“…The reason behind this, is that numerous advantages could be exploited by the implementation of a holistic circular economic approach. According to recent publications, the European Commission estimated that the EU manufacturing sector alone could potentially have a benefit of 600 billion euros annual economic growth, if a transition to CE was to be achieved [3][4][5]. Finland's annual economy is estimated to experience growth of 2.5 billion euros, while when it comes to the global annual economy, the magnitude of the numbers significantly increases and estimates reach values of 1000 billion US dollars per year [6][7][8].…”

Rising concerns about the impacts that the road engineering industry is imposing to the environment have redirected national road authorities to firmly re-consider the sustainability implications of their operations. Lately, though, sustainability has established a forceful correlation with the Circular Economy and its principles. The road engineering industry, therefore, is moving towards more circular approaches. However, this is occurring without the assessment of the potential impacts of such a transition. For this reason, in this study, a composite indicator, namely, Environmental Sustainability and Circularity indicator (ESCi), for investigating the potential effects that increased circularity could have at the environmental sustainability of asphalt mixtures is developed. It can be utilized as a decision-making support tool from stakeholders involved in both asphalt mixture production and road pavement management. In addition, in this study, four asphalt mixtures with different percentages of Reclaimed Asphalt (RA) were assessed in terms of their “cradle-to-gate” environmental impacts and circularity, by means of Life Cycle Assessment, and Material Circularity Index, respectively. Their fatigue and permanent deformation performances play a key role in the assessment and distinctive results obtained for the asphalt mixtures with increasing RA% and thus, significant environmental benefits and increased circularity are observed after specific RA% thresholds.

“…Therefore, ensuring the availability of good quality aggregates is essential for concrete construction. In addition, the material should be cheap, sustainable, and environmentally-friendly [2,3]. However, in the Netherlands, for example, the availability of river aggregates is decreasing due to high demand, leading to an increased need for alternative sources, such as the use of concrete waste as an aggregate [4].…”

Effect of Recycled Iron Powder as Fine Aggregate on the Mechanical, Durability, and High Temperature Behavior of Mortars

This study evaluates the mechanical, durability, and residual compressive strength (after being exposed to 20, 120, 250, 400 and 600 °C) of mortar that uses recycled iron powder (RIP) as a fine aggregate. Within this context, mechanical strength, shrinkage, durability, and residual strength tests were performed on mortar made with seven different percentages (0%, 5%, 10%, 15%, 20%, 30% and 50%) of replacement of natural sand (NS) by RIP. It was found that the mechanical strength of mortar increased when replaced with up to 30% NS by RIP. In addition, the increase was 30% for compressive, 18% for tensile, and 47% for flexural strength at 28 days, respectively, compared to the reference mortar (mortar made with 100% NS). Shrinkage was observed for the mortar made with 100% NS, while both shrinkage and expansion occurred in the mortar made with RIP, especially for RIP higher than 5%. Furthermore, significantly lower porosity and capillary water absorption were observed for mortar made with up to 30% RIP, compared to that made with 100% NS, which decreased by 36% for porosity and 48% for water absorption. As the temperature increased, the strength decreased for all mixes, and the drop was more pronounced for the temperatures above 250 °C and 50% RIP. This study demonstrates that up to 30% RIP can be utilized as a fine aggregate in mortar due to its better mechanical and durability performances.

“…Finally, in the case of waste, a central issue in CE, the waste hierarchy establishes a priority order from prevention, preparation for reuse, recycling, and energy recovery and disposal [22]. Given the quantity of waste that is produced by the hospitality industry, hotels can develop multiple strategies [4].…”

The circular economy (CE) is considered a possible solution to problems, such as the increasing global demand for resources, climate change and worldwide pollution. CE can help to transform the hospitality industry from its current linear model of production to a circular one. However, there is a lack of research on circular tourism, therefore, this paper’s main purpose is to shed light on CE strategies—reduction, reuse, recycle, redesign, replace and rethink—developed in the tourism sector, as well as the tourism sector’s CE initiatives by means of a business case analysis method. This qualitative multicase analysis allows us to comprehend the CE practices deployed by large hotel chains, thus identifying the CE strategies and best practices. The results show that the main strategies adopted are the reduction, recycle and reuse, in this order. Nevertheless, the remaining strategies have yet to be adopted in the mainstream. This research emphasises the need to promote the CE in the hospitality industry, especially among independent hotels.
