Résumé
The concepts of short agri-food supply chains and circular bioeconemy are complementary and mutually reinforcing, while they may play an important role in sustainability transitions. The elimination of middlemen and the possibilities of forward vertical integration of farmers are the key components ofshort agri-food supply chains, while bioeconomy refers to the sustainable production and use of biological resources stemming from forestry, agriculture, fisheries, and waste streams. The development of closed-loop systems where waste is converted into new resources, lies in the core of circular bioeconomy, which seeks to reduce waste and maximize resource usage. A sustainable and regenerative economy where waste is viewed as a resource and the use of finite resources is decreased is what this strategy seeks to achieve. When combined, short agri-food supply chains and circular bioeconomy can support sustainable economic growth, social advancement, and environmental protection by encouraging local manufacturing, minimizing waste, and developing innovative bio-based goods and procedures. In this article, we examine the benefits which occur in short agri-food supply when they adopt the principles of circular bioeconomy. Also, we examine how can the ideas of the circular bioeconomy be applied to short agri-food supply chains in order to minimize waste and maximize resource usage. In addition, we explore the corresponding difficulties and opportunities for creating bio-based goods and procedures in short agri-food supply chains. Last but not least, we discuss the effects of short agri-food supply chains and the circular bioeconomy on global agri-food systems and how these concepts are connected with issues at stake, such as food security and sustainability.
Résumé
Urbanization of coastal areas worldwide has increased due to an increase in the global population. The production of sustainable aquaculture is greatly impacted by a surge of this urbanization. In certain countries, particularly for individuals with more limited space in metropolitan areas, such as along Johor's coastal area, aquaculture might well be a good strategy to maintain food availability (continuous production plus high-quality meals). Consequently, the adoption of aquaculture along the Johor's coastal area has lead to Harmful Algal Blooms (HAB). This paper examines the evolution of the aquaculture industry of Malaysian Johor coastal areas in relation to HABs. In addition to HABs, the aforementioned metropolitan regions confront diverse economic and geographical obstacles when attempting to increase their aquaculture production sustainably. Those problems are therefore addressed using a variety of operations as well as surveillance techniques in this brief overview. Lockdowns and border prohibitions caused by the continuous COVID-19 infection have had a global impact. These logistical difficulties in the seafood industry have increased dependency on imported supplies. It is suggested that international decision- making, supervision, and knowledge exchange can successfully solve the challenges urbanized areas have in ensuring sustainable food security through the evolution within the aquaculture sector.

PurposeSustainable supply chain management (SSCM) ensures integration of socially, environmentally and economically feasible practices in entire supply chain. SSCM principles can be implemented to improve efficiency and productivity of a system by different attributes of the system. The purpose of this article is to identify the most appropriate existing (SSCM) framework that can be implemented suitably in Indian smart manufacturing industries.Design/methodology/approachValidity and reliability analysis on the existing SSCM frameworks was carried out with the help of empirical data collected using questionnaire survey methodology from various Indian smart manufacturing organizations. The empirical data were gathered from various experts from top- and middle-level management in different smart manufacturing organizations across the country. Further, factor analysis was carried on the collected data to estimate the unidimensionality of each SSCM frameworks. Cronbach's alpha value was used to assess reliability of each framework. Subsequently, the frequency distribution analysis was done to obtain familiar elements in the segregated frameworks based on validity and reliability analysis.FindingsThe work observed that only five SSCM frameworks have shown unidimensionality in terms of the elements or constructs. The work further found that these segregated frameworks have not shown sufficiently high level of reliability. Additionally, this work attempted frequency distribution analysis and observed that there were very few elements which were being repeatedly used in numerous frameworks proposed by researchers. Based on the findings of this work, the work concluded that there is acute need of a new SSCM framework for Indian smart manufacturing industries.Research limitations/implicationsThis study gathered empirical data from 388 Indian smart manufacturing organizations. Thus, before generalizing the findings of the study across the sectors, there is a possibility of some more explication.Originality/valueThe main purpose of this article is to explore the feasibility of the existing SSCM frameworks in Indian smart manufacturing sector. The study also assumes that the manufacturing managers and executives may have the complete understanding on the existing sustainable manufacturing frameworks and a chance to executing proper suitable framework in the respective manufacturing organization.
