In 2005, the Recycling Council of Ontario published a report that identified the construction industry as one sector that did not manage its waste in an environmentally appropriate manner. In this report, Let’s Climb Another Molehill, 15 case studies were executed to understand why this industry was neither handling nor disposing its waste properly in Southern Ontario. A set of generic recommendations was generated to help improve the management of this industry’s waste. Unfortunately the scope of the report was too broad to support conclusions about the management of specific types of problematic construction waste. The aim of this thesis is to narrow what was done in Let’s Climb Another Molehill to focus only on gypsum wallboard. The purpose of this research is to determine what options are the most desirable and feasible to deal sustainably with gypsum wallboard waste in Southern Ontario, both now and in the future. All recommendations offered are case specific. A number of methods have been utilized to obtain the information needed to formulate appropriate recommendations to deal with wallboard. Information learned through the literature, witnessed through the observation sessions, and acquired through the interviews led to two unique option categories: 1) alternative materials and 2) change in practices. To evaluate these options, a set of criteria was created based on the concepts of sustainability and integrated waste management (IWM). This sustainable IWM criteria set allowed for consistent evaluation of the options. To improve the recommendations, the sustainable IWM criteria were refined to better deal with each of the two categories of options. When the sustainable IWM criteria for evaluating alternative materials were applied, gypsum wallboard was found still to be the best interior wall material to use today. However, applying the sustainable IWM criteria for evaluating change in practices showed that the problem with using this product lies with its management and, therefore, the remaining recommendations focus on improving the creation, use and disposal of wallboard. Many of these recommendations can easily be adopted to help eliminate inappropriate wallboard management practices. This research was able to identify areas where problems arose and to offer feasible options to improve environmentally inappropriate behaviors associated with wallboard management. Although numerous recommendations are offered, the three fundamental recommendations that will lead to the biggest change include: 1) greater number of educational programs devoted to the construction industry; 2) stricter regulations and better enforcement; and 3) a dramatic increase in landfill tipping fees. If these three recommendations were implemented, it is believed that they will play a positive role in managing gypsum wallboard waste in a more sustainable manner.

O crescimento da economia brasileira proporcionou uma intensificação na quantidade de obras de infraestrutura iniciadas no país nos últimos anos. A adoção e ampliação de estratégias utilizadas pelo governo para combater os efeitos da crise internacional sobre a economia e as obras necessárias ao país, em razão de eventos internacionais que acontecerão, como a Copa do Mundo de Futebol em 2014, e de programas como o Programa de Aceleração do Crescimento (PAC), foram uma resposta às atuais necessidades do Brasil. Com essas inúmeras obras, houve um crescimento na geração dos resíduos da construção civil (RCC), o que fez com que autoridades, pesquisadores e a sociedade voltassem seus esforços para enfrentar as dificuldades de manejo e disposição final adequada desses resíduos. A ausência de políticas públicas que promovessem a fiscalização do gerenciamento desses resíduos, em relação aos geradores, provocava diversos impactos como, por exemplo, o surgimento de vários depósitos clandestinos nas áreas mais afastadas do perímetro urbano e gastos por parte da administração pública com modelos de gestão corretiva. Contudo, com a elaboração da Resolução CONAMA nº 307/2002 e da Política Nacional de Resíduos Sólidos, Decreto nº 7.404/2010 que regulamenta a Lei nº 12.305, ficou instituído que os geradores devem ser responsáveis pelos resíduos das atividades voltadas à construção civil, contemplando, assim, a minimização dos impactos causados ao meio ambiente e à saúde humana. Dessa forma, esse quadro de descaso com a situação dos resíduos começou a mudar. Com a intenção de contribuir com essa área de conhecimento, esta pesquisa teve como finalidade estudar a situação do sistema de gerenciamento de RCC de obras de grande porte, após a regulamentação da Resolução CONAMA nº 307/2002 e do Decreto nº 7.404/2010, que regulamenta a Lei nº 12.305, referente à Política Nacional de Resíduos Sólidos. Para tanto, foi realizado um estudo da situação da gestão e do gerenciamento dos RCC na demolição e construção da Arena Fonte Nova, em Salvador - BA, e na construção da Arena Pernambuco, em São Lourenço da Mata - PE, realizadas para a Copa do Mundo de Futebol de 2014, por meio de três etapas de estudo: análise das variáveis e indicadores locais; caracterização qualitativa dos resíduos; e, por fim, comparação do gerenciamento da obra com o preconizado em ambas as leis. Esta pesquisa utilizou metodologia de classificação