A indústria calçadista faz intenso uso de recursos naturais e gera grande volume e diversidade de resíduos ao longo da produção; muitos deles são perigosos, oferecendo riscos ao ambiente e à saúde humana. Nos produtos, é utilizada ampla variedade de materiais, o que dificulta o seu tratamento ao fim da vida útil, tornando o resíduos pós-consumo um agravante para a questão dos resíduos nessa indústria. A abordagem da prevenção de resíduos busca, de maneira proativa, diminuir ou evitar o ingresso de materiais ou substâncias no fluxo dos resíduos, prevenindo assim os impactos causados por eles no ambiente. A adoção de práticas preventivas na indústria de calçados pode contribuir para mitigar impactos oriundos de todo o ciclo de vida desse produto. Assim, esta pesquisa teve o objetivo de estudar o fenômeno da prevenção de resíduos na indústria calçadista brasileira, buscando sistematizar iniciativas e práticas já existentes e discuti-las à luz da literatura, de modo a encontrar desafios e oportunidades para expansão dessas atividades. Para a análise dos achados, adotou-se o viés conceitual da Ecologia Industrial. Foi realizado um estudo de caso descritivo-exploratório de caso único a indústria calçadista brasileira com múltiplas unidades de análise, buscando responder às seguintes perguntas: i) Como vem ocorrendo a prevenção de resíduos na produção de calçados?; ii) Quais são os desafios e oportunidades para avanços da prevenção nesse setor? A pesquisa revelou que a adoção de atividades de prevenção na indústria calçadista ainda ocorre de maneira tímida, e foca principalmente a escolha por materiais com menor toxicidade ou reciclados, e a eficiência no uso de matérias-primas. Esta última está muito ligada à redução de custos; no setor de componentes ocorre principalmente na indústria química, com o reaproveitamento interno dos subprodutos, e na manufatura, ocorre na otimização do corte das partes do calçado. De modo geral, a produção calçadista brasileira se caracteriza por intensa competitividade, com a busca por redução de custos e maximização de ganhos. Isso apresenta desafios para a implementação das atividades de prevenção de resíduos por colocar como prioridade a busca por preços baixos, geralmente obtidos pela externalização de custos socioambientais; além disso, prejudica o interesse em colaborações entre empresas. As cadeias de produção são extensas e pouco articuladas, o que dificulta a circulação de informações e materiais entre empresas. Com relação aos materiais, a pesquisa revelou possibilidades de ciclagem dentro do ambiente produtivo para diversos deles, embora não sejam colocadas em prática. O caso da indústria calçadista brasileira se apresentou como emblemático para a crise do sistema econômico nos moldes do paradigma técnico-científico, (segundo o qual o desenvolvimento significa crescimento econômico), evidenciando a necessidade de uma mudança de paradigma e uma nova racionalidade material. / The footwear industry is characterized by intense natural resources input and large and diverse waste generation, many of which are hazardous, offering risks to the environment as well as human health. A wide variety of materials are used in the products, which hampers the treatment of post-consumption waste, worsening the scenario for the issue of waste in the footwear industry. Waste prevention aims at preventing or reducing both quantitative and qualitatively the waste flows, and thus, the environmental impacts caused by them. The adoption of prevention activities in the footwear industry contributes to the mitigation of several impacts associated with this products life cycle. This research had the objective of studying waste prevention in the Brazilian footwear industry, as to unveil and systematize existing initiatives and practices, discussing them in light of the literature on the subject and identifying the challenges and opportunities for their progress. The conceptual basis of Industrial Ecology was used to analyze the findings. A descriptive-exploratory single case study with multiple analysis units was conducted aiming at answering the research questions: i) How have waste prevention activities been occurring in the footwear production?; ii) What are the challenges and opportunities for the progress of waste prevention in this area? The research found that waste prevention activities in the footwear industry are still timid, focusing mainly the selection of less toxic or recycled materials, as well as efficiency in the use of raw materials. The last is connected to cost reduction, taking place in the component sector mainly in the chemical industry through the internal reutilization of byproducts and in the manufacture sector, through efficient cutting of the parts. In general, the Brazilian footwear production is characterized by high competitiveness, pursuing cost reduction and gain maximization. That presents challenges for the implementation of waste prevention activities for setting low prices as priority, usually obtained by the externalization of social and environmental costs. It also harms the interest in collaboration between organizations. The supply chains are wide and lack articulation, which hinders information and materials circulation between organizations. Regarding the materials, the research found cycling possibilities within the productive environment for several of them, although these are not put into practice. The case of the Brazilian footwear industry is emblematic for the crisis in the economic system based in the technical-scientific paradigm (according to which, development is equal to economic growth). It underlines the need for a paradigm shift, as well as a new material rationality.

