The research was conducted in an industrial plant for the production of fishmeal and fish oillocated in Puerto Malabrigo Rázuri district, Ascope province La Libertad Region(coordinates: 7 o 41 '40.54 "south latitude and 79 o 25' 58.73" W), for three production periods: from November 2011 to January 2012, from April to July 2012 and November 2012 to January 2013.The dates were obtained from the monitoring plan of pumping water, then recovery efficiency obtained using the methodology Otárola thus significant differences between recovery periods for both fat as a percentage suspended solids and recovery efficiency of the system from pumping water ingress to the emitter of 96, 99 and 98 for fat, 97, 98 and 99 for suspended solids, thus it is concluded that the recovery efficiency of suspended solids fat and water is pumped upward over the production period.

The district of Trujillo faces a public health issue due to the emergence of critical points of solid waste accumulation, which increases the risk of disease transmission, degrades the urban environment, and negatively affects the population’s perception of safety and well-being. The objective of this study is to analyze the spatial patterns of critical point generation in Trujillo and their relationship with socio-environmental factors that may explain their distribution. A quantitative approach was employed, specifically a descriptive-correlational, non-experimental design, combining remote sensing techniques, spatial analysis through Geographic Information Systems (GIS), and fieldwork based on household surveys. The study targeted residents over 18 years of age in the district of Trujillo, whose households were located within a 30-meter radius of the identified critical points. A to...
