The objective of this paper is to propose a set of environmental indicators to measure water, energy and solid waste management for the organizational environment with focus on the teaching area, in this case, the Federal Institute of Education, Science and Technology of Rio Grande do Norte. In the institutional context in which the work is inserted, it is considered that this effort will provide the institution involved with the implementation of an appropriate tool to measure the environmental dimension of the axes involved, thus having the necessary skills to address, improve, instigate the theme of preservation of natural resources. The following stand out as results: a consistent set of result indicators to measure the proposed variables, aiming at the effective implementation and continuous improvement in the process of monitoring the environmental performance of the Institution.

This paper deals with the environmental and process diagnosis with a view to the implementation of the Cleaner Production environmental management tool in 2016 and 2017, in the quarry of the company Granorte - Mining of Marbles and Granites of Rio Grande do Norte, located in the area rural area of Parelhas-RN. The objective of this work was to diagnose the situation of solid waste generation in the mining fronts. The diagnosis for implementation of Cleaner Production techniques for ornamental rock mining followed the methodology of SENAI's National Center for Clean Technologies. The programmed activities were developed and organized involving bibliographic research, data mining of the mining process, field visit and laboratory work. The bibliographic search was performed through consultation in databases, magazines, journals and books. Two residue samples were collected for chemical analysis of the X-ray Fluorescence type. These analyzes identified small traces of rare earth elements, as well as the presence of silicon oxide in percentages that can be exploited. The amount of rock and soil handled during the study period was 17,487.00 tons, of which 11,768.75 tons were disposed of as waste piles, and 5,718.25 tons as product in the form of blocks. The study identified that 99.97% by mass of solid residues generated on the mining fronts are from rock fragments. However, the results also demonstrated that Cleaner Production techniques such as process modifications and the application of good operating practices. [ABSTRACT FROM AUTHOR]

Despite the relevance, discussions and dissemination of information, the execution of measures to cope with desertification have barely been implemented. Therefore, this paper aims to present a synthesis of information on the environmental aspects of the areas susceptible to desertification in the Brazilian semi-arid region and to present the socio-environmental characteristics most directly related to desertification in the Seridó do Rio Grande do Norte and Paraíba. For that, Where it was consulted books, institutional documents, specialized periodicals, scientific articles and access to databases, through expressions in Portuguese that related to desertification, areas susceptible to desertification, center of desertification and desertification center of Seridó. It was found that there are 1,340,000 km² of ASD in Brazil, which occur mostly in the semiarid region. In the ASD, prevailing rainfall indices below 800 mm, with high potential evapotranspiration. The soils, which have long been used by humans and are moderately to highly sensitive to erosion, have the following levels of degradation: 40.80% (moderate), 27.68% (high) and 5.86% (very high). The Caatinga is the predominate biome, and 46.4% of this territory has been influenced by humans. In Seridó RN / PB, as implications of the predominant economic characteristics, characterized by intense extraction of firewood, for use in the ceramist industry and in small urban industries, and in increasing use of previously agricultural land for livestock production, are forging a picture of environmental degradation, requiring, according to their natural characteristics, a model of economic use appropriate to semi-arid conditions.
