This paper presents a study that aimed to determine the mechanism of a process for Cr(VI) removal from aqueous solutions, using compost of carnation crop residues as the adsorbent. We assessed whether the microbiota present in the absorbent material affected the removal of Cr(VI) using respirometric measurements and evaluating the removal capacity using sterilized and not sterilized compost. Additionally, the compost was analysed before and after carrying out the Cr(VI) removal process, by quantification of the acidic functional groups and kinetic monitoring of pH, conductivity and redox potential difference. The results showed that, under the conditions used, the microorganisms present in the compost did not affect the process of Cr(VI) removal and that the mechanism can be described by an adsorption model coupled to the reduction, were this adsorption is mainly done on the acidic funct...

A line balancing model for a tempered glass processing company was developed in this study, aimed at demonstrating how its implementation helps to improve productivity. The model is based on the development of the five steps of the theory of constraints (TOC): identify the constraint, exploit the constraint, subordinate everything to the constraint, elevate the constraint, and check if there is a new constraint. Once the restriction was identified, it was exploited using improvement actions, such as the detection and elimination of mudas (wastes), and the application of the 5S methodology until a production capacity in line with demand was achieved. As economic investments had to be made, a table with a cost structure before and after the implementation of the model was prepared in order to calculate the return on investment (ROI) value to determine that the investment made promoted the ...

This research will serve as a precedent for other studies that aim to improve the production processes of textile and apparel companies by proposing a preventive solution for excess fabric waste that results from the production process. The study will also provide insights into reducing the amount of excess fabric waste in the marking and cutting areas via the manufacture of additional clothing items and accessories. Consequently, by efficiently allocating resources to make optimal use of seasonal material, costs can be reduced, ultimately leading to improved profitability for the textile knitwear company.

In this study, waste hairs of the enzymatic unhairing process (PPE) of tannery were used as adsorbents to remove lead of a solution. Waste hairs were treated with acid hydrolysis and used in the type batch adsorption experiments, to be examined the effect of pH on the adsorption and also to investigate the mechanism of adsorption for which studies adsorption isotherms and the adsorption kinetics of Pb (II) were performed on treated hairs. The results showed that adsorption of Pb (II) was pH dependent with the optimum pH of 7. Isotherm studies showed that experimental data match the pattern of the Langmuir isotherm for the case of treated hairs of the enzymatic unhairing process (PTPE). The maximum adsorption capacity was 321.20 mg Pb (II)/g of bioadsobent (PTPE). The kinetic studies showed that the reaction model of pseudo-second order best describes the adsorption process. Finally, the ...

El objetivo de esta tesis es la caracterización del funcionamiento hidrogeológico de la unidad minera Santa Rosa (UMSR). Para lograrlo se ha empleado información de cartografía geológica, hidrogeológica, datos mineros y diferentes mapas temáticos, así como mapas derivados obtenidos con técnicas geomáticas y modelos numéricos. En diferentes campañas de campo fueron inventariados 270 puntos de agua, cuatro tajos abiertos, dos tipos de residuos mineros en un área de 878 Ha. De acuerdo con los resultados en la UMSR se diferencian dos unidades acuíferas de importancia: acuífero fisurado formación Chimú y acuífero cárstico formación Inca Chulec. La cartografía geológica y el mapa de alineamientos muestran que el área de la UMSR está cortada por diferentes tipos de fallas y fracturas en 4 direcciones principales. Los tajos abiertos y las zonas fracturadas controlan la re...

Objective: To determine the characteristics in relation to waste treatment in textile industry in San Juan de Lurigancho. Materials and methods: It was considered a non-experimental, basic and descriptive study. The sample was composed of ten establishments in textile industry in San Juan de Lurigancho, selected by the use of the non-probability sampling.

Remote sensing played a crucial role in the study by facilitating the collection of essential data for monitoring and creating interactive maps detailing the locations of open-air municipal solid waste landfills in the Tarata Province. This approach allowed for a comprehensive understanding of the distribution and characteristics of the landfills. Using ArcMap software, a comparison was conducted between the 2023 and 2016 data. The process involved the examination of satellite images and georeferenced records. Additionally, a set of orthophotos captured by a drone was integrated into the study. These analyses resulted in the identification of four landfills. The largest one, covering an area of 1568.02 m2, was found in Ticaco, highlighting the magnitude of the waste disposal issue in this area. Conversely, the smallest one, covering an area of 378 m2, was discovered in Estique. Furthermo...

Solid waste management is one of the main environmental challenges in cities around the world due to factors such as population growth and consumption habits. One of the main tools for the design of waste management projects is the estimation of per capita generation, however, the traditional method to obtain this information demands a lot of effort and time, therefore this research proposes an alternative approach to estimate per capita generation based on socioeconomic factors. For this purpose, socioeconomic demographic information and information on the per capita generation of solid waste of 50 families was collected, subsequently the variables that have significant influence were determined from the correlation coefficient ρ of Spearman for numerical variables and an ANOVA for categorical variables with an acceptance threshold of 0.4 and 0.05 respectively. The selected variables w...

The growing energy demand and per-capita consumption create environmental problems due to the generation of organic and inorganic waste. At present, it has been established to identify the ideal management conditions to mitigate these environmental problems and achieve sustainable development, with the implementation of waste recovery and recycling systems. In this research work, the scope of consumption and waste generation of the San José campus of the Catholic University of Santa María in Arequipa-Peru are studied, developing a waste recovery and identification system. The generation of solid waste was 0.00487 Kg / person-day, with a total daily generation of 73.78 Kg / day. The composition of common solid waste was composed of 17.28% of organic matter, being the component with the highest representativeness, the waste paper represented 12.13%, the components of plastic waste were 9...
