“…At present, some studies only focus on the alternative methods of resource utilization of these wastes in the resource utilization of WDC, such as the production of building materials, such as bricks (George and Antonis 2021 ; Mojtaba et al 2020 ; Symeonides et al 2019 ; Ayati et al 2019 ; Dai et al 2019 ), concrete (Yang et al 2021 ; Mohsen et al 2021 ; Li et al 2020a , b ; Amelung al. 2020 ; Ma et al 2019 ), aggregates (Bamdad et al 2019 ; Siddique et al 2021 ; Sundis et al 2021 ; Moreno-Maroto et al 2018 ; Prachasaree et al 2020 ), glass materials (Baino and Ferraris 2019 ; Stoch et al 2018 ; Grilo et al 2019 ; Alves et al 2017 ), slag-red mud cementitious materials (Ban et al 2018 ; Faried et al 2021 ; Mymrin et al 2017 ; Ye et al 2017 ), and ceramic materials (Sun et al 2021 ; Cheng et al 2018 ; Ren et al 2019 ; Cao et al 2019 ).…”

“…The obtained vitreous powder is studied by thermal, chemical, and structural characterization techniques. The pellets were pressed and sintered to obtain glass–ceramic materials (Danielle et al 2019 ; Stoch et al 2018 ; Mohajerani et al 2019 ). The research on slag-red mud cementing material mainly uses waste drilling fluid, blast furnace slag, and red mud as raw materials to prepare a new type of cementing material, aiming at achieving an environmentally friendly and efficient solution for waste recycling.…”

Water-based drilling cuttings (WDC) generated during shale gas development will endanger human health and ecological security. The modern analytical techniques are used to analyze the organic pollutants in WDC, and the human health and ecological security risks of harmful pollutants in WDC under specific scenarios are evaluated. The results showed that the content of organic pollutants in WDC was evaluated by human health and safety risk assessment. The comprehensive carcinogenic risks of all exposure pathways of single pollutant benzo(a)anthracene, benzo(a)pyrene, benzo(k)fluoranthene, and indeno(1,2,3-cd)pyrene were acceptable. However, the cumulative carcinogenic risk of exposure to dibenzo(a,h)anthracene particles via skin exposure was not acceptable. It was considered that only dibenzo(a,h)anthracene had carcinogenic effect, and the risk control limit of dibenzo(a,h)anthracene in WDC was 1.8700 mg/kg by calculation. As well as, the “WDC-cement” gel composite structure was deeply analyzed, and the physical and chemical properties and mechanism of organic pollutants in cement solidified WDC were analyzed, which provided theoretical support for the study of WDC pavement cushion formula. Based on the above conclusions and combined with the actual site, by studying and adjusting the formula of WDC pavement cushion, the WDC pavement cushion was finally designed by 6% cement + 50% WDC + 44% crushed stone. The 7d unconfined compressive strength met the requirements of the Chinese standard “ Technical Guidelines for Construction of Highway Roadbases ” (JTG/T F20-2015). Also, the process route of WDC as road cushion product was sampled and analyzed. In addition, the leaching concentration of main pollutants all met the relevant standards of China. Therefore, this study can provide a favorable way for the efficient, safe, and environmentally friendly utilization of WDC, and ensure the ecological environment safety and human health safety of WDC in resource utilization.

To reduce the energy consumed by building part, a new method of producing foam glass at low temperature was proposed in this study. Mineral wool waste and waste glass recycled from building construction and demolition (C&D) process were used as major raw materials. In the meanwhile, calcium carbonate (CaCO3), borax (Na2B4O7•10H2O) and sodium phosphate (Na3PO4•12H2O) were added as extra additives, which played the part of foamer, fluxing agent and foam stabilizer, respectively. The effects of different content of each additives and different sintering temperature on the properties of foam glass were investigated. Bulk density, cross-section view and microstructure of the specimens were showed. The experiment results showed that the optimal content of raw materials and additives was 40 wt.% mineral wool waste, 60 wt.% waste glass, 20 wt.% borax, 1-2 wt.% calcium carbonate and 2 wt.% sodium phosphate, and its optimal sintering temperature was 800℃. The specimen sintered at this optimal condition had the most uniform foam structure and low bulk density of 0.7 g/cm 3. Finally, 2 EnergyPlus TM was used to evaluate the benefit of applying this new foam glass on the reduction on space conditioning loads, especially in relatively colder zones.

“…Similar approaches have been successfully carried out to immobilize hazardous waste from radioactive waste, industrial or hospital waste inside a glass-ceramic structure, using recycled glass to lower down the heat-treatment (sintering) temperature. 26,27 Encapsulation of heavy metals inside a glass-ceramic structure not only is an excellent option to safely immobilize heavy metals, but it contributes further to the circular economy generating high-added value products and avoiding waste landfill disposal. This approach is specially emphasized by EU under "A zero waste program for Europe".…”

Rice husk, an agricultural waste, is abundantly available in many countries such as China, India, Brazil, US, and South East Asia. Despite the massive production of rice husk, it is mainly disposed to landfill. In this work, utilization of rice husk for a potential waste-water treatment is evaluated, along with subsequent encapsulation of the adsorbed heavy metals (Pb and Cd) inside a porous glass-ceramic. Vitrified bottom ash (another source of waste) was mixed with foaming agents in different weight ratios (40:60, 50:50, and 60:40) to prepare a glass matrix for encapsulation of Pb-/ Cd-loaded rice husk. It was shown that using 40 wt% vitrified bottom ash with 60 wt% foaming agents leads to a foam glass with the best pore size distribution. Therefore, this batch was further mixed with 70 volume% (5 wt%) heavy metal-loaded rice husk and was heat-treated at 750°C for 3 hours. The final glass-ceramic porous structure was char acterized using SEM, XRD, compression test, and it was shown that it is safe to be used as it passes the EN12457-2 leaching test.
