Like many economic exchanges, industrial symbiosis (IS) is thought to be influenced by social relationships and shared norms among actors in a network. While many implicit references to social characteristics exist throughout the literature, there have been few explicit attempts to operationalize and measure the concepts. The “short mental distance,”“trust,”“openness,” and “communication” recorded among managers in Kalundborg, Denmark, set a precedent for examining and encouraging social interactions among key personnel in the dozens of eco‐industrial networks around the world. In this article we explore the relationships among various aspects of social embeddedness, social capital, and IS. We develop a conceptual framework and an approach using quantitative and qualitative methods to identify and measure these social characteristics, including social network structure, communication, and similarities in norms and conceptions of waste, and apply them in an industrial network in Nanjangud, South India. The findings suggest that there is a fairly high level of shared norms about dealing with waste—the “short mental distance”—in this network, but by‐product transactions are only weakly correlated with the structure and content of communication among managers. Replication of this approach can increase the understanding and comparability of the role of social characteristics in eco‐industrial activities around the world.  相似文献

By ‘working with the willing’, the National Industrial Symbiosis Programme (NISP) has successfully facilitated industrial symbiosis throughout the United Kingdom and, in the process, delivered significant economic and environmental benefits for both Programme members and the country as a whole. One of the keys to NISP's success is that, unlike failed attempts to plan and construct eco‐industrial systems from scratch, the Programme works largely with existing companies who have already settled in, developed, and successfully operate within a given locale. This article argues that existing and mature industrial systems provide the best prospects for identifying opportunities for, and ultimately facilitating, industrial symbiosis. Due to levels of diversification and operational fundamental niches that, in the fullness of time, develop within all industrial systems, industrially mature areas are deemed to be industrial symbiosis ‘conducive environments’. Building on the conservation biology concept of a habitat suitability index, the article presents a methodology for comparing a potential site for eco‐industrial development to a known baseline industrial ‘habitat’ already identified as being highly conducive to industrial symbiosis. The suitability index methodology is further developed and applied to a multi‐criteria evaluation geographic information system to produce a ‘habitat’ suitability map that allows practitioners to quickly identify potential industrial symbiosis hotspots (the methodology is illustrated for England). The article concludes by providing options for the development of symbiosis suitability indices and how they can be used to support the facilitation of industrial symbiosis and regional resource efficiency.  相似文献

Industrial symbiosis examines cooperative management of resource flows through networks of businesses known in the literature as industrial ecosystems. These industrial ecosystems have previously been portrayed as having characteristics of complex adaptive systems, but with insufficient attention to the internal and external phenomena describing their genesis. Drawing on biological, ecological, organizational, and systems theory, a discontinuous three‐stage model of industrial symbiosis is presented. The model proceeds from a random formative stage involving numerous actors engaging in material and energy exchanges, to conscious recognition and intentional pursuit of network benefits, to institutionalization of beliefs and norms enabling successful collaborative behavior. While there is much variation, with no single path to this outcome, the recognition of benefits is seen as an emergent property characteristic of these self‐organized systems that move beyond the initial stage.  相似文献

The identification of potential by‐product exchanges is important for fostering industrial symbiosis. To discover these potential exchanges, this article extends the analysis of local industrial symbiosis to a national scale. A waste input‐output table, which is a material flow accounting tool, was compiled and used as a database to examine the existing exchanges of by‐products. The supplies and demands of industrial wastes or by‐products were compared to highlight their potential use for promoting higher exchange flows. The analysis of the linkages indicated that the majority of each of the by‐products were reused by the few industries that had the technology and operational capacity for reuse. This finding is useful for determining which industries are good candidates for promoting further industrial symbiosis (IS). Based on a nation‐wide analysis that considered the industrial characteristics of Taiwan comprehensively, 23 types of major by‐products with greater reuse flows and 216 potential exchange patterns were identified between the industries. In addition, three types of eco‐industrial networks were characterized as follows according to their dominant types: (1) fossil fuel, metal, and mineral‐dominated; (2) agricultural and synthetic material‐dominated; and (3) information and communications technology (ICT) and chemical industry‐dominated eco‐industrial networks. This analysis highlights the resource exchange potentials and provides information to new firms for networking with existing businesses.  相似文献

