    People's wrong habits when recycling Polyethylene Terephthalate plastic bottles ends up in environmental pollution, a plastic bottle recycling machine was implemented in Santo Domingo of the Tsáchilas, and using a Nelmor brand plastic bottle crusher, G1215M1 model, Polyethylene Terephthalate is processed.Crushed recycled PET percentage variations of 15 -20 –25 percent are made in the mixture with dimensions between 6mm -8mm -14mm and aggregate of 3mm -8mm -11mm. This concrete composite material plus the addition of crushed recycled PET are added in a manufactured mold from Artisan 1 that is a silicone elastomer. 45 veneers are manufactured and 4-point flexural tests are made, after 21 days of being manufactured according to INEN 2554:2011 norm, variates between 0,50125 and 1,59958 Megapascal. To the 45 veneers after 21 days of being manufactured, compression tests are made according to the INEN 1573:2010 norm and variates between 1.80700 and 4.31367 Megapascal. An optimization is performed through a surface response methodology using a statistical software, determining the optimal parametersfor veneers manufacturing, where the maximum percentage in the PET mix is of 15 percent with a dimension of 14mm and aggregate size of 6,95 mm. It is recommended in future investigations to make concrete veneers plus the addition of crushed recycled PET with a maximum percentage of 15 percent as a in the mixture, 14 mm dimension and 7 mm aggregate size, and to add a pigment in the mix to give color to the veneers.
