This article aims to provide a new concept of industrial processes, the so-called sustainable industrial processes that are used in industrial plants and competitive companies responsible for developing chemicals. These innovative processes should incorporate in its design stages that are efficient, producing less waste and scrap, not pollute the environment, using substances which are safe, and the products and by-products produced by them. These processes must be safe, both internally (for workers) and externally (for communities and ecosystems) and must contribute to sustainable development, ensuring the efficient use of natural resources and promoting the use of renewable resources. An example is the production cellulose pulp that is produced throughout Latin America (Brazil, Argentina and Uruguay), but a sustainable industrial process can be developed nationally.

Integral management of chemical wastes generated in industrial activitiesThe integral management of chemical wastes allows to d iminish the amount of generated wastes, to reutilize wastes so as to diminish their danger, and to make safe use of the final disposition of those wastes that cannot be reduced. Here we present the principies of chemical wastes management, the analysis of the service I ife of a waste and diverse treatment options (physical, chemical, thermal and biological) for its final disposition

A landfill is an infrastructure used for the final disposal of non-recyclable wastes. lt is possible to calculate its usetul lifetime by taking into account three cases; the first one assumes that there is no growth in the population, the second that the population doubles every given number of years and the third that the population grows exponentially. The following article presents all three cases in detail; as well as examples to determine the useful lifetime of the landfill (in years).

El método TRIZ, plantea que la mayoría de los sistemas diseñados con la finalidad de solucionar problemas, evolucionan siguiendo pautas predeterminadas, en vez que de una forma aleatoria. Estas pautas se pueden conocer a través del estudio de la trayectoria del sistema (trayectoria tecnológica); es decir, de su evolución en el tiempo, tomando como referencia el conocimiento adquirido. Esto permite que estas pautas se puedan utilizar para acelerar la evolución de otros sistemas. Se pueden encontrar formas comunes de resolver problemas o de mejorar un sistema, mediante el análisis histórico de patentes, esto permite que el conocimiento incorporado en una innovación pueda ser recogido y transferido. El objetivo del presente documento es demostrar la aplicabilidad del método TRIZ para la solución de problemas tecnológicos que se presentan en procesos industriales, para lo cual s...

The educative institutions and the companies of services that count on compatible laboratories of chemistry, in order to bring chemical experiences of laboratory or analyses as a part of a service to third, require, like the productive companies, of an appropriate management and handling of their chemical wastes.

El artículo tiene como objetivo fundamental proponer un diseño efectivo para el tratamiento óptimo de aguas grises claras, las cuales siguen la clasificación de los diferentes tipos de aguas residuales como resultado de la prestación de un servicio tanto a nivel doméstico, como industrial. Según el grado de impurezas contenidas en dichas aguas residuales, se clasifican por ese orden en aguas negras, aguas grises obscuras y aguas grises claras. En el diseño propuesto, se hace una diferenciación de los desagües, que permiten tratar in situ a las aguas grises recolectadas en los servicios higiénicos situados en el quinto piso de la Facultad de Química e Ingeniería Química de la Universidad Nacional Mayor de San Marcos. En la investigación se realizó la recolección, cuantificación, caracterización y tratamiento de las aguas grises, para un caudal promedio de 26.12 L/h (2.0...