L’écologie industrielle a pour objectif de résoudre les questions liées à l'utilisation des ressources technologiques dans les sociétés, dans le but d'ajouter à la partie des connaissances nécessaires pour commencer à évaluer les problèmes de qualité liés à l'environnement et les questions de disponibilité des ressources. Le concept d’écologie industrielle peut être réalisé et pratiqué à travers d’établissement des parcs éco-industriels. Un parc éco-industriel est une communauté de fabrication et de service des entreprises situées ensemble sur une propriété commune. Les membres cherchent la performance environnementale, économique et sociale accrue grâce à la collaboration dans la gestion des questions environnementales et de ressource. L’objectif principal de la thèse est de créer des modèles mathématiques d’optimisation pour maximiser des flux des échanges dans un parc éco-industriel et pour réduire les impacts négatifs des industries sur l’environnement. Les sept parcs éco-industriels symboliques et emblématiques dans le monde ont été étudiés durant la thèse pour obtenir une vision pratique de la problématique et pour acquérir les informations du développement des éco-parcs de la réalité. Les dix outils informatiques et les modèles d’optimisation pour les parcs éco-industriels ont été étudiés. Trois modélisations d’optimisation sont proposées avec les simulations numériques effectuées. / Industrial ecology aims to resolve issues related to the use of technological resources in societies in order to add to the party the knowledge to begin to assess quality issues related to the environment and resource availability issues. The concept of industrial ecology can be realized and practiced through the establishment of eco-industrial parks. An eco-industrial park is a manufacturing community and service businesses located together on a common property. Members seek environmental performance, increased economic and social through collaboration in managing environmental and resource. The main aim of this thesis is to create mathematical optimization models to maximize trade flows in an eco-industrial park and to reduce the negative impacts of industry on the environment. The seven symbolic eco-industrial parks have been studied in this thesis in order to get a practical view of the issues and to acquire information from the development of eco-parks in reality. The numerical tools and optimization models for eco-industrial parks were studied. Three optimization models have been proposed with numerical simulations in this thesis.

This report focuses on governance mechanisms for industrial symbiosis (IS). The study takes an organizational approach on material and energy exchanges between different organizations (or different parts in the same organization) leading to increased regional resource efficiency. This project explores different strategies for governance mechanisms and analyzes how these affect trust. Significant factors for initiating and keeping a collaboration successful are also analyzed. Representatives from 24 Swedish cases of symbiotic arrangements are interviewed and ten themes affecting IS collaborations are identified. The themes are governance structure, shared vision, previous collaboration, local conditions, initiating a collaboration, activities to build trust, conflicts, transaction-based or goal-oriented approach, indicators and distribution of costs and benefits. Among the governance structures used are hierarchy (collaboration between different parts of the same organization), joint venture, strategic alliance and different types of agreements. Common is a 10-15 years agreement, sometimes combined with a strategic discussion about the development of the collaboration. Three factors particularly affecting collaborations are identified: strategic meetings, indicators related to the collaboration and fair profit distribution. The factor strategic meetings is