“…There is a three-stage change including efficiency, technology, and system changes in industrial sustainability [15]. About society's consumption of natural resources and the impact of industrial activities, operation changes and equipment design for reduced energy consumption are discussed for process-related research, and new developments in process planning and production scheduling are highlighted that consider environmental performance [16,17]. Therefore, how to reduce the impact of the manufacturing process on the environment can be roughly divided into three categories:…”

“…In order to understand the overall energy consumption of the dust collector, the first step is to determine the pressure drop with the suction as P Total from the energy consumption of the motor of the dust collector W motor that is generated by the pressure drop loss of the pipeline and the equipment as P Pipe , P Equip , and P Filter . This can be expressed as Equation (16), where fan efficiency value η Fan is 0.6~0.65, Q is the flow rate of the filter, and P Total is the sum of P Pipe , P Equip , and P Filter . At each T w , the pulse-jet cleaning provides compressed air T p as P clear , flow rate as Q clear , and sequentially cleans the set of filter groups.…”

A growing number of manufacturers are realizing cost and environmental benefits through the sustainability of innovation and optimization processes. Based on polluting less and creating less, the study is pursuing sustainability on increasing operational efficiency by reducing costs and waste. Pulse dust collection systems are commonly used filtration equipment in industries and have lots of energy consumption due to running all day. This study is focused on the optimal parameters for energy saving and cost reduction, and the model is represented by the pressure drop of the filter and the residual powder. The characteristic values of the cleaning efficiency and the air permeability reduction are used for MATLAB to analyze the optimization state. This study found that the material of filter elements, the type of dust, the conditions of pulse-jet, and the filtering speed are the factors that affect the operational efficiency. In terms of cost, the pulse interval time in 10 s is the best parameter, and the pulse time does not affect the overall cost of the filter. Considering energy saving, 0.1 s of the pulse time is the best parameter. In addition, a lower dust concentration is a way to improve efficiency for increasing the filter life and reducing cost.

Making, driving, and disposing of U.S. light-duty vehicles (LDVs) account for 3% of global greenhouse gas emissions related to energy and processing. This study calculates future emissions and global temperature rises attributable to U.S. LDVs. We examine how 2021−2050 U.S. LDV cumulative emissions can be limited to 23.1 Gt CO 2equiv , helping to limit global warming to less than 2 °C. We vary four vehicle life cycle parameters (transport demand, sales share of alternative fuel vehicles, vehicle material recycling rates, and vehicle lifespans) in a dynamic fleet analysis to determine annual LDV sales, scrappage, and fleet compositions. We combine these data with vehicle technology and electricity emission scenarios to calculate annual production, use, and disposal emissions attributable to U.S. LDVs. Only 3% of the 1512 modeled pathways stay within the emission limit. Cumulative emissions are most sensitive to transport demand, and the speed of fleet electrification and electricity decarbonization. Increasing production of battery electric vehicles (BEVs) to 100% of sales by 2040 (at the latest) is necessary, and early retirement of internal combustion engine vehicles is beneficial. Rapid electricity decarbonization minimizes emissions from BEV use and increasingly energy-intensive vehicle production. Deploying high fuel economy vehicles can increase emissions from the production of BEV batteries and lightweight materials. Increased recycling has a small effect on these emissions because over the time period there are few postconsumer batteries and lightweight materials available for recycling. Without aggressive actions, U.S. LDVs will likely exceed the cumulative emissions budget by 2039 and contribute a further 0.02 °C to global warming by 2050, 2.7% of the remaining global 2 °C budget.

“…Remanufacturing, as reviewed by Matsumoto et al [1] and Tolio et al [2], is crucially important for our societies to move toward a circular economy, "which is restorative by design, and which aims to keep products, components and materials at their highest utility and value, at all times" [3]. The concept of circular economy emphasizes the importance of closing material loops via remanufacturing [4]. The potential economic gains from remanufacturing are also substantial.…”

Remanufacturing is a crucial component for our societies to move toward a circular economy. Compared to new manufacturing, the distinctive nature of remanufacturing is found to have high variability, high uncertainty and, thereby, complexity. Therefore, remanufacturers need to be able to adapt to the complexity and to flexibly adjust their processes. Especially, the ability to remanufacturing process planning and control is important. However, few practical methods supporting that are available so far. Therefore, this paper aims to propose a method for designing teams and processes in remanufacturing based on the concept of loosely coupled systems. In the proposed method, Design Structure Matrix (DSM) is applied to identify loosely coupled sub-systems that enable to localize impacts of changes within themselves. These sub-systems are also regarded as cross-functional teams that reduce coordination efforts among line departments and therefore increase the adaptability against uncertainties. As a preliminary validation, the proposed method was applied to a real case of remanufacturing, and then found to be effective for creating teams and processes for remanufacturing process planning and control depending on given uncertainties.
