“…3). Similar to the previous study (Li et al 2020), GWP was the highest environmental impact index for the boron production from salt-lake brine with 1.25 × 10 3 /1.73 × 10 3 /1.71 × 10 3 /8.37 × 10 5 kg CO 2 eq at acidification/extraction/ reverse extraction/dry stage, while SA was the lowest index with 1.25 × 10 3 /1.73 × 10 3 / 1.71 × 10 3 /8.37 × 10 5 kg at acidification/extraction/reverse extraction/dry stage. GWP and AP for producing 1 ton of boric acid reached 5.52 × 10 3 kg CO 2 eq and 28.0 kg SO 2 eq, respectively.…”

“…This study selected 5 kinds of indicators including acidification potential (AP), global warming potential (GWP), nutrient enrichment (NE), soot and ashes (SA), and photochemical ozone creation potential (POCP) to evaluate the potential environmental impact of boron production from salt-lake brine. The calculation of AP, GWP, NE, SA, and POCP referred to previous report (Li et al 2020). In brief, emission of different target pollutant (CO 2 , CH 4 , SO 2 , NOx, N 2 O, CO, VOC, and PM 10 ) was estimated by sum of emission in different stages.…”

“…The alternative techniques for boron production from salt-lake brine have been investigated although solvent extraction has been widely used for practical production for decades (Cao et al 2018). Nanofiltration has been successfully used for lithium production with relatively low environmental burdens (Li et al 2020) to make it possible for lithium cleaner production. Moreover, nanofiltration technique has also been proposed and recommended for boron production (Cao et al 2018) although the practical production is still in plan.…”

“…Life cycle assessment (LCA) is an emerging and promising method for evaluating the potential environmental impact cause by different processes (Li et al 2020). LCA has been used to determine the life cycle cost and environmental burden of lithium nanofiltration extraction technique (Li et al 2020), the environmental impact of a small multi-effect distillation plant for treating brackish water (Tarpani et al 2019), and process innovation evaluation for manufacturing industry (Vinci et al 2019). LCA provides important information for optimization of production process due to the estimated environmental burden, water/energy consumption, and cost of different stages or production units.…”

No information is currently available on potential environmental impact of boric acid solvent extraction from salt-lake brine although boron production is important for industry, agriculture, and human well-beings. Life cycle assessment (LCA) was firstly used by this study to evaluate the environmental impact of boron production using extraction method with the functional unit of 1-ton boric acid. CO 2 was the pollutant with the highest emission amount among the target pollutants, while both extraction and reverse extraction stages contributed to 61.6% of total emission amount for the boron extraction technique. Global warming potential (GWP) and acidification potential (AP) of producing 1-ton boric acid by extraction technique reached 5.52 × 10 3 kg CO 2 eq and 28.0 kg SO 2 eq, respectively. Extraction/dry stage contributed to the highest/ lowest percentage of environmental impact indices by following the order of extraction > reverse extraction > acidification > dry. Life cycle cost for 1 ton of boric acid was estimated as $1054.83 with 67.5% of internal cost. Approximately 1.59 ton of indirect water and 6010 kWh of electricity were consumed to produce 1 ton of boric acid. The emission amounts of pollutants for nanofiltration boron-production technique were 1.4-1.7 times those for extraction technique. GWP and AP of boron extraction production were comparable with those of the other production processes. The findings of this study will provide the theoretical basis and quantitative data for the sustainable development and cleaner production of boron industry.

Lithium is being recognized as a strategic resource on a global scale, mainly because of its growing importance in the production of lithium‐ion batteries for electric vehicles and energy storage systems. Due to its uneven geographical distribution and limited availability on Earth, extracting lithium from brines and seawater presents a sustainable supply pathway. However, conventional lithium extraction techniques are still challenging, necessitating significant costs and energy consumption. This study primarily employs a solar‐utilizing selective extraction strategy for efficient lithium harvesting by designing a solar‐thermal sandwich sieve structure. Herein, a portable solar‐driven lithium extraction device has been developed based on HKUST‐1 and LIG. Due to the sub‐nano channels provided by HKUST‐1, the hydrated Li+ can selectively pass through the MOF layer. The excellent solar heating of the layer enables the device an accelerate vapor escaping, it then facilitates the delivery of Li+, resulting in lithium accumulation at the interface for convenient collection. The maximum lithium extraction capacity in one cycle is 1467 mg m−2, demonstrating good Li+ selectivity absorption with a high Mg2+/Li+ ratio under 1 solar illumination. Moreover, the device shows excellent cycle stability. This work offers an integrated solar utilization for scalable and sustainable lithium extraction from brine water.

As a key ingredient of batteries for electric vehicles (EVs), lithium plays a significant role in climate change mitigation, but lithium has considerable impacts on water and society across its life cycle. Upstream extraction methods—including open‐pit mining, brine evaporation, and novel direct lithium extraction (DLE)—and downstream processes present different impacts on both the quantity and quality of water resources, leading to water depletion and contamination. Regarding upstream extraction, it is critical for a comprehensive assessment of lithium's life cycle to include cumulative impacts related not only to freshwater, but also mineralized or saline groundwater, also known as brine. Legal frameworks have obscured social and ecological impacts by treating brine as a mineral rather than water in regulation of lithium extraction through brine evaporation. Analysis of cumulative impacts across the lifespan of lithium reveals not only water impacts in conventional open‐pit mining and brine evaporation, but also significant freshwater needs for DLE technologies, as well as burdens on fenceline communities related to wastewater in processing, chemical contaminants in battery manufacturing, water use for cooling in energy storage, and water quality hazards in recycling. Water analysis in lithium life cycle assessments (LCAs) tends to exclude brine and lack hydrosocial context on the environmental justice implications of water use by life cycle stage. New research directions might benefit from taking a more community‐engaged and cradle‐to‐cradle approach to lithium LCAs, including regionalized impact analysis of freshwater use in DLE, as well as wastewater pollution, cooling water, and recycling hazards from downstream processes.This article is categorized under: Human Water > Human Water Human Water > Water Governance Human Water > Water as Imagined and Represented Science of Water > Water and Environmental Change
