Abstract: Purpose: Food waste is a latent problem for society, one of the main causes being poor management of the operating processes within the food industry, which is the main reason the present research aimed to reduce raw material waste in a nectar factory.Design/methodology/approach: The methodology led to carrying out an experimental investigation where a Green Lean Six Sigma Model was applied, whose foundation was the use of tools such as Environmental Value Stream Mapping (E - VSM), DMAIC (Define - Measure - Analyze - Improve - Control), Poka Yoke and DOE (Design of Experiments), the data obtained were exposed to an inferential statistical analysis using tests such as Anderson - Darling and T-Student.Findings: As a final result, a waste reduction of 2.23% was obtained, which is equivalent to approximately 120 kg of useful raw material, in addition the environmental impact was reduced by 2.2%, waste costs were also reduced by approximately 5.5% and produced an increase in global productivity by 2.4%.Research limitations/implications: It is shown that the application of methodologies such as Green, Lean and Six Sigma in the food industry present benefits during and after the application of the model; such as preventive control of waste, standardization in processes; benefits that, in coordination with an organizational culture of continuous improvement, can significantly improve the current state of companies.Practical implications: The positive obtained results support the methodology proposed by the authors to reduce the waste of agricultural raw material. It is expected to be a benchmark for other similar organizations that seek to generate greater productivity in line with the search for environmentally sustainable operations.Originality/value: This is one of the first studies that aims to reduce the waste of raw materials in food processing companies, considering aspects of mitigating environmental impact.

- Circular Clock model for circular economy implementation in firms: Balance
between theory and practice
Authors: Vanessa Prieto-Sandoval, Andres Mejia-Villa, Carmen Jaca, Marta Ormazabal
Pages: 186 - 204
Abstract: Purpose: The circular economy is a key issue for any company, city, or institution. The linear economy model, based on "take, make, use and waste" of products and resources, has discarded potentially valuable resources and caused serious contamination problems. In contrast, the circular economy (CE) model is a strategic paradigm whose purpose is to regenerate and conserve resources through closed material loops and the sustainable use of energy in its processes. Therefore, a growing number of companies are applying different tools and techniques to implement the CE principles to innovate their products, services, and processes, achieving promising results. Thus, the main objective of this study is to suggest an implementation model named “Circular clock” based on a set of tools and techniques which firms may use for implementing CE.Design/methodology/approach: The paper presents an empirical analysis based on the triangulation method that includes three different data sources: semi-structured interviews in Spain, academic literature and books, and non-academic publications from institutions and consultancy firms. Findings: The most relevant result of this study is the proposal of a Circular Clock model for circular economy implementation is based on six fields of action define in the academic literature: take, make, distribute, use, recover, and industrial symbiosis. Moreover, this study may serve as guidance in facilitating the strategic adoption of eco-innovation practices in firms' transition to a CE. Research limitations/implications: The sample of companies that participated in the triangulation is exploratory; however, this limitation is overcome by reviewing academic literature and institutional reports. On the other hand, academics could expand the selection of tools with subsequent studies.Practical implications: The current study is based on the triangulation method, which was vital to balance the theory and practice provided by academic sources, reports, and books. In addition, this study has improved our understanding of the goals or intentions that may motivate firms to implement the CE and align them with the suggested set of tools. Consequently, this study is relevant to support practitioners in selecting a tool based on the goal they want to achieve towards circular economy implementation.Social implications: This research suggests several tools; however, each organization could adapt some that it already knows. Therefore, firms and implementation leaders should customize the circle with short lines in each case. Moreover, the clock bells represent the deadline considering that every CE implementation process requires a deadline to ensure its success in micro-level or firms.Originality/value: The "circular clock" provides a didactic way for sustainability leaders, consultants, or companies to facilitate the implementation of the circular economy by choosing the field of action on which they want to focus and the most appropriate tool according to their strategy, objective, and budget. Therefore, this model is based on the balance between theory and practice.

constraints in a make-to-order environment: Integrating sales and
operation planning
Authors: Aitor Orue, Aitor Lizarralde, Unai Apaolaza, Itxaso Amorrortu
Pages: 205 - 214
Abstract: Purpose: The theory of constraints (TOC) methodology and its drum-buffer-rope (DBR) production planning and control system are well suited to managing production plants in complex environments. The objective of this study was to design an evolution of the systematic process for implementing the third step of the TOC methodology in make-to-order environments.Design/methodology/approach: Since the research concerned a real context and the phenomenon under investigation is contemporary, a case study was chosen as the research methodology.Findings: The study investigated, through a case study, the phases and steps necessary for the systematic process to be successfully implemented in a make-to-order environment.Originality/value: The three main contributions to the systematic implementation process for the third step of the TOC model are identified as the design of the last version of the systematic process, the integration of sales and operations through the TOC methodology and the introduction of the demand-driven adaptive enterprise model’s capacity buffer.

