This Special Volume of the Journal of Cleaner Production reports upon recent progress on regenerative and preventative eco-industrial development (EID), based upon comprehensive reviews, innovative policies, metrics and indicators, tools and methods and the implementation of sustainable production and consumption. The forty-one articles in this Special Volume show that tangible benefits can be achieved from initiatives performed at both local and national levels. The results and recommendations provide critical insights on how to promote innovative eco-industrial development within different contexts. An integrated framework for promoting regenerative and preventative EID is proposed so that powerful synergies for addressing both local environmental quality and global impacts and ways to track these improvements through the governance framework, can be created.

Improving efficiency and reducing energy intensity in these sectors are as important in the context of sustainability. Little to no studies have looked into the potential drivers to household energy consumption in a developing country such as the Philippines. Using a spatial decomposition analysis approach, various drivers to increasing household energy consumption in Metro Manila are estimated. Household size, income levels, energy intensity and energy use structure are considered in the study. The use of spatial decomposition techniques provides a new way to compare drivers between individual regions. The results are used to identify priority areas for electricity management and to draw insights for curbing household energy use. Policy implications are provided to conclude the study.

Many researchers investigated this trend, and in recent years, consumption-based accounting of energy use and emissions have gained attention. This study contributes to this literature by analyzing the effect of changing the accounting method for energy use on the resulting drivers identified from a decomposition analysis study. Specifically, the analysis is done on the increasing energy use in six ASEAN countries. The authors argue that since policy recommendations on energy and emissions are anchored significantly on these drivers, their sensitivity to the accounting approach used must be understood. The results show that the effect is not the same for all countries, and they can be grouped into 3 categories. The findings provide insights and raise questions regarding the sustainability of growing economies in the ASEAN region. To conclude, the results are reflected on from both a national and international perspective, and potential policy implications are discussed.

The emissions trading system is one of the primary instruments of the European region to achieve emissions reduction targets. As an alternative, some scholars investigate the potential role of electricity trading on emissions reduction as well. Acknowledging the fact that renewable sources and technical expertise may be concentrated in a few geographical areas, cross-border electricity trading provides a means to exploit these renewable resources, and therefore increase the potential for cleaner production of electricity. In the research presented in this paper, we decompose the effects of electricity trading to changes in CO2 emissions of the top 20 electricity trading countries in the European region. We compare the contributions of electricity imports and exports to changes in carbon emissions with those of traditional drivers, e.g. energy intensity, economic activity and population growth. A novel identity function was formulated in this paper to include the effects of electricity imports and exports in the decomposition analysis, using the logarithmic mean divisia index. Our results show that the European region offset approximately 10.3 MtCO2 from 1990 to 2014 due to electricity trading. This is because of large clean energy exports from France, Sweden and Switzerland. However, some countries have been adversely affected by electricity exporting, significantly increasing their emissions. In some countries, the increases in carbon emissions due to electricity exporting even outweighed increases due

Economic growth generates negative environmental and social impacts (TBL aspects); however, only a few studies have discussed the opportunities and threats in balancing TBL aspects. To fill this knowledge gap, this study addresses the opportunities and threats presented by the PSR. Nevertheless, information on the PSR is spread across diverse databases and is incomplete. This study utilizes a data-driven approach to handle these diverse databases and incomplete information and thereby to provide visual two- and three-dimensional impact analyses of opportunities and threats. This study contributes to the literature by (1) bridging TBL aspects of the PSR, (2) using a proposed hybrid method to address the aspect-balancing problem, and (3) providing insights on the opportunities and threats of the PSR. The results reveal negative effects of the PSR in terms of the balance between the economic and environmental aspects and that between the economic and social aspects. This study confirms that the scale and speed of development of the PSR pose a challenge to the environmental and social standards upheld by the surrounding countries and regions. Russia and the United Kingdom are ranked first and second in upholding these standards, while Germany, the Republic of Korea, the Netherlands and Norway strive to achieve a balance between the economic, social and environmental aspects.

Studies have attempted to consider knowledge management to promote corporate sustainability performance. However, the possible linkages and potential benefits for bridging knowledge management and corporate sustainability performance are still lacking in previous discussions. To address this gap, this study proposes a hybrid method that integrates a fuzzy synthetic method with an analytical network process to develop an interdependent hierarchical framework. The results indicate that the relation, operation and economy aspects must align with the priority goal of achieving better corporate sustainability performance. Improvements of these aspects rely on the knowledge management of developing rigid external collaboration, adopting information technology-supported processes and expanding capital for developing knowledge management. This study contributes to (1) bridging knowledge management and corporate sustainability performance; (2) providing a hybrid method to develop a hierarchical framework; and (3) giving specific directions for guiding improvements. Theoretical and managerial implications are discussed.

However, academia and industry have primarily focused on managing sustainable production and consumption and neglected resource management model. In addition, an appropriate tool must be developed for evaluating sustainable resource management model that considers the interrelationships and provides a guideline for performance improvement. This study proposes the application of an exploratory factor analysis to filter potential measures and the generation of a hybrid fuzzy synthetic method and decision-making and trial evaluation laboratory to assess the performance via a visual attribute map. The results demonstrate that social resources must prioritize and interact with environmental resources and indicate that economic resources are interrelated with social and environmental resources. Hence, this study enhances the understanding of causal sustainable resource management model by proposing a hybrid method for assessing performance via a hierarchical structure and offering a guideline to assist in performance improvements.

