La creciente preocupación por el aumento del tamaño de las ciudades y su consiguiente generación de desechos, hace necesario una gestión sostenible de desechos. El objetivo de este artículo es analizar la rentabilidad económica del reciclaje de desechos textiles en dos ciudades del Sur de Chile: Temuco y Puerto Montt. Como metodología se realizará un presupuesta de capital y flujo de caja para evaluar el valor actual neto y la tasa interna de retorno de la inversión en los escenarios de reciclaje en cada ciudad. Los resultados indican que es más rentable realizar la instalación de una planta de reciclaje en Temuco que en Puerto Montt analizando los escenarios. Se concluye que existe una relación positiva entre la cantidad de habitantes de la ciudad y los ingresos percibidos en el reciclaje textil.

Poor public health is always associated with the mismanagement of municipal solid waste (MSW). Many cities are besieged by MSW in the world. It is essential to do a good job in MSW management (MSWM). In order to improve the efficiency of MSWM, the Chinese government has intensively implemented relevant policies. There are still few studies on MSWM efficiency in China. The research aims to comprehensively analyze MSWM efficiency, find high-efficiency MSWM policy implementation routes and the breakthrough on improving MSWM efficiency. To measure Chinese MSWM efficiency accurately, this paper introduced the three-stage data envelopment analysis (DEA) model into the research. According to the results of DEA, Fuzzy c-Means algorithm was used to the cluster analysis of 33 typical cities. After eliminating the interference of the external environment and random disturbance, the mean value of MSWM efficiency declined from 0.575 to 0.544. The mean of pure technical efficiency (PTE) was decli...

The current crisis dominates everything from health to day-to-day life. But it will pass over within a relatively short space of time and the economic recession seems likely to reverse the long-standing pattern. Given the gravity of the circumstances, nations have been constrained to undertake unusual approach arrangements. This article proposes a framework of the COVID-19 effect following analysis and comparison of the most prominent concepts of the public health and circular economy. Our paper helps to identify the positions of each of these concepts with regard to public health, environmental sustainability and economic growth. This study enriches the literature on the environmental sciences and public health by providing analysis of the effects of the policies. Finally, this article recognizes that there must be local action priorities that allow for small and sequential wins in economic, health and environmental aspects in the territory.

§I. CONTEXTE PNR — Le projet scientifique accompagne une demarche de gouvernance territoriale (la mise en operation de la nouvelle Charte PNR) qui se veut exemplaire en termes d’un developpement territorial respectueux des normes de la soutenabilite. Ce module va situer le projet scientifique par rapport aux enjeux, ambitions et procedures affiches par les acteurs du Parc Naturel Regionale de la Haute Vallee de Chevreuse en Ile‐de‐France. §II. ETAT EMPREINTES — Revue approfondie de la litterature recente (en anglais et francais), empirique et conceptuelle, sur le concept de l’empreinte ecologique, ses usages, ses points forts et ses limites. §III. METHODOLOGIE — Exposition detaillee des conventions de collecte de donnees et d’estimation des indicateurs agreges des « pressions » environnementales sur le territoire du Parc. Cette exposition va s’appuyer directement des resultats des modules §I et §II et, devrait s’adresser plus particulierement a des questions cles pour l’application envisagee au PNR Chevreuse, a savoir : les echelles territoriales d’une empreinte, le traitement des usages ‘directs’ et ‘indirects’ de l’environnement et des « flux » a travers la frontiere du territoire cible, et la complementarite entre ‘top‐down’ demarches moyennant coefficients Inputs/Outputs etablis aux echelles superieures et ‘bottom‐up’ demarches moyennant des donnees du PNR lui‐meme. §IV. SCHEMA DONNEES — Mise en place [par adaptation du KerBabel™ Indicateur Kiosk, KIK] d’un systeme interactif en ligne de meta‐informations pour le catalogage des donnees et des indicateurs composites susceptibles d’etre mobilises dans l’estimation des indicateurs agreges du type Empreinte Ecologique pour le PNR. Ce systeme devrait, parmi d’autres roles, permettre de situer des donnees sur les pressions environnementales par rapport a des causes du cote de l’economie [en 6 branches majeures], par rapport a l’etat de l’environnement [en 7 branches], et sur le plan spatial [territoire du PNR, espace francilien, France, Europe, echelle planetaire]. §V. Travail par SECTEUR ECOLOGIQUE — Ce module assurera l’identification et catalogage d’une diversite representative d’indicateurs (qui peuvent etre physiques et monetaires) pour chaque « case » ou categorie de pressions definie par l’interface entre branches majeures d’activite economique et composantes majeures de l’environnement. Ensuite, sur cette base, il va produire des premieres estimations pour des indicateurs synthetiques par categorie de pressions. §VI. Indicateurs Agreges de performance et de durabilite — Ce module va definir et demontrer des procedures d’estimation empirique d’une « Empreinte Ecologique » pour le territoire du PNR Chevreuse. Il va expliciter les conventions sous‐jacentes aux procedures d’estimation et, par le biais des tests de sensibilite, mettre en evidence (1) les options pour l’integration des flux a travers la frontiere du Parc et (2) les incertitudes associees a ce genre d’indicateur agrege. §VII. BONS USAGES de l’Empreinte Ecologique — Ce module va demontrer des roles pour les calculs d’une Empreinte Ecologique pour informer les debats et les strategies pour la gouvernance du PNR, par exemple, dans des demarches de veille, d’evaluation et de communication autour des projets et politiques de developpement territorial. Il va fournir des conseils pour des futurs producteurs et utilisateurs des estimations d’Empreinte Ecologique sur (1) la preparation et l’interpretation des « profils KQA (Controle la la Qualite de la Connaissance » concernant les incertitudes et (2) les determinants de la pertinence et des limites de l’Empreinte Ecologique comme indicateur agrege de la performance economique et environnementale d’un territoire. §VIII. Documentation et Dissemination — Activites permanentes et periodiques de documentation et de dissemination des methodes et des resultats ; exploitation des technologies Internet pour permettre a une communaute large de scientifiques et d’eventuels utilisateurs de decouvrir et contribuer aux deliberations sur les estimations et leurs usages.

