ReSpool's engineering and creative teams have innovated proprietary technologies including the Fiber Shredder, which enables textile-to-fiber shredding for high-value applications, and a set of processes for the manufacture of yarns and nonwoven textiles from recycled fibers. ReSpool's circular supply chains begin with discarded clothing collected by Goodwill organizations in the two test regions and involves partnerships with Goodwill to recruit and train workers and install in-house recycling operations. ReSpool then works with textile manufacturers and home goods and apparel retailers on high-value applications through waste-led materials and product development. ReSpool takes a systems-based approach to sustainability research and problem-solving. This article briefly overviews the “systems thinking” framework and demonstrates how core principles of this framework structure the team's objectives, activities, and innovations. Finally, the article contributes to current debates regarding systems thinking and circularity by presenting a rationale for systems-based sustainability research and practice ratcheted to regional systems. By focusing on regional factors, connections, and opportunities, ReSpool aims to maximize its flexibility, relevance, and impact while enabling tailored replication of the model across diverse communities. In this way, ReSpool offers an innovative, circular materials model for the textile and apparel industries, turning textile waste into a source of business innovation, sustainable economic development, and skills training for communities across the country.","PeriodicalId":87290,"journal":{"name":"Journal of advanced manufacturing and processing","volume":"7 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/amp2.70000","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749744","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}

For batch configuration, the limiting current and Sh values were higher than for continuous configuration, indicating that the mixing pattern is influenced by possible flow inhomogeneities during the operation as a continuous mixing stirrer. This could diminish the amount of electroactive reactant that reaches the electrode surface, due to the possible shrinking of recirculation zones during the rotation of the cylindrical stirrer, forming channeling and by-pass flow zones. These results could evidence the existence of slight deviations from the ideal mixer and other non-ideality flow zones associated with the width of curves upon analyzing age function through RTD curves, at the different flow rates employed in continuous configurations.","PeriodicalId":87290,"journal":{"name":"Journal of advanced manufacturing and processing","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/amp2.10186","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143111739","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}

Several studies were performed on the optimization of geometrical and operational parameters. Yet, a full overview about the interactions in between those parameters is still missing, which can be ascribed to the high number of geometrical and operational parameters that can be varied. In the present work, a central composite rotatable design was used to obtain an overview about the interactions in between the geometrical and operational parameters. Through 3D-printing, reactors were printed with high accuracy, assuring exact evaluation of geometrical effects on the flow. With particle image velocimetry the flow was characterized for effective mixing and the corresponding flow regime. The data obtained shows that the established optimization guidelines do not yield optimal operational conditions. Consequently, a new dimensionless number, the so called acceleration ratio <math>\u0000 <mrow>\u0000 <mi>ε</mi>\u0000 </mrow></math>, was introduced to offer additional guidelines for efficient reactor design. Moreover, it was found that the classical oscillatory Reynolds number does not sufficiently characterize the flow regime. An alternative form was derived from the classical Reynolds number and verified by experimental data. Both, the limits of the newly introduced acceleration ratio and redefined oscillatory Reynolds number are in good accordance with CFD-results.","PeriodicalId":87290,"journal":{"name":"Journal of advanced manufacturing and processing","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/amp2.10185","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143118316","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}

This article reports the first four (4) steps of that project. In the first step, the solution for this separation problem was conceptualized. It is a distillation-crystallization-hybrid process. The second step is to validate the concept experimentally from the thermodynamic point of view followed by kinetic considerations. It was found that a 2-stage crystallization is required to purify the main product isomers to the desirable specification that is higher than 99.5 mol%. A heat and material balance model was then constructed for analyzing and optimizing various design variables, also used to understand the operability of the process. Finally, with proper HAZOP analysis and detailed engineering, the pilot unit was designed. Throughout the project, all exercises and efforts are well focused with clear objectives, hence there are minimum detours on the execution; furthermore, the clear objectives enhanced the communications among various disciplines tremendously. It is a valuable asset for senior management in the allocation of resources and budgets.","PeriodicalId":87290,"journal":{"name":"Journal of advanced manufacturing and processing","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/amp2.10184","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143117901","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}

This manuscript describes how the physical and mechanical engineering disciplines help the commercialization of catalysts from evaluation to scale-up and manufacturing. Forming and shaping the catalyst is the first basic step in the catalyst manufacturing industry. Part A shows some of the classic process methods that are employed for this purpose. Catalyst extrudates require proper engineering and process control of their aspect ratio. Catalyst extrudates with a high aspect ratio tend to yield a low reactor fill due to a loose packing. Catalyst extrudates with a low aspect ratio tend to yield high pressure drop. Part B introduces the tensile strength of the catalyst in order to predict the aspect ratio of catalyst extrudates in commercial plants. A force-balance between the tensile strength of the catalyst and the impact forces due to collision experienced during manufacture leads to the dimensionless group <math>\u0000 <mrow>\u0000 <mi>B</mi>\u0000 <mi>e</mi>\u0000 </mrow></math>.

Currently, the most cost-efficient manufacturing solution is the cultivation of cells in perfusion mode. Perfusion allows for high cell densities of up to 200 million viable cells per mL (MVC mL−1) to be achieved, resulting in an increase in yield and volumetric productivity, which is the production of product per unit volume and time. However, culturing in perfusion mode requires large volumes of media, which is a significant expense in process development. Therefore, methods that allow rapid optimization of perfusion media are desirable to decrease operating costs and increase productivity. In this work, a quasi-perfusion methodology using microwell plates (MWP) is used for media optimization to culture CHO-S cells producing IgG1 monoclonal antibodies (mAb) known as trastuzumab, which have clinical applications treating HER2+ breast cancer. Results show blending glucose-rich supplements and sodium butyrate with perfusion-specific base media can lead to an 8-fold increase in monoclonal antibody titre compared with traditional fed-batch media. The original and optimized media were then scaled-up to a custom made, mini bioreactor (MBR) running in perfusion mode. Two-fold higher cell density is achieved in the MBR compared with the MWP, however, when normalizing for cell density, mAb productivity is comparable between the two methodologies. The combined MWP and 250 mL MBR methodology is an optimization tool that enables process development cost savings due to reduced volume of media utilization.","PeriodicalId":87290,"journal":{"name":"Journal of advanced manufacturing and processing","volume":"6 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/amp2.10180","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141371656","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}

Current methods for designing decanter centrifuges rely on simplified models, often leading to inaccuracies. Consequently, manufacturers must perform time-intensive pilot scale experiments to derive their own correction factors. Growing computing power sparks interest in alternative modeling strategies. Grey box models (GBM) combine mechanistic white box models (WBM) and data-driven black box models (BBM), with the optimal structure (parallel or serial) varying by application. For modeling decanter centrifuges, we propose a serial GBM that comprises an artificial neural network that outputs unknown material parameters into a first-principle multi-compartment model. Comparing this approach to alternative data-driven modeling strategies (pure BBM, parallel GBM), we conclude that the serial GBM excels in terms of extrapolation, prediction ability, and transparency while also enabling a better comprehension of the separation process.","PeriodicalId":87290,"journal":{"name":"Journal of advanced manufacturing and processing","volume":"6 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/amp2.10179","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141271979","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}
