Measuring Circularity: Tools for monitoring a smooth transition to Circular Economy

Sustainable Chemistry and Pharmacy

Therefore, the implementation of the Circular Economy model is prioritized by policymakers and the research community. The European Union is in accord with the smooth transition towards a Circular Economy through the Circular Economy Strategy, The European Green Deal (carbon neutrality by 2050) as well as the Sustainable Development Goals (SDGs) of the United Nations. Replacing the conventional business models with circular business models entails a change in technological aspects involving the R strategies (refuse, reduce, recycle, etc.). For a beneficial transition, Circular Economy should be monitored to give out quantitative measurable data. Quantifying Circular Economy can be achieved through the use of Key Performance Indicators, Life Cycle Analysis, Material Flow Analysis as well as the use and development of quality protocols (ISO/TC 323). Such tools will aid with measuring Circular Economy performance (urban or industrial), support decision-making (policymakers, CEOs, etc.) and highlight strengths, weaknesses, blind spots and opportunities regarding circularity. This research analyses the use of monitoring of three main monitoring tools in the framework of Circular Economy using SWOT analysis (Strengths, Weaknesses, Opportunities, Threats) to provide a collective understanding on the implementation of Circular Economy in different settings (urban, industrial, domestic) and provide a clearer pathway towards this transition. The three tools analysed were Key Performance Indicators, quality protocols and digitalization while a hybrid approach was proposed to tackle the shortcomings and utilize the strengths of each of the three methods. The results of the study are expected to provide context to policy makers, academics, the industry, economists and other key players into the synergies necessary for circular economy implementation as well as the necessity of data collection and continuous monitoring for a smooth transition towards circularity.

The city of tomorrow: Challenges and Solutions. A case study of a coastal town

One of the most important anthropogenic factors affecting ecosystems and sustainability is the rapid growth of cities in both size and complexity. According to United Nations as at mid-2017, the global population was an estimated 7.6 billion people, and it is expected to reach 9.8 billion (2050). As the world urbanizes, the role of cities in defining sustainability outcomes increases in importance. Even though cities expansion contributes to economic prosperity and social growth, at the same time, it poses severe challenges both to the environment and social system. The changing from “unsustainable cities” to “sustainable, green and smart cities”, has become a major topic in research community and policy making for endorsing urban sustainability. As a result, the United Nation Sustainable Development Goals were developed as an ambitious blueprint for achieving peace and prosperity while also protecting the environment. Especially SDG 11 is dealing with making cities inclusive, safe, resilient and sustainable. Moreover, Circular Economy is receiving increasing attention globally as a way to overcome the current production and consumption model based on continuous growth and increasing resources input, with aim to increase the efficiency of resource use in order to achieve balance and harmony between economy, environment and society. The objective of this paper was to identified the major challenges occurred due to the rapid urbanization in a coastal area giving emphasis to Particulate Matters Emissions PM2.5, and how the use of the PM2.5 emission index could be used as an indicator for determining the urban metabolism of an island area taking into account that the increase in the concentration of PM in an area is directly related to the increase of anthropogenic activities resulting from population growth and consequently the increase in flows of materials and services and at the same time the increase in the production of solid and liquid waste and gaseous emissions. The higher the index, the greater the degree of metabolism of an area and the impact on air quality.

Shaping Sustainable Cities: A Long-Term GIS-Emanated Spatial Analysis of Settlement Growth and Planning in a Coastal Mediterranean European City

In order to address such issues, assessing the current situation of European metropolises is crucial to understanding new urban development models. In light of these dynamics, our study focused on urban expansion in Pafos, Cyprus, between 1993 and 2021. Such dynamics were examined through photointerpretation (using kernel density estimation) via the ArcGISPro spatial analyst tool. The empirical results of this analysis are considered particularly insightful, especially those regarding urban sprawl and its implications for future land management for the study area, and could help toward shaping specific policies to guide cities towards sustainable and environmentally friendly development. The analysis reveals a gradual increase in settlements ove...