Advocates of such framework in planning of eco-industrial parks suggest that both economic and environmental gains can be attained by transforming the industrial production from a linear to a closed loop system. However, it is imperative first to understand and analyze systematically the barriers in implementing the concept of industrial ecology in industrial parks even at the early planning stage. This work thus proposes a problematique approach to understand and analyse such barriers toward a successful development of eco-industrial parks. A problematique is a term coined by Warfield referring to concepts and tools for a structural model of relationships among members of a set of problems. The problematique is shown to be effective in analyzing the str...

Cutoff walls are walls utilized when there is a need to restrict horizontal movement of liquids. Currently, the factors in designing cutoff walls are effective permeability, and relatively inexpensive materials in containing contaminants. It was suggested to provide a mix of 96% soil and 4% bentonite in the design of cutoff walls, but bentonite is relatively expensive, thus the viability of fly ash as a replacement for bentonite was considered. Soil mixtures were proposed and rigorous laboratory tests was performed to determine the individual properties. Tests such as specific gravity tests, Atterberg limit tests (liquid limit, plastic limit and plasticity index), emax and emin test/relative density tests, particle size analyses, microscopic characterizations, elemental composition tests and permeability tests were performed to garner data, and were utilized for the model. A linear optimization model was generated to achieve the least cost with the minimum required permeability. The minimum permeability requirement for the cutoff wall was achieved by providing various mixtures for soil-bentonite-fly ash.

Global CO2 emissions reached 32.4 Gt in 2014. Though the overall trend has been increasing, significant emissions reductions from Kyoto parties with targets have been achieved. The primary instrument for accomplishing this, has been the emissions trading system. Some scholars suggest electricity trading as an alternative. Electricity imports grew from 88 TWh to 510 TWh in OECD countries from 1974 to 2015. In non- OECD countries, the same was 238 TWh in 2014. Specifically, in the ASEAN, this is seen as a solution to looming energy security and pollution issues. Plenty of grid interconnections are being planned in the region. Through this study, learnings and policy implications from the EU are sought for the ASEAN region. Using decomposition analysis, the effects of imports and exports are compared against other traditional drivers such as population growth, econom...

The disruptive event affects the circularity in the supply chain due to numerous single-use-products in food, health, plastic industries. The unsustainable production and consumption is harmful for social, ecological, and economic systems. The industrial practices need a highly resilient network to have better visibility and agility to shift sourcing. Prior studies reveal the gap that CE needs the resilient systems. Still, there is a need to conceptualize and models resilience in CE studies using quantitative and qualitative approaches. Keywords: COVID-19 pandemic; circular economy; resilience in the supply chains. ABSTRAK Nota ini mendedahkan jurang lingkaran ekonomi (LE) dan daya tahan dalam literatur semasa pandemik COVID-19. Kejadian yang mengganggu ini mempengaruhi lingkaran dalam rantaian bekalan kerana banyak sekali produk sekali guna dalam industri makanan, kesiha...

This is somehow reflected in recent developments: from ridesharing, bike-sharing to car-sharing services in various countries. However, studies show that private vehicle ownership will continue to outgrow public transport use in developing countries up to the next decade as income levels rise. Recent vehicle ownership statistics in the Philippines support this. In this study, spatial decomposition methodology is used to compare the drivers to increasing traffic flow in different regions of the Philippines. The effects of potential explanatory factors including population, economic activity, travel intensity and modal structure to regional differences in traffic flow are estimated. Interestingly, results show that high traffic flow is only either driven by high economic activity, or high travel intensity ...

Trials for both antivirals and vaccines are in progress; candidates include existing repurposed drugs that were originally developed for other ailments. Once these products are shown to be effective, their production will need to be ramped up rapidly to keep pace with the growing demand as the pandemic progresses. It is highly likely that the drugs will be in short supply in the interim, which leaves policy makers and medical personnel with the difficult task of determining how to allocate them. Under such conditions, mathematical models can provide valuable decision support. In particular, useful models can be derived from process integration (PI) techniques that deal with tight resource constraints. In this paper, a linear programming (LP) model is developed to determine the allocation of COVID-19 drugs that minimizes patient morta...

Environmental labeling is a marketing technique used to inform consumers that a company has employed a process to protect the environment. However, uncertainty remains concerning how eco-labels influence consumers. Buying green products can elicit emotion in consumers. When consumers buy eco-products, they feel that they are helping save the environment. Products provide certain emotional benefits and therefore affect mood and behavior. This study aims to examine how consumers who differ in environmental attitudes respond to eco-labels. Aside from this, it wants to determine the intensity and type of emotions elicited by these kinds of products based on a certain set of pre-purchase emotions. These emotions are still unknown. Also, it proposes the Green Emotion Model (GEM) 2.0 that correlates environmental attitudes, visual...
