Manufacture of particleboard based on cement bag and castor oil polyurethane resin

• Discarded cement packaging recycling.
• Production of particulate panels from cement packaging with three densities (0.4; 0.5 and 0.6 g cm−3).
• Physical and mechanical properties of the cement bag-based panels.
• Particulate panels with 0.6 g cm−3 density meet physical–mechanical performance requirements recommended by ANSI (1999).

This study assesses the potential of cement packaging residues from building site wastes to produce particle boards. Panels with 0.4, 0.5 and 0.6 g cm−3 and 15% of castor resin content were produced and its chemical, physical, mechanical and microstructural were analyzed. The results revealed that the packages have a high cement content and low lignin pulp. Furthermore, the increase in density reduced the physical properties while enhanced mechanical properties, being the 0.6 g cm−3 particleboards the only formulation with potential to produce particulates. Thus, the packaging of cement becomes an option for the manufacture of particle board.
