“…At the same time, most companies actively pursuing CE practices are phasing out plastics and transitioning to more environmentally friendly materials. In this way, the companies grant that if the packaging cannot be recycled due to strict regulations, contamination will be minimal compared to plastic (Markatos & Pantelakis, 2022).…”

Airlines' negative impacts are rising due to the growth of the industry, and therefore new and more sustainable alternative business models are being developed and implemented. In this context, this paper analyses how airlines are incorporating Circular Economy (CE) into their service model and proposes a framework to identify the main practices of CE that support waste management. After a detailed review of the corporate social responsibility (CSR) reports of a worldwide sample of companies, this paper builds on waste and material management, where airline activities have more impacts on edible and inedible waste. Results show that companies are adopting measures such as recycling in‐cabin waste, incorporating new materials, and defining new systems to make the feeding services more efficient. Nevertheless, CE adoption is still low, and the CE strategies do not seem to follow specific patterns.

“…There are also approaches that combine assessment methods to assess CE. Markatos and Pantelakis [42] introduced a decision support tool that combines life-cycle-based metrics encompassing ecological and economic aspects and a circular economy indicator (CEI) centered on material/component attributes. This CEI is associated with quality characteristics and accommodates the decline in the quality of materials through multiple recycling loops.…”

The circular economy (CE) has recently emerged as a key strategy for promoting sustainability and reducing waste in various industrial sectors. This paper provides an overview of the definition, assessment and enhancement of circularity in general and in five key industries, including aerospace, wind energy, transportation, automotive and sports goods, by using data and information from the literature and for the section of the definitions of the CE also using information from the EC funded project “RECREATE”. The survey reviews in detail the different definitions, assessment methods and metrics used to explore and evaluate circularity, including assessment frameworks such as Life Cycle Assessment (LCA) and assessment indicators. Furthermore, it explores the challenges, possibilities and available tools for enhancing circularity, focusing on digital tools. The survey highlights the importance of a holistic and systemic approach to circularity concerning all stakeholders along the value chain. Overall, this study aims to contribute to a better understanding of the circular economy's definition, assessment, and enhancement and provides insights for future research.

Complex Fuzzy Assessment of Green Flight Activity Investments for Sustainable Aviation Industry

et al. 2022

View full text Add to dashboard Cite

The aviation industry harms the environment mainly via the creation of carbon emissions. Hence, action needs to be taken to ensure the environmental sustainability of the aviation industry such as the recycling of waste products, effective waste management and the introduction of energy efficiency measures. However, at the same time, the implementation of improvements to remediate such problems leads to the creation of additional costs for aviation companies. Companies thus need to conduct comprehensive priority analyses regarding the optimum strategy for the sustainability of the aviation industry. However, there is a very limited number of studies in the literature that focused on which approach should be prioritized. Accordingly, this study aimed at the assessment of the viability of investing in so-called green flight measures in the aviation industry, for which a completely original decision-making model was created. Firstly, the various strategic priorities were weighted and the impact-relation directions between them illustrated aimed at the identification of potential influences by means of a multi stepwise weight assessment ratio analysis (M-SWARA) methodology that incorporates bipolar q-rung orthopair fuzzy sets (q-ROFSs) and golden cut. Secondly, the various flight activities are ranked, and the potential impacts of these activities determined in terms of the strategic priorities of a sustainable aviation industry employing q-ROF as the elimination and choice translating reality (ELECTRE) technique. All the calculations were also computed with intuitionistic fuzzy sets (IFSs) and Pythagorean fuzzy sets (PFSs) aimed at verifying the validity of the findings. The analysis concluded that while energy efficiency comprises the most important factor in terms of strategic priority investment for the circular economy-based aviation industry, emergency response makes up the most crucial activity in the industry. Operational efficiency must be prioritized to decrease the amount of fuel consumed, in connection with which flight routes should be planned according to current weather conditions, which would serve to shorten flight times and, thus, help to increase energy efficiency. Such an approach would make a positive contribution to minimizing carbon emissions aimed at ensuring the sustainability of the aviation industry.