about combining long term agreements with innovation. Long term agreements might be necessary when a project requires investments. Meanwhile, this can suppress innovation by supporting outdated solutions. The paradox of needing both long term agreements and continued innovation may be solved by the practice of having strategic meetings and contract surveillance. Another significant factor for successful collaborations is the use of jointly evaluated indicators. To jointly evaluate a project according to predetermined indicators gives all parties the opportunity to know when a collaboration is successful. The third significant factor is fair profit distribution. Unfair profit distribution may delay or stop a project. It may also decrease trust in an ongoing project. A fair profit distribution is a key factor for enabling long term relationships. / Den här rapporten studerar samarbetsformer för industriell symbios (IS). Fokus för den här studien är material- och energiutbyten mellan organisationer eller mellan olika delar i samma organisation som leder till regional resurseffektivisering. Val och implementering av samarbetsform analyseras i relation till förtroende mellan organisationer och lyckade samarbeten. Viktiga faktorer för att lyckas starta och bibehålla ett symbiossamarbete analyseras också. Representanter från 24 svenska fall av symbiotiska samarbeten intervjuas och deras svar analyseras utifrån tio teman: samarbetsform, gemensam vision, tidigare samarbete, lokala förutsättningar, att starta ett samarbete, aktiviteter för att bygga förtroende, konflikter, transaktionsbaserat eller målinriktat förhållningssätt, indikatorer och vinstfördelning. Bland de samarbetsformer som används återfinns hierarki (samarbete mellan olika delar i samma organisation), joint venture, strategisk allians och olika typer av avtal. Vanligt är avtal på 10-15 år, ibland kombinerat med en strategisk diskussion om samarbetets utveckling. Tre faktorer identifieras som extra viktiga vid symbiotiska samarbeten: strategiska möten, indikatorer relaterade till samarbetet och rättvis vinstfördelning. Strategiska möten handlar om att kombinera långsiktiga avtal med innovation. Långsiktiga avtal behövs ofta i symbiossamarbeten för att kunna göra investeringar. Samtidigt kan detta låsa fast utdaterade lösningar och försvåra innovation och utveckling. Att ha avtalsbevakning och en strategisk diskussion kring utveckling av samarbetet har identifierats som ett sätt att lösa detta på. En annan betydande faktor för lyckade samarbeten är gemensamma indikatorer relaterade till samarbetet. Att gemensamt utvärdera samarbetet enligt uppsatta indikatorer ger alla parter möjlighet att veta när ett samarbete lyckats. Den tredje identifierade faktorn är rättvis vinstfördelning. Orättvis vinstfördelning kan stoppa eller försena ett samarbete. Det kan också urholka parternas förtroende till varandra. En rättvis vinstfördelning kan däremot skapa förtroende och är en nyckelfaktor till ett långsiktigt samarbete.

Separation, removal, and relocation are the initial steps in the “clean-up” of a contaminated site. While crucial to safeguarding the public health of adjacent communities and the surrounding environment, conventional remediation is subtractive from the community leaving many psychological wounds untreated. Architecture has the greatest potential to address the social concerns which contribute to the complexities of redeveloping a contaminated site. Focusing on the 52 acre former General Electric Brownfield site in Pittsfield, Massachusetts, I have explored through design alternative approaches for the redevelopment of contaminated sites. My design research focuses on the ways in which architecture can be used as a tool to desensitize the legacy of post-industrial contaminated sites within our communities and create spaces of sustainable coexistence between for our greater economic, environmental, and communal interests.

