Non-hazardous waste generated in Metropolitan Lima and Callao is transported to the Modelo Callao landfill for safe disposal. The accumulation of waste constitutes a significant source of fungal particles released into the atmosphere, posing a potential health risk to nearby populations. The aim of this research was to evaluate the concentration of outdoor fungal particles, considering environmental conditions (temperature, relative humidity, wind speed, and direction) during summer and winter seasons in the 18 de octubre settlement and Chill´on Avenue, areas located in the vicinity of the Modelo Callao Landfill in Ventanilla during 2022. The gravitational method was used for sampling. The highest concentrations were detected at 150 and 200 m from the landfill, where a kindergarten and a local park are located. Fifteen fungal genera were identified in both seasons. The predominant fungi...

La presente investigación elabora un estudio de prefactibilidad para la producción y venta de biodiesel a partir de los residuos de aceites y grasas obtenidos de las plantas de tratamientos de aguas residuales de Lima Metropolitana y Callao. La producción de biodiesel a partir de aceites y grasas recuperadas de las plantas de tratamiento de aguas residuales les da un valor a estos residuos y promueve la economía circular, ya que estos residuos no son aprovechados y suelen terminar en los rellenos sanitarios de seguridad como parte de su disposición final porque son altamente contaminantes.