The current crisis dominates everything from commerce to day-to-day life. But it will pass over within a relatively short space of time and the recession seems likely to reverse the long-standing pattern. Given the gravity of the circumstance, nations have been constrained to undertake unusual approach arrangements. This article proposes a framework of the COVID-19 effect following analysis and comparison of the most prominent concepts of the economic crisis and devaluation. Our paper helps to identify the positions of each of these concepts with regard to the balance trade and Argentina prosperity. This study enriches the literature on the Marshall-Lerner condition and J-curve effect by providing analysis of the devaluation scenario. Finally, areas of application and policy implications of the COVID-19 effect are explored in order to guide future research on the developing countries.

The growing concern over the change in climatic conditions and the management and conservation of biological resources makes it necessary to create models suitable for the sustainable management of these resources. The bioeconomy suggests a model based on the production of renewable biological resources and the conversion of these resources into value-added products. The main aim of this article is to assess the impact of the bioeconomy on the scholar. This manuscript also aims to continue and update this discussion of public policies oriented toward a bioeconomy. This research follows a computed analysis based on the R package using Biblioshiny, a web interface for Bibliometrix analysis; this approach offers a positive alternative for studying bioeconomic literature in the traditional bibliometric analysis. This is one of the first research which analyzes the literature pathways of the bioeconomy issue using a computational analysis. Our article concludes that the principles of the bioeconomy have a strong potential to address these related challenges to manage and maintain the environment.

The construction sector has long recognised the decisive role of the various phases of the building lifecycle in the global environment. The identification of the construction environmental impacts is a significant progress for the development of a sustainable supply chain related to the raw material consumption and the construction and demolition waste (C&DW) generation. In this sense, circular economics' principles have solid potential to address these challenges in all European Union countries and especially in France. Nowadays, input-output (I/O) modelling covers the analysis of waste generation (WIO). As the supply chain of the building construction process is complex and has several related activities, and in a preliminary moment a conceptual model was developed, this approach provided an assessment of the mitigation actions of C&DW generation in France. This evaluation shows some positive waste reduction of several materials in the construction process, especially in concrete, metal, rock/rubble and sand/soil. However, the same study exhibits that even materials that can be recycled in the construction process, e.g., concrete, plastic, and metal, might not have a positive waste reduction during demolition due to the lack of proper waste separation and contamination during the process. Reference to this paper should be made as follows: Doussoulin, J.P. and Bittencourt, M. (2018) 'Analysing the circular economy opportunities in the French construction sector related to the sustainable supply chain: a waste input-output analysis', Int.

This article proposes a new definition of the circular economy following analysis and comparison of the most prominent concepts of the biosphere: Sraffa's value theory and Moore's dialectical method. Our paper helps to identify the positions of each of these concepts with regard to free disposal, waste treatment and surplus distribution value. Thus, we are able to show that the mechanisms of the circular economy function simultaneously as part of the appropriation system and as part of the system for the protection of nature. This study enriches the literature on the circular economy by providing analysis of various scenarios of waste disposal. Finally, areas of application and policy implications of the small wins theory are explored in order to guide future research on the circular economy.

Le projet "Empreinte Écologique" appliqué au Parc Naturel Régional de la Haute Vallée de Chevreuse (PNR HVC) porte sur la question des bases d’information, des indicateurs phares et des procédures de concertation d’acteurs pour une gestion durable du capital naturel et des services écologiques à l’échelle territoriale du Parc Naturel Régional de la Haute Vallée de Chevreuse, tout en insistant sur le contexte régional francilien et sur les préoccupations internationales (changement climatique, biodiversité, eau, énergie...).

We are in the middle of the storm and this does not allow us to see clearly what is coming. This often generates partial analyses of the issues of the situation. Therefore, this manuscript attempts to generate an integral perspective on the issues of the crisis. This chapter proposes a discussion of the Coronavirus crisis following analysis and comparison of the most important outstanding conversations of general public health, economics and environmental issues. The objective of this chapter is to travel on the far side of the discussion of the articles presently planned within the academic world and that were analyzed within the bibliometric review, that consist of these three issues. This analysis that integrates these dimensions allows to give an additional prospective answer to the queries exposed by the COVID crisis, conjointly taking into consideration geopolitics as a forgotten dimension within the public discussion. Our paper helps to indicate the positions of every one of those ideas and enrich the literature on the environmental sciences and public health by providing analysis of the consequences of international policies.
