Some countries with tropical climate produce a great variety of lignocellulosic waste from crops planted in small areas and their urban areas produce a great amount of waste Tetra Pak packages. A possible solution is to incorporate this waste in particleboards. The main objective of this work is to determine the relation in a mixture of particles of empty fruit bunch of Elaeis guineensis (EFB), pineapple (Ananas comosus) leaves (PL), and Tetra Pak packages (TP) with 3 kinds of wood from forest plantations (Gmelina arborea, Tectona grandis and Cupressus lusitanica). The proportions 50:50, 70:30, and 90:10 (residue:wood) with adhesive at 6, 8, and 10% (weight/weight) were tested for density and resistance regarding internal bond strength. And these values were compared with particle board fabricated with 100% of wood. The results showed that when the EFB and PL proportion decreases, the IB values increased the 90:10 mixture with 10% adhesive being the one with the highest internal bond. But for matrixes with TP, the highest IB value comes with a 50:50 proportion with 10% adhesive.