- Route planning of heterogeneous unmanned aerial vehicles under recharging
and mission time with carrying payload constraints
Authors: Kriangsak Phalapanyakoon, Peerapon Siripongwutikorn
Pages: 215 - 235
Abstract: Purpose: We consider the problem of route planning of multiple rechargeable heterogeneous UAVs with multiple trips under mission time and payload carrying constraints. The goal is to determine the types and number of UAVs to be deployed and their flying paths that minimizes the monetary cost, which is a sum of the recharging energy cost of each UAV, the UAV rental cost, and the cost of violating the mission time deadline.Design/methodology/approach: The problem is formulated as a mixed integer programming (MIP). Then, the genetic algorithm (GA) is developed to solve the model and the solutions are compared to those obtained from the exact method (Branch-and-Bound). Novel chromosome encoding and population initializations are designed, and standard procedures for crossover and mutation are adapted to this work. Test problems on grid networks and real terrains are used to evaluate the runtime efficiency and solution optimality, and the sensitivity of GA parameters is studied based on two-level factorial experiments.Findings: The proposed GA method can find optimal solutions for small problem sizes but with much less computation time than the exact method. For larger problem sizes, the exact method failed to find optimal solutions within the limits of time and disk space constraints (24 hours and 500 GB) while the GA method yields the solutions within a few minutes with as high as 49% better objective values. Also, the proposed GA method is shown to well explore the solution space based on the variation of the total costs obtained.Originality/value: The unique aspects of this work are that the model optimizes the sum of three different costs – the electricity recharging cost, the UAV rental cost, the penalty cost for mission deadline violation, and the recharging period based on the remaining energy, the payload capacity, and the heterogeneity of UAVs are incorporated into the model. The model is formulated as a mixed integer programming and the genetic algorithm is developed to solve the program. Novel chromosome encoding and population initializations are designed, and standard procedures for crossover and mutation are adapted to this work.

- Supply chain risk and its impact on performance: A structured literature
review
Authors: Thanh Hai Pham, Raffaele Testorelli, Chiara Verbano
Pages: 236 - 262
Abstract: Purpose: In the supply chain risk management literature, many reviews have been conducted to provide a full understanding of various aspects such as role of simulation and optimization methods in risk management, classification of risks, classification of risk mitigation strategies, and supply chain risk definitions. However, a structured review of risk impact on performance in supply chains is still lacking. Such a review is useful since the literature implies that maintaining and improving performance in risk environments are critically important to the business survival of firms in supply chains.Design/methodology/approach: This review synthesizes and analyses 48 papers published in journals from 2006 to 2020 based on the following criteria: risk type, impact mechanisms of risk (i.e., direct and indirect), performance, research method, research setting, and risk mitigation strategy.Findings: The findings conclude that the impact of risk on performance is complicated and influenced by many factors namely antecedents, mediators, and moderators.Originality/value: This review contributes to the theoretical development of SCRM research through the analysis of SCR impact mechanisms, and indicate gaps of knowledge and future research opportunities. Moreover, it helps managers to devise appropriate risk mitigation strategies thanks to a full understanding of risk impact mechanisms.

- Green logistic and absorptive capacity on business sustainability: The
mediating role of circular economy implementation
Authors: Muafi Muafi, Muchamad Sugarindra
Pages: 275 - 293
Abstract: Purpose: This study tests and analyzes whether: (a) Green logistics has positive effect on circular economy implementation, (b) Absorptive capacity has positive effect on circular economy implementation, (c) CE implementation has positive effect on Business Sustainability, (d) the role of CE implementation in mediating the effect of Green logistics on Business Sustainability, and (e) the role of CE Implementation in mediating the effect of Absorptive capacity on Business SustainabilityDesign/methodology: Researchers use a quantitative approach, the population is all natural-colored batik SMEs in the Provinces of Central Java and West Java. Respondents are owners/managers of batik SMEs with a target sample of 250 SMEs. Meanwhile, based on purposive sampling of data collection, it turns out that 228 SMEs are returned and deserved to be processed. The statistical technique uses Structural Equation Modeling with Partial Least Square.Findings: This study finds that there is a significant positive effect of; (a) Green logistics for circular economy implementation, (b) Absorptive capacity for circular economy implementation, (c) CE implementation for Business Sustainability. Furthermore, CE implementation mediates Green logistics for Business Sustainability, and (e) CE implementation mediates Absorptive capacity on Business Sustainability.Research limitations/implications: The implementation of the circular economy in the SMEs studied is practiced in a simple way. The role of mediation can consider other variables that are no less important in the context of batik SMEs that use natural colors. Respondents are only represented by SME groups in associations in the Klaten (Central Java) and Ciwaringin (West Java) regions, so it is feared that they would not be able to generalize the natural color batik SME population in Indonesia. It is recommended that in the future research considers longitudinal studies using the perspective of multiple respondents so that they are not subjective. Managerial Implication: Business processes in SMEs based on natural colors should consider green logistics aspects because it will have positive impact in the long term, especially on Business Sustainability. In improving SME Business Sustainability, it is necessary to conduct Absorptive capacity consistently, continue, and has consistent commitment. This is important in order to increase the competence of SMEs. When all resources are good, CE implementation practices can be more practiced by integrating with existing business processes.Theoretical Implication: This study provides enrichment to the literature on circular economy implementation in SMEs that are influenced by green logistics and absorptive capacity. The impact can make a significant contribution to increase business sustainability (business, social, and environmental performance).Originality/value: This study has its originality due to the lack of study examining circular economy implementation in the context of SMEs which is influenced by green logistics and absorptive capacity. Moreover, this study also offers a significant contribution to improving business sustainability (business, social, and environmental performance). Likewise, it also examines the mediating role of CE implementation between Green Logistics and Business Sustainability, as well as the mediating role of CE Implementation between Absorptive Capacity and Business Sustainability.
