Advances in single-use packaging and container technology are generating an indiscriminate increase in urban solid waste, which is on the rise. In 2020, Mexico achieved a recycling rate of around 30% in Tetra Pak packages; although this percentage is encouraging, most waste still needs to be reincorporated into any cycle. On the other hand, one of the most alarming impacts of the construction industry is the extraction of raw materials and their potential greenhouse gas emissions. In order to associate these two environmental issues, this work aimed to evaluate the physical-mechanical properties of concrete added to Tetra Pak waste. Specimens of 10 cm in diameter and 20 cm in height were studied. For the mixtures, weight contents of 2%, 4%, 6%, and 8% of 5 mm x 3 cm fibers were used, which were tested in the fresh and hardened state at 14 and 28 days of curing. The results indicated that as the fiber content increases, the mechanical properties of the specimens decrease, so its use for structural purposes should be re-evaluated with other techniques, such as gamma irradiation. It is recommended to use this material in masonry pieces for non-structural purposes and to characterize its thermal and acoustic properties.
