Natural stoppers are a magnificent closure for the production of aging wines and unique wines, whose application is limited by the availability of raw materials and more specifically of cork sheets of different thickness and quality. The growing demand for quality wine bottle closures leads to the search for alternative stopper production. The two-piece stopper is an alternative since it uses non-usable plates in a conventional way for the production of quality caps. The present study has analyzed the impact of the manufacture of these two-piece stoppers using different methodologies and for different dimensions by developing an LCA (Life Cycle Assessment), concluding that the process phases of the plate, its boiling, and its stabilization, are the phases with the greatest impact. Likewise, it is detected that the impacts in all phases are relatively similar (for one kg of net cork produced), although the volumetric difference between these stoppers represents a significant difference in impacts for each unit produced.

The current electrification status in West African countries presents rural electrification rates below 40%, national grid losses above 39% with frequent disruptions, and electricity prices averaging $0.35/kWh, up to national values of $0.66/kWh. With this, off-grid systems have gained great attention during the last decade as energy solutions; especially solar home systems (SHS) and mini grids. Nowadays, 385 mini grids with a power of near 30 MW are operating in West Africa, with 95% based on PV. Since 2019, result-based tenders with international aid funding—more effective than previous competitive tenders—seek to install at least 317 new mini grids in Togo, 250 in Nigeria, 100 in Burkina Faso, and two in Mali. Besides, the market for mini-grid energy access start-ups grew from $19 million in 2013 to $339 million in 2018. Despite this recent development in West Africa, research and data for mini grids in this region is scarce, and it is mostly approached from the technological side, with a striking lack of information regarding the social impact. This work tries to describe the present status of research and current operating installations, as well as the main challenges for future development of off grid mini grids in West Africa, which pose as the missing link between SHS and grid extension.

This research proposes a new index to evaluate the stability of the melting process, in three-phase electric arc furnaces (EAFs), based on the acoustic signals generated during the different stages of the casting. The proposed stability index is obtained by characterizing the time and frequency domain of the acoustic signals. During EAF monitoring, acoustic signals were acquired using a microphone coupled to an NI USB-9234 acquisition system. To validate the results, the voltage and current signals were measured with the aid of a Circutor AR6 power analyzer for three-phase electrical networks. The results showed that the acoustic signal energy in the frequency range of 1 to 12 kHz can be used as an indicator of the process stability in the EAF. Finally, the validity of the proposed stability index is evaluated from the process characterization using the harmonic distortion analysis methods and the dynamic U-I characteristics of the arc voltage and current signals. The results obtained demonstrated the effectiveness of the proposal and constitute a starting point for advances in the automatic control of the process in the EAF, from the acoustic signals.

In recent years, consumers of red wines have demanded aged wines with intense color and a well-integrated fine wood bouquet. Traditionally, wines with these characteristics have been obtained from aging in oak barrels. This type of vinification incurs high costs, including costs associated with the acquisition and use of oak barrels. After five or six vinifications, these barrels are no longer capable of providing an adequate contribution of wood compounds to the wine, because of the exhaustion of their transfer capacity. An alternative to extend the life of these barrels is the introduction of toasted oak staves inside the barrel. In this study, a comparative analysis of the aging of a red wine in new and renewed barrels was developed by inserting toasted staves and analyzing the wine in its different stages, as well as its physical, chemical, and colorimetric characteristics. This study confirms that the use of insert staves anchored in exhausted barrels helps to prolong the useful life of barrels, while maintaining quality assurance.

Wine industries commonly use concrete and stainless-steel tanks in fermentation, but the selection of a container depends on factors such as price, installation costs, requirements, maintenance costs, and monitorability. However, nowadays environmental protection trends seek to care for the environment along the entire value chain, consequently, making industries more responsible for managing aspects, such as pollutant emissions, resource consumption, and energy consumption. This paper reports a comparative cradle-to-grave life cycle assessment of the two most common types of containers for wine fermentation, i.e. stainless-steel tanks and concrete tanks. The present study estimates the environmental impact from building, installation, and dismantling of tanks to analyse the environmental impact from alcoholic fermentation and malolactic fermentation. Results indicate that building the tank – either out of concrete or stainless steel – has a high impact on the environment, for instance, in terms of global warming impact per liter of wine 6.03E-02 kg CO2 equivalent from steel tank or 1.31E-02 kg CO2 equivalent from concrete tank (ratio is 4.6). In addition, the building stage in a concrete tank has the highest environmental impact due to the concrete consumption and low recycling rate, while in stainless-steel tank, the fermentation stage is the highest environmental impact mainly due to direct CO2 emissions and because it has a high recycling rate.

