Over the last decade, the concept of the circular economy (CE) has gained momentum among practitioners, politicians, and scholars because of its promise of achieving sustainability goals. However, there is still a need to demonstrate and assess the positive environmental impacts of the CE. With respect to the building sector, the CE is still a relatively new topic. To date, research has tended to focus primarily on the macro-scale (cities or eco-parks) and the micro-scale (manufactured products or construction materials). Nevertheless, the often- neglected built environment is also expected to play a crucial role in the transition towards a CE due to its high contribution to various environmental burdens. This paper contributes to this growing area of research by reviewing four cases of ‘circular neighbourhood’ projects in Europe. First, a conceptual framework analysis is defined and applied to the cases. Second, CE initiatives and actions are identified and classified using interviews and document analysis. Third, the use of assessment tools within these CE projects is investigated. The results demonstrate a diverse representation of the CE paradigm and the growing role played by the assessment tools.

This chapter focuses on the metabolic concept for the management and treatment of construction waste and organic fraction of municipal solid waste in urban areas. Analysis of related Dutch, German and Polish guidelines for environmental zoning of industrial plants, allows formulation of conditions for an optimal siting of waste infrastructure within urban unit. Protection zones are defined in accordance with specific requirements for waste facilities, which treat and recycle both municipal and construction waste. Distances from inhabited areas are related to environmental burdens generated by such facilities (incl. parameters such as odours, noise level, explosion impacts and emissions of other substances). Moreover, this chapter provides the analysis of a selected case studies of waste facilities processing. A comparison of European guidelines and implementation of practical solutions is described in the case study analysis, including the issues open for the discussion about sustainable siting for waste processing infrastructure within an urban unit.

O presente artigo é resultado de uma investigação a respeito da avaliação da aprendizagem no âmbito do ensino de Química, por meio de um estudo de caso. Mais especificamente, foi analisado o processo avaliativo de um professor que atua na disciplina de Química em um curso Técnico Integrado ao Ensino Médio de uma Instituição Federal de ensino. O estudo tinha como objetivos investigar, na prática do professor objeto de estudo, indícios de avaliação como oportunidade de aprendizagem e discutir possibilidades para utilização de instrumentos de avaliação nessa perspectiva. O estudo teve caráter qualitativo e contemplou observações de aulas, entrevista e acompanhamento em campo. Como principais resultados, apontamos indícios de avaliação como oportunidade de aprendizagem nas práticas avaliativas do professor, identificados a partir de três vertentes: concepções de avaliação, instrumentos utilizados e ações do professor.   Palavras-chave: Avaliação da Aprendizagem Escolar. Avaliação como Oportunidade de Aprendizagem.

More specifically, we analyzed the assessment process of a teacher who works in the discipline of Chemistry in an Integrated Technical High School course of a federal teaching institution. The objectives were to investigate, in the practice of the teacher object of study, evidence of assessment as an opportunity for learning and to discuss possibilities for the use of assessment tools in this perspective. The study had a qualitative character and contemplated observations of lessons, interview and follow up in the field. As main results, we point out evidence of assessment as an opportunity for learning in the evaluation practices of teachers, identified from three perspectives: teacher conceptions in relation to assessment, instruments used and teacher actions.   Keywords: Assessment of School Learning.

More than 95% of multi-story residential buildings in Austria are currently predominantly constructed with conventional mineral construction materials. This fact combined with the increasing demands for a healthy residential living atmosphere demonstrates the great potential for using ecological materials. Life cycle assessments provide information on the ecological performance of buildings, but the corresponding economical aspects are not considered. Nevertheless, the economic aspects of a certain draft are important to clients and designers. Therefore, simplified assessment-tools are needed that take into account the ecological impact as well as the building costs. This paper presents the results of an investigation supplemented by a case study of a multistory residential building, which was finished 2016 in Austria, illustrating the differences between the state-of-the-art material selection and ecologically optimized alternatives. The ecological impacts and the costs for the selected building-system were determined based on the case study. Subsequently, ecological optimization potentials were identified according to the environmental indicator OI3. Finally, the effects on component and construction costs were evaluated. The steps of this simplified process reveal the interdependency between ecological aspects and the costs of materials. This procedure represents a decision-making tool that can be used by clients as well as designers. The results of this research emphasize the large environmental impact improvements with little expenses when implementing sustainability in multi-story residential buildings as a crucial part of a green design.

Context Specific

Urbanization causes massive flows of construction materials and waste, which generates environmental impacts and land-use conflicts. Circular economy strategies at a local scale and in coordination with urban planning could respond to those issues. Implementing these strategies raises challenges as it requires a better knowledge of flows and their space-differentiated drivers. This article focuses on the case of the Paris region (Ile-de-France) in 2013. Construction materials inflows and outflows to and from anthropogenic stocks of buildings and networks are estimated and located though a bottom-up approach based on the collection and processing of geolocalized data. Flow analysis focuses on the relationship between urbanization and flows with a view to establishing context-specific circular economy strategies. Results show that regional inflows of construction materials to stocks in 2013 reach between 1.8 and 2.1 t/capita while outflows are between 1.0 and 1.5 t/capita. Both inflows and outflows are mainly driven by building construction and demolition as well as by road renewal. The region is composed of three sub-urban areas and flows per capita in the dense central city of Paris are significantly lower than in the low-density outskirt area of Grande Couronne (GC). Road renewal accounts for a larger share of flows in GC. Future research will address methodological limits.

Management Case Study

The transition to circular economy models is a big challenge for enterprises, since it forces them not only to change established supply chains, pay extra attention to the quality and durability of manufactured products, develop schemes for the collection and subsequent disposal of products that have worked out their life, but also actively develop eco-innovation activities and participate in R&D more actively. The aim of this work is to study examples of the implementation of circular business models from the leading EU-based companies. The focus of the research on European companies is due to the fact that the European Union has been implementing a plan for the transition to a circular economy since 2015. In order to track the nature of applied eco-innovation in the field of CE the case-studies from the leading EU-based companies have been analysed. The choice of the companies is determined by their commitment to the CE principles and availability of the obtained results in their annual reports. The case-studies have shown all reviewed companies demonstrated beyond average commitment to the principles of CE in all aspects (sayings, doings and materiality). Their strong adherence is determined by their intense environmental impact and leading positions at regional and global markets.