Many of the present problems that we are facing arise as unanticipated side-effects of our own actions. Moreover, the solutions implemented to solve important problems often create new problems. To avoid unintended consequences, understanding complex systems is essential in devising policy instruments and in improving environmental management. Thus, this thesis investigated systems modeling approaches to under- stand complex systems and monitor the environmental performance of management actions. The overall aim of the work was to investigate the usefulness of different systems modeling approaches in supporting environmental management. A driver- based, pressure-oriented approach was adopted to investigate systems modeling tools. Material/substance flow analysis, environmental footprinting, input-output analysis, process-based dynamic modeling, and systems dynamics modeling approaches were applied in different cases to investigate strengths and weaknesses of the tools in generating an understanding of complex systems. Three modeling and accounting approaches were also tested at different systems scales to support environmental mon- itoring. Static modeling approaches were identified as fundamental to map, account, and monitor physical resource metabolism in production and consumption systems, whereas dynamic modeling showed strengths in understanding complex systems. The results suggested that dynamic modeling approaches should be conducted on top of static analysis to understand the complexity of systems when devising and testing policy instruments. To achieve proactive monitoring, a pressure-based assessment was proposed instead of the mainstream impact/state-based approach. It was also concluded that the LCA community should shift the focus of its assessments to pressures instead of impacts. / Många nuvarande miljö- och utvecklingsproblem har uppstått som oförutsedda biverkningar av människans egna handlingar. De lösningar som prövats har i sin tur ofta skapat  nya problem. Det därför viktigt att förstå hur komplexa system fungerar och att utforma styrmedel och ledningssystem som minimerar risken för oönskade bieffekter. Den här avhandling har använt olika modelleringsmetoder för att öka förståelsen för komplexa system och bidra med kunskaper om hur miljöprestanda och förvaltningsåtgärder kan följas upp på ett mer effektivt sätt. Det övergripande syftet med arbetet var att undersöka användbarheten av olika modelleringsmetoder för att effektivisera den fysiska resurshanteringen i samhället. I arbetet har ett flödesbaserat och aktörsinriktat arbetssätt (pressure based and driver oriented approach) använts i modelleringen.  Material- och substansflödesanalys, miljöfotavtryck, input-output analys, processbaserad dynamisk modellering och systemdynamiska modelleringsmetoder studerades för att undersöka styrkor och svagheter hos de olika metoderna/verktygen.  Tre olika modellerings- och redovisningsmetoder för att stödja miljöövervakning testades också i olika systemskalor. Statiska modelleringsmetoder (räkenskaper) identifierades som grundläggande för att kartlägga, kontoföra och övervaka den fysiska resursmetabolismen i produktions- och konsumtionssystem, medan dynamisk modellering visade sin styrka i att skapa förståelse för komplexa system. Resultaten pekar på att dynamiska modelleringsmetoder bör användas som ett komplement till statiska analyser för att förstå komplexiteten i systemen när man utformar och testar styrmedel. För att uppnå proaktiv övervakning bör flödesbaserade räkenskaper utnyttjas i större utsträckning i stället för den vanliga tillstånds- och påverkansövervakningen (state/impact monitoring). En viktig slutsats är därför att LCA-samfundet bör flytta fokus i sina bedömningar från påverkan till flöden. / <p>QC 20160830</p>

This research is an attempt to create a comprehensive assessment framework for identifying and assessing potential improvement options of cement production systems. From an environmental systems analysis perspective, this study provides both an empirical account and a methodological approach for quantifying the CO2 footprint of a cement production system. An attributional Life Cycle Assessment (LCA) is performed to analyze the CO2 footprint of several products of a cement production system in Germany which consists of three dierent plants. Based on the results of the LCA study, six key performance indicators are dened as the basis for a simplied LCA model. This model is used to quantify the CO2 footprint of dierent versions of the cement production system. In order to identify potential improvement options, a framework for Multi-Criteria Assessment (MCA) is developed. The search and classication guideline of this framework is based on the concepts of Cleaner Production, Industrial Ecology, and Industrial Symbiosis. It allows systematic identication and classication of potential improvement options. In addition, it can be used for feasibility and applicability evaluation of dierent options. This MCA is applied both on a generic level, reecting the future landscape of the industry, and on a production organization level re ecting the most applicable possibilities for change. Based on this assessment a few appropriate futureoriented scenarios for the studied cement production system are constructed. The simplied LCA model is used to quantify the CO2 footprint of the production system for each scenario. By integrating Life Cycle Assessment and Multi-Criteria Assessment approaches, this study provides a comprehensive assessment method for identifying suitable industrial developments and quantifying the CO2 footprint improvements that might be achieved by their implementation. The results of this study emphasis, although by utilizing alternative fuels and more ecient production facility, it is possible to improve the CO2 footprint of clinker, radical improvements can be achieved on the portfolio level. Compared to Portland cement, very high reduction of CO2 footprint can be achieved if clinker is replaced with low carbon alternatives, such as Granulated Blast Furnace Slag (GBFS) which are the by-products of other  industrial production. Benchmarking a cement production system by its portfolio product is therefore a more reasonable approach, compared to focusing on the performance of its clinker production. This study showed that Industrial Symbiosis, that is, over the fence initiatives for material and energy exchanges and collaboration with nontraditional partners, are relevant to cement industry. However, the contingent nature of these strategies should always be noted, because the mere exercise of such activities may not lead to a more resource ecient production system. Therefore, in search for potential improvements, it is important to keep the search horizon as wide as possible, however, assess the potential improvements in each particular case. The comprehensive framework developed and applied in this research is an attempt in this direction.

