RESUMOA preocupação das empresas com o meio ambiente e com o futuro das novas gerações impulsiona ações voltadas para o gerenciamento dos recursos e incentiva a busca por ações preventivas em relação aos aspectos ambientais (por meio da minimização de impactos associados à redução de custo e da otimização de processos). Existe uma tendência no mercado mundial para a obtenção de produtos sustentáveis, oriundos de processos produtivos voltados para a redução de desperdícios e a não geração de resíduos poluentes. Dentro desse contexto, a produção mais limpa (P+L) surge como uma ferramenta completa em que simples ajustes no modo de gerir as empresas permitem a redução da emissão/geração de resíduos. A business concern with the environment and the future of the new generations drives actions for the management of resources and the search for preventive measures in relation to environmental aspects (by minimizing impacts associated cost reduction and process optimization). There is a trend in the world market to achieve sustainable, derived products production processes aimed at reducing waste and non-waste generation pollutants. Within this context, the cleaner production (CP) comes as a complete tool where simple adjustments in the way we manage the business allows the reduction of emission/waste generation. Based on this principle, we analyzed the environmental impact of the production of a manufacturer of sets of rain located in Rio Grande do Sul through a Leopold Matrix adapted process. As a result, we prepared a proposal for cleaner production practices geared ecodesign and reverse logistics. Through four stages, the proposed program CP reached its goals of agile, less bureaucratic and with low costs.Keywords: Matrix Leopold; cleaner production; ecodesign; reverse logistics. INTRODUÇÃOA preocupação com o impacto ambiental despontou nas últimas déca-das, sendo alvo de alertas cada vez mais contundentes da comunidade científica internacional, especialmente quando se considera o uso indevido de recursos naturais (NETO et al., 2010;SANTOS & CABRAL, 2013). Além do aumento econômico, deve existir uma preocupação com a proteção dos ecossistemas da Terra contra as ameaças decorrentes de nossas atividades (WU et al., 2013). As legislações que abordam as responsabilidades sobre resíduos gerados são catalisadores fundamentais para que haja maior engajamento e mudança nas empresas e nas atitudes, valores, paradigmas e práticas da sociedade (BONILLA et al., 2010).As estratégias empresariais, que até então se resumiam à questão econômica, como competitividade, eficiência, lucratividade, etc., passam a introduzir em suas preocupações a variável ambiental, tornando-se, então, vital incorporá-la aos processos produtivos. Isso levou à necessidade de modificações no âmbito da gestão e da estrutura organizacional, reorientando objetivos e metas, visando a internalização das questões ambientais nos modelos gerenciais (

“…They correspond to the constant and varying coefficient matrix methodologies respectively. The maps depict the vulnerability zones numbered in ascending order (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) from the lowest to highest air pollutant concentrations. They are based on a "worst-case scenario", which corresponds to the maximum possible CO ground level concentrations for ranges of values of each variable representative of those encountered in the study area.…”

The paper describes the development of a fast and easy-to-use qualitative tool for preliminary assessments of urban air quality related to road traffic. The tool is particularly aimed at the ability and budget of local government. It uses a novel interaction matrix-type methodology combined with mapping overlay, performed via a GIS. More specifically, the interaction matrix provides the weighting factors, which show the impact of each variable involved in a system on the target variable, air quality, as well as on the system as a whole. These weighting factors are used in the GIS to produce vulnerability maps. The maps visualise vulnerability to air pollution due to the combined effect of a number of interacting factors, and thus indicate areas susceptible to poor air quality. This results in a considerable reduction in computing time and complexity compared to the use of a sophisticated numerical model, as the user of the GIS tool only needs to perform mapping overlays in the GIS (using the previously derived weighting factors).The particular aim of this study was to compare two different methods for quantifying the interactions between variables in the matrix. The first method used constant coefficients, whose values are based on parametric studies performed using an advanced dispersion model or on good engineering judgement. The second method used a more sophisticated and versatile quantification of the interactions between variables, via analytical or semi-empirical relationships. In the latter method, the matrix was formulated computationally, so that the interaction weightings for different conditions can be obtained automatically.The technique was applied to the case study of an urban area with a high traffic throughput, in the UK. Two different interaction matrices were constructed for urban air quality linked to road traffic, based on the above methods. The GIS results based on both matrix methodologies were compared to the results of a more intensive dispersion numerical model in terms of pollutant dispersion patterns and hot spots. Both sets of results were shown to compare favourably with those of the numerical model. The results based on the more sophisticated matrix coding were found to be in closer agreement with those of the numerical model.

An improvement for rock engineering system (RES) coding method is done in this paper by using fuzzy systems. A fuzzy expert semi-quantitative coding methodology is designed to assess the cavability of rock mass within the RES framework. The proposed fuzzy method has the advantage of allowing consideration of uncertainties in the RES analysis by using membership functions in comparison with classic expert semi-quantitative coding method that only unique codes are used to quantify the interaction matrix. Since the cavability of the rock mass is one of the fundamental issues for the caving mining method, the presented improved coding method is creatively used to assess the influencing parameters on cavability of rock mass in block caving mines. Fifteen parameters are considered as the main factors modeling the cavability of the rock mass, and the interactions between these parameters are calculated by proposed fuzzy system. Finally in this paper, the parameters, which are dominant or subordinant, and also the parameters, which are interactive, are introduced. The proposed approach could be a simple but efficient tool in evaluation of the parameters affecting the cavability of rock mass in block caving mines and hence be useful in decision making under uncertainties.
