Cutting fluids are one of the main pollutants in the machining processes of the metalworking industry, thus requiring special care in their environmental management. Early researches aimed at improving cutting fluids and devising more effective application methods focused on enhancing technological and economic aspects. However, in recent years, the efforts of researchers and manufacturers have concentrated on the development of environmentally friendly cutting fluids and new technologies aimed at the reduction or even the elimination of cutting fluids in order to satisfy increasingly strict environmental, public health and work safety regulations, as well as to align machining processes to an integrated system of quality, occupational safety and environmental management. The objective of this work is to find examples and contribute toward the search for viable solutions to minimize the environmental impacts caused by the use and disposal of cutting fluids, correlating these solutions to good environmental practices and to the 3Rs principle. This work involved a comprehensive bibliographic review focusing on the identification of studies that show the environmental concern of the metalworking industry in the search for opportunities to adopt good environmental practices in the management of cutting fluids. It was found that, despite the development of less environmentally harmful cutting fluids and of methods for the application of increasingly small quantities, this basic product still requires environmentally-based management for its correct use.

La economía circular como parte de la sostenibilidad en el sector hotelero y su posible aplicación en el Perú / The circular economy as part of sustainability in the hotel sector and its possible application in Peru

Berrú Potozén, Manuel Orlando, Grabielli Velasquez, Fiorella 15 November 2020 (has links)
Las industrias colaboran con la degradación gradual del planeta y la industria hotelera no está exenta de ello. Por ello, se observan algunos cambios de actitud y políticas por parte del sector hotelero con respecto a su impacto ambiental; sin embargo, aún no existe un plan específico de acción que dirija a los hoteles a desarrollar una gestión sostenible. Actualmente, el sector hotelero mantiene un modelo económico lineal basado en usar y desechar; el cual se plantea reemplazar por uno circular que permite utilizar y optimizar los recursos evitando dejar residuos y/o desperdiciarlos aportando valor a la empresa y a su entorno para poder alcanzar la sostenibilidad. Esta investigación busca detallar a profundidad la realidad acerca del enfoque de la economía circular y su aplicación en la hotelería a nivel mundial para su posible implementación en los hoteles en Perú. Se empleó la metodología de revisión bibliográfica descriptiva y evaluativa partiendo de fuentes académicas como artículos científicos, tesis, entre otros; teniendo en cuenta las fechas de publicación del 2015 al 2020 con respecto a la economía circular y su aplicación en el sector hotelero a nivel mundial. A partir de ello se identifica que el sector hotelero mundial actualmente no utiliza el enfoque de la economía circular y en el sector hotelero peruano aún no se realiza mucha investigación sobre esta temática por lo cual se requiere ampliarla y realizar la respectiva experimentación que proporcione argumentos a favor o en contra de implementar la economía circular. / Industries collaborate with the gradual degradation of the planet and the hotel industry is not exempt from it. Therefore, there are some changes in attitude and policies on the part of the hotel sector regarding its environmental impact; however, there is still no specific action plan that directs hotels to develop sustainable management. Currently, the hotel sector maintains a linear economic model based on use and discard; which is proposed to replace by a circular one that allows to use and optimize resources avoiding leaving waste and / or wasting them, adding value to the company and its environment in order to achieve sustainability. This research seeks to detail a depth of reality about the circular economy approach and its application in the hotel industry worldwide for its possible implementation in hotels in Peru. The descriptive and evaluative bibliographic review methodology was used based on academic sources such as scientific articles, theses, among others; considering the publication dates from 2015 to 2020 regarding the circular economy and its application in the hotel sector worldwide. Based on this, it is identified that the world hotel sector does not currently use the circular economy approach and in the Peruvian hotel sector much research is not done on this issue yet, so it is necessary to expand it and carry out the respective experimentation that provides arguments to favor or against implementing the circular economy. / Trabajo de investigación

