghum

In order to fight climate change and decouple economic growth from material use, valorization of waste will be fundamental. Sorghum is one the most important summer crops in world. The non-edible parts plant, stalks leaves are left over must disposed of. This work proposes use sorghum particles as a raw manufacture boards analyze influence its density. Particles were sprayed with 10% wt water placed hot press at 2.1 MPa 110 °C for 30 min. Eight types panels produced densities ranging 950 kg/m3 1250 kg/m3. results indicated that absorption (WA), modulus rupture (MOR), elasticity (MOE) internal bounding strength (IB) depended on With higher densities, particleboards showed better physical mechanical behavior. study demonstrates it technically possible adhesive-free residues comply European standards can used general applications. these could beneficial fighting minimizing natural wood.
