“…Even remanufactured quantity is low but if the unit price of remanufactured is high, this will which show high economic effect. Economic and environmental effects of revitalization based remanufacturing can expand remanufacturing market (Jun et al, 2020). Contents based analysis and comparative literature based analysis economical effect is the difference in price between used and remanufactured equipment.…”

Aims: Accelerated developments of CNC machines will let huge amount of milling machines to be out of date. To cope with such problem conventional milling machines can be upgrading by using what is called emerged technology which is of attributes of: The same performance of new machines can be obtained in like-new form remanufactured CNC milling machine. Economic feasibility can be certain. Various purposes can be satisfied include education, training and industry. Efficiency and accuracy requirements can be within limits of customer expectations. Sustainability assessment approach that contains feasibilities of technology, economic and environment modeling for conventional milling into CNC machine tool remanufacturing. Study Design: Literature is surveyed for specifying criteria of feasibilities of technology, economic and environment modeling. Mathematical sub-models are confirmed based on comparative literature based analysis to be used to find the values of indexes of assessment feasibilities within insights of experience based analysis. Feasibilities which are selected to conduct sustainability assessment of remanufacturing processes include sub-feasibility of:- Easy of disassembly sub-feasibility: As low as the time of disassembly, the higher the index of criterion and the easier disassembly. Sub-feasibility of cleaning: As easy as the cleaning process, the lower the index value of criterion. Sub-feasibility of inspection and sorting: As low as the time of inspection and sorting, the higher the index of criterion and the easier inspection and sorting. Sub-feasibility of upgradability: As high as the accuracy of remanufactured milling into CNC machine tool, the higher the index value of criterion. Easy of reassembly sub-feasibility: As low as the time of reassembly, the higher the index value of criterion and the easier reassembly. Sub-feasibility of tack-back cost: It is net price of conventional milling machine to be remanufactured into CNC machine tool. Sub-feasibility of remanufacturing process cost of: It is expense of purchasing replacing parts, material resource consumption and electrical energy consumption. Sub-feasibility of overhead cost: Operating expense to keep continues machine tool remanufacturing business. Material saving sub-feasibility: It is the mass of reused components. Energy saving sub-feasibility: It is the ratio of consumed energy to embodied energy as a result of preventing manufacturing processes by remanufacturing. Pollution reduction sub-feasibility: It is embodied emissions reduction as a result of preventing manufacturing processes by remanufacturing. Place and Duration of Study: Middle Technical University, Institute of Technology-Baghdad, Mechanical Techniques Department, between February 2020 and July 2020. Methodology: Study methodology includes the following outlines:- Literature survey. Comparative literature based assessment application. Experience based analysis application. Isolation of indices Weighting of indexes Sustainability Index calculation Results: Comparative literature based analysis and experience based analysis are used to find the indexes of sub-feasibilities where assessment feasibilities can be calculated through multiplication of index weight by weight of importance. Three evaluation results are calculated to assess the performance of sustainability where index value of (70%) can refer to that conventional milling machine is of high innovative contribution potentials to deliver sustainable solution of CNC machine tool remanufacturing. Conclusion: Technology, Economic and environment are of good evaluation indexes and conventional milling into CNC machine tool remanufacturing is directed toward sustainability.

“…Jun et al [17] conducted an LCA and estimated the environmental impact of the manufacturing process by multiplying the weight and material of each part of a hydraulic cylinder and reducer (=device) used in a construction machine and the replacement rate of the part by the characterization factor for the material. Additionally, previous studies have estimated the environmental impact of a construction machine by multiplying its estimated weight with the characterization factor of the material [17,18]. A study was conducted on the LCA of new construction and mining machines.…”

In this study, we assessed the environmental impact of the remanufacturing of mining machinery components, by analyzing commonly used parts in a machine setup. No previous studies have conducted a detailed environmental impact assessment of any manufacturing processes for new or remanufactured components used in mining machinery. We analyzed the system boundaries and conducted inventory analysis to understand their function and determine their unit role in the machine. Then, we evaluated the environmental impacts of the manufacturing processes for the subparts and assy parts, along with the impact of logistic and remanufacturing processes. In particular, we assessed hydraulic equipment, which is a common component of mining machinery, and conducted a comparative assessment of the environmental impacts of new and remanufactured components. Our results indicated that the global warming potential (GWP) per mining machine throughout its lifecycle (LC) could be reduced by ~194 ton-CO₂eq./LC. Assuming that the number of mining machinery in operation at a global scale is 571 machines (or units) per year, the GWP would be reduced by ~110,000 ton-CO2eq./year.
