This article addresses the problem that is being generated by the use of mouth covers, gloves and masks used as protection against covid 19. After more than a year in a pandemic, the demand and waste of these protective implements has increased exponentially, which is why it is necessary to dispose of these sanitary wastes safely, to guarantee community health and the integrity of the environment. On the contrary, improper handling of such a volume of these wastes can have a rebound effect, both on people's health and on the environment. The objective of the research is to properly dispose of these wastes, through the use of special containers for this type of waste, as well as the proposal with the government and companies that use ovens for the production of their products, so that with the necessary measures They could dispose of this type of waste as raw material for their furnaces, since these companies have standards that they comply with to regulate the Co2 emissions that they emit into the environment, and thus minimize the impact that these wastes bring to the environment.

Currently, the interest and the need to innovate new materials through the use of waste materials has grown, which meet similar or improved physical, chemical and mechanical characteristics of the materials they will replace. During the present investigation, Multilayer Containers (EM) and Low Density Polyethylene (LDPE) were collected, particulate agglomerates with different proportions were obtained, the apparent density, water absorption, mass, volume, heat behavior, angle were determined. contact, machining and compression tests. With the objective of evaluating the proportions p / p in the properties. The advantage of the material obtained is that they do not generate waste and are 100% recyclable. The 90:10 ratio is the one that could be used in the construction industry as false walls, with a modulus of rupture of 52.7 N / mm2 and a compressive stress of 32.9 MP, because it can be machined without altering its characteristics. -physical houses; While the 85:15 and 80:20 proportions, since they cannot be machined, could be used as a floating support with a photocatalyst catalyst, due to the fact that these agglomerates have dimensional stability when in contact with water.

At present, drought seasons are longer as a result of global warming, which has generated scarcity and rationing of water, these conditions become the main problem in towns far from urban areas and with little infrastructure. Mexico, with 653 aquifers throughout its territory, 106 are overexploited due to agricultural, mining, industrial and urban activities, which projects a possible depletion and contamination of its vital liquid to the country. For this reason, in order to contribute to a solution to the problem of water scarcity, when applying a control system to the technology used by Peltier cells, a moderate flow of water is generated, since it condenses the particles of water suspended in the air. In this way, a prototype was developed in which a Peltier cell arrangement is implemented to obtain as much water as possible under environmental factors, such as humidity and temperature, as well as an analysis of efficiency, cost and viability with a commercial generator system of water with similar capacities.
