    A new mindset for circular economy strategies: case studies of circularity in the use of water
    (MDPI, 2020) Fernández-Arévalo, T.(Tamara); Viles-Díez, E. (Elisabeth); Tanco-Rainusso, M. (Martín); Kalemkerian, F. (Florencia); Santos-García, J. (Javier)
    In a circular economy (CE) environment, it is important to make good and efficient use of resources and consider that the waste generated in production processes can be a valuable resource. However, the tools and methodologies conventionally used to analyze and evaluate production systems are based on techniques focused on linear production management models, where the primary purpose is to reduce the treatment and management of waste as much as possible and where productive and environmental efficiency are not evaluated simultaneously. Changing the paradigm from a linear to a circular economy requires that a new strategy for production systems be defined, one that makes production processes simultaneously circular and efficient (in terms of quality and productivity). In this context, a holistic vision is needed when implementing CE strategies. Therefore, the main aim of this paper is to provide evidence, through two real case studies in the use of water, that the management of this resource without considering systemic thinking may not be the most circular solution. Main results showed that improvements based on the traditional approach of reducing resource use cannot provide the best results if they are supported only by current process consumption without considering the circularity of resources.

    Hydrogen fuel cell heavy-duty trucks: Review of main research topics.
    (2022) Camacho, M.D. (María de la Nieves); Jurburg, D. (Daniel); Tanco-Rainusso, M. (Martín)
    Road transportation is a significant source of CO2 emissions and energy demand. Conse-quently, initiatives are being promoted to decrease the sector's emissions and comply with the Paris agreement. This article synthesizes the available information about heavy-duty fuel cell trucks as their deployment needs to be considered a complementary solution to decreasing CO2 emissions alongside battery electric vehicles. A thorough evaluation of 95 relevant documents determines that the main research topics in the past ten years converge on public policies, hydrogen supply chain, environmental impact, drivetrain technology, fuel cell, and storage tank applications. The identified research gaps relate to expanding collaboration between institutions and governments in developing joint green macro policies focused on hydrogen heavy-duty trucks, scarce research about hydrogen production energy sources, low interest in documenting hydrogen pilot projects, and minimal involvement of logistic companies, which need to plan their diesel freight's conversion as soon as possible.

    Fresh concrete lateral pressure decay: Kinetics and factorial design to determine significant parameters.
    (2013) Santilli-Almaraz, A. (Adrián); Puente-Urruzmendi, I.(Iñigo); Tanco-Rainusso, M. (Martín)
    The design of vertical formworks is governed by the lateral pressure exerted by fresh concrete; while maximum lateral pressure is the key parameter for formwork design, the rate of pressure decay and the time needed for pressure stabilization is important for determining formwork removal time; the complexity of the problem is due the large number of factors which affect the rate of pressure decay. This works describes an experimental investigation of columns to determine the variation in the initial lateral pressure decay and in the time needed for pressure stabilization with the following variables: coarse aggregate concentration (different sand to total aggregate ratios were used), the use of a plasticizer, the presences of reinforcement and concrete temperature. In the last part of this work a correlation between setting time and maturity functions with the time needed for pressure stabilization was done. The results show that both thixotropic linked to cement grains nucleation and consolidation and cement hydration influences in lateral pressure decay to the point of stabilization. In references with the initial pressure decay, the presence of reinforcement seems to have a major influence. On the other hand the time needed for pressure stabilization could be correlated with the maturity functions.

    Supply chain management in Latin America: current research and future directions.
    (2018) Tanco-Rainusso, M. (Martín); Escuder, M. (Matías); Heckmann, G. (Gerardo); Jurburg, D. (Daniel); Velazquez, J. (Josué)
    Purpose For the past 20 years, Latin American countries have gone from being a low-cost region to significant players in the world economy, with five of its countries ranked among the world's 50th largest by gross domestic product. This paper aims to study the contribution of Latin American researchers in the field of supply chain management (SCM) to aid an understanding of the Latin American impact within global supply chains (SCs). Design/methodology/approach The authors present a study which includes a bibliometric analysis of the papers authored by Latin American researchers in the SCM field and which were exclusively published in journals included in the Journal Citation Reports. In addition, the authors conducted a survey to Latin American researchers and consultants to gain greater understanding of the main difficulties, which in their opinion, have negatively affected the SCM area in Latin America within the past five years, and identify possible misalignment between Latin American research and the challenges for SC in the region. Findings The results show that Latin American research on SCM in the past nine years is not significant for the field considering the number of papers, citations and the papers published in top journals. Another interesting finding is the lack of collaboration among researchers from different Latin American countries, as well as with corporate. Finally, survey results reveal significant differences regarding the main difficulties each country perceived as relevant. Practical implications Comparing results from both analyses, relevant misalignments stand out between published research and the main difficulties detected. These suggest a challenging opportunity for Latin America, emphasizing the need to increase research contribution of the scientific community, through collaboration and alignment toward overcoming the most troublesome difficulties for Latin America. Therefore, the authors suggest future regional research directions which could also help global companies to tackle the challenges faced and optimize performance of their Latin American SCs. Originality/value To the best of the authors' knowledge, no previous research on the quality and impact of Latin American research in SCM has been conducted. Also, misalignments between researchers and practitioners in the region, which allow identifying weaknesses of Latin American SCs, have not been studied before.