Inga Ortiz, Gabriel Ruben, Seragaki Collazos, Carolina Hiromi 27 June 2021 (has links)
La presente investigación tiene como principal objetivo el de realizar un análisis de la aplicación de los criterios de sostenibilidad ambiental y su relación con la satisfacción de los clientes de servicios hoteleros, por consiguiente, este estudio integrará estas dos variables para que se pueda contar con un estudio completo del tema que integre el conocimiento existente. El método utilizado fue el de revisión de literatura con enfoque integrador, se realizó una búsqueda y análisis de literatura académica tanto el idioma inglés como español, como artículos científicos, libros y tesis, con la finalidad de tener diferentes argumentos y puntos de vista sobre las variables de estudio. Además, todas las fuentes incluidas son preferentemente de los últimos cinco años entre el 2015 al 2021.En los últimos años, dentro del sector hotelero cada vez es más importante generar diferenciación frente a la competencia, por lo que la sostenibilidad se ha convertido en un punto clave para tener una mejor reputación, no sólo en términos sociales sino también económicos y ambientales. Se puede establecer que la satisfacción por parte de los clientes de servicios hoteleros, se ve impactada de manera positiva por la aplicación de criterios de sostenibilidad y, además, cada día más hoteles los están implementado; sin embargo, aún existe una brecha entre la teoría y la práctica. / The main objective of this research is to carry out an analysis of the application of environmental sustainability criteria and its relationship with the satisfaction of hotel service customers, therefore, this study will combine these two variables so that it can be exposed to a complete study of the subject that integrates existing knowledge.The method used was the literature review with an integrative approach, the search and analysis of academic literature was carried out in both the English and Spanish languages, as well as scientific articles, books and theses, in order to have different arguments and points of view on the study of these variables. In addition, all sources included are preferably from the last five years between 2015 to 2021. In recent years, within the hotel sector it is increasingly important to create a differentiation from the competition, so sustainability has become a key point to have a better reputation, not only in social terms but also in economic and environmental terms. It can be established that the satisfaction of hotel service clients is positively impacted by the application of sustainability criteria and also, more and more hotels are implementing them; however, there is still a gap between theory and practice. / Trabajo de investigación

Medidas de responsabilidad ambiental en la hotelería y su influencia en la satisfacción de los clientes / Measures of environmental responsibility in the hotel industry and its influence on customer satisfaction

Vasquez Flores, July, Velasque Parco, Andrea Aracely 28 November 2021 (has links)
El presente trabajo se ha desarrollado debido a la preocupación que existe ante los impactos que el sector hotelero genera sobre el medio ambiente y cómo mitigan estos impactos con acciones que ayudan a revertir el problema. Por tanto, el presente estudio tuvo como objetivo general investigar las medidas de responsabilidad ambiental implementadas en el sector hotelero y su influencia en la satisfacción de los clientes. Esta investigación empleó la metodología de revisión de literatura con enfoque integrador, ya que las variables planteadas fueron analizadas y evaluadas para concluir el tema de investigación. De ese modo se determinó que las acciones ambientales de los hoteles influyen en el comportamiento de los consumidores que apuestan por estas nuevas tendencias; estos se hospedan en hoteles orientados a las mejores prácticas ambientales donde priorizan el cuidado del medio ambiente para el crecimiento de sus operaciones. Asimismo, las empresas hoteleras se encuentran aplicando medidas de responsabilidad ambiental en sus actividades para mejorar la calidad del servicio y favorecer la mejora de su entorno ambiental. Sin embargo, aún existe escasa información y evidencia de cuáles son las medidas de responsabilidad ambiental que han demostrado tener mayor influencia en la satisfacción de los huéspedes. En tal sentido, este estudio brinda información sobre la importancia de las prácticas ecológicas de la hotelería y su efecto en los clientes. / The general objective of this study is to investigate the environmental responsibility measures implemented in the hotel sector and their influence on customer satisfaction. This research will use the literature review methodology with an integrative approach since the proposed variables will be analyzed and evaluated to conclude the research topic. This work has been developed due to the concern that exists about the impacts that the hotel sector generates on the environment and how to mitigate these impacts with actions that help to reverse the problem. Therefore, it was determined that environmental issues influence the behavior of consumers who bet on these new trends, they stay in hotels oriented to the best environmental practices where they prioritize caring for the environment for the growth of their operations. Likewise, hotel companies are applying environmental responsibility measures in their activities to improve the quality of service and favor the improvement of their environmental environment. However, there is still little information and evidence of which are the environmental responsibility measures that have been shown to have the greatest influence on guest satisfaction. In this sense, this study provides information on the importance of green hotel practices and their effect on customers. / Trabajo de investigación