Résumé
The current global health crisis caused by the SARS-CoV-2 virus (COVID-19) has increased the use of personal protective equipment, especially face masks, leading to the disposal of a large amount of plastic waste causing an environmental crisis due to the use of non-biodegradable and non-recyclable polymers, such as polypropylene and polyester. In this work, an eco-friendly biopolymer, polylactic acid (PLA), was used to manufacture hierarchical nanoporous microfiber biofilters via a single-step rotary jet spinning (RJS) technique. The process parameters that aid the formation of nanoporosity within the microfibers were discussed. The microstructure of the fibers was analyzed by scanning electron microscopy (SEM) and a noninvasive X-ray microtomography (XRM) technique was employed to study the three-dimensional (3D) morphology and the porous architecture. Particulate matter (PM) and aerosol filtration efficiency were tested by OSHA standards with a broad range (10-1000 nm) of aerosolized saline droplets. The viral penetration efficiency was tested using the phi X174 bacteriophage (similar to 25 nm) with an envelope, mimicking the spike protein structure of SARS-CoV-2. Although these fibers have a similar size used in N95 filters, the developed biofilters present superior filtration efficiency (similar to 99%) while retaining better breathability (<4% pressure drop) than N95 respirator filters.
Résumé
The study ascertained the relationship between aquaculture production and greenhouse gas (GHG) emissions in South Africa. The study used the Autoregressive Distributed Lag—Error Correction Model (ARDL-VECM) with time series data between 1990 and 2020. The results showed that the mean annual aquaculture production, GHG emissions, and Gross Domestic Product (GDP) in the period were 5200 tonnes, 412 tonnes, and US$447 billion, respectively. There was a long-run relationship between GHG emissions and GDP. In the short run, GHG emissions had a positive relationship with GDP and a negative relationship with beef production. Furthermore, there was a bi-directional relationship between aquaculture production and GHG emissions. In addition, beef production and GDP had a bi-directional relationship. Beef production also had a positive relationship with aquaculture production. The study concludes that aquaculture production is affected and tends to affect GHG emissions. Aquaculture legislation should consider GHG emissions in South Africa and promote sustainable production techniques.
Résumé
Businesses reeling from the impact of COVID are struggling to achieve sustainability, amidst many other challenges, including finance and capacity shortfalls. One of the pathways to achieving 3BL in businesses is to create closed-loop supply chains (CLSC) covering the entire lifecycle of products. CLSC have proven to be important for sustainable supply chain (SC) operations, given the shortage of materials and labour globally following the COVID-19 pandemic. While it is widely acknowledged that the success of CLSC depends on successful collaboration between SC members, factors for successful CLSC collaboration are not sufficiently understood from the literature. Employing an observation-based case study and a survey of SC members, we develop our contribution in the context of an Indian packaging company, to delineate and verify a collaborative CLSC framework. The results confirm that the success of CLSC collaboration lies in the involvement and commitment of SC members. Collaboration for forward and reverse SC operations also facilitate the involvement of SC members in CLSC collaborations. Our research suggests that SC collaborations are enhanced by explicit incentive-sharing schemes and having the same SC members for both forward and reverse SC operations. © 2023 The Authors

Résumé
The Summer Academy in Sustainable Manufacturing is an NSF Research Experience for Undergraduates (REU) Site that offers unique summer undergraduate research experiences in the challenging field of sustainable manufacturing to national undergraduate students from two and four-year institutions. The objective of the REU Site is to introduce undergraduate students to the forefront of sustainable manufacturing research and to provide participants with the skills and pathways to pursue advanced degrees or careers in sustainable manufacturing. The intensive ten-week summer research and professional development experience hosts ten students per summer and addresses National Science Foundation priority areas such as advanced manufacturing and sustainability. Undergraduate research projects in the REU site address manufacturing process, manufacturing system, and fundamental sustainable manufacturing principles within continuous (e.g. chemical manufacturing) and discrete (e.g. automotive manufacturing) manufacturing systems. Projects are further associated with topics that cross cut the aforementioned thrust areas such as, emerging and environmentally benign materials manufacturing, sustainable process design and control, and life-cycle engineering and value recovery. Traditionally, this REU Site hosts in-person undergraduate researchers to undertake their research projects in a faculty mentor laboratory during the program. However, the COVID-19 pandemic necessitated that the REU Site program be held virtually during the summer of 2021. This poster and summary paper detail the steps taken to transition REU Site program activities to a virtual environment and post-program evaluation results of participant experiences. Evaluation results of the virtual program are compared to evaluation results of prior in-person Summer Academy in Sustainable Manufacturing programs. © American Society for Engineering Education, 2022.
