Made available in DSpace on 2016-03-15T19:36:42Z (GMT). No. of bitstreams: 1 Celso Luchezzi.pdf: 3145897 bytes, checksum: 9bc68a1562b53f0848bb954c94689512 (MD5) Previous issue date: 2014-04-25 / The Construction is occupying its space industry and becoming a major industry on the national scene because its growth trend, driven by the Programa de Aceleração ao Crescimento (PAC), Minha Casa Minha Vida sponsored by Caixa Econômica, and also by the events of the World Cup in 2014 and Olympic Games 2016 in Rio de Janeiro. Due to these facts, there are initiatives for sustainable growth together with the National Solid Waste Policy, Law 12.305 , which is causing companies in the Construction sector begin to worry about the trash generated , giving due importance to recycling materials because these materials can generate many opportunities within the supply chain resulting from the revaluation of waste (rubble). Due to these facts, companies like Brazilian Associação Brasileira para Reciclagem de Resíduos da Construção Civil e Demolição (ABRECON), Estação Resgate, RMP Recicladora de Entulho e Recinert Abientale arise in the Brazilian market at the moment is no need to think of ways to sustainable disposal of waste (rubble) materials, who present solutions to recycling this waste (rubble) generated today. The challenge in this sector is to show the possibility of recycling materials and obtain financial and environmental gains preserving natural resources, not promoting accumulation of garbage in the works. The recycling of materials in Construction comes against the awareness of people involved in the generation of waste (rubble), in order to promote proper separation at source process, facilitating the work of collection and the consequent transformation into other products in order to reuse them within the production chain through structured Reverse Logistics. In this work, a case study was conducted in the works Construction, to identify the different types of waste generated, which will be classified and shown the possibilities for reuse, seeking their recycling. / A indústria da Construção Civil vem ocupando seu espaço e se tornando um setor importante no cenário nacional devido sua tendência de crescimento, impulsionada pelas obras do Programa de Aceleração ao Crescimento (PAC), programa Minha Casa Minha Vida patrocinando pela Caixa Econômica, e também pelos eventos da Copa do Mundo em 2014 e os Jogos Olímpicos em 2016 no Rio de Janeiro. Devido a estes fatos, surgem iniciativas de crescimento sustentável juntamente com a Política Nacional de Resíduos Sólidos (PNRS), a Lei 12.305, que está fazendo com que as empresas do setor de Construção Civil comecem a se preocupar com o lixo (entulho) gerado, dando a devida importância à reciclagem de entulhos, pois estes materiais podem gerar muitas oportunidades dentro da cadeia produtiva decorrente da revalorização dos resíduos. Devido a estes fatos, empresas como a Associação Brasileira para Reciclagem de Resíduos da Construção Civil e Demolição (ABRECON), Estação Resgate, RMP Recicladora de Entulho e Recinert Abientale, surgem no mercado brasileiro no momento em que há necessidade de se pensar em formas de descartes sustentáveis, de materiais e ou de resíduos da Construção Civil, sendo que hoje elas apresentam soluções para reciclagem desse lixo (entulho) gerado. O desafio desse setor é mostrar a possibilidade de reciclar materiais e obter ganhos financeiros e ambientais preservando recursos naturais, não promovendo acúmulos de lixo nas obras. A reciclagem de materiais na Construção Civil vem de encontro à conscientização das pessoas envolvidas no processo de geração do lixo (entulho), com o intuito de promover a separação correta na fonte geradora facilitando o trabalho de coleta e, consequente, transformação em outros produtos de forma a reutilizá-los dentro da cadeia produtiva da Construção Civil através de uma Logística Reversa estruturada. Neste trabalho foi realizado um estudo de caso em obras da Construção Civil, visando identificar os diferentes tipos de resíduos gerados, os quais devem ser classificados e mostrados as possibilidades de reuso na Construção Civil, visando sua reciclagem de modo a criar oportunidades na cadeia produtiva.

Designing an efficient Collection process for Discarded furniture

Liao, Yin January 2017 (has links)
The furniture industry is a thriving industry in the past decades all over the world. The increase in production and sales of furniture products means that more raw materials are needed and more furniture waste is produced at the same time. Taking into account the unsolved environmental issues, it is necessary to make innovation changes to reduce the waste and overcome the continuously increasing resource consumption. Circular economy draws a wide attention under this situation. As an alternative to replace the traditional linear consumption model, it balances the economic development and environmental concern. Turning waste into a new resource is a profitable opportunity for the furniture industry. However, product recovery in this industry meets obstacles due to the character of the furniture.This study considers discarded bulky furniture products. It focuses on the first step of furniture waste recovery: the collection process. The aim of this research is improving the efficiency of a “many to one” collection process in a reverse logistics system and increasing the recovery level within the hierarchy of options for discarded furniture. By using the soft system methodology, this study explores the current discarded furniture collection situation within Europe and then analyzes each essential element of this collection system. After that, combining with the relevant circular economy theory and information gathered from a case furniture company, we design a new conceptual business process model for discarded furniture collection.In the newly designed model, the collection process is carried out by the individual transport option with sufficient capacity from customer’s home to the furniture store. The new model is based on a collaborative lifestyle information platform. By managing the real-time information, the platform aligns individuals’ transport resources with discarded furniture demand to reduce the transport cost of the collection process. This model aims for optimal use of the available individual resources to complement the transport process. Moreover, this information platform helps to collect information in the early stage to reduce the uncertainty of reverse logistics.