In 2005, South Korea initiated the 15‐year National Eco‐Industrial Park Development Program in three stages to gradually transform aged industrial complexes into eco‐industrial parks (EIPs) by promoting industrial symbiosis (IS). Building upon the pilot experiences from the first 5 years, the second phase of the program focused on the scaling‐up of IS at a broader regional level. Key scaling‐up strategies included the expansion of target areas by connecting multiple industrial complexes, the standardization of processes and dissemination of learning, and the development of large‐scale projects that could contribute to the regional development. In this study, we examined the evolution of IS over the last 10 years between 2005 and 2014, primarily to understand the characteristics and impact of these scaling‐up strategies. Our findings showed that the scale of IS in the second phase had increased in various aspects in comparison to that in the first phase. The number of operating projects had increased from 52 to 159, the number of participating firms increased from 90 to 596, and the average distance of IS increased from 40 to 48 kilometers. The size of economic and environmental benefits also increased along with an increase in the private investment and government research funding. We further analyzed the role of the regional EIP centers as facilitators, how their activities influenced the scaling‐up of IS, and discussed the characteristics of the Korea's approach to IS.  相似文献

It has been long recognized in the conceptual literature that industrial symbiosis requires a perspective that focuses on long‐term evolution. This has not yet been matched by adopting an adequate process‐oriented research methodology. This article provides the underpinnings for such a methodology, presents a developed methodology, event sequence analysis, and shows its added value through a set of research questions and an empirical example. It shows how the process perspective leads to asking new research questions as well as the uncovering of new insights about the emergence, evolution, and dissolution of symbiotic relationships and the institutional capacity required to build such relationships.  相似文献

Models of eco‐industrial parks (EIPs) might help us transform our production systems by fostering the emergence of sustainable EIPs since such models have the potential to support the decision‐making processes of cooperative companies that participate and to decrease operational uncertainties. In this article, a conceptual framework for modeling the operation of EIPs is presented. The framework is underpinned by complex adaptive systems theory, industrial ecology, and an analysis of the experiences of existing EIPs. The proposed framework draws on the observed strengths of two types of industrial symbiosis models—planned eco‐industrial parks (PEIPs) and EIPs that developed through self‐organizing symbiosis (SOS)—as well as their observed weaknesses and the features of complex adaptive systems. From this analysis, five key properties to be modeled are deduced: functionality, reliability, life span, theoretical knowledge, and adaptability. It is proposed that the properties of functionality and theoretical knowledge are determined by the goals of the EIP and its member companies, while the property of adaptability is determined by the understanding that the companies in an EIP have of the environment surrounding the EIP, while the properties of reliability and life span are determined by the internal and external relationships of the companies that make up an EIP.  相似文献

By‐product synergy is a growing practice worldwide. It consists in the maximization of resources utilization with the replacement of raw materials by by‐products as inputs for industrial processes. In order to support decision making in such strategic projects, appropriate tools must be developed. This article presents the results of a research project, which includes the development of a multiobjective mathematical programming model for the optimization of by‐product flows, synergy configurations, and investment decisions in eco‐industrial networks. This model is evaluated using data related to the Kalundborg industrial symbiosis (IS) in order to illustrate its utilization, as well as to assess, in a retrospective manner, the behavior of the companies involved with respect to both economic and environmental benefits of synergies. The experiments also illustrate the influence of the municipality on synergy implementation and how a scenario‐based approach can be used to anticipate raw material price increase. The results are generally coherent with the actual timing of synergy initializations. Further, the considerable effect of water price on the length of investments’ payback period illustrates the impact of policies and regulations on IS.  相似文献