Photovoltaic technology has become a key strategy to achieve the European goal of renewable energy rate. But the photovoltaic market is not uniform in the European Union, with different support policies in each country. These policies, if are stable and suitable over a period, can influence investment decisions and ensure a profitability in the investment. This paper studies the profitability of photovoltaic self-consumption installation in Spanish households with Spanish regulations. To develop this study, the electric consumption profile of houses was considered. The difference in profitability has been analyzed according to the number of members of the household. Furthermore, the impact of the adoption of another type of self-consumption support policy has been analyzed (France, Germany, Italy, Great Britain, and Finland). For this, all incentives have been scaled up to the Spanish price. The result is that all these regulations present significantly better profitability than the Spanish, leading to it being considered that the investments have very positive economic parameters. For instance, the payback period in Spain for households of 1–4 members is 21, 17, 16, and 15 years respectively, while in the worst of the other analyzed countries these values are 13, 11, 10 and 10 years.

This Special Issue is continuation of the work published in 2018 with the same name [1]. As is expected, the control or behavior knowledge of factors that influence on the production performance continues to be important in the academic and industrial field. Thus, new algorithms are developed to reduce the uncertainty and improve the efficiency in machines [2], processes [3, 4], and even the supply chain [5], and new methods are proposed to know the relationship among production factors in some sectors [6, 7] or more specific as in assembly lines [8]. In this context, the communication technologies and the advanced manufacturing technologies could be considered because they affect the performance and facilitate to monitoring the production process [9, 10] or new customized product configurations [11].

Poor workstation designs represent a risk factor for operators in assembly production lines. Anthropometric design of workstations facilitates the sustainable development of the workplace. This paper proposes a novel integrated approach about work standardization and anthropometric workstation design as a strategy to increase human factor performance as well as the productivity index in manufacturing companies. The integrating approach is presented through a case study in a publishing press company with operators who perform manual and mechanical tasks in production lines in the box assembly department. Currently, the company’s production capacity is below demand, and in order to satisfy customers’ requirements, the company pays a lot of overtime to operators. In order to solve this problem, the integrated approach was applied. The findings indicated that inefficient movements and body postures in operators decreased from 230 to 78, and the standard time was reduced from 244 to 199 s for each assembled box. In addition, the production rate increased by 229 units per assembly line per day, and overtime was eliminated. Therefore, the novel integrated approach allows the increase of sustainability in the company and the operators’ well-being by making a better use of the human factor, eliminating overtime, and increasing production capacity.

Higher Education Institutions (HEIs) are dedicated to the professionalization of human capital; to accomplish this, the link with the productive sector is an active component that must be strengthened through formal mechanisms. The purpose of this paper is to estimate the relationships and effects from the Institutional Framework (IF), as well as from the independent variables in the context of linking HEI with the industrial sector. Survey data were collected from 47 HEIs in the Northwest of Mexico; a mixed research approach was applied and analyzed through the partial least-squares structural equations modeling (PLS-SEM) technique. Although the IF is identified as a relevant aspect for the model, this is not a problem for Mexican HEIs, since the analysis reflects a solid legal framework regarding the common basic levels and research. The main impact for experts who carry out research activities is that the route to creating, maintaining, and promoting integrated academic, technical, and administrative personnel as a specialized work team is not achieved. The main factor that does not contribute for researchers who carry out research activities is that the route to integrating (creating–maintaining–promoting) academic, technical, and administrative personnel as a specialized work team is not achieved. One finding is that the informants agree with the existing stimuli that are not aimed at research linked to the industrial sector and problem-solving through applied research. There is a need for retaining the groups of researchers to help make the benefits for the industry clear by offering advanced linkage levels.