qualitativa do RCC, por meio de observações e entrevistas de campo, com o objetivo de identificar e analisar sua gestão e seu gerenciamento nessas obras, e teve como principal importância ajudar as empresas construtoras de obras de grande porte a fazerem uma autoavaliação de sua gestão e gerenciamento dos resíduos sólidos. Portanto, concluiu-se que as obras pesquisadas atendem às exigências das leis e que, para que haja um efetivo sistema de gestão e gerenciamento dos resíduos da construção civil, deve-se influenciar a mudança cultural das pessoas, visando a efetiva compreensão e concordância das necessidades ambientais. / The Brazilian economy has provided an enhancement in the amount of infrastructure works initiated in the country in recent years. The adoption and expansion of strategies used by the government to combat the effects of global crisis on the economy and the works necessary for the country due to international events that will happen as the FIFA World Cup in 2014 and programs such as PAC (Program Growth Acceleration), were a response to the current needs of Brazil. With these numerous works, there was an increase in the generation of civil construction waste (CCW), which meant that the authorities, researchers and society return their efforts to face the difficulties of handling and final disposal of such waste. The absence of public policies that promote the monitoring of waste management in relation to generators, caused many impacts, for example, the emergence of several underground deposits in the areas furthest from the urban perimeter and spending by the public administration models corrective management. However, the drafting of the CONAMA Resolution 307/2002 and the National Policy on Solid Waste Decree 7.404/2010 which regulates Law 12,305, it was established that the generators should be responsible for waste from activities related to construction, encompassing thus minimizing the impacts to the environment and human health. Thus, this picture of neglect with the waste situation began to change. Intending to contribute to this area of knowledge, the present study was aimed to study the situation of the CCW management system for large works, after the implementation of Resolution CONAMA 307/2002 and Decree regulating 7.404/2010 Law 12,305, on the National Policy on Solid Waste. To that end, a study of the CCW management situation was conducted in the demolition and construction of the Arena Fonte Nova in Salvador - Bahia, and in the construction of the Arena Pernambuco in São Lourenço da Mata - PE, performed for the FIFA World Cup 2014, through three stages of study: analysis of variables and local indicators, qualitative characterization of the waste and, finally, comparing the CCW management as recommended in both laws. This research used the qualitative methodology of the CCW, through field observations and interviews, in order to identify and analyze the management of these same works and its main importance to help manufacturers of major works to make a self- evaluation of its management and solid waste management. Therefore,it was concluded that the works researched met the requirements of laws and that to have an effective management system of civil construction waste, must influence cultural change in the people, in order to enhance comprehension and compliance of environmental needs.

In this sense, it is important to know the local, regional and national reality, for analysis of the management of the Waste of Civil Construction (RCC), checking the positive and negative aspects, allowing to contribute to the formulation of public policies, which to assess these aspects. In this sense, this research is justified, which has as central objectives, to analyze the state of the art of the management of the waste of civil construction in the state of Paraná and in the municipality of Cascavel-PR, in order to contribute with the scientific community to knowledge of the current reality, in addition to identifying the relevant legislation and the management processes, with the future aim of subsidizing actions and strategic planning, which aims at the sustainability of the civil construction sector, with regard to the aspects social, environmental and economic. For the scope of the proposed objectives, descriptive methodology was used, through bibliographical research and data collection, in addition to the mixed method, which consists in the collection and analysis of qualitative and quantitative data, the results evaluated in a way Integrated. The results showed that within the state of Paraná, 60% of municipalities present specific legislation for the implementation of the Waste Management Plans of Civil Construction (PGRCC), and that 92.6% of the localities still earmarked the RCC to landfills With the rest of the municipal waste, or disposal in improper locations. In the municipality of Cascavel-PR, the surveys in the construction sites pointed out some negative aspects in the management of the RCC, such as the lack of training of the employees responsible for the works, irregular disposal of the RCC, as well as absence of supervision of the competent bodies for further final approval of the PGRCC. The analysis of the results obtained made it possible to conclude the difficulty of obtaining precise