“…La mayoría de los desechos tecnológicos no pasan por el sistema de reciclaje óptimo para el medio ambiente, lo que puede llegar a afectar a la salud de los humanos (Ilmasari et al, 2022). Teniendo en cuenta la reglamentación del sistema nacional del ambiente con las resoluciones emitidas que no se cumplen, destinadas a proteger el sistema ambiental a través las (TIC) para la prevención de la salud humana y el ambiente se deben tener en cuenta los siguientes requisitos sanitarios:…”

Las Tecnologías de la Información y la Comunicación (TIC), se han sistematizado a nivel mundial en cada uno de los ámbitos que se requiera y en el desempeño del usuario. Por ese motivo, se consideró una estrategia a implementar en los proyecto ambientales, siendo el objetivo de prevenir y mitigar la contaminación ambiental, con ayuda de los profesionales que usan una metodología cualitativa y un estudio descriptivo, utilizando un modelo de investigación y acción, participativa entre los profesionales, docentes y comunidad, Para hacer un muestrario de los datos, se utilizaron relatorías individuales, institucionales y evidenciando el desarrollo del estudio al proyecto, las problemática de malas acciones en el sistema ambientales, se basan en la contaminación y daños en la salud de los seres humanos.

“…In this condition, an acidogenic phase occurs where organic compounds begin to ferment rapidly with the help of microorganisms. Within the increment of landfill age, the BOD and COD concentration decreases until it reaches stable condition, called the maturation process through the methanogenic phase (11). It indicates that landfill leachate contains high organic matter from organic waste during the first year's operation.…”

Introduction: Landfill wastewater or leachate has unique characteristics. Several conventional methods need a few treatment tanks to cover the treatment process. A Sequencing Batch Reactor (SBR) is a biological treatment method that uses a single tank with few-cycle phases. This study aims to determine the potential of a Sequencing Batch Reactor (SBR) that can be used to treat landfill leachate. Methods: A Sequencing Batch Reactor (SBR) was used in this study. The characteristics of leachate served as the basis for the design of the SBR reactor. The synthetic leachate was used to create the reactor feed based on the actual landfill leachate compositions. The reactor's influent and effluent were analyzed based on a few parameter changes, such as Suspended Solid (SS), Chemical Oxygen Demand (COD), ammonia nitrogen (NH3-N), and Total Kjeldahl Nitrogen (TKN). Results and Discussion: While the experiment was running, 84% of SS were removed, 88% of COD were removed, a -28% efficiency rate for NH3-N removal, and a -172% efficiency rate for TKN removal. After the withdrawal phase, the supernatant showed promising results with 99% COD removal, 97% SS removal, and 65% TKN removal. Unfortunately, the removal of NH3-N reaches -130%. It indicates insufficient concentrations of MLSS and SRT, as well as the presence of a eutrophication process. Conclusion: SBR shows a promising result for leachate treatment. Few changes in the cycling process were needed for further study, so the treatment process becomes optimal to reach its full potential.

“…In the winter months, however, the risk of fire generally decreases due to the more humid and cold weather conditions. Leachate, another byproduct of open dumping, poses a threat to water sources due to its complex composition and inclusion of numerous pollutants [29]. Leachate transported by precipitation causes various environmental issues, including surface water, groundwater, and soil contamination [30,31].…”

Open dumping threatens the environment and public health by causing soil, water, and air pollution and precipitating the deterioration of the environmental balance. Therefore, sustainable waste management practices and compliance with environmental regulations are important to minimize these negative impacts. In this context, it is very important to identify the environmental damage inflicted by open dumping areas and to take measures to prevent this damage. Makkah is among the cities that still use open dumping for solid waste disposal. The rapid increase in this city’s population is generating large quantities of municipal solid waste (MSW), making it difficult to manage waste economically without harming the environment or public health. During Umrah and Hajj, the rate of MSW generation increases to an even greater degree. The sustainable management of MSW in holy cities is of great importance. This study aimed to investigate the environmental impact of the Kakia Open Dumping Site in Makkah on air quality, soil, and nearby groundwater wells. It also conducted analyses of essential elements (Ca, Mg, and Na), heavy metals (Pb, Cd, and Cr), and a metalloid (As) in leachate produced at the Kakia Open Dumpsite, enabling the development of management strategies. In addition, the correlations between the essential elements, the metalloid, and the heavy metals were also analyzed. The goal is not only to mitigate the negative effects of open dumping, but also to highlight the need to adopt sustainable management strategies for MSW in religiously significant cities like Makkah.
