The use of clean technologies for the treatment of textile effluents is essential to achieve a significant contribution by the textile industry, environmental treatment of them. According to the literature, the dyes used in textile industry are hardly degradable and have strong opposition to biological treatments are subjected to appropriate wastewater. At lower concentrations of hydrogen peroxide (oxygenated water) leads to better dye fading. It also shows that lower concentrations of titanium dioxide system response to the degradation of color, is better, this could be because that lower concentrations of titanium dioxide, hydroxyl radical formation is lower, thus increasing its efficiency the process. The optimum time for color degradation is 2 h and the concentration of titanium dioxide to achieve this time was 50 ppm

This work, in synthesis, is about the exercise of good corporate management practice. The systematic nature of administration, alignment, strategy and skills in the metal mining sector in peru, influence of the Resource and Capacity development theory. We also deal with the value chain, competitive advantages, strategies and skills in the metal mining activity and mining strata. From the development of these points, we set up as conclusions that all formal, legal or illegal strata coexist somehow because the legal ones can export all production. On the other hand, it is required a strategy, promotion, planning and specialized professional leadership in this industry. At the same time, it is required that the government support all this effort and the centers of technical and vocational training in geology, mining, metallurgy, chemistry and related competences define and design formation ...

There is currently a growing interest in the natural spaces located on the periphery of cities, due to the environmental, social and economic benefits that they provide to citizens. This paper aims to evaluate the relationship between natural spaces and territorial planning instruments, considering the theoretical and methodological contributions developed from the ecological infrastructure.The methodology combines qualitative and quantitative tools, the qualitative were used for the analysis of the types and levels of use and also the natural spaces degradation, in addition, to determine the relevance of territorial planning instruments and the incorporation of the natural spaces in these. The quantitative variables were used to measure the relationship between variables, using a binary logistic regression. A total of 29 natural spaces and 13 planning instruments were registered and ana...

Existe un creciente interés por los espacios naturales ubicados en la periferia de las ciudades, debido a los beneficios medioambientales, sociales y económicos que éstos proveen a los ciudadanos. Este trabajo busca evaluar la relación entre los espacios naturales y los instrumentos de planificación territorial, tomando los aportes teóricos y metodológicos desarrollados desde la infraestructura ecológica.La metodología combina herramientas cualitativas y cuantitativas; las cualitativas se utilizaron para el análisis de los tipos y niveles de uso y degradación de los espacios naturales, asimismo, para determinar la pertinencia de los instrumentos de planificación territorial y la incorporación de los espacios naturales en éstos; las cuantitativas se utilizaron para medir la relación entre variables, específicamente se utilizó una regresión logística binaria. Se registra...

Based on the problems of the industrial sector, on the commercialization of plastics, which has been affected by the implementation of the law that restricts the use and commercialization of single-use plastics through the implementation of Law No. 30884 – “Law that regulates single-use plastic and disposable containers or containers”; This article proposed the implementation of a new production model based on Lean manufacturing with a biotechnological approach in a Mype of the plastic industry. For this reason, a research method transversal to the supply chain with a sustainable approach through the application of biotechnology was chosen. This technique uses natural resources to produce substitute products for single-use plastics and achieve a sustainable product. The methodology used was non-experimental and descriptive, developing a proposal for a sustainable alternative in the...

In mass production, the carbon nitrogen (C: N) ratio affects the growth and production of conidia. The objective was to evaluate B. bassiana and M. anisopliaenativos in solid substrates rice (Oryza sativa L.) and corn (Zea mays L.) enriched with nutritional supplements, molasses (source-carbon) in concentration (2.5-5.0 g ), amaranth and soybean meals, milk powder and yeast (nitrogen sources) of concentration (0.25-0.50 g), compared with controls. The C: N ratio was 10: 1. The experimental design was Categorical Multi-Factorial and the technique, observation. The mass production of fungi was solid fermentation in 40 treatments with 3 repetitions; the count of conidia in the Neubauer chamber; and, the analysis of results with Statgraphics Plus-Ver.5.1, IBM-SPPS-Ver.22 and Excel-2013. The best production of B. bassiana in rice was T13 (molasses-2.5 and milk-0.25) g with an average of 1.89 ...

This study arises as a result of the problem in the location of solid waste final disposal infrastructures (Landfill) where various analysis criteria are taken into consideration following the provisions of DL Regulation N° 1278 Comprehensive Waste Management Law Solid DS N° 014-2017-MINAM. The optimal location analysis was carried out using the Multicriteria Spatial Analysis (AEMC) processes as well as the hierarchical analysis process (AHP) applying it in a Geographic Information System (ArcGis). The purpose of the investigation was to locate the appropriate areas for the final disposal of solid waste in the city of Cerro de Pasco. The results present the consideration of 6 alternative locations for the sanitary landfill, all of them between 3 and 4.13 km away from the city, under physical, environmental, socioeconomic and legal criteria. It is concluded that geographic information s...

Environmental education is an effective tool to apply sustainable production techniques. The objective of this research was to apply environmental education strategies to reduce the use of agrochemicals in the Balsa en Medio community (Ecuador). Using Likert-type scales, a diagnosis was made of the level of knowledge and environmental behavior of the community members. Afterwards, the training plan was implemented applying environmental strategies on the preparation and application of compost, bioles, bioinsecticides and biopreparations with efficient microorganisms in seasonal crops. Finally, the final environmental knowledge and behavior of the participants was evaluated. The results of the diagnosis revealed that 100% of the participants presented a deficient environmental knowledge, while 98% of participants showed inappropriate environmental behavior. After applying an environmental...