data and that in this sense new studies and diagnostics are fundamental to the knowledge of the reality in its entirety, moreover, in the municipality of Cascavel-PR, it is made the improvement of the management tools of the existing RCD. / O setor da construção civil gera um volume expressivo de resíduos sólidos, de modo geral, tais resíduos nem sempre possuem uma gestão adequada, sendo depositados em locais indevidos, e consequentemente comprometendo a qualidade do ambiente. Nesse sentido, é importante o conhecimento da realidade local, regional e nacional, para análise da gestão dos Resíduos da Construção Civil (RCC), verificando os aspectos positivos e negativos, permitindo contribuir para a formulação de políticas públicas, que visem avaliar tais aspectos. Nesse sentido, justifica-se a presente pesquisa, que tem como objetivos centrais, analisar o estado da arte da Gestão dos Resíduos da Construção Civil no Estado do Paraná e no município de Cascavel-PR, a fim de contribuir com a comunidade científica para conhecimento da realidade atual, além de identificar a legislação pertinente e os processos de gestão, com o intuito futuro de subsidiar ações e um planejamento estratégico, que vise à sustentabilidade do setor da construção civil, no que se refere aos aspectos sociais, ambientais e econômicos. Para o alcance dos objetivos propostos utilizou-se a metodologia descritiva, por meio de pesquisa bibliográfica e coleta de dados, além do método misto, que consiste na coleta e análise de dados qualitativos e quantitativos, sendo os resultados avaliados de forma integrada. Os resultados mostraram que no âmbito do Estado do Paraná, 60% dos municípios apresentam legislação específica à implantação dos Planos de Gerenciamento dos Resíduos da Construção Civil (PGRCC), e que 92,6% das localidades ainda destinam os RCC aos aterros sanitários, juntamente com os demais resíduos urbanos, ou realizam o descarte em locais impróprios. No município de Cascavel-PR, as vistorias nos canteiros de obras apontaram alguns aspectos negativos na gestão dos RCC, como por exemplo, falta de treinamento dos funcionários responsáveis pelas obras, descarte irregular dos RCC, bem como ausência de fiscalização dos órgãos competentes para posterior aprovação final do PGRCC. A análise dos resultados obtidos permitiu concluir a dificuldade de obtenção de dados precisos e que nesse sentido novos estudos e diagnósticos são fundamentais para conhecimento da realidade em sua totalidade, além disso, no município de Cascavel-PR, faz-se necessário o aperfeiçoamento dos instrumentos de gestão dos RCD vigentes.

Global use of natural resources has accelerated during the past decade and emissions and waste have increased as a consequence. The construction sector is a major contributor to global carbon emissions and is responsible for as much as one-third of global greenhouse gas emissions. The negative impact that industries across the world are having on the environment is getting recognized as a serious problem and the environmental awareness is growing. A significant amount of this impact could be reduced with increased resource efficiency. Our economic system needs to undergo an unprecedented transformation, to stop environmental degradation but also to assure sustainable access to natural resources in the future. To tackle this issue, institutions are pressuring to move away from our current linear economy with its “take-make-dispose” characteristics and move towards a circular economy that is waste-free by design. The concept of Industrial Symbiosis is seen as a means to do that. In these industrial networks that resemble biological symbioses, waste or by-products of one company become a resource for another. By engaging traditionally separate industries in a collective approach involving physical exchange of materials, energy and by-products, it is possible to divert waste from landfill and reduce the negative impact on the environment. From a company perspective, Industrial Symbiosis can reduce the need for raw materials as well as waste disposal costs while allowing companies to create new revenue from residue and by products. The aim of this report was to investigate the perspectives that stakeholders have on a potential participation in an Industrial Symbiosis network and the complex interplay of drivers, facilitators and barriers to the implementation, as well as how the responsibilities among the stakeholders could be divided in order to implement this concept in the most effective way. This was done by interviewing key stakeholders within the construction industry to get an overall perspective on their views. The results indicated a generally positive outlook on the concept of Industrial Symbiosis among the stakeholders. Key drivers and barriers were identified as economic – companies are only willing to invest if it is profitable, regulatory – regulations are an important enabling factor as they create the right incentives for companies to participate, organizational – A transformation of the business model is necessary in order to implement circular economy and technological – Technological developments and innovations will aid the implementation as it can increase efficiency and transparency among the network participants. A tentative model has been generated