At this review the interactions between the principles of ecosystem services and the circular economy were investigated in the light of inter-organizational systems. This evaluation was based on more and more complex processes, while the integration of the growing circular economy concept within the shrinking parent ecosystem unveiled challenges and constraints for products’ end of life and quality. It was argued that: (a) The existence of social and people-related barriers can be considered under three groups, namely, the “sustainable provision and modeling schemes”, “socio-cultural appreciation and payment schemes”, and “regulatory and maintenance schemes”, (b) The impacts of circular economy—ecosystem services toward an inter-organizational func...

Particularly, this study examined the: a) current legislation and Directives issued for medical waste management at Greece and among the other EU-members, b) contribution of healthcare wastes (HCW) generation rate on social and economic parameters in selected European countries, c) available procedures, techniques, and methods upon the disposal of infectious wastes at the healthcare studied, and, d) propositions for integrated management of such hazardous wastes. Specifically, the Analytic Hierarchy Process (AHP) methodology was applied under pair wise comparison matrices in two stages: 1) the scale factors and the indicators, and 2) the criteria and their sub–criteria. The assessment of these pair wise matrices included the indicators and the sub–criteria. Subsequently, two pair wise comparison matrices, upon a) the “Fulfillment of environmental objectives” indicator and b) the “Energy consumption” sub criterion, were denoted. The AHP methodology yielded good results; however there is still space of improving the environmental performance. The normalized relative weights obtained for the criteria and sub criteria motivated specific actions that have to be handled. Particularly, the results indicated a very good value in environmental management criteria due the values obtained for the commitment towards the environmental policy standards and the waste management procedures. However, further improvements on staff awareness (such as development programs to enhance sensitivity) and more green purchasing suppliers, should be further addressed.

Regarding them, the aim of this research was to get an update on the current technological advances and the perspectives of its implementation. Thus, a multi-parametric approach has been conducted to analyze the functionality of technologies in wastewater treatment, organic waste management, agrarian development, and food waste in the context of CE. Beside the narrative of the technological view, a critical approach assimilates the environmental, marketing, economic, governmental, and procedural viewpoints and leads to key indicators which are subject to positive and negative externalities. Due to this coexistence , we denoted the complexity of CE principle implementation and the need for specific envisage in each case, while proposing strategies are formulated in the light of social-environmental impact. Finally, further research gaps were proposed for deeper consideration.

Green house buildings and infrastructures have recently attracted the research interest, due to the energy-intensive building sector at all phases of buildings' lifespan: raw materials' extraction, transportation, construction, operation and maintenance, demolition, and decommissioning. The greener orientation of building materials –containing low energy requirements, along with better thermal, physical, mechanical, and waterproof properties– are playing a decisive role in solving various problems of building industry. In this context, the topics covered at this special issue are ranging at: geo-environmental engineering, mining engineering, rock engineering, engineering design upon green building technologies, ecosystems services valuation, circular economy valuation, climatic conditions towards greener buildings, petroleum engineering, off shore and onshore infrastructures, water resources management in building sector, models of atmospheric sciences and climate conditions, in specifying characteristics of building envelopes and orientation. The research perspectives of environmental sustainability, social appreciation, and economics feasibility are also welcome, towards either new buildings, or refurbished and renovated buildings. Under these multifaceted directions, this special issue is published by the International Journal of Earth Sciences and Engineering (IJEE), by selecting technical papers based on peer review that cover all the above key research areas. The quality and technical content of all the papers have to be of high standard and all papers will peer reviewed by subject experts, prior to be selected for publication in the special issue.

In an environmental approach, the ESV refers to the benefits offered to human beings by wetlands, which include provisional services (including timber, food and water), regulating services (including regional climate regulation and flood regulation), supporting services (including soil formation, biodiversity and nutrient cycling), as well as cultural services (including recreational and aesthetic values). In a socio-cultural approach the ESV is increasingly advocated in gaining more attention in the ecosystem service research agenda. In the relevant literature the interrelation between ESV and circular economy has been sparsely addressed, but it is anticipated that the adaptation of ESV to humans' well-being sustains variable ecological, social, and economic values. In parallel, evaluating ESV in monetary units can be proven an effective tool to activate the citizens' responsibility and awareness upon environmental protection, which could further promote the transform from traditional economy calculation systems towards an integrated calculation system of economy-environment In this study, a mechanism upon the relationships among institutional pressure, the relationship with management, sustainable LCA values, and circular economy valuation were examined. It was proven that sustainable LCA management practice is a determining parameter in promoting the improvement of the circular economy capabilities of organizations, while the main deterring parameters with negative moderating effects upon inter-organizational perspectives were also determined.