A centralização da discussão da sustentabilidade e desenvolvimento sustentável colocou em evidencia conceitos como ecologia industrial oferecendo oportunidades e soluções para o desenvolvimento sustentável. Desta forma, este estudo apresenta como objeto central os eco-industrial parks que representam uma forma prática de aplicar o conceito de ecologia industrial. O objetivo deste trabalho foi identificar se e quais práticas de green supply chain management (GSCM) poderiam contribuir para a existência efetiva das características cooperação e integração entre empresas participantes de um eco-industrial park (EIP) e de outras características que determinam um parque como um EIP, visado o sucesso no desenvolvimento e operação desses parques ao longo do tempo. Para isso, foram realizadas duas revisões bibliográficas sistemáticas: a primeira referente à características de eco-industrial parks; a segunda sobre práticas de GSCM a fim de levantar na literatura as características de um eco-industrial park e as práticas de green supply chain management. Posteriormente, foram realizados três estudos de casos em parques que se nomeavam como eco-industrial park objetivando verificar a percepção de um EIP real além de analisar como os entrevistados relacionavam a contribuição das práticas de GSCM para a existência efetiva das características de um EIP levantadas por meio da revisão bibliográfica sistemática, podendo ser: contribuição forte, contribuição moderada e não existência de contribuição. Desta forma, constatou-se que poucas características de EIPs encontradas na literatura estão presentes nestes parques; as características comuns de EIPs presentes nos três casos são principalmente uso comum de serviço e infraestrutura e construção e arquitetura sustentável. Quanto à contribuição das práticas de GSCM para a existência das características de um EIP constatou-se que as práticas de GSCM denominadas \"comprometimento da alta gerência\" e \"suporte de nível médio\" são práticas que apresentam contribuição forte para a existência das onze características de EIPs encontradas na literatura revisada. Já as características de EIPs denominadas \"ciclo fechado\", \"empresas membros com certificação ambiental\" e \"simbiose industrial\" são as características que sofrem influência positiva do maior número de práticas de GSCM. Outra observação a ser feita é que somente a prática de GSCM denominada \"rotulagem ambiental\" não apresenta contribuição para a existência efetiva de nenhuma característica de EIP. / The centralization of sustainability and sustainable development discussion put in evidence concepts such as industrial ecology providing opportunities and solutions for sustainable development. Thus, this study presents as central object the eco-industrial parks that represent a practical way to apply the concept of industrial ecology. The objective of this study was to identify whether and which practices of green supply chain management (GSCM) could contribute to the effective existence of the characteristics cooperation and integration among participating companies an eco-industrial park (EIP) and other characteristics that determine a park like an EIP, aimed at the successful development and operation of these parks over time. For this, there were two systematic literature reviews: the first related to the eco-industrial parks characteristics; the second on GSCM practices in order to raise the literature the characteristics of an eco-industrial park and practices of green supply chain management. Subsequently, three case studies in parks that appointed them as eco-industrial park aimed to verify the perception of a real EIP were performed in addition to examining how respondents related the contribution of GSCM practices to the actual existence of the characteristics of an EIP raised by through systematic literature review and may be: strong contribution, moderate contribution and absence of contribution. Thus, it was found that few EIP features found in the literature are present in these parks; the common features of EIPs present in the three cases are particularly common use service and infrastructure construction and sustainable architecture. As for the contribution of GSCM practices for the existence of the characteristics of an EIP it found that the GSCM practices called \"top management commitment\" and \"midlevel support\" are practices that have strong contribution to the existence of the eleven features EIPs found in the reviewed literature. Already the EIPs features called \"closed loop\", \"member companies with environmental certification\" and \"industrial symbiosis\" are the features that suffer positive influence from as many GSCM practices. Another point to be made is that only the practice of GSCM called \"environmental labeling\" has no contribution to the actual existence of any characteristic of EIP.