One assumption underlying the work on industrial symbiosis (IS) is that certain social conditions must be fulfilled in order for firms to develop symbiotic linkages. In this article we add depth to this insight by using institutional capacity as an underlying concept for these conditions, and we propose that such capacity influences IS by altering the opportunity set of actors. We then test the assumption on a dataset of 233 projects aiming to develop eco‐industrial parks. We find that the link between institutional capacity and the opportunities for symbiotic linkages perceived by actors is not always present and is more complicated than has been recognized thus far. We discuss potential alternative ways in which institutional capacity might influence IS and present ideas for future research to shed light on this important relationship.  相似文献

This article focuses on the effects of policy instruments for developing viable eco‐industrial parks (EIPs) in China. We analyzed the root of China's national EIP program and inventoried the general instruments available to local authorities to shape and promote eco‐industrial development. Empirical research conducted in Tianjin Economic‐technological Development Area and Dalian Development Area led to the activities and actions conducted by local authorities. A quantitative method, technique for order of preference by similarity to ideal solution, was adopted to reveal the effects of policy instruments for comparative analysis. We conclude that the planned EIP model is useful in the early stage of EIP development, and, subsequently, it should be combined with a facilitated model to achieve long‐term goals for eco‐transformation. To this end, the policy package of economic, regulatory, and voluntary instruments should be integrated and tailored in alignment with the local situation.  相似文献

As a subdiscipline of industrial ecology, industrial symbiosis is concerned with resource optimization among colocated companies. The industrial symbiosis complex in Kalundborg, Denmark is the seminal example of industrial symbiosis in the industrial ecology literature. In spite of this, there has been no in-depth quantitative analysis enabling more comprehensive understanding of economic and environmental performances connected to this case. In this article some of the central industrial symbiotic exchanges, involving water and steam, in Kalundborg are analyzed, using detailed economic and environmental data. It is found that both substantial and minor environmental benefits accrue from these industrial symbiosis exchanges and that economic motivation often is connected to upstream or downstream operational performance and not directly associated with the value of the exchanged byproduct or waste itself. It is concluded that industrial symbiosis, as viewed from a company perspective, has to be understood both in terms of individual economic and environmental performance, and as a more collective approach to industrial sustainability.  相似文献

I propose a T‐cell receptor (TcR)‐based mechanism by which immunity mediates both “genetic self” and “microbial self” thereby, connecting microbiome disease with autoimmunity. The hypothesis is based on simple principles. First, TcR are selected to avoid strong cross‐reactivity with “self,” resulting in selection for a TcR repertoire mimicking “genetic self.” Second, evolution has selected for a “microbial self” that mimics “genetic self” so as to share tolerance. In consequence, our TcR repertoire also mimics microbiome antigenicity, providing a novel mechanism for modulating tolerance to it. Also, the microbiome mimics the TcR repertoire, acting as a secondary immune system. I call this TcR‐microbiome mimicry “holoimmunity” to denote immune tolerance to the “holobiont self.” Logically, microbiome‐host mimicry means that autoimmunity directed at host antigens will also attack components of the microbiome, and conversely, an immunological attack on the microbiome may cross‐react with host antigens producing “holoautoimmunity.”

The Guitang Group (GG), which operates one of China's largest sugar refineries, has been developing and implementing an internal and external industrial symbiosis strategy for more than four decades. The GG first invested in developing its own collection of downstream companies to utilize nearly all byproducts of sugar production. This strategy has generated new revenues and reduced environmental emissions and disposal costs, while simultaneously improving the quality of sugar. Internally, the GG's complex consists of interlinked production of sugar, alcohol, cement, compound fertilizer, and paper and includes recycling and reuse. Externally, the GG has established a strong customer base as a result of its product quality, has worked to maintain and expand its supply base through technological and economic incentives to farmers (and even to competitors), and has had to react to a strong government presence that fundamentally affects its operations. Operations to date support some of the fundamental concepts of industrial symbiosis. Significant challenges exist, though, if the company is to continue to prosper in the volatile globalized sugar market.  相似文献