Submitted by Nadir Basilio (nadirsb@uninove.br) on 2017-08-04T21:42:15Z No. of bitstreams: 1 Jose Manuel Ferreira Correia.pdf: 1209660 bytes, checksum: 3666126b31bb24d1952391d308ba7045 (MD5) / Made available in DSpace on 2017-08-04T21:42:15Z (GMT). No. of bitstreams: 1 Jose Manuel Ferreira Correia.pdf: 1209660 bytes, checksum: 3666126b31bb24d1952391d308ba7045 (MD5) Previous issue date: 2017-02-14 / The Brazilian government promulgated the national solid waste policy through law 12,305 / 2010, which encourages construction industries to adopt Reverse Logistics practices for the management of solid waste. However, construction industries suffer barriers to the implementation of Reverse Logistics. The objective of this research is to evaluate the barriers that impede the more effective adoption of Reverse Logistics practices in Brazilian construction industries. The research method used was a bibliometric and systematic review about the theme Reverse Logistics in civil construction to identify the variables for the elaboration of the research instrument. The face test was then performed with three specialists for validation. Subsequently, the survey method was applied (104 questionnaires). The results of this study add in the existing researches, through a multivariate analysis of the data making possible the managerial decision making and confirmed that the barriers impede the more effective adoption of Reverse Logistics practices. These industries have difficulties in investing in infrastructure resources, in quality management system (ISO 9001) and In the training of its employees, which affects the understanding and the organizational understanding for the elaboration of projects, which include the principles of Reverse Logistics, such as: the study of collection points, life cycle analysis and mass balance evaluation. With this there is no the development of organizational structure, which compromises the hiring of specialized managers and a better evaluation of logistics operators. In addition, the lack of knowledge about obtaining credit lines and government regulatory incentives increases its operational costs and generates an unfavorable organizational culture. On the other hand, the adoption of Reverse Logistics practices promotes the improvement of its processes of selective demolition and waste management. In this way the industries obtain economic, environmental and social gains by the best use of recovered materials and recycled and by the decrease of the generated amount of waste for the discard. / O governo brasileiro promulgou a política nacional de resíduos sólidos por meio da lei 12.305/2010, que impulsiona as empresas de construção à adoção de práticas de Logística Reversa para a gestão dos resíduos sólidos. Porém, as empresas da construção civil sofrem barreiras para a implantação da Logística Reversa. O objetivo dessa pesquisa é avaliar as barreiras que dificultam a adoção mais efetiva das práticas de Logística Reversa nas empresas brasileiras construtoras de edificações. O método de pesquisa utilizado foi revisão bibliométrica e sistemática acerca do tema Logística Reversa na construção civil para identificar as variáveis para a elaboração do instrumento de pesquisa. Em seguida foi realizado o teste de face com três especialistas para a sua validação. Posteriormente foi aplicado o método survey (104 questionários). Os resultados desse estudo acrescentam nas pesquisas existentes, por meio de analise multivariada dos dados possibilitam a tomada de decisão gerencial e confirmaram como as barreiras dificultam a adoção mais efetiva das práticas de Logística Reversa. Estas empresas possuem dificuldades em investir em recursos de infraestrutura, em sistema de gestão de qualidade (ISO 9001) e no treinamento de seus funcionários, o que afeta a compreensão e o entendimento organizacional para a elaboração de projetos, que incluam os princípios da Logística Reversa, tais como: o estudo dos pontos de coleta, analise do ciclo de vida e avaliação do balanço de massa. Com isso não há o desenvolvimento de estrutura organizacional, o que compromete a contratação de gestores especializados e de uma melhor avaliação dos operadores logísticos. Além disso, o desconhecimento para a obtenção de linhas de crédito e incentivos regulatórios governamentais encarecem seus custos operacionais e geram uma cultura organizacional desfavorável. Por outro lado, a adoção de práticas de Logística Reversa promove a melhoria de seus processos de demolição seletiva e gestão de resíduos. Desta maneira as empresas obtêm ganhos econômicos, ambientais e sociais pelo melhor aproveitamento dos materiais recuperados e reciclados e pela diminuição da quantidade gerada de resíduos para o descarte.