    Simulation-Based Process Design and Integration for the Sustainable Retrofit of Chemical Processes.
    (2011) Hernández-Enríquez, A. (Aurora); Tanco-Rainusso, M. (Martín); Kim, J.K. (Jin Kuk)
    This research proposes a novel Retrofit Design Approach based on process simulation and the Response Surface Methodology (RSM). The approach comprises a diagnosis stage to select the, promising variables through a sensitivity analysis, an evaluation stage to assess the impact of the promising variables, and to identify the most important factors through RSM. A reduced model from the process response behavior is built, and an optimization is carried out with the reduced model to identify optimal conditions and performance of the system, subject to objective function and model constraints. All these procedures are simulation-supported. The main advantage of the proposed approach is to handle a large industrial-scale design problem within a reasonable computational effort and to obtain a reduced model based on the most important factors Limitations for the developed method include that the global optimality of the solutions found is not fully guaranteed, while large computational time for simulation may be required when the large number of factors and levels need to be considered, although this is Offset by the reduced optimization time. The proposed Retrofit Design Approach has been applied to the NGL (natural gas liquids) recovery process, in which steady-state process simulation using Aspen Plus TM has been carried out, and complex design interactions existed for retrofit scenarios have been systematically evaluated, leading to optimal strategies for retrofitting through the proposed design method. Both the continuous and discrete design options are considered in the retrofit design, and the results showed that the approach is effective to provide reliable, cost-effective solutions which yield to economic and environmental improvements in the studied processes. The promising sets of retrofit design options were presented as a portfolio of investment opportunities for supporting further decision-making procedures.

    Applying lean techniques to nougat fabrication: a seasonal case study.
    (2013) Tanco-Rainusso, M. (Martín); Santos-García, J. (Javier); Rodríguez, J.L. (José Luís)
    Lean manufacturing has been increasingly applied by leading manufacturing companies throughout the world, led by the major automobile manufacturers and their equipment suppliers. The aim of this case study is to show the applicability of lean manufacturing’s body of knowledge to a different environment: a seasonal food industry. Several techniques and analyses such as value stream mapping (VSM), overall equipment efficiency, spaghetti diagrams, work balance, and discrete event simulation were applied in this case study. Some of the improvement ideas resulting from the tools used were tested in the field to corroborate the findings. Finally, the future state VSM was mapped, where most of the improvement ideas identified throughout the project were consolidated. Whether the path to improvement is marked by increased spending on systems and machinery, human capital, or both, engineers and managers in the frontlines of food production recognize that improvement is a quest and not a destination. Although process industries need a special version of lean manufacturing tools, this case study shows how, with slight modification, several tools can be applied to the seasonal traditional craft industry.

    What motivates employees to participate in continuous improvement activities?
    (2016) Viles-Díez, E. (Elisabeth); Jurburg-Melnik, D.A.(Daniel Andrés); Mateo, R. (Ricardo); Tanco-Rainusso, M. (Martín)
    Continuous improvement (CI) is still one of the strongest ways for companies to achieve process excellence in order to survive in nowadays’ competitive environments. Yet, it is still very difficult to implement and sustain CI systems, mainly because of the difficulty in engaging people in these activities. Based on an exhaustive literature review, followed by a three-round Delphi study with Spanish experts, this paper helps to assess what the main elements are with respect to the CI system that could motivate employees’ intention to participate in CI activities. Main results show 44 elements grouped into 10 factors that could affect employees’ intention to participate. These factors were structured into a more comprehensive model following an interpretive structural modelling approach.

    Continuous improvement leaders, followers and laggards: understanding system sustainability
    (2016) Viles-Díez, E. (Elisabeth); Jurburg-Melnik, D.A.(Daniel Andrés); Mateo, R. (Ricardo); Tanco-Rainusso, M. (Martín)
    Continuous improvement (CI) systems still have room for improvement due to the difficulty in sustaining the system and attaining a high level of employee participation. This study looks to analyse the level of implementation in manufacturing companies of 16 CI routines, and how these routines foster CI and employee participation. Based on a general survey of CI managers from Spain which yielded 147 valid responses, a Cluster Analysis (CA) and a Factorial Analysis were performed in order to group both responses and the variables used into more comprehensive categories. Statistical tests were run to test for significant relationships. This paper introduces a new perspective on the issue of CI maturity levels by using CA to group companies into three categories based on the score of a set of 16 CI enablers, which were in turn reduced to four factors using Factor Analysis, allowing for the identification of improvement challenges depending on the maturity stage of each company. Three different maturity groups of companies were identified, named as Leaders, Followers and Laggards. Results show that companies with better scores on these factors believe to have more sustainable CI systems and a higher level of employee participation.