Résumé
The aim of the paper is to conduct research and present the results of a taxonomic analysis assessing the 2019 and 2020 implementations of socio-economic sustainability goals in the Lubuskie Province as compared with other Polish regions. To this end, a multidimensional comparative analysis was performed to determine the level of socio-economic development of the Lubuskie Province and then benchmark it against other regions in the context of sustainable development. The research was based on independent indicators developed with the use of linear ordering methods and accounting for aspects of socio-economic development such as the economic potential, innovation of the economy, sustainable production patterns, demographic changes, job market, and social integration. Synthetic measures were developed with the use of the proposed partial indicators (independent variables), which, according to the authors, best illustrate the socio-economic development and sustainability at the regional level. The regions were then grouped by level of economic development, and the groupings were assessed for their performance. The research shows that in 2020, compared to 2019, the overall level of economic development deteriorated in all Polish regions, but the pandemic has so far had significantly less impact on the social area.
Résumé
The purpose of this study is to examine and compare different psychological and sociodemographic factors for contracting sweet potato production for farmers with different statuses based upon the theory of planned behavior (TPB). Sustainable production provides contract owners with a sufficient amount of both food crops and a source of bioethanol clean energy. The impact of such factors on potential farmers based on the TPB for a particular contract type is estimated with the data collected in three major sweet potato production cities/counties in Taiwan through the probit model and multinomial logit model. The average size of the surveyed farms is 1.64 ha. The results consistently show that the factors of attitude toward the advantages of contract farming, subjective norms regarding contract farming, perceived contract farming control, and behavior intention have very significant impacts on the selection of contract farming types for professional farmers and brokers. These results indicate that the contract owners will gain the greatest advantage through commanding any factor in TBP for these two groups of farmers, as they have an incentive to manage the sources of sweet potatoes at the best conditions before they have the agreement with the contract owners, either as the supply of bioethanol energy raw materials, supply of food crops, or supply of food processing materials.

Fossil fuels, agriculture and deforestation The first priority must shift trillion-dollar fossil fuel subsidies into the renewable energy sector. Agriculture is also one of the biggest carbon emitters, with huge inputs of fossil fuels involved in manufacturing pesticides and fertiliser, plus processing, packaging and distribution.
Résumé
Since the mid-2010s, the circular economy has emerged as a key conceptual lever in corporate efforts to achieve greater environmental sustainability. Corporations have increasingly drawn upon the circular economy perspective in efforts to rethink sustainable supply chain management practices. This new corporate approach to sustainable supply chain management is evident in an emerging literature that has yet to be fully documented. In this systematic review of research, bibliometric methods were applied to a database of 709 Scopus-indexed documents. Author co-citation analysis identified four schools of thought comprising the intellectual structure of this literature: Sustainable Production and Environmental Management, Sustainable Supply Chain Management, Reverse Supply Chain Management, and Circular Economy. Synthesis of these themes suggests that the adoption of a circular economy perspective is transforming sustainable supply chain management in two important ways. First, this perspective reorients supply chain management away from a narrow focus on efficiency and waste reduction and towards a new paradigm of redesign, reuse, and product transformation. Second, adoption of the circular economy highlights and leverages reverse cycles in the supply chain. Thus, circular economy business models enable supply chain management to enhance corporate contributions to sustainable production and consumption. Drawing upon this framing of supply chain management within a circular economy, the review proposes a new framework for accelerating corporate sustainability.