Reverse Logistics Management in Construction : A multiple case study examining the effect of organisational size

Gustafsson, Jonatan, Bengtsson, Linnea January 2020 (has links)
Background: Increasing awareness for the environmental impact, governments and higher authorities has in the past years issued regulations for waste creation and management, creating a need for new practices and policies on how used material is handled. Reversed logistics could simply be described as the process of ensuring value creation spanning over the entire life cycle. The importance to understand and clarify what differences and limitations the adaptation of reverse logistics in the construction industry present, depending on organisation size.  Purpose and research questions: The purpose with this research is to compare how SMEs and large organisations in the construction industry adapt reverse logistics practices. In order to fulfil the purpose two research questions are designed. The first question process what the major differences are between SMEs and large organisations regarding the willingness to adapt reverse logistics. The second question process what the major differences are between SMEs and large organisations regarding the ability to adapt reverse logistics. Method: This research used a qualitative approach. A literature review was conducted to construct a theoretical framework. Ten interviews are conducted with SMEs and large organisation within the construction industry as well an intermediary from a demolition organisation. The interviews are conducted in a semi-structural manner. The interviews are coded in order to define themes and construct a framework. Conclusion: The willingness to adapt reverse logistics depend on the responsibilities the companies have. The larger organisations are willing in order to fulfil larger environmental goals and regulations in the industry whereas SMEs want to ease daily operations and do good to the adjacent community. The ability to adapt reverse logistics are affected by the resources and regulations. SMEs have difficulties in adapting reverse logistics fully because of limited resources relating to handling and storing the to-be-reused material. The larger organisations have the resources but a longer implementation route and with larger projects need the clients demand to adapt reverse logistics on project scale.

The Customer Experience in the Product After-Use Phase : A case study of the IKEA second-hand store

Garcia, Viviana January 2021 (has links)
As customers become more and more aware of the threats and limits of the current economic system, joined with the pressure of environmental policies, companies are pressured to rethink their offerings, processes, and business models in order to accelerate the transition to a circular economy. This transition requires significant changes in habits and behaviors, but simultaneously it offers opportunities for innovation. In this regard, business model innovation plays an essential role in enabling this transition via circular business models that close the loop. For the successful development, implementation, and adoption of new business models, a depth understanding of customers' needs is fundamental. However, little is known about the customer perceptions, motivations, and willingness to participate in circular economy. To address this gap, the study explores the transition to circular economy from the customers' perspective by employing a qualitative single case study bounded to the furniture retail company, IKEA, specifically the IKEA Second-Hand pilot store in Eskilstuna, Sweden. Through in-person interviews, observations, and a questionnaire, data from customers donating their used furniture to the recycling mall ReTuna, people discarding furniture at the recycling station, and people selling and giving away their used furniture via the social media platform Facebook, was captured to explore the customer experience in the after-use phase of furniture. Findings of the study present opportunities for the case company to strengthen its product recovery strategies.

The Reverse Supply Chains of the Fast-Moving Consumer Goods : The Impacts of Product Returns on Reverse Supply Chains in Sweden

Dachan, M. Hassan, Sherif, Shengyun January 2023 (has links)
The unceasing ambition of companies to enhance their profitability, capture novel markets, and address the diverse and evolving needs of customers has led to an irrational surge in production and the exploitative depletion of natural resources. This unwarranted increase in production has, in turn, been accompanied by a rise in product returns by consumers, which, upon reverting to their original sources through the supply chain, has compounded the complexities of the supply chains and precipitated new pressures and burdens on the companies and their supply chains, necessitating their adept management. Likewise, the fast-moving consumer goods sector (FMCG) in Sweden has been experiencing an increasing number of product returns, which is a significant concern for both manufacturers and retailers. This thesis aims to investigate the drivers of product returns and their impact on the existing B2B supply chains to provide recommendations for reducing their impact and frequency. The research methodology includes a review of the previous scientific literature related to the topic, participant observations, and semi-structured interviews with key stakeholders in the industry. A qualitative approach has been adopted using a case study method, and thematic analysis was utilized. The results show that the main drivers for product returns between businesses in the Swedish FMCG sector are quality, contracts, customer service, and legislation, all of which contribute to disruptive effects within the existing B2B supply chains. Furthermore, the study reveals four types of disturbances associated with product returns, including logistical, sustainability, operational, and cost and value-related disruptions. This thesis provides insights into the challenges and opportunities associated with product returns in the Swedish FMCG sector and highlights the need for suppliers to adopt a proactive approach to managing returns to remain competitive in the market.

A Simulation-Based Decision Support for Reverse Logistics of Remanufactured Spare Parts : A Case study of Diesel Particle Filters

Tryggvadottir, Thordis January 2023 (has links)
Remanufacturing plays a crucial role in circular business models as it offers a sustainable approach to restoring products while reducing energy and resource consumption. In the automotive industry, remanufactured parts are widely used for spare parts, although their usage is still limited compared to newly produced parts. While remanufacturing is considered environmentally beneficial, it is essential to take into account the impact of reverse logistics practices when assessing the environmental and economic effects of remanufactured parts. This research aims to develop a simulation-based decision support tool for assessing Scania’s aftermarket operations. It evaluates the environmental and economic impact of using remanufactured spare parts compared to newly produced ones. Using agent-based and discrete event methods, the simulation model analyzes the effectiveness of the reverse logistics network in terms of CO2 emissions and cost. The findings highlight the benefits of remanufacturing in terms of cost, CO2 emissions, and material savings compared to new production. These findings support the integration of remanufactured parts into the industry’s circular practices. It enables waste reduction, extends the lifespan of products, and contributes to overall sustainability efforts. The simulation model developed in this study can serve as a valuable tool for decision-makers seeking to evaluate the environmental and economic implications of using remanufactured spare parts.