where the responsibility distribution among the stakeholders have been mapped in order to give a greater understanding of the dynamics of a potential network. / Den globala användningen av naturresurser har ökat under det senaste decenniet och utsläpp och avfall har vuxit som en följd. Byggsektorn är en stor bidragande faktor till globala koldioxidutsläpp och ansvarar för så mycket som en tredjedel av de globala utsläppen av växthusgaser. Den negativa påverkan som industrier över hela världen har på miljön erkänns som ett allvarligt problem samtidigt som miljömedvetenheten växer. En betydande mängd av denna påverkan kan minskas med ökad resurseffektivitet. Vårt ekonomiska system måste genomgå en enastående omvandling, för att stoppa miljöförstöring men också för att säkerställa hållbar tillgång till naturresurser i framtiden. För att ta itu med denna fråga pressar institutionerna att flytta sig bort från vår nuvarande linjära ekonomi och gå mot en cirkulär ekonomi som är avfallsfri genom design. Begreppet Industriell Symbios ses som ett sätt att göra det. I dessa industriella nätverk som liknar biologiska symboler blir avfall eller biprodukter från ett företag en resurs för ett annat. Genom att engagera traditionellt separata industrier i en kollektiv strategi som involverar fysiskt utbyte av material, energi och biprodukter, är det möjligt att avleda avfall från deponering och minska den negativa miljöpåverkan. Ur ett företagsperspektiv kan Industriell Symbios minska behovet av råmaterial samt avfallskostnader samtidigt som företag kan skapa nya intäkter från rester och av produkter. Syftet var att undersöka de synpunkter som intressenter har på ett potentiellt deltagande i ett Industriellt Symbios-nätverk och det komplexa samspelet mellan aktörer för genomförandet, samt hur ansvaret mellan aktörerna ska delas upp för att implementera detta koncept på det mest effektiva sättet. Detta gjordes genom att intervjua viktiga aktörer inom byggbranschen för att få ett övergripande perspektiv på deras åsikter. Resultaten indikerade en generellt positiv syn på konceptet industriell symbios bland intressenterna. Viktiga drivkrafter och hinder identifierades som ekonomiska - företag är bara villiga att investera om det är lönsamt, regelverk - förordningar är en viktig möjliggörande faktor eftersom de skapar rätt incitament för företag att delta, organisatoriska - En omvandling av affärsmodellen är nödvändig i för att genomföra cirkulär ekonomi och teknik - Teknologisk utveckling och innovationer hjälper implementeringen eftersom det kan öka effektiviteten och öppenheten bland nätverksdeltagarna. En modell har genererats där ansvarsfördelningen bland intressenterna har kartlagts för att ge en större förståelse för dynamiken i ett potentiellt nätverk.

[pt] Existem milhares de técnicas e metodologias construtivas sustentáveis, e para o tratamento e reaproveitamento do resíduo da construção civil nos centros urbanos. Esse trabalho procura ordenar, de forma sintetizada, esses procedimentos para redução da geração e reaproveitamento do resíduo da construção civil no Rio de Janeiro, apresentando sugestões para as fases de idealização, projeto e execução do empreendimento e uma logística reversa para a reinserção do resíduo à cadeia produtiva. A pesquisa sugere no capitulo dois a utilização da ferramenta de Avaliação do Ciclo de Vida (ACV) na fase de idealização dos empreendimentos para uma visão ampla do impacto ambiental durante a execução da obra e na utilização do empreendimento até o descarte final, mostrando que a manutenção na fase de utilização representa mais de oitenta por cento do custo de toda a sua vida útil. O capitulo três apresenta uma analise do resíduo, sua composição, as classificações de acordo com o CONAMA e NBR 10.004, e seu potencial de impacto nas regiões urbanas, as principais fontes geradoras, um resumo das principais leis e resoluções brasileiras que regulamenta a sua gestão. Trás ainda uma comparação entre tipos de desconstruções com apresentação de um exemplo de uma demolição certificada no centro do Rio de Janeiro. O capitulo quatro apresenta um panorama geral da gestão dos resíduos da construção civil nas grandes cidades, evidenciando no Rio de Janeiro a existência de dois tipos distintos de geradores de resíduos na construção civil, o gerador das obras com canteiros instalados, licenciados, que segue as normas e exigências técnicas para seletividade do resíduo e os geradores das pequenas obras e reformas, responsável pela contribuição acima de 50 porcento do total de resíduo gerado e pela quase totalidade da poluição. O capitulo cinco trabalha sobre a formula: (Sustentabilidade = Projetos eficientes + Reaproveitamento dos detritos). Projetos eficientes, obras com baixa geração de resíduos e erradicação dos desperdícios é o caminho para a sustentabilidade no setor. Apresenta métodos construtivos para esse objetivo e sustenta que a segregação do resíduo na fonte é pré condição para um processo eficiente de reciclagem. Apresenta o Social como o principal legado da logística para reciclagem dos resíduos nas grandes cidades nos países em desenvolvimento. O capitulo seis propõe um caminho para a logística de reciclagem do resíduo da construção civil no Rio de Janeiro, transformando o processo linear em um processo