“…In thermoforming, agglomerates are obtained under the following operating conditions: heating time 60 min, pressure 4 tons of axial compression at 180°C; then the agglomerate is cooled to room temperature and removed. The described procedure has already been previously reported (Enríquez Pérez, Rosales Davalos, López Ramirez, & Castrejon Sanchez, 2017).…”

Sustainability makes the final use of waste reconsider, if it is possible to give it a new use and thus contribute to the planet. Therefore, in this work the physical and mechanical properties of particulate agglomerates from the recycling of multilayer containers (EM) and powdered milk (EL) are evaluated, the w/w ratio was varied. Agglomerates with a homogeneous matrix are obtained, hard to the touch, light, they can be cut, drilled, they are fireproof, they all have a prolonged elastic zone, when subjected to a load they do not show rupture, they support loads of 12 MPa. As the amount of EL increases, the density of the agglomerate increases and the apparent density decreases due to the compressibility of the materials, which contributes to reducing the degree of hygroscopicity. There is no relationship between the density and the properties of the agglomerates. The material that complies with the NMX-C-013-1978, ASTM D 1037-12 and NMX-C-036-ONNCCE-2013 standards, is the one with a p/p ratio of 70:30 (A6), it can be used in construction as a false wall; both outdoors and indoors. The other agglomerates could be used as catalytic supports for the degradation of dyes; because they show dimensional stability when in prolonged contact with water.

In the present work, synthesis and characterization of a Hydroxyapatite (HAp)/Zinc Oxide (ZnO)-based composite in proposed. The Egg-shell (ES) is used as Hydroxyapatite source. We pretend to take advantage of photocatalytic activity of both materials. This composite can be applied in mineralization of organic dyes in waste water. The methodology followed for the preparation of the composite was carry out a Sol-gel of precursor ZnO synthesis, after, it was mixed with the previously synthesized Hydroxyapatite and calcinated at 650 °C. Later, all materials were characterized using of Raman Spectroscopy and X-Ray Diffraction (XRD), to determine the crystalline phases present; Scanning Electron Microscopy (SEM) to obtain the morphology; Energy Dispersive Spectroscopy (EDS) to determine elemental composition. It was possible to synthesize a HAp/ZnO composite, the characterization showed that it was obtained a composite with carbonated hydroxyapatite Type B. It is important to highlight that the method of composite synthesis, it was not a homogeneous synthesis, it is proposed to look for another impregnation method.