This paper reports the life cycle analysis (LCA) of the replacement of a conventional boiler by a geothermal boiler in a standard, medium sized, single-family dwelling, located in a Mediterranean country such as Spain. The geothermal installation analysed is vertical, with two wells of 0.66 m diameter and 125 m depth each. This type of vertical wells has been chosen due to the smaller surface area required compared to horizontal collectors. The LCA studies the costs of the different phases, as well as the costs of the final installation. The system boundaries considered during the study cover the overall production for the creation of a functional unit in a gate-to-gate study. Findings indicate that the greatest environmental impacts are in Marine Aquatic Ecotoxicity category and the lowest corresponds to the Ozone Layer Depletion category. Regarding the phases, the drilling phase has the highest environmental impact and the second one is the boiler installation, while the lowest impact is found in the installation of probes. Finally, an amortisation analysis for environmental impact is developed, concluding that all categories are amortised in 8 years and some of them in less than 3 years.

We compare four techniques that are commonly used for cleaning and disinfection of oak wine barrels with 225 l of capacity used in the red wine aging process through a life cycle analysis (LCA). The analysed techniques were pressurised water (at 90 °C) plus sulphur dioxide (SO2) wick (7.5 g per barrel), water vapour (at 105 °C) plus sulphur dioxide (SO2), ozone (O3) (4 ppm), and carbon dioxide (CO2) (50 kg/h for 180 s). The results showed that the barrel cleaning technique with the lowest impact on all water scarcity indexes and is the carbon dioxide, due mainly to low water usage. However, in the global warming category, carbon dioxide technology is the technique that has the greatest environmental impact with a value of 4.080 kg CO2 per cleaned barrel, due mainly to CO2 and air consumption.

The determination of electricity consumption profiles in the domestic sector is a very complicated task due to the variability of the consumer. This sector covers a wide variety of sizes and types of consumers; it has, as well, a wide variability in the occupancy of homes, and therefore, the measurement of final consumption has a very high cost. In this article a new bottom-up stochastic simulation model is presented, nourished by data provided by the Survey of Time Employment of the National Institute of Statistics of Spain (INE). The algorithm permits an estimation of the average profile of regular electricity consumption in Spain according to the number of members of the house and the day of the week. Unlike some previous research, the average profile is studied, and all household uses are separated. These results are the basis of a line of research on self-consumption, but they are also useful as the basis for many other studies on energy consumption, energy efficiency, demand management, hourly rates, energy policies, etc.

This paper presents a structural equation model that relates knowledge coordination with access to information in the process of implementing Six Sigma and their impact on the quality and economic benefits obtained. The model integrates four latent variables (knowledge coordination and access to information as independent variables; quality benefits and economic benefits as dependent variables), that are intertwined by five hypotheses validated statistically through the partial least squares technique using data from 301 responses to a survey applied in the maquiladora industry. Findings suggest that to obtain benefits associated with product quality, information and knowledge acquired from Six Sigma, projects must be carefully saved, managed, and analysed with appropriate statistical techniques applied by green and black belts. However, to obtain economic benefits, the information and knowledge must be transformed into benefits associated with quality such as reduction in delivery time, reduction of customer complains and compliance with standards demanded by the customer.

When wood comes into contact with wine, organoleptic properties valued in oenology are generated, which are lost over time and barrels use, so alternative processes are currently used into old barrels as adding wood chips, sticks and staves for keep those properties; however, the environmental and economic impact of the use of these alternatives is not known. This article presents a life cycle assessment (LCA) and economic analysis for those common alternative process used for keep organoleptic properties, but using barrels additives from Quercus alba and Quercus petraea wood. The ISO 14040 standard is employed for the LCA in Simapro® software, making use of the CML-IA baseline V3.04/EU25 methodology and for the economic analysis the production cost is used. The results indicate that aggregating wood chips to recover the organoleptic properties on wine is the alternative that generates less environmental impact and the least expensive, while the highest environmental impact and cost are produced when using wood slaves. On the other hand, additives from Quercus alba wood are less expensive and present low environmental impact in relation to those from Quercus petraea.

This paper reports a case study using a standardization process for increasing efficiency and a better optimization of resources in a printing company with 150 operators having manual and mechanical tasks in the box assembly department along with four production lines. The current capacity is 350 boxes per day, while the demand is 650 units, where the company is expected to pay large sums for overtime. Using work standardization, studying worker movements, timing, and workstations redesign, the main goal was to increase the efficiency and productivity indexes. After applying those tools, the inefficient movements in operators decreased from 230 to 78, eliminating 66% of the unnecessary movements, as well as the standard time in a workstation decreased from 244 to 199 s (18.44%) per each assembled box, and the production rate increased by 63.2%, that is, 229 units per assembly line a day, where overtime was reduced to zero.

