This article aims to investigate the role of waste management in the development of modern green and smart cities and to determine the existence of several key points in programs transforming cities into green cities with smart technologies. The relevance of the research is determined by the need to develop a theoretical and methodological basis for the green and smart city concepts. The research process involved the following methods: Scientific analysis, comparison, and synthesis. The research results of the case study of Russia determined that for urban territories with great distances between urban districts, waste sorting stations should be located as parts of so-called waste recycling complexes at intermunicipal landfills. This will allow a more fully implementation of the concept of recycling economy not only in Russian cities, but also in other cities with sparse populations across the world. Further, the authors conclude that the effectiveness of green technologies in modern cities, especially in waste management, depends on the level of participation of citizens. People are active participants in the life processes of cities and have a direct impact on the urban environment. Consequently, the introduction of green technologies can only be achieved in harmony with the well-established behavioral attitudes of city residents together with the implementation of green and smart urban technologies.

Textile recycling can save resource and energy, as well as make huge economic benefits. Under the background of recycling economy, it is imperative to build textile recycling and reuse system in China, as there are many problems in Chinese textile waste recycling market. This paper introduces the background of textile waste recycling and explores the detail of advanced textile recycling mode in Germany as a case study, through which the author points out that we can learn from the German mode and choose Yangtze River Delta as a pilot area to establish the textile waste recycling system.

This study analyzes various regulations on urban waste management, with emphasis in recycling activities. How regulatory frameworks from the national level translates to the city level, and the extent of its implementation are examined through field observations in the city of Semarang as a case study. Based on the study of regulations and policy documents, this study suggests that recycling is found in various policy domains, not only those concerning waste management but also in the environment, industry, company’s limited liability and infrastructure domains. This study highlights two main problems in recycling namely: policy idealism and approach dualism. From these two basic problems, this study recommends a strategy for strengthening the capacity and collaboration of related parties as one of keys to increasing the capacity of waste recycling, especially in urban areas in Indonesia.

Abstract Modern cities face many challenges related to globalisation, metropolisation and digitalisation. The smart city concept, which has been gaining popularity in recent years, is considered an answer to their needs. One of the paradigms of modern smart cities is the Internet of Things. This article aims to identify the main research directions and trends in the scientific literature in the field of Internet-of-Things-based smart cities. The author of the paper conducted a bibliometric analysis of publications from 2012–2021, collected from the Web of Science, Scopus and IEEE Xplore databases. The methodology includes: (i) the selection of databases and key words, (ii) defining search criteria, (iii) data export, creation of an aggregate database and record selection, and (iv) the analysis of the results and identification of the major research trends. The study involved 1019 publications. The last stage of the research process identified the leading countries, institutions, journals, and authors in terms of publication activity, as well as the most frequently occurring terms. The key word analysis allowed identifying five main research directions: IoT application domains in smart cities, IoT architecture for smart cities, energy, security and privacy and data. Within each area, the main research themes have been identified, and selected publications have been reviewed.

Modern cities are changing to become more reliant upon technology for better personal, social, and economic outcomes for all citizens. The core of enabling a smart city plan relies on a comprehensive understanding of its drivers and technological aid requirements. Hence, technology roadmapping as one of the most effective approaches need to be considered to aligning the smart cities strategies with planning in the field of technology, while the focus on the most technology roadmapping studies has been limited to the development of industrial technology and product development. Thus, to support the achievement of the smart cities, this study aims to adapt and utilise Strategic Technology Alignment Roadmapping (STAR) methodology to guid and justify investment in smart city’s R&D projects to achieve the optimum project portfolio. The method is tested in a real case study, which shows how STAR methodology can be effective to implement throughout the worldwide smart cities development to support strategic technology investments.

Urban mining by recyclers represents a positive environmental impact as well as being part of the waste management chain. This paper analyzes the contribution of waste pickers in the city of Cuenca in Ecuador and the conditions of their activity. This research has a two-fold objective. First, it calculates the reduction of greenhouse gas emissions resulting from the substitution of virgin raw material in the production process by using recycled urban waste. The second objective is to conduct a socioeconomic analysis of the workers involved in the urban waste sector. Cuenca (Ecuador) is the main city used for this case study, thanks to the accessibility of a rich database built from the survey conducted by the NGO Alliance for Development. The information contained in this survey facilitates the identification of potential consumers of the waste industry. This study uses Clean Development Mechanism methodology. Finally, this work proposes a theoretical model for solid waste management, applied to the city, following the principles of the circular economy.

This paper presents the evaluation of usersХ experiences in three intelligent lighting pilots in Finland. Two of the case studies are related to the use of intelligent lighting in different kinds of traffic areas, having emphasis on aspects of visibility, traffic and movement safety, and sense of security. The last case study presents a more complex view to the experience of intelligent lighting in smart city contexts. The evaluation methods, tailored to each pilot context, include questionnaires, an urban dashboard, in-situ interviews and observations, evaluation probes, and system data analyses. The applicability of the selected and tested methods is discussed reflecting the process and achieved results.
