The Circularity of MSW in Urban Landscapes: An Evaluation Method for a Sustainable System Implementation
2022
The debate on the sustainable perspective of a circular economy and MSW (Municipal Solid Waste) management is no longer focused on the resolution of an emergency and on the pure technicality of creating efficient services. New light has been shed on the operational phase, as often unresolvable technical-environmental issues during service management lead to a state of decay, affecting urban vulnerability and users’ involvement. The research aims to develop an auxiliary tool for public administrations in planning a zero-waste future whilst enhancing the urban landscape. This study considers the perspective of virtuous management of the resource flow cycle along with evaluating implementable …
Safety diagnostic method in urban circular intersections
2004
The available knowledge of traffic safety at roundabouts is not a complete reference for geometric design; where there are organizational schemes for junctions characterized by a geometric design, quite different driving behaviours are required from those that are observable at roundabouts. This is very frequent in urban areas, where the existing constraints, particularly physical ones, often render it necessary to make “compromise choices” relating to one or more geometric features of the roundabout (central island shape, circulatory roadway width, symmetry and number of the arms, entry width, etc). The objective of this study is to explain the accident phenomenology of this kind of road s…

Designing Dynamic Sustainable Business Models to Assess the Feasibility of an Industrial Symbiosis: The Case of the Retro-Port Area of Trieste
2023
This study evaluates the managerial sustainability of implementing a decision support system for industrial symbiosis through a recent business modeling methodology. The decision support system is intended to facilitate the identification of implementable industrial symbiosis good practices in a pilot project located in the industrial retro-port area of Trieste. To evaluate the feasibility of this project, a qualitative “Dynamic business model canvas for sustainability” was designed and supported by a system dynamics approach using causal loop diagrams. The study analyzed various governance scenarios for managing the decision support system (public, private, or public–private partnership) a…
Анализ проблем развития лесопромышленного комплекса при формировании модели экономики замкнутого цикла на примере Томской области
2019
The main objective of the paper is the conduction of the timber industry complex problems analysis from the circular economy and sustainable development point of view. The problem of waste is considered in conjunction with other environmental, economic and social problems. A modeling of the value chain process and the formation of threats along the whole chain «nature (forest) – economy – society (consumer)» is being conducted. A classification of the development problems in the timber industry complex on the basis of «created values» and «production factors» has been developed. Planned growth in logging volume and wood processing, expansion of unused waste require the development of a spec…
Institutional arrangements for sustainable development: Cases from the Navarra Province (Spain).
2015
After more than 20 years of the Earth Summit, Sustainable development is still recognized as one of the main challenges of the XXIst century. World leaders are putting new emphasis on the need to resolve urgent environmental challenges underlining their link with the wellbeing of humankind and the very conditions that made life possible on the planet. We are immersed in complex socio-ecological systems where sectoral or simplified responses are not adequate. A more systemic vision is imperative to effectively address the challenges faced. New approaches are being developed to integrate social, environmental and economic concerns in all human activities. Particular attention is given to deco…
Basic assumptions for introducing circular solutions in the buildings sector
2016
Tradycyjne, linearne modele biznesowe są jedną z głównych przyczyn braku zrównoważonego rozwoju, nadmiernego wykorzystywania zasobów nieodnawialnych i energii, a także nadmiernego wytwarzania odpadów. Odpowiedź na te problemy stanowi koncepcja gospodarki o obiegu zamkniętym, której celem jest poprawa wydajności w gospodarowaniu zasobami i energią w każdej fazie cyklu życia produktu (usługi). Głównym celem niniejszego artykułu jest określenie, co może być uznawane w sektorze budownictwa za produkt w ramach gospodarki o obiegu zamkniętym, a także, jakie rodzaje takich produktów i / lub usług mogłyby być potencjalnie wykorzystane przez firmy doradcze funkcjonujące między innymi w sektorze budo…
Preliminary Evaluation of Plasmix Compound from Plastics Packaging Waste for Reuse in Bituminous Pavements
2021
Finding an appropriate technical solution for reusing waste plastics is crucial for creating a circular plastic economy. Although mechanical recycling is the best option for recycling post-consumer plastics, some heterogeneous mixed plastics cannot be recycled to produce secondary material due to their very low properties. In this case, alternative routes should be considered in order to limit their disposal as much as possible. Therefore, in order to solve the environmental problems in the landfills of plastic waste recycling, and to improve the mechanical performance of bitumen for road pavement, the reuse of these post-consumer plastic wastes are preliminarily evaluated for the modificat…
