Abstract This paper aims to develop an innovative and practical method to accelerate Pinch Analysis problems using a combination of process integration, process simulation tools, and life cycle assessment techniques to design effective industrial energy efficiency measures rapidly. Data extraction and analysis is accelerated using the workflow, reducing pinch analysis duration, and therefore cost. This lowers financial barriers and is expected to help facilitate an increase in the number of conducted pinch analyses each year. An innovative ecological targeting step has been included in the workflow, which represents the option for end-users to further their CO2 savings, once energy targeting has been completed on a purely cost basis. It is expected that optimizing for costs first will enable the implementation of heat recovery solutions in industry. The methodology is applied to an example case study, and the learnings from industrial application is reported.

Industrial Energy Efficiency

The necessity to ensure energy efficiency in the industries is of significant importance to attain reduction of energy consumption and greenhouse gases emissions. Energy management is one of the effective features that ensure energy efficiency in the industries. Energy management models are the infancy in the industrial energy domain with practical guidelines towards implementation in the organizations. Despite the increased interest in energy efficiency, a gap exists concerning energy management literature and present application practices. This paper aims to methodologically review the energy management assessment models that facilitate the assessment of industrial energy management. In this context, the minimum requirements model, maturity model, energy management matrix model, and energy efficiency measures characterization framework are discussed with implications. The study concludes with interesting propositions for academia and industrial think tanks delineating few further research opportunities.

Research And Policy

Climate change, due to anthropogenic emissions of greenhouse gases, is driving policymakers to make decisions to promote more efficient energy use. Improved industrial energy efficiency is said to play a key role in the transition to more carbon-neutral energy systems. In most countries, industrial small and medium-sized enterprises (SMEs) represent 95% or more of the total number of companies. Thus, SMEs, apart from using energy, are a major driver in the economy with regard to innovation, GDP growth, employment, investments, exports, etc. Despite this, research and policy activities related to SMEs have been scarce, calling for contributions in the field. Therefore, the aim of this paper is to critically assess how adequate energy efficiency policy programmes for industrial SMEs could be designed. Results show that scientific publications in the field differ in scope and origin, but a major emphasis of the scientific papers has been on barriers to and drivers for energy efficiency. Scientific contributions from studies of energy policy programmes primarily cover energy audit programmes and show that the major energy efficiency measures from industrial SMEs are found in support processes. The review further reveals an imbalance in geographic scope of the papers within the field, where a vast majority of the papers emanate from Europe, calling for scientific publications from other parts of the world. The study synthesizes the findings into a general method on how to design efficiency programs for the sector.

Industrial Energy Efficiency

Efficient consumption of energy and material resources, including water, is the primary focus for process industries to reduce their environmental impact. The Conference of Parties in Paris (COP21) highlighted the prominent role of industrial energy efficiency in combating climate change by reducing greenhouse gas emissions. Consumption of energy and material resources, especially water, are strongly interconnected and, therefore, must be treated simultaneously using a holistic approach to identify optimal solutions for efficient processing. Such approaches must consider energy and water recovery within a comprehensive process integration framework which includes options such as organic Rankine cycles for electricity generation from low–medium-temperature heat. This work addresses the importance of holistic approaches by proposing a methodology for simultaneous consideration of heat, mass, and power in industrial processes. The methodology is applied to a kraft pulp mill. In doing so, freshwater consumption is reduced by more than 60%, while net power output is increased by a factor of up to six (from 3.2 MW to between 10–26 MW). The results show that interactions among these elements are complex and therefore underline the necessity of such comprehensive methods to explore their optimal integration with industrial processes. The potential applications of this work are vast, extending from total site resource integration to addressing synergies in the context of industrial symbiosis.

Purpose This paper studies a Swedish municipality that wants to go beyond its own operations, involving the local industry in saving energy to improve the environment. The paper aims to analyse the experiences and practical implications of using policy networks for implementing energy-efficiency measures in private industrial companies. Design/methodology/approach The researchers closely followed a Swedish municipality and its work to engage the local industry in energy-efficiency activities. Participatory observations of meetings and workshops and semi-structured interviews with involved actors were conducted. Findings The study examines a Swedish municipality that has started addressing energy efficiency in local businesses by creating a network involving 60 companies. This network was tested in relation to four hypotheses on how policy networks develop. The study finds that the network has too broad a problem definition, which does not help unify the involved actors. The companies’ involvement is based on passive participation in which they are receivers of information. The network has been unable to use a social control mechanism because there have been few company-to-company meetings. In conclusion, for a network to be an efficient policy tool, its structure is as important as the ideas for action and clear goals. Research limitations/implications This case study of one Swedish municipality allows for analytical but not statistical generalization. Originality/value The paper uniquely calls for reflection on whether municipalities and local authorities have enough competence to drive industrial energy efficiency.

Objective: Appalachian women continue to die younger than in other US regions. We performed a rapid scoping review to summarize women’s health research in Appalachia from 2000 to 2019, including health topics, study populations, theoretical frameworks, methods, and findings. Data Source: We searched bibliographic databases (eg, PubMed, PsycINFO, Google Scholar) for literature focusing on women’s health in Appalachia. Study Inclusion and Exclusion Criteria: Included articles were: (1) on women’s health in Appalachia; (2) published January 2000 to June 2019; (3) peer-reviewed; and (4) written in English. We excluded studies without reported data findings. Data Extraction: Two coders reviewed articles for descriptive information to create summary tables comparing variables of interest. Data Synthesis: Two coders co-reviewed a sub-sample to ensure consensus and refine data charting categories. We categorized major findings across the social-ecological framework. Results: A search of nearly 2 decades of literature revealed 81 articles, which primarily focused on cancer disparities (49.4%) and prenatal/pregnancy outcomes (23.5%). Many of these research studies took place in Central Appalachia (eg, 42.0% in Kentucky) with reproductive or middle-aged women (82.7%). Half of the studies employed quantitative methods, and half used qualitative methods, with few mixed method or community-engaged approaches (3.7%). Nearly half (40.7%) did not specify a theoretical framework. Findings included complex multi-level factors with few articles exploring the co-occurrence of factors across multiple levels. Conclusions: Future studies should: 1) systematically include Appalachian women at various life stages from under-represented sub-regions; 2) expand the use of rigorous methods and specified theoretical frameworks to account for complex interactions of social-ecological factors; and 3) build upon existing community assets to improve health in this vulnerable population.
