Aplicação dos conceitos de P+L e lean and green numa central dosadora de concreto

Abstract

In recent years, the generation of waste from the construction activities has grown into large proportions, and with it, the consumption of natural resources. Environmental complexity is caused by the extraction and use of these resources compromising ecosystems. The process of environmental management, applied within the construction industry, primarily aimed at reducing environmental impacts and subsequently contributes to the systematic control of the consumption of inputs and raw materials used in the production process; with possible gains in reducing negative environmental impacts and waste generation, especially with a smaller final disposal of these wastes into the environment. This study aims to develop apply the concepts of Cleaner Production and Lean and Green philosophy in a Central Concrete Dosing, with the purpose of environmentally evaluate the process of concrete production. The case study was developed based on the analysis and interpretation of environmental assessment together with a review of the documentary, photographic periodic visits and records in a Central Concrete Dosing a municipality located in the southernmost state of Rio Grande do Sul. Firstly, one environmental assessment was conducted to assess the current situation. Later qualitative and quantitative data for the preparation of environmental indicators were collected and, finally, the results gathered were analyzed. Among the results, it was found that the specific approach the concepts of Cleaner Production and Lean and Green philosophy is suitable for you can evaluate the dosing concrete plants, as well as the possibilities for the reduction of environmental impacts should be evaluated the generation of the product. There must be a good level of environmental concern ally rational use of natural resources and especially the engagement of all stakeholders, so that the company can develop a pattern of continuous improvement with a focus on sustainability. During this research it was found that if the company uses the concepts of Cleaner Production and Lean and Green philosophy as environmental assessment method in its production process is environmentally possible to manage the company, as well as reduce the impact potential impacts promoted by production concrete. It is still possible to optimize the existing process with the allowance of environmental indicators and disseminate consumer or environmental agencies improvements of the environmental aspects of its products and processes, or even environmental qualities compare with other competitors. Thus, from these concepts is possible to promote a method of environmental assessment of all emissions, the flow of raw materials used, and in order to help better environmental management and reducing environmental impacts in Concrete Batching Plants.
