Abstract: Although several reports can be found in the literature about the recycling of plasticmaterials, only a few focus on recovering and molding them in a new process. Plasticmaterial blends can be fabricated using several techniques, which allows the molding of acompound adaptable to each needed performance. This fact favors the recycling byallowing the use of mixed wastes without major processes, avoiding expensive treatments.This research work analyzes the mechanical properties of a material conformedby 100% recycled plastics: polyethylene terephthalate and low-/high-density polyethylenewithout previous separation or washing and drying pretreatments. Its macro andmicroscopic structure was studied and described, and formulations of different compoundrates were analyzed. Mechanical resistance was around 60% of a material composedof virgin materials in compressive, flexural, and tensile strength tests. Its potentialapplication to building components manufacture is analyzed.