Assim, torna-se necessário desenvolver indicadores de qualidade ambiental e de processo que sintetizem a situação organizacional refletindo barreiras e gargalos que podem impedir o desenvolvimento ambientalmente adequado do processo de obtenção de peças fundidas. Nesta Dissertação foi utilizada como objeto de estudo uma indústria de Fundição de pequeno porte com um programa de Produção mais Limpa (P+L) implementado. O presente trabalho tem como objetivo realizar avaliação do processo produtivo desta empresa com a intenção de quantificar e qualificar o movimento das principais matérias e energia ao longo das melhorias de P+L implementadas, considerando a reinserção dos mesmos no próprio processo, observando como as ferramentas de P+L podem valorizar e facilitar a utilização dos materiais e quais os benefícios ambientais e econômicos envolvidos. Desta forma, buscou-se criar indicadores que mostrem os benefícios da implementação da metodologia de P+L e sua relação com outras ferramentas complementares de sustentabilidade dentro do conceito de Ecologia Industrial, sendo capaz de tanto reduzir consumo de matérias primas e geração de resíduos, quanto de agregar valor aos resíduos inerentes ao processo. Os principais resultados obtidos foram os indicadores propostos que permitiram subsidiar as discussões sobre o andamento da parceria empresa/grupo de pesquisa e a sustentabilidade do processo de fundição em questão. Ao passo que a empresa segregou e qualificou seus resíduos, transformou-os em subproduto e coproduto para utilizá-los em seu próprio sistema produtivo, agregou um valor de difícil mensuração, porém extremamente significativo, já que envolveu o consumo destes materiais oriundos de um processo de produção em substituição ao consumo de recursos naturais, diminuindo assim a pressão sobre os ecossistemas naturais e aumentando a reciclabilidade de seus materiais e a produtividade de seu processo. / The foundry industry contributes to society by meeting the demand of production and recycling of metal parts, but has a range of environmental aspects by using significant quantities of raw materials extracted from the environment and produces a series of wastes that generate contaminants resulting environmental impacts. Thus, it becomes necessary to develop indicators of environmental quality and process that summarize the organizational situation reflecting barriers and bottlenecks which can prevent the development of environmentally appropriate process for obtaining castings. In this dissertation was used as study object a small foundry industry with a program of Cleaner Production (CP) implemented. The present work has as objective assessment of the production process of this company with the intent to quantify and qualify the movement of the main materials and energy along the CP improvements implemented, considering the reinsertion in the same process, noting how the CP tools can enhance and facilitate the use of materials and what the environmental and economic benefits involved. In this way the study aimed to develop indicators that show the benefits of implementing the CP methodology and its relationship with other complementary tools for sustainability within the concept of Industrial Ecology, being able to both reduce consumption of raw materials and waste generation, and to add value to the waste inherent to the process. The main results are the proposed indicators that allowed subsidize discussions about the progress of the partnership company / research group and the sustainability of the casting process in question. While the company segregated and qualified their waste, turned them into product and byproduct to use them in your own production system, has added value difficult to measure, but extremely significant because it involved the use of these materials from a production process to replace the consumption of natural resources, thus reducing pressure on natural ecosystems and increasing the recyclability of their materials and productivity of your process.