Résumé
Context: Food safety is essential for every human. It determines public health, nutrition, elimination of hunger, and the promotion of sustainable agriculture. It is crucial for sustainable production, consumption, and international food trade. Ensuring food safety is the fundamental challenge of the 21st century. Food safety is often related to food defense and includes protection against intentional contamination with various chemical, biological, or other harmful substances. By introducing food protection tools and methods, any company reduces risk and creates an opportunity to generate more significant and reliable profits and improved production for society. One such method could be the CARVER+Shock. The method is an offensive targeting prioritization tool that has been adapted for use in the food sector. Objective: The article aims to present the experience of the first implementation of CARVER+Shock in a Polish primary production company, to improve the approach to food safety and food defense. Methods: The article is a case study. Descriptive analysis was performed to analyze legal acts and safety management standards in food defense. The authors used the CARVER+Shock expert method to estimate companies’ vulnerability. CARVER is an acronym for Criticality, Accessibility, Recoverability, Vulnerability, Effect, Recognizability. The visualization and risk analysis were made using business process management and business process modeling (VACD diagram) Results and conclusions: Primary production enterprise dealing with the cultivation and confectioning of the pre-treatment and sale of peeled onions for further processing purposes was examined. Five essential stages of the production process were assessed, and risks were assigned. Recognizability and criticality turned out to be the most crucial attribute of CARVER+Shock. Overall, the study showed that the company was not fully prepared for the threat posed by food terrorism. The organization did not have any procedures describing how to proceed during deliberate attacks. In addition, workers had low awareness of food defense throughout the food chain. Based on these conclusions, several detailed improvement actions were formulated. The results obtained from the pioneering application of the CARVER+Shock method for a Polish primary production company may constitute a benchmark for other sectors of the food industry, both domestically and abroad. Significance: The article describes the results of the first Polish attempts to use CARVER+Shock and business process management to improve the approach to food safety in a primary production enterprise.
Résumé
Demand forecasting plays a crucial role in a company’s operating costs. Excessive inventory can increase costs and unnecessary waste can be reduced if managers plan for uncertain future demand and determine the most favorable decisions. Managers are demanding increasing accuracy in forecasting as technology advances. Most of the literature discusses forecasting results’ inaccuracy by suspending the model and reloading the data for model retraining and correction, which is extensively employed but causes a bottleneck in practice since users do not have the sufficient ability to correct the model. This study proposes an error compensation mechanism and uses the individuals and moving-range (I-MR) control chart to evaluate the requirement for compensation to solve the current bottleneck using forecasting models. The approach is validated using the case companies’ historical data, and the model is developed using a rolling long short-term memory (LSTM) to output the predicted values;then, five indicators are proposed for screening to determine the prediction statistics to be subsequently employed. Root mean squared error (RMSE), mean absolute percentage error (MAPE), and mean absolute error (MAE) compare the LSTM, rolling LSTM combined index, and LSTM-autoregressive moving average (ARMA) models. The results demonstrate that the RMSE, MAPE, and MAE of LSTM-ARMA are smaller than those of the other two models, indicating that the error compensation mechanism that is proposed in this study can enhance the prediction’s accuracy.
Résumé
The Kingdom of Plantae is considered the main source of human food, and includes several edible and medicinal plants, whereas mushrooms belong to the Kingdom of fungi. There are a lot of similar characteristics between mushrooms and higher plants, but there are also many differences among them, especially from the human health point of view. The absences of both chlorophyll content and the ability to form their own food are the main differences between mushrooms and higher plants. The main similar attributes found in both mushrooms and higher plants are represented in their nutritional and medicinal activities. The findings of this review have a number of practical implications. A lot of applications in different fields could be found also for both mushrooms and higher plants, especially in the bioenergy, biorefinery, soil restoration, and pharmaceutical fields, but this study is the first report on a comparative photographic review between them. An implication of the most important findings in this review is that both mushrooms and plants should be taken into account when integrated food and energy are needed. These findings will be of broad use to the scientific and biomedical communities. Further investigation and experimentation into the integration and production of food crops and mushrooms are strongly recommended under different environmental conditions, particularly climate change.
