Energy Efficiency in the Food Industry: A Systematic Literature Review

Abstract Governments and private companies have increased efforts to identify effective actions for improving energy efficiency in manufacturing processes. The objective of this work is to improve the decision-making process by increasing the quality of information related to energy indicators in the food industry. This research involves developing a systematic literature review (SLR) to identify energy efficiency indicators in the food industry, which serve as inputs for a sectoral evaluation based on multicriteria techniques. The SLR identified six criteria evaluated by food industry experts, which form the proposed basis for evaluating the performance of related sectors. These criteria are: benchmarks, key performance indicators, framework, monitoring, ISO 50001, and information communication technologies (ICTs) in sectoral evaluations. The criteria were evaluated by experts using the Analytic Hierarchy Process (AHP), which prioritizes the most important food industry issues using an evaluation scale. Weights were attributed to each issue and positioned according to the Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) to evaluate each sector by the identified criteria. The evaluated criteria are applicable to the three sectors surveyed, with emphasis on the beverage sector. Among the evaluated criteria, ICTs were highlighted by Industry 4.0 as a concern for the food sector.

Energy Management in Energy-Intensive Industries: Developing a Conceptual Map

Abstract This paper presents the development of a conceptual map regarding energy management applied to industry. The energy issue is currently of great relevance, especially for the so-called energy-intensive industries related to high energy consumption and their associated environmental impacts. The present research is characterized as a basic, exploratory approach justified by the need to build knowledge on the subject of energy management in industry. The methodology provides for the use of a computational tool called CMap Tools, which assists in the graphic representation of the proposed conceptual map. The conceptual map based on the ISO 50001 standard and on successful energy management practices described in the scientific literature is directed toward a process design covered by the managerial discipline called Business Process Management. The conceptual map is intended to clarify the relationships that are established between the intra-organizational and main external stakeholders involved in an energy management system. Owing to the way internal areas and external organizations relate, the representation structure using a "Spider" is the most appropriate. The work developed presents an energy management system for an energy-intensive industry in a clear (conceptually and visually), orderly, unified, harmonious, and balanced manner indicating the distribution of its elements, and serves as an initial step in the creation of an ontology for this area of knowledge.

Energy Management in Industry: An Enterprise Engineering Approach

ABSTRACT Companies have needs and experience new opportunities to build their structure and align organizational process to achieve energy management with higher priority facing economic and environmental issues. The objective of this paper is to present the design and modeling of the Energy Management System (EnMS) in energy-intensive industries in an enterprise engineering approach, according to the management discipline called Business Process Management (BPM). The design of the process is based on the ISO 50001 standard and in good practices cited in the scientific literature. The methodology is characterized as basic, experimental, qualitative, and oriented according to the BPM development cycle. The process design created in the "should be" format presents a framework based on the Plan, Do, Check and Act (PDCA) cycle. The process is described in a necessary and sufficient way, arranging activities, actors and roles to establish an energy management process. The key process model of the energy review was developed in the Business Process Model and Notation (BPMN). The design and modeling allows to: analyze the EnMS as a process for understanding the activities; assist decision making; automate processes; enable collaboration; allow alignment of the process with the strategy; support the change and assisting with the evaluation of the organizational potential to implement the EnMS.