A sustentabilidade, por este motivo, necessita ser cada vez mais incorporada às atividades econômicas. A Ecologia Industrial e os Eco Parques, neste sentido, cumprem a tarefa de tornar as atividades econômicas mais sustentáveis através da aplicação de seus conceitos e ferramentas. Estes conceitos buscam fechar os ciclos produtivos o máximo possível, reduzir o consumo de materiais e energia e reduzir a geração de resíduos, efluentes e emissões. O Parque Tecnológico de São Leopoldo (TECNOSINOS) busca estabelecer diretrizes sobre a área de gestão ambiental de todas as atividades do parque, bem como das empresas que o compõe, criando e expondo todos os requisitos que deverão ser seguidos para implantar e manter o sistema e a política de gestão ambiental. O Eco Parque, um dos temas desse estudo e uma das ferramentas da Ecologia Industrial, pode auxiliar o TECNOSINOS a realizar estas melhorias ambientais e torná-lo mais sustentável. A construção de indicadores ambientais é necessária para avaliar o desempenho ambiental do parque após a implantação deste programa e quais os resultados que foram obtidos. Esta dissertação apresenta um estudo de caso no TECNOSINOS e tem como objetivo construir indicadores ambientais para avaliar o Programa Green Tech Park TECNOSINOS. A metodologia deste estudo compreende a aplicação do checklist do Programa Green Tech Park, e levantamento dos Níveis de Maturidade Ambiental das empresas em dois momentos (2013 e 2014) e avaliação dos ganhos ambientais obtidos durante o período. A seguir foi realizado um levantamento de aspectos e impactos ambientais e uma avaliação ambiental das empresas. Durante o ano de 2014 também foi realizada a aplicação de 10 indicadores ambientais em 15 empresas do TECNOSINOS e foi feita uma análise dos resultados obtidos. Foi identificado que 86% das empresas estão no Nível de Maturidade Ambiental I, 10% no Nível II e 4% no Nível III. Foram sugeridas melhorias para o TECNOSINOS em dois níveis: intrafirma e entrefirmas. Os indicadores ambientais aplicados nas 15 empresas mostraram que é necessário realizar várias ações de gestão ambiental nas empresas do parque para elevar os Níveis de Maturidade Ambiental. Os critérios de desempenho que necessitam ser aprimorados são Gestão, Investimentos, Ações Externas e Parcerias. Os indicadores ambientais utilizados identificaram ganhos importantes em pelo menos 3 empresas onde ações de gestão ambiental foram implementadas. Pode-se concluir que o TECNOSINOS está se consolidando com um Eco Parque do Tipo 3 (Entre firmas instaladas em Polos Industriais) em relação à organização das empresas e do tipo Sistema de Gestão Ambiental Integrado no que se refere ao tipo de trocas realizadas. / The reduced availability of natural resources and the environmental impacts caused by human activities have brought the need to make adjustments in them. Sustainability therefore needs to be increasingly incorporated into economic activities. The Industrial Ecology and Eco Parks, in this sense, fulfill the task of making the most sustainable economic activities by applying its concepts and tools. This concept search close their production cycles as much as possible, reduce the consumption of materials and energy and reduce waste generation and emissions. The Technological Park of São Leopoldo (TECNOSINOS) seeks to establish guidelines on the area of environmental management of all activities in the park, and the companies that comprise it, breeding and showing all the requirements that must be followed to deploy and maintain system and the environmental management policy. The Eco Park, one of the themes of this study and one of the Industrial Ecology tools can assist the TECNOSINOS to perform these environmental improvements and make it more sustainable. The construction of environmental indicators is required to assess the environmental performance of the park after the implementation of this program and what results were obtained. This dissertation presents a case study in TECNOSINOS and aims to build environmental indicators to assess the program Green Tech Park TECNOSINOS. The methodology of this study comprises applying the Green Tech Park Program’s checklist and survey of Environmental Maturity Levels of companies on two occasions (2013 and 2014) and assessment of the environmental gains made during the period. Next, it was conducted a survey of environmental aspects and impacts and an environmental assessment of the companies. During the year of 2014, it was also carried out the implementation of 10 environmental indicators in 15 companies in TECNOSINOS and an analysis of the results was made. It was identified that 86% of companies are in the Environmental Maturity Level I, 10% at Level II and 4% at Level III. Improvements were suggested for TECNOSINOS on two levels: firm level and inter-firm level. Environmental indicators applied in 15 selected companies showed that it is necessary to perform various actions of environmental management at the park's companies to raise the Environmental Maturity Levels. The performance criteria that need to be improved are Management, Investments, External Actions and Partnerships. The environmental indicators used identified important gains in at least 3 companies where environmental management actions have been implemented. It can be concluded that the TECNOSINOS is consolidating with an Eco Park type 3 regarding business organization and also, an Eco Park of Integrated Environmental Management System about the type of performed exchanges.
