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.
