“…Industrial by-products and waste materials like waste foundry sand [38,39], ground granulated blast furnace slag [40,41], steel slag [42,43], imperial smelting furnace slag [44], copper slag [45,46], bottom ash [47,48], class F type fly ash [48,49], silica fumes [50], palm oil clinker [51], rice husk ash [52,53], bagasse [54,55] and composites [56] have been found to improve buildings' structural and environmental performance when used instead of fine aggregates. Apart from generating industrial by-products, the recycling of C&D waste can also help reduce environmental impact and costs attributable to building materials [57]:…”

Achieving sustainable buildings is a challenging task. Building sustainability involves "green building" design and construction, taking account of both environmental elements and economic benefits, along with social obligations to the society we live in. This article aims to critically review and analyse studies of the building and construction industry that deal with aspects of sustainability, including environmental life cycle assessment, life cycle costing, social life cycle assessment and cleaner production strategies, and to examine the research gaps in order to generate recommendations for further research. About 807 refereed research articles on residential buildings published over the last 10 years (2009-2019), were downloaded, having been searched from online databases (including Scopus, Web of Science, ScienceDirect and Compendex) using keywords. Building materials, embodied energy and operating energy were found to contribute chiefly to the environmental and socioeconomic objectives of the construction industry. Many studies covered only the life cycle tools (such as environmental life cycle assessment, life cycle costing, and social lifecycle assessment) used in the sustainability assessment process. The "carbon footprint" concept is the most commonly used indicator in building sustainability assessments, underlining the urgent need to deploy more diverse environmental impact categories in order to avoid trade-offs among environmental, social and economic objectives. The social life cycle assessment tool needs a methodological breakthrough to improve its application in the building industry. In most of the studies, only an approximate evaluation of buildings' service life is the main consideration in life cycle assessments, while the important factor of the quality of the materials used in buildings is often neglected. However, a methodological approach to estimate the service life of structures that considers the durability of different building components would provide a more realistic life cycle assessment. Hence it would be judicious to address the thematic and methodological gaps identified in this paper, thereby optimising the understanding and communication of life cycle outcomes in building sustainability.

“…Nowadays, it is still a challenge to use glass wastes in construction sector. Therefore, in many papers, researchers have considered the possibility of recycling cullet derived from glass packaging, cathode-ray tubes, windows, or windscreens [1][2][3][4][5][6][7]. It has been proposed to use for cement production as small aggregate, pozzolanic additive or chemical admixture [8][9][10][11][12][13].…”

Adsorption of eriochrome black T (EBT) and rose bengal (RB) mixture from aqueous solutions was investigated using a mixture of low-cost biosorbents – 50 % of raw state potato peels and 50 % of raw state eggshell (M 50%). The surface charge distribution was determined by acid-base titration and the point of zero charge of the M 50% was found to be 8.5. The adsorbent materials were characterized by Fourier transform infrared spectroscopy and X-ray diffraction. It was confirmed that M 50% was mainly composed of calcite and cellulose. The effect of various operating parameters such as contact time, pH, temperature, etc., was studied. The amount of the adsorption decreased when solution pH increased. The pseudo-second order kinetic model provided the best fit to the experimental data for the adsorption of EBT and RB. The obtained thermodynamic parameters indicate that the adsorption process is endothermic one. According to the obtained results, the new biosorbent may be recommended as an industrial adsorbent for the treatment of effluents containing EBT and RB.

“…Glass, as noted by Gómez-Soberón et al [4], is a different type of recyclable material available in great quantities to supply the demand for substitute construction materials. Glass itself is also a solid residue with several environmental impacts: it is non-biodegradable so it permanently occupies landfills and associated pollution can be pervasive in the air, water and soil [2], [4]. A possible solution would be the use of glass in concrete and mortar mixtures since it has chemical composition and phases similar to traditional supplementary cementitious materials (SCMs) [5].…”

The necessity to reduce the consumption of cement in cementitious composites is a worldwide concern and the partial replacement of cement with industrial waste has gathered considerable interest. One type of industrial waste is glass, which is rich in amorphous silica but can present problems with its use due to the alkali-silica reaction (ASR). The objective of this study was to analyze the compressive strengths of mortars using ground glass residue (GLR). Milling times of 16 h and 32 h were conducted and GLR tested in cement substitutions of 10 w.t.%, 15 w.t.% and 20 w.t.%. A statistical analysis was performed to verify which factors affected mortar strength. The mitigating effect of GLR in ASR was also tested. Results showed that milling time did not affect resistance significantly but w.t.% substitution did. The substitution of 20 w.t.% proved to provide the best result as it was statistically equal to the standard mixture.
