Development of a Composite Material Based on Wood Waste Stabilized with Recycled Expanded Polystyrene

Environmental pollution is a whole world concern. One of the causes of that pollution is the proliferation of plastic waste. Among 
these wastes there is expanded polystyrene 
(EPS), mainly from packaging. This study 
aims to valorize EPS waste by developing a composite material from EPS waste 
and wood waste. For this purpose, a resin made of EPS has been elaborated by 
dissolving EPS in acetone. That resin was used as a binder in volume 
proportions of 15%, 20%, 25% and 30% to 
stabilize the samples. Some of them were thermoformed. The method of 
elaboration was based on a device consisting of an extruder for mixing the 
constituents, and a manual press for shaping and compacting the samples. 
Analyses show that the drying time depends on the composition of the mixture. 
Increasing the resin content leads to reduce water absorption and porosity of 
the samples; it also contributes to homogenize the internal structure of the 
samples. However, for the same resin contents, the thermoformed samples are 
less porous; they have more homogeneous 
internal structure; and absorb less water 
than non-thermoformed samples.
