Currently, the construction industry is one of the main causes of pollution worldwide. Prepare an ecological block from waste materials such as construction debris and give them a second use and natural additives such as nopal mucilage, nejayote and molasses to combat humidity. The quasi-experimental methodology of a quantitative, descriptive type. The prototype of block 1 is the one with the highest axial compression resistance with 72 kg/cm2 and can be used as a load-bearing concrete block and its absorption percentage is under 7%, which shows that waterproof materials such as nopal mucilage and nejayote. In the second prototype with the addition of sawdust and molasses, the resistance to axial compression was not achieved, since it only reached 11 kg/cm2, but it was waterproof with a percentage of 12%.

Generate electricity through the photosynthesis of the water lily; releasing electrons at their roots, to be collected by the anode (copper wire) and cathode (metallic foil) conductors, to transport them through copper conductors and be able to use them, in light energy, in a 3-volt led. Plastic containers on average have a higher voltage, compared to metal containers, on average they reached 0.747 volts, R6 was the one with the highest voltage production and the lowest 0.518 volts on average was R4. The voltage produced by metal containers, which did not reach the maximum values of plastic containers, the highest average is R7, with a voltage of 0.576 volts and the lowest of all averages is 0.216 volts R10, On 09/17/2019 at 4:45 PM, the highest average voltage of 7.11 volts was recorded.

One way in which universities measure the level of competencies achieved or identify the level of academic knowledge and skills of graduates is through the General Examination for Undergraduate Exit (EGEL). Know the level of performance of the General Examination for the Graduate Degree in Architecture (EGEL-ARQUI) of the students before and during the pandemic. The generation that obtained the highest average score in the different areas is that of 2019 with 946 points and two students achieved satisfactory performance, followed by that of 2020 with 928 points with one student in satisfactory performance and the lowest in score. It is the generation of the year 2018 with 898 points, satisfactory performances were not achieved. The area with the lowest score on average was presented in the Architectural Project with 800 points on average of the three generations, being the year 2020 (COVID-19 pandemic), the lowest average with 760 points.
