Apart from benefiting the environment and ecosystem, the remanufacturing strategy has positively affected socioeconomies of various countries (Wahab et al., 2018). Being one of the EoL recovery strategies, remanufacturing is widely implemented in the transportation industry, namely aircraft, automotive, rail, and marine sectors. To date, the world's largest sector that benefits from remanufacturing is the automobile parts industry. In the aerospace/aircraft industry, original equipment manufacturers are involved in the remanufacturing process to a very great degree. It is known that many assemblies and structures such as engines, avionics, landing gear, and cabin interiors undergo remanufacturing procedures at least once. It is reported that some high-performance products such as Caterpillar's heavy-duty engines can be remanufactured as many as six times and serve seven use cycles. In the marine industry, intensity of remanufacturing is low compared to other transportation sectors such as aerospace, automotive, and rail. For example, marine components such as engines, propeller shafts, compressors, and pumps have been successfully remanufactured in many countries, but remanufacturing of large structures such as hull and vessels has not been reported thus far. Today, with a large number of ships approaching EoL, the share of remanufacturing should be increasing due to its positive impact on the environment (Wahab et al., 2018).
Demystifying the Industrial IoT Paradigm

Business situations in normal manufacturing versus remanufacturing units are different, while the former are less dynamic but larger in size, the IoT can help with process planning in both types of industries. While remanufacturing helps saves raw material by reusing available material, reducing energy consumption, and minimizing equipment costs, the challenges are in a more complex process planning with fixed suppliers and markets. The IoT historic data can help simulate process planning by improving data acquisition, capturing more accurate data, avoiding human omission, and hence improve data validity. Process controls can be achieved by having data interpreted and validated by subject matter experts locally or remotely, and actionable items so derived to be presented to plant personnel at the right time. With sensor technology advancements including self-powered, self-calibrated, error detecting and correcting, and nonintrusive capabilities production process can send information from hundreds of sensors to monitoring systems including asset management or enterprise resource planning systems through the IoT gateways. Examples can be a propulsion jet motor sending information on temperature and speeds to ground staff, or a liquid packaging slitter plant sending video footage of defects in printing and ink coloration.

Increasing global environmental awareness, evidenced by recent worldwide calls for control of climate change and greenhouse emissions, has placed significant thrust on green technologies which are both eco-friendly as well as economical. Remanufacturing is one of the unquestionable green technologies, which reduces toxic emissions in the process of excavation of raw materials to manufacturing of final product whereas recycling could also reduce the carbon footprint contribution from mining process (Figure 15.15). Repairing and remanufacture tooling presents large reductions of 85%–90% of energy consumption, environmental emissions, and manufacturing costs of commercial and military components (Liu and Yao 2005; Morrow et al. 2007; Serres et al. 2011; Xiong et al. 2008).
Can carbon asset pledge financing be beneficial for carbon emission-dependent engineering machinery remanufacturing?

As a sustainable production mode, remanufacturing takes into account both economic benefits and low-carbon development, which has been highly concern by enterprises in practice, especially in the engineering machinery industry (Yi et al. 2016a; Hong et al. 2022; Kushwaha et al. 2022). For instance, Sany Group, the leader in the engineering machinery industry in China, has been layout remanufacturing since 2011. Studies reported that the remanufacturing strategies not only save costs but also largely reduce unit carbon emissions compared with general the manufacturing strategy (Örsdemir, Kemahlıoğlu-Ziya, and Parlaktürk 2014). More and more enterprises have recognized and implemented remanufacturing activities in recent years, such as Xu Gong Group, Zoomlion Heavy Industry Co. Ltd, and Weichai Power Co.Ltd.
Coordination mechanism for a remanufacturing supply chain based on consumer green preferences

The rapid development of industry enriches our lives but also creates considerable electronic waste, which leads to serious environmental pollution. In recent years, the concepts of sustainable development, green development and resource recycling have gradually become popular. With improved living standards and increased environmental awareness, consumers pay increasing attention to the green degree of products, such as unit energy consumption and unit carbon emissions. Thus, supply chain management is gradually becoming increasingly green. Governments have formulated and introduced relevant regulations and laws to guide green strategy development in the supply chain. Because remanufacturing can substantially save energy and raw materials and reduce pollutant emissions, it is a new way to balance economic and environmental benefits that is increasingly accepted by firms (Zhao, Zhu, and Cui 2018). Increasing numbers of firms have become aware that remanufacturing waste products can not only result in profits but also improve corporate reputation and the ecological environment. Extended producer responsibility (EPR) is a concept that emphasises the responsibility that the producer should bear in not only the production process but also the entire product life cycle, especially in terms of recycling and disposal after abandonment. Only when members of the remanufacturing supply chain cooperate with each other can they better implement remanufacturing and improve their own competitiveness and profits. Therefore, many firms are urgently attempting to establish coordination mechanisms for the remanufacturing supply chain.
An integrated system with multiple product lifecycles for remanufacturing (IS-MPLR): new opportunities and challenges

The remanufacturable core (or called key component) is the bridge that connects multiple products and forms multiple life cycles. By using the core as the main material source instead of consuming virgin materials and conserving their physical form during reprocessing, remanufacturing obtains the remaining value of cores from materials, energy, and labor (Wei, Tang, and Sundin 2015). As a result, remanufacturing can bring both economic and environmental benefits, which has attracted the attention both of industry and academia. In recent years, several reviews on remanufacturing have been published. The extant literature on remanufacturing mainly be divided into three levels, that is, the strategic level (including reverse logistics and closed-loop supply chain research), the tactical level (including product management, market structure, and channel competition), and the operational level (including remanufacturing design, production process, aftermarket/recycling, disassembly, and technology). Table 1 shows the specific research content of these reviews in detail.
