“…Since these aerogel data come from the main articles, these studies were not included in Table 1. Similarly, some studies examined buildings' annual environmental impacts or aerogelbased materials, especially in thermal insulation LCA articles [50][51][52][53]. Among these articles, those from which aerogel-based data could not be extracted were not included in the Table 1.…”

Over the past decade, aerogel sustainability has emerged as a pivotal area, revealing insights and identifying significant gaps. Exploring the sustainability dynamics of aerogel production, this study utilizes the robust methodology of Life Cycle Assessment to navigate environmental complexities. This study created a road map for sustainable aerogel production by analyzing Life Cycle Assessment studies in the literature. The outcomes of the review acknowledge the diversity in precursors, solvents, and production techniques, highlighting the urgency to bridge these disparities for a sustainable aerogel production path. The majority of studies have examined aerogel production from cradle to laboratory gate. Regarding sustainability, there are gaps in the use and end-of-life phases depending on the application areas for cradle to grave. For this purpose, functional units mutually agreed upon according to their application areas are needed. Moreover, the most significant contributors to environmental impacts are precursors, solvents, and drying techniques. These contributors are compared comprehensively in this review. Findings have emerged that aerogel productions should be examined synergistically to shed light on the debate about which technique is more environmentally friendly, especially for aerogel drying. Finally, sustainability suggestions were made by identifying gaps in the aerogel Life Cycle Assessment with comprehensive hotspots.

“…The life cycle of a building can be divided into five stages: the product stage, construction process stage, use stage, EoL stage and the beyond the life cycle stage [9]. Considering that energy consumption in the use stage accounts for 52% to 82% of the total life cycle energy consumption during a 40-to 50-year life span [10], energy consumption in this stage has always been the focus of research. As a result, there are relatively few studies on the end of the life cycle of buildings.…”

With the promotion of sustainability in the buildings and construction sector, the carbon saving strategies for the end-of-life (EoL) phase have been receiving increasing attention. In this research, life cycle assessment (LCA) theory was employed to study and compare the carbon savings benefits of three different management strategies (i.e., recycling, remanufacturing, and reuse) on the EoL phase of various buildings (including residential, office, commercial, and school buildings). Moreover, the carbon savings potential (CSP) was calculated and analyzed, which is defined as the percentage of the actual carbon savings to the sum of the total embodied carbon of the building. Results show that compared with traditional demolition and landfill treatment, the implementation of integrated management strategies for residential, office, commercial, and school buildings can reduce carbon emissions by 193.5–526.4 kgCO2-e/m2. Among the building materials, steel bar, structural steel, and concrete account for the major proportion of the total carbon savings of buildings (81.5–93.2%). The sequence of the CSPs for the four types of buildings, in descending order, is school, residential, commercial, and office buildings. A building with a life span of 50 years has the greatest CSP. The results of the study can be used to reduce environmental impacts, and have broad positive implications in terms of sustainable construction.

Over the past decade, the increasing emphasis on sustainable material production has brought aerogel technology to the forefront of scientific and industrial research. Aerogels are known for their extraordinary properties, such as high porosity and low density, which make them suitable for a wide range of applications from thermal insulation in buildings to drug delivery systems. This review systematically investigates the sustainability of aerogel production by analyzing the environmental impacts identified in recent life cycle assessments (LCAs). It examines studies on aerogel production using different precursors, solvents, and energy-intensive production methods, especially drying techniques, providing a comprehensive analysis of the environmental footprints and highlighting several hotspots. The review particularly focuses on identifying the disparities in LCA methodologies and the results obtained, which are crucial for crafting a roadmap toward more sustainable aerogel production. The findings emphasize the need for standardized functional units and lifecycle phases that reflect the specific applications of aerogels, thus enabling more accurate comparisons and assessments. The review concludes with a discussion of the critical gaps in current LCA studies of aerogels. It also offers sustainability recommendations based on identified hotspots, advocating for improvements in aerogel production techniques that minimize environmental impacts, enhance material efficiency, and reduce waste. By addressing these gaps, this paper aims to foster a deeper understanding of aerogel sustainability and encourage the development of more environmentally friendly practices in aerogel production and application.