Advanced manufacturing technologies (AMT) require considerable investments that managers often avoid, which makes it difficult to link their production operations with the benefits reported in literature review. The present paper shows a structural equation model that integrates four latent variables to measure the relationship between the levels of advanced manufacturing technologies implementation (Stand-Alone Intermediate and Integrated Systems), as well as the benefits obtained in the productive systems. The variables are related to each other using six hypotheses in order to realise how the AMT implementation level affects the benefits obtained from a quantitative and statistical point of view. The model is evaluated through the partial least square technique with data from 383 responses to a survey. Findings show that Stand-Alone Systems contribute more to obtaining Production Benefits, followed by Integrated Systems and Intermediate Systems. Finally, a sensitivity analysis based on conditional probabilities was performed to evaluate scenarios at different implementation levels in AMT to know how they facilitate the acquisition of the benefits offered.

The purpose of universities, apart from produce qualified professionals with problem-solving capabilities and soft-skills, should be to develop the social responsibility sense on their students. In this context, our proposal combines project based learning (PBL) and service based learning (SBL) along with gamming and the use of open-source machines, with the aim to increase student’s motivation and their social commitment with an affordable budget. The strategy, from now on named OS-PBL-SR (Open-Source-based PBL projects with Social Responsibility), mainly includes three important aspects: (i) assignment with projects orientated towards a social benefit; (ii) development of the projects using open-source Do It Yourself desktop machines (DIY-DkM); and (iii) include gamming in the evaluation method. The strategy was applied in the subject Manufacturing Technology but it might be easily exportable to other technical subjects. The results from the last academic year are presented. Also, a new OS-PBL-SR proposal aimed to the design and fabrication of autonomy-oriented products for people in a dependency situation is presented. The results showed the beneficial impact on undergraduate students by keeping high levels of motivation reflected on excellent success rates and scores. In addition, essential advantages in the use of DIY-DkM were found regarding the implementation of this kind of PBL strategy.

This article reports a structural equation model (SEM) with four latent variables to measure the relationship between information and communication technologies (ICT) integration with supply chain flexibility, supply chain agility, and company’s performance. The SEM integrates six hypotheses with relationships among variables and is validated with 378 responses from manufacturing sector to a questionnaire and partial least squares technique is used to evaluate it and test the hypotheses statistically. A sensitivity analysis is conducted in different scenarios to know conditional probabilities of occurrence of dependent variables, since a scenario has occurred in the independent variable with low and high success level. Findings indicate that ICT integration in supply chain facilitate to monitoring the production process, partners integration and have a direct effect on agility and flexibility for manufacturers, providing an active material’ or subassemblies’ flow among partners with greater visibility and making agile and joint decision-making.

A successful Just in Time (JIT) implementation is based on human resources integration (managers, operators and suppliers) and other lean manufacturing techniques applied in the production process. However, the relationship between these variables is not easily quantified. This paper reports a structural equation model that integrates variables associated with JIT implementation: management commitment, human resources integration, suppliers and production tools and technique, which affect the benefits gained, and are integrated into nine hypotheses or relationships among then. The model is evaluated with information from 352 responses to a questionnaire applied to manufacturing industry, and partial least squares technique is used to evaluate it. The direct effects, sum of indirect effects, and total effects are quantified, and a sensitivity analysis based on conditional probabilities is reported to know scenarios associated with low and high levels in variables’ execution and how they impact the benefits obtained. Findings indicate that managerial commitment is the most important variable in the JIT implementation process, since managers are the ones that determine the relationships with suppliers, integrate human resources, and approve the lean manufacturing techniques and tools that support the JIT.

This paper demonstrates how it is possible to combine SMED with Centerlining in complex production environments with numerous changes of format, product, raw materials and tools. This research proposes a methodology involving an initial application of Centerlining and, once the machinery and the process are stable, the subsequent implementation of SMED. Furthermore, it aims to show that it is possible to achieve improved output and reduced machinery changeover time while ensuring that the effect achieved by SMED is more stable. This increases the organizational advantages with respect to the implementation of SMED without prior application of Centerlining. The most important overall conclusion is that a successful application of SMED must always be accompanied by another type of tool or technique to maximize the results of its application. And, as presented in this work, one technique that enables significant improvements to SMED is the application of Centerlining.
