“…It is worth pointing out that the Ba–Ca–Fe oxides can work at temperatures below 400 °C, much lower than those for the reference OSMs. Such low operating temperatures, particularly the lowest value of 370 °C of Ba 5 CaFe 4 O 12 , are advantageous for potential materials used in the energy-saving CLAS desterilizing waste heat. , …”

“…High-performance OSMs operating at 200–400 °C, suitable for energy-saving CLAS, have not yet been developed. These temperatures are within the range of waste heat from steel plants, which possess the most waste heat potential among industries. , Perovskite-type Sr 0.76 Ca 0.24 FeO 3−δ with an oxygen/vacancy-disordered structure is a cost-competitive OSM with an OSC of 2% with respect to the total weight although its operating temperature is relatively high (550 °C) . Ca 2 AlMnO 5+δ is also a rare-metal-free OSM, advantageous for O-PSA for large-scale plants, while extracting absorbed oxygen from this material requires temperatures as high as 550 °C .…”

We present the discovery of Ba 5 CaFe 4 O 12 , a new ironbased oxide with remarkable properties as a low-temperature driven oxygen storage material (OSM). OSMs, which exhibit selective and rapid oxygen intake and release capabilities, have attracted considerable attention in chemical looping technologies. Specifically, chemical looping air separation (CLAS) has the potential to revolutionize oxygen production as it is one of the most crucial industrial gases. However, the challenge lies in utilizing OSMs for energy-efficient CLAS at lower temperatures. Ba 5 CaFe 4 O 12 , a cost-competitive material, possesses an unprecedented 5-fold perovskite-type A 5 B 5 O 15−δ structure, where both Fe and Ca occupy the B sites. This distinctive structure enables excellent oxygen intake/release properties below 400 °C. This oxide demonstrates the theoretical daily oxygen production rate of 2.41 m O2 3 kg OSM −1 at 370 °C, surpassing the performance of the previously reported material, Sr 0.76 Ca 0.24 FeO 3−δ (0.81 m O2 3 kg OSM −1 at 550 °C). This discovery holds great potential for reducing costs and enhancing the energy efficiency in CLAS.

“…There are five steps in the remanufacturing and recycling steps that can be compared with recycling, as shown in Table 4, where the length of embodied value conserved was calculated by multiplying the length of the WSS by the ER. (1) Alligator shearing: the same quantity of WSS can be recovered while the WSS is lost by shredding, while it is recovered by CNC cutting; (2) no embodied value of WSS is obtained by sorting.…”

As a better alternative to the energy‐intensive process of recycling waste sheet steel (WSS) from the exterior components of end‐of‐life vehicles to produce new steel, the feasibility of remanufacturing WSS into angle mesh steel (AMS) for construction applications is evaluated. A remanufacturing unit with a capacity of 1278 m2/day of WSS (30,000 vehicle/year) was evaluated using a triple‐bottom‐line sustainability analysis of the technological, economic, and environmental feasibilities by hybrid defuzzification–curve‐fitting, solid‐waste recoverability management, and weighting methods. Based on the remanufacturing productivity, an economic feasibility index was calculated considering the sales potential and profit, while the energy and CO2 emission savings were used to evaluate the environmental feasibility. The technical feasibility considered machine parameters and topological properties of the WSS. The Volkswagen Passat has the best remanufacturability of 200 analysed vehicle models. Remanufacturability indexes of 0.61 and 0.86 were calculated, giving remanufacturing efficiencies of 58%–82%. All feasibility indexes exceed literature thresholds, indicating that the proposed remanufacturing process is a sustainable business strategy and contributes to the United Nations Sustainability Goals of climate action; responsible consumption and production; no poverty; and industry, innovation, and infrastructure.