Résumé
The article deals with the possibility of using augmented reality on the principle of marker target for student education. The whole proposed concept consists of the principle of displaying 3D models of machines, equipment, robots, conveyors, and accessories above the markers depicting an actual device. The first part of the article was focused on the 3D model software tools and was presented a step-by-step procedure for creating an AR application. We will describe a specific strategy for building a 3D model, creating a marker in the Vuforia engine interface. Subsequently, the procedure for working in the Unity development interface up to the final export of the final application was presented. The second part of the article was focused on the developed application and the possibilities of its deployment in the educational process. The initial tests were used by university students on the subject “Digitalisation of Production and Services”. The gained results show the innovativeness of the proposed solution. In this article, an AR application was implemented in the educational process as a new distance education tool during the COVID-19 pandemic. This new way of presenting 3D models using AR falls under the concept of Industry 4.0, which is becoming a necessity today and brings many benefits in education and practice. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
Résumé
The article focuses on the definition of risk management in industry, which is linked to developing an automated diagnostic and inspection system based on artificial intelligence designed to eliminate risks in industrial companies. The thesis outlines the risk management process according to the current ISO standard, and the following section of the article summarizes the risk management options available to businesses. The article also discusses the numerous strategies that can be used to lessen the risk of working with automated systems in industrial settings. A critical element in the spread of COVID-19 is the failure to maintain a sufficient distance between people (workers) and the late detection of the symptoms of this disease. Monitoring unjustifiable aggregation of workers and early detection of symptoms such as characteristic cough and temperature makes it possible to reduce or significantly eliminate the spread of this disease in the engineering company. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
Résumé
The rapid ongoing digital transformation creates new opportunities to generate value but also challenges companies in the manufacturing industry to adapt to the recent changes. Moreover, committing to sustainability is essential to maintain competitive advantages, build a more resilient company, and manage increasing societal demands and regulations. Referred to as a “twin transition”, the digital transformation can positively impact firms’ commitments to environmental sustainability. This paper explores challenges that small technology solution providers face on their path toward developing sustainable production solutions for their manufacturing customers. An empirical study was conducted in an industrial cluster of small and medium-sized companies (SMEs) providing innovative, tailor-made production technology solutions to manufacturing companies. As a result, a collaborative process model was suggested for such SMEs to overcome internal and external barriers to obtaining sustainability, thus better supporting the manufacturing companies, i.e., their customers, to strive towards more sustainable production.
Résumé
Renewable energy communities (RECs) are alternatives toward sustainable production and consumption pathways. In 2020, Italy implemented the EU Directive 2018/2001, defining a common framework for promoting energy from renewable sources. The “Famiglia di Maria”, a foundation dealing with social issues in San Giovanni a Teduccio, Napoli (Italy), in collaboration with “Legambiente” and “Con il Sud” Foundations, released the first Solidarity Oriented Renewable Energy Community project in Italy. Therefore, by applying social life cycle assessment (s-LCA) and life cycle assessment (LCA) methodologies, this study aims to: (i) promote the dissemination of RECs in the Italian and European contexts, (ii) suggest REC scenarios for the best social and environmental solutions, and (iii) support the policymakers for sustainable local development. Some key results show that the solidarity-oriented project has already produced mature outcomes about community cohesion. In contrast, technical skills and awareness about environmental issues still need to be further developed and shared among the stakeholders. Finally, social and environmental indicators converge on the self-consumption model as a feasible alternative for energy justice, community empowerment, and economic and market competition independence.
Résumé
Changing business models is a topical issue in a pandemic. Recent research has shown that the search for environmentally friendly and sustainable solutions in various sectors has become relevant. The article aims to promote cooperation and adaptation of good practices between countries. Comparing the country’s history and economic situation and economic development and traditions can be seen as a precondition for success. The article examines the introduction of sharing economy and the creation of environment-friendly trends establishing a circular economy by minimizing the population’s expenses, online business growth, and accessibility of Internet technologies. The article explores the difference between the linear economic model and the circular model by adopting sharing and the efficient joint use of materials to enhance and assess sustainable development. Based on a combination of theoretical and practical research, the article explores the dynamic system and development model of sharing a circular economy. The new concept of circular economy does not promote the overproduction of new goods but the rational use of already produced ones, which significantly reduces the amount of waste generated at all stages of the product life cycle. Population groups by different income groups for sharing services are analysed. An analysis of the price characteristics of popular sharing products was used from data from Internet portals. One concludes that due to the increase in Internet users, especially mobile apps, and social networks, C2C sharing has become quite popular over the past years. Other areas also show positive development indicators but have less demand, affecting supply. Based on an in-depth study of the economic situation in Ukraine, the authors have critically chosen an industry to set as an example with the actual business situation. Therefore, three packages were created: pessimistic, standard and optimistic ones with different characteristics of implementing circular economic projects. The chosen method allows rational management decisions for attracting financing and sustainable solutions. The company’s business scenarios analysed in the article will allow to choose a system based on circular economy principles successfully.
