Surveys carried out in many Brazilian cities have shown that the CDW Construction and Demolition Waste, in some cases, represent more than 50% of the mass of urban solid residue. Municipalities have struggled to manage in an effective way huge quantities of CDW generated every day and solve the problem of the illegal dumping in an inadequate area, which compromise the quality of life of the population as a whole, thus causing serious problems concerning social-environmental and sanitary. This paperwork was meant it carry out environmental diagnosis of the management and the final destination of the CDW in the city of Parnamirim/RN. The methodology used in this work constituted in the bibliographical research, conducted to give support and fundaments to the subject in question, identification of the main places of legal and illegal dumping, identification of the environmental impacts caused by the irregular deposition of the CDW, valuation of quantity and quality of the CDW and perception according to the Environmental Legislation. The necessary data for the elaboration of this study were carried out through the appliance of questionnaires with open and closed questions, applied to 14 (fourteen) Real Estate developer companies associated with SINDUSCON/RN and 05 companies that deal with the transportation and collection of CDW, formal and informal interviews, exploitational visits and photographical records. The collected data went through a statistic treatment being organized into tables and graphs. The main results obtained from this research show that the interviewees hold a medium knowledge of the specific Environmental Legislation; do not have an effective model of environmental management, resorting to only reusing CDW; that the reusing of CDW is not substantial, as much as the possibility of recycling has a minimal consideration. It was also verified that a considerable percentage of interviewees affirmed to send CDW to illegal and inadequate locations. It is expected that such study can be used as an important tool to subsidize the public administration in the pursuit of solutions which could bring benefits to society and the environment

The problem of solid waste has caused discussions about the huge amount that is generated in Brazilian cities, in particular the waste from construction and demolition (CDW), called spoil. In many cases these wastes are disposed of improperly and even criminally in urban areas, causing serious economic, social and environmental problems. Due to the lack of public policies and appropriate management of such waste came up with the CONAMA, in its resolution nº 307 of 2002, the obligation of municipalities in deploy the integrated management of construction and demolition wastes for the resolution of problems caused by inadequate management and disposal of such waste. By following a methodology suggested by Pinto & González (2005), with adaptations of other authors, it is proposed in this work the lifting of a diagnosis of the CDW in the municipality of Guaratinguetá-SP, through theoretical analysis and field research, with purpose to guide the public servants in the elaboration and implementation of integrated management. The results must contain information necessary for that end, such as the knowledge of generators, agents, collectors and transporters, disposition areas and the disposal of waste

Taking as starting the environmental, social and economic impact of construction and demolition waste in Brazilian cities were created legal mechanisms for management and administration, seeking to minimize the impacts to the maximum, since the irregular deposition can be characterized as environmental crime. CONAMA Resolution No. 307 of 2002 establishing the mandatory implementation of an Integrated Management System Construction Waste and Demolition, guiding the classification and designation of the waste generating agents, collection agents and transporters, and the areas of culling and disposal of waste. The technical partnership between the Ministry of Cities, the Environment Ministry and the Caixa Econômica Federal, coordinated by Pinto & Gonzales (2005) Management in the work and management of construction waste, proposed a guidance manual to guide the implementation of a System Integrated Management of Construction Waste in Municipalities. The municipality of Guanambi in the state of Bahia, in full economic rise, lacks a waste management of construction and demolition, since there has areas for the disposal of waste being proposed in this paper the diagnosis of waste generation in the municipality as part of the methodology proposed by the work of Pinto & Gonzales (2005).

Nas últimas décadas temos assistido a um crescimento da produção de resíduos de construção e demolição. Surge então a necessidade de fazer uma gestão consciente destes resíduos reintroduzindo-os quando possível, no ciclo de vida de novas construções, provocando uma redução quer das zonas de aterro quer da abertura de novas zonas de extração de inertes as quais, provocam um elevado impacto ambiental afetando a biodiversidade existente nessas zonas. Com esta intenção, o presente trabalho centra-se na temática do betão com agregados reciclados e pretende contribuir para o seu conhecimento, analisando as características quer dos agregados reciclados quer do betão com eles confecionado, seguindo normas e diretrizes recomendadas por diferentes especificações um pouco por todo o mundo. Ainda no mesmo contexto o estudo pretende conhecer o destino (eliminação, aterro, valorização, etc.) dado aos RCD procedentes de betão na Região Autónoma da Madeira. A análise da bibliografia existente demonstra perdas nas características destes betões reciclados quando comparados com betões convencionais, isto sem dúvida devido principalmente à quantidade de pasta de cimento aderido presente na composição do agregado reciclado, a qual afeta direta e indiretamente a maioria das propriedades quer do agregado reciclado quer do betão com eles confecionado. Foi recolhida informação que permite caracterizar o sector da construção civil, fazendo o diagnóstico do estado atual da gestão dos resíduos de construção e demolição que é feita pelas empresas de construção sediadas na RAM, mais concretamente a gestão dos resíduos de betão e a reutilização e reciclagem dos mesmos.

The present work has the objective of presenting an investigation about the quantification, classification and destination of the waste of construction and demolition (RCD) in the city of Natal - RN, focusing the aspects of the environmental impacts and the strategic importance of the environmental administration in the earnings of productivity of the companies. Of the environmental point of view the research intends to identify and to quantify the monthly and annual production of RCD in the city, as well as to know the places of deposition of those residues. To reach the objectives of the study, an exploratory and descriptive research was accomplished, using a questionnaire with closed subjects and an open one, applied in 25 entrepreneurs of the branch of the building site, being 21 builders and 4 entrepreneurs of collection companies and removal dumps. As form of analysis of the data, the descriptive analysis was used and of crossing. The production engineering considers important the insert of best production practices and administration of the product in the companies, with views to the increase of your competitiveness, productivity earnings and improvement of the environmental aspects with views to the consumer's satisfaction, in that case the buyer of immobile. The principal results of the investigation demonstrate that there was not great variability of answers with relationship to the interviewees opinion in what he refers to the environmental practices. In your majority the building site interviewees entrepreneurs evidenced the absence of the public power, particularly the city hall of Natal, in the control, fiscalization and creation of mechanisms for a correct destination of RCD, as well as for your reuse and recycle. On the other hand also it was evident that the recycle or the reuse of RCD on the part of the companies is a rare practice and a lot of times inexistent, although the entrepreneurs' of the building site section great majority recognizes that would have won of productivity with the correct and intensive use of such measures
