By leveraging IoT technologies, real-time monitoring and optimization of these parameters can be achieved, minimizing adverse effects and maximizing resource recovery. IoT-based solutions can also reduce operational costs, energy consumption, and environmental impacts through predictive maintenance and process automation. The HMs extracted through BL can be utilized in various industrial sectors, while the residual sludge can be integrated into AD systems for biogas production. The resulting biogas can be used for energy, and the digestate serves as an organic fertilizer, enhancing soil quality.

Agricultural irrigation accounts for the largest share of freshwater demand in all countries where agriculture is practiced. The demand for freshwater in industrial processes follows this trend. Developing alternative water sources, or non-conventional sources, is vital to satisfy the rising demand for freshwater to reduce pressure on natural water resources. Desalination is commonly used to meet the demand for drinking water and high-quality industrial process water. Brine is a by-product of desalination processes that is typically discharged back into the receiving body, where it has a devastating effect on the ecosystem. Instead of disposing brine concentrate as a waste stream, it can be applied for beneficial uses such as irrigation of salt-tolerant plants, algae production, aquaculture, fish farming, and other agro-industrial sectors. The main purpose of this review is to evaluate the applicability and feasibility of circular brine management produced from desalination applications, highlighting innovative approaches to sustainable water management strategies, especially in agriculture irrigation. Furthermore, other industrial sectors that consume significant amounts of freshwater is investigated for their possible applications of waste brine. The findings suggest that repurposing brine can alleviate the pressures on freshwater resources and contribute to sustainable agricultural practices. This review specifically provides a future projection regarding the brine issue, representing a substantial barrier in environmental management in desalination practices. The integration of these strategies can enhance resource efficiency, support irrigated agricultural practices, and promote industrial applications that prioritize water conservation.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 3","pages":"Article 116326"},"PeriodicalIF":7.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143735194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review comprehensively investigated the generation processes and control measures for GHGs emission in CCI process. According to the different ways of primary conversion processes, CCI divided into three major processes, i.e., coal coking, coal gasification, and coal liquefaction. The coking industry accounts for 60 %–70 % of carbon dioxide (CO<sub>2</sub>) emissions in the CCI, with fuel combustion accounting for 80 %–90 % of its largest contribution.

In addition, the adjustment of the H/C in the syngas produced CO<sub>2</sub> in water gas shift unit, and the incomplete combustion of fuel leads to CO<sub>2</sub> emissions from air separation and coal gasification units.
