These outcomes are frequently shaped by early design decisions. While remanufacturing offers a sustainable alternative by restoring products to like-new condition, its potential is often limited by designs that do not consider remanufacturing from the outset. This research addresses that challenge by introducing a structured Design for Remanufacturing (DfRem) methodology and a CAD-integrated tool to support real-time design decisions. The DfRem framework introduces a new primary design function focused on preserving product functionality across its life cycle. It is supported by a fault tree that identifies failure modes that limit remanufacturing potential and a hierarchy of design principles including Prevent, Minimize, Relocate, Restore, and others. Each principle is linked to actionable design rules that help engineers reduce the need for remanufacturing or improve its efficiency when necessary. To operationalize this framework, we developed CAD plugins for Autodesk Inventor and PTC Creo. These tools use a state machine model to present prioritized design rules based on selected failure modes and user input. By embedding DfRem logic directly into widely used CAD environments, the tool enables engineers to make sustainability-informed decisions without disrupting existing workflows. This approach highlights the critical role of design in enabling circular and resource-efficient product development, making remanufacturing a more practical and accessible strategy during the early stages of product design.</p>\u0000 </div>","PeriodicalId":87290,"journal":{"name":"Journal of advanced manufacturing and processing","volume":"7 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/amp2.70029","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To ensure materials-related sustainability, it is important to enable the use of a greater recycling rate of steel scrap in the manufacturing of new tires. However, impurities like copper compromise the performance of steel wires that are cold-drawn from ~5.5 mm diameter rods. This article investigates copper precipitation in sensitized steel wire rods and their mechanical properties subjected to varying heat treatment procedures. The amount of copper precipitated in sensitized zones as a function of Cu concentration in the steel samples is quantified using scanning electron microscopy. Preliminary findings indicate that an increase in cooling rate during the heat treatment procedure increases the amount of Cu precipitated in the sensitized zones and increases the geometric footprint of the sensitized zones. Tensile tests on heat-treated 5 mm-diameter wire rods showed a higher strain and slightly lower peak stress as the cooling rate decreased. This research thus contributes to a better understanding of the influence of Cu concentration on the microstructure and performance of steel wires used in tire manufacturing, thereby allowing for the enhanced use of scrap steel.</p>\u0000 </div>","PeriodicalId":87290,"journal":{"name":"Journal of advanced manufacturing and processing","volume":"7 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/amp2.70030","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Good demand forecasts are critical for remanufacturers to optimize inventory (of cores, components and finished products) and production planning. Inventory shortages lead to lost sales, delayed fulfillment, or expensive substitutions with new parts, while excess inventory ties up working capital. We collaborated with a large industrial products manufacturer to improve demand forecasting for remanufactured parts requiring periodic replacement. The manufacturer's large global install base of products requires parts replacements at stipulated intervals as part of maintenance. However, the demand tends to be highly variable. We have developed an analytics-based approach to model this variability by considering equipment usage and customer behavior. For installed products, the duty cycles and hence the run-time vary considerably over time. We analyze historical run-time data from products in the field, modeling it as time-series and applying several time-series forecasting techniques to predict future usage more accurately. Additionally, we found that customers do not adhere to the stipulated replacement intervals. To account for such deviation, we characterized individual customer's replacement behavior. By combining each product unit's forecasted run-time with the customer's replacement pattern, we can more accurately predict the upcoming parts replacements. By aggregating forecasts across product units and regions, we generate insights into future demand at headquarters, regional, and dealer levels. Our approach enables manufacturers to optimize inventory across their entire network, streamline production processes, minimize operational costs, and enhance customer service by ensuring timely availability of replacement parts.</p>\u0000 </div>","PeriodicalId":87290,"journal":{"name":"Journal of advanced manufacturing and processing","volume":"7 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/amp2.70028","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the primary reasons for this high scrap rate is insufficient material on the running surface, especially for subtractive recovery.

Besides good successes in recycling PET (No 1) and HDPE (No 2), most of them end up in landfills or waterways and oceans. Even recycling of plastic by mixing them with virgin plastic has problems, as they contain large amounts of pharmaceuticals and other undesirable chemicals. One of the desirable ways to chemically recycle a plastic is to take it back to its starting monomers, which can then be re-polymerized into virgin plastic—a circular recycling. A polyester (PET) polymer can be hydrolyzed back to diacids and diols, and after cleaning, polymerized back to PET with the same characteristics as the original polymer. There are catalytic pyrolytic ways to produce naphtha (C<sub>4</sub>–C<sub>7</sub>) that can be a starting material for ethylene and propylene to be repolymerized to PE and PP. Inductively coupled depolymerization of plastic can, under the right conditions (Eco Fuel Technology, US Patent 9 505 901), take the polymer all the way to its monomer (85–90 + % yield). Mixtures of plastic can be reacted, and the resulting ethylene, propylene, or styrene can be separated to get pure monomers that can be re-polymerized. This will be a true circular chemical recycling and this paper will propose ways to scale up the process to industrial scale.

The WCFF/PP composites were then compounded at 20 wt.% loading of WCFF using a twin-screw extruder. Incorporating WCFF increased the tensile strength to 41.28 MPa and the modulus to 3207 MPa, accounting for 28% and 38% enhancements, respectively. Interestingly, the greatest improvements were associated with the nonsieved WCFF case, and the sieved WCFF fibers provided only marginal enhancements over virgin PP. The outperformance of nonsieved WCFF was attributed to the synergistic reinforcement of hybrid fibers and fines as well as the maintenance of longer fibers in the system. However, the strain at break and impact strength of PP decreased after introducing WCFF. Moreover, the complex viscosity and storage modulus increased with an increase in the filler size, due to the formation of a more effective percolative network. The PP's crystallinity exhibited a relatively strong dependency on the sieving, where WCFF samples with short-aspect-ratio fillers promoted the crystallinity significantly. It was also found that the WCFF degradation onset temperature increased once it was incorporated into PP.