circular para a indústria da construção civil. O fim do despejo de resíduo da construção civil in natura é uma meta a ser continuamente perseguida por toda a sociedade no compromisso com as gerações futuras. Esse trabalha apresenta sugestões para esse fim. / [en] The historical importance of the construction industry in the constant improvement of society s quality of life is undeniable. A major source of employment, it accounts for twenty percent of all U.S. economic activity, and in Brazil, in 2008, it represented 8.9 percent of the GDP; in 2000 it consumed 210 million tons of natural aggregates. These figures express the sector s strategic need justifying investments in research for its sustainability, which is currently less than 1 percent from the U.S. government and 6 percent in Europe. There are thousands of sustainable building techniques and methodologies, as well as those for the treatment and reuse of construction waste in urban centers. This article aims to organize, in a summarized way, these procedures to reduce generation and treat construction waste in Rio de Janeiro, making suggestions for sustainable processes in the idealization, design and implementation phases of a new development and the reverse logistics for treating waste and reintegrating it into the production chain. In chapter two the study suggests the use of the Life Cycle Assessment (ACV) tool during new developments idealization phases for a broad overview of the environmental impact of their execution, during the use of the developments until their final disposal. Research shows that maintenance costs in a development s utilization phase represent more than eighty percent of its entire life span. The ACV study qualifies knowledge of sizing, materials specifications and construction techniques, as well as routines for use of developments. It adjusts its viability guiding developments toward sustainable principles, for example, low power consumption settings, minimizing the use of natural resources, parameters for diversity of materials being used, the impact of the use of assembly and/or mounting adhesives that hinder selective disassembly for reuse, and the importance of planning deconstruction ahead of time in order to reuse materials; these factors are crucial in the quest for sustainability in the sector. Chapter three brings an analysis of this waste, its impact potential in urban areas, major generating sources, and a summary of the main Brazilian laws and resolutions regulating its management. By listing the main sources generating waste and scrap in construction, attention is drawn to the selective deconstructions of yesteryear that reused materials. Made viable by the construction techniques used at that time in these buildings that allowed the selective removal of material. Also in chapter three, an example of a current certified demolition in downtown Rio de Janeiro is presented. Finally, it shows the general composition of waste and its classifications according to CONAMA (the National Environment Council) and NBR (Brazilian Technical Standards Association) 10,004. Chapter four provides an overview of construction waste management in large cities, in Rio de Janeiro it is evident that two distinct types of waste generators exist in constructions: the first is the generator in construction works with installed and licensed construction sites, which follow the standards and technical requirements for waste selection from generation to transportation under joint liability during the whole process until the final destination, in accordance with CONAMA s resolutions; these generators are monitored throughout the process. Yet the second, the generator in small construction works and renovation without installed construction sites, they do not comply with waste management standards and requirements, they use the same bucket to carry all classes of mixed waste, with no responsibility for the segregation and final disposal. Most often these wastes are dumped in illegal transshipment areas, mostly in protected areas. This widespread practice under the pretext of lack of segregation space in the civil work is endorsed by the lack of an urban policy to empower and require waste segregation at source and its reprocessing. The segment of small generators is responsible for contributing over 50 percent of waste generated in the city, and for almost all of the total pollution generated by construction waste, due to their crude mixtures that cannot be recycled and untreated transshipments into nature. Thus this study focuses on studying a suggestion for waste segregation logistics and recycling for this second group of generators. Chapter five dissects the formula: (Sustainability = Effective projects + Waste reutilization). Efficient projects, civil works with low waste generation and waste elimination is the way toward sustainability in the sector. In some regions of Brazil, the loss reaches 33 percent as opposed to the world average of 10 percent. Several factors rooted in the country s culture of raw material abundance are mentioned. There is still a lack of sustainable efficiency concern in national projects, of doing more using fewer natural resources, using construction methods to lower the impact on the use and disposal of materials in the process.
