“…Changing the mentality of society and engineers will allow treating the waste not only as an environmental issue, but also as an important source of industrial raw materials. Introducing the idea of the closed-loop economy that involves closing the product's life-cycle may result in a reduction in the amount of waste that needs to be deposited in landfills [4][5][6].…”

Abstract:The paper presents the results obtained in the course of a study on the concrete made of aggregate obtained from wastes of sanitary ceramics. Previous examinations proved high in strength and durability of concrete of this type, and it showed a resistance to high temperatures. The material was classified as a fireproof concrete. While searching for the optimal applications of such concrete, a series of examinations and analyses on its thermal energy storage (TES) properties were performed. This paper describes the two-stage experiment on the thermal behavior of the concrete made with sanitary ceramic wastes during cooling processes in comparison to different building materials subjected to the same thermal conditions. On the basis of the thermal, infrared analysis, and suitable calculations, the thermal power and the ability of the composite to store thermal energy was estimated. Finally, it was stated that the concrete made of sanitary ceramic waste aggregate and alumina cement can be recommended as a heat-accumulating material, and in combination with high durability can be used, e.g., for the construction of fireplace bodies.

“…In this way a circular economy could be established, so that the materials loops could be closed, as well as reducing the amount of waste which needs to be landfilled. The main advantage of the use of such an approach in Europe, which is highly dependent on imports of energy and raw materials, lies in the more efficient use of resources, less pollution, and improved economic competitiveness (Blengini et al, 2012;Marie and Quiasrawi, 2012;Knoeri et al, 2011;Turk et al, 2014).…”

“…Numerous studies have reported LCA and LCC of road infrastructure [15][16][17][18]. LCA has been used to quantify the environmental impact due to road construction, operation, maintenance, and rehabilitation activities [19][20][21][22][23][24][25]. Harvey et al have presented a state-of-the-art pavement life-cycle assessment framework on the overall approach, methodology, system boundaries of pavement LCA [26].…”

Multi-Criteria Life Cycle Approach to Develop Weighting of Sustainability Indicators for Pavement

2018

In the past decade, sustainable practices have been adopted in transportation infrastructure projects to reduce adverse environmental effects. To evaluate the sustainability levels of engineering projects holistically, rating systems have been developed to assess and reward points based on various sustainable best practices (indicators). This study aimed to establish a systematic methodology to weight indicators related to materials and resources most commonly used by various transportation infrastructure rating systems based on their contributions to sustainability. A multi-criteria approach for assessing the indicators based on three criteria, indicator performance, environment, and cost, was designed. The criteria were then used to evaluate the indicators and assessed points based on their contributions toward sustainability. Results revealed that state-of-the-art engineering practices could differentiate weighting of points from the typical linear point increase that is traditionally used. In addition, a maximum cap is crucial to ensure that some indicators do not end up being weighted disproportionately.
