General Scope

Several factors have led to an increase in the focus on sustainable development. In this context, the concept of Circular Economy (CE) has gained tremendous momentum in research and implementation. Fitted into CE’s concept, the Life Extension Strategies (LES) have been popular among industrial practitioners, regulators, policymakers, and academics from different industries due to the several benefits of these strategies. The general scope of this study is to approach LES within the industrial environment. The main goal is to understand how Remanufacturing and Refurbishment (R/R) strategies have been applied in different industry types. To achieve this goal, we carried out a systematic literature review whereby we captured some examples of R/R applications that demonstrate the potential of application to various industries (e.g., aerospace/aeronautics, energy power, and automotive industries) and equipment types (e.g., nuclear reactor, hydropower plant, and turbine blades). We also described some strategies to implement LES (e.g., economic analysis and life cycle assessment) and the different impacts achieved or expected (life extension, cost-saving, and efficiency enhancement). Moreover, we discussed three specific points concerning R/R application, the LES categorization, and the inexistence of a multi-dimensional framework to LES. Finally, we provided a set of systematized information about R/R.

Nowadays, it is possible to buy clothing using online platforms, either by accessing online brand stores, general online stores or circular economy platforms. This paper presents a study on mobile applications that support online commerce for clothing, focusing on the review of the mobile applications with features that are characteristic of the circular economy paradigm. Findings include the fact that almost all the mobile applications analysed have pictures illustrative of the clothes and accessories that are available for trading as well as their brief description. Furthermore, this paper presents a study of various scientific articles about the circular economy of clothes and how it can be beneficial to the future of the environment. It is a junction with a Web platform for its growth and its disclosure. The paper builds conclusions upon the assumption that the circular economy is a growing business that is part of a sustainable development where the main goal is to reduce the environmental impact. The paper proposes the analysis of an innovative taxonomy of mobile applications about the circular economy.

First Time

For the first time in the scientific literature, this research shows an analysis of the implementation of circular economy techniques under sustainable development framework in six municipalities with a depressed economy in Colombia. The analysis is based on solid waste data production at a local scale, the valuation of the waste for subsequent recycling, and the identification and quantification of the variables associated with the treatment and final disposal of waste, in accordance with the Colombian regulatory framework. Waste generation data are obtained considering three different scenarios, in which a comparison between the simulated values and those established in the management plans are compared. Important differences have been identified between the waste management programs of each municipality, specifically regarding the components of waste collection, transportation and disposal, participation of environmental reclaimers, and potential use of materials. These differences are fundamentally associated with the different administrative processes considered for each individual municipality. This research is a good starting point for the development of waste management models based on circular economy techniques, through the subsequent implementation of an office tool in depressed regions such as those studied.

AbstractThe implementation of circular economy in wood industries is an effective way for future sustainable development. The wood industries in China are not in the direction of circular economy approach due to less availability of assessment/calculation data of pollutants as per life cycle assessment (LCA) criteria. The present study focuses on the calculation of emission and pollutants from wood industries as per LCA; the emission and pollution data were collected from fiberboard Medium-density fiberboard (MDF), plywood and particleboard (PB) production. The comparative analysis of dust emissions, industrial waste gases and chemical oxygen demand (COD) were performed among three wood industries. The results revealed that the fiberboard industry was the highest emitter of dust, industrial waste gas and COD; and particleboard industry was the least emitter. Further, results indicated that pollutant index of wood industries were significantly changed between 2015 and 2017; the industrial waste water discharge increased five folds and the COD, dust and industrial gases increased two times. This study provides with the emission and pollutants data of wood industries as per LCA to promote the sustainable development for circular and low carbon economics.

Sustainable Future

The increasingly stellar attraction of the digital technologies and the growing, though not universal, consensus of the need to build a sustainable future, are two powerful trends within society. The aim of this article is to offer an exploratory review of how the leading companies within the digital transformation market have addressed sustainable development. As such, the article’s originality and value lie in offering a review of current corporate thinking within that market. The study adopts an inductive, qualitative approach based on an examination of published company reports, and identifies six major sustainability themes being actively promoted and supported. The article concludes that the current sustainability objectives of the technology companies are driven as much by commercial reality as any altruistic motives, and that support and promotion of the circular economy may offer the best opportunity for digital technologies to meaningfully impact sustainable development.

Multiple Uses

A new movement in urban environmental policy, the circular economy (CE), aims to change how Europeans consume and produce materials and energy. Cities are taking up the CE challenge. This research inquires whether the infant CE programs in European cities include cultural heritage and adaptive reuse of cultural heritage (ARCH) buildings. ARCH buildings exemplify the central principal of the CE, which is a temporally long service life with multiple uses for several generations of users. In addition, culture and cultural heritage buildings are established drivers of socioeconomic development, urban landscape, and identity. Hypothetically, cultural heritage and adaptive reuse of cultural heritage (ARCH) buildings should be prominently included in European cities’ CE programs, particularly those cities that are highly ranked on the 2019 European Cultural and Creative Cities Monitor (Monitor). To test this hypothesis, this study creates a novel dataset that profiles the existing circular city plans of 190 European cities included in the Monitor’s ranking. Contrary to the hypothesis, just seven percent of cities in the dataset include cultural heritage. European cities are missing an opportunity to achieve their CE goals and preserve their unique identities as embodied in the built environment.