The realization of regional synergies in industrial areas with intensive minerals processing provides a significant avenue toward sustainable resource processing. This article provides an overview of past and current synergy developments in two of Australia's major heavy industrial regions, Kwinana (Western Australia) and Gladstone (Queensland), and includes a comparative review and assessment of the drivers, barriers, and trigger events for regional synergies initiatives in both areas. Kwinana and Gladstone compare favorably with well‐known international examples in terms of the current level and maturity of industry involvement and collaboration and the commitment to further explore regional resource synergies. Kwinana stands out with regard to the number, diversity, complexity, and maturity of existing synergies. Gladstone is remarkable with regard to unusually large geographic boundaries and high dominance of one industry sector. Many diverse regional synergy opportunities still appear to exist in both industrial regions (particularly in Kwinana), mostly in three broad areas: water, energy, and inorganic by‐product reuse. To enhance the further development of new regional synergies, the Centre for Sustainable Resource Processing (CSRP), a joint initiative of Australian minerals processing companies, research providers, and government agencies, has undertaken several collaborative projects. These include research to facilitate the process of identifying and evaluating potential synergy opportunities and assistance for the industries with feasibility studies and implementation of selected synergy projects in both regions. The article also reports on the progress to date from this CSRP research.  相似文献

A rationally designed “air chargeable” energy storage device is demonstrated, which can be effectively charged by harvesting pervasive energy from the ambient environment. For an “air chargeable” zinc‐ion capacitor system, the system simply consists of a flexible bifunctional “U” shaped electrode (with the functions of energy harvesting and storage), a zinc metal electrode in middle, and two different polyelectrolytes (polyacrylamide and sodium polyacrylate) sandwiched between the zinc metal and “U” shaped electrode. When the zinc‐ion capacitor is exhausted, it can be quickly charged to 88% within 10 min by simply opening the sealing tape and allowing the air diffuse in. The capacitor exhausting‐air charging processes are repeated 60 times and the whole system works well. When the external power supplier is available, both the zinc‐ion capacitor and “air charging” component can be fully recovered. A large capacity (≈1000 mAh) “air chargeable” zinc‐vanadium battery is also demonstrated. The zinc‐vanadium battery can be fully charged by air in 1 h. This work offers a usage scenario independent reliable self‐chargeable power supply system as a promising approach to solve the intermittent and unpredictable nature of currently developed self‐chargeable devices.  相似文献

In this article I unpack the labour of “networking” to understand the changes in sociality and worker identity that have occurred in the Australian professional managerial class workforce under post‐Fordism. Drawing on fieldwork undertaken at the interface of the pubic service and private consultancy firms in Canberra, I break from dominant readings of intimacy in post‐Fordism which preference either a downwards imposition of “ways of being” from capital to worker, or a reactive self‐regulation in line with objective external structures. Networking, I argue, is as much about being recognised as patron as it is about any tangible economic benefits. The intimate relations and self‐fashioning of networking constitute attempts to embody particular classed, sexualised, gendered fantasies of the figure of “the networker” in post‐Fordist Australian business culture. This interpretation does not necessitate overlooking the tangible results of networking, and I discuss too, how masculine fantasy structures the topography of workplaces.  相似文献

This article discusses whether “sustainability” has a physical meaning in applied thermodynamics. If it has, then it should be possible to derive general principles and rules for devising “sustainable systems.” If not, then other sides of the issue retain their relevance, but thermodynamic laws are not appropriate by themselves to decide whether a system or a scenario is sustainable. Here, we make use of a single axiom: that final consumption (material or immaterial) can be quantified solely in terms of equivalent primary exergy flows. On this basis, we develop a system theory that shows that if “simple” systems are based solely on the exploitation of fossil resources, they cannot be thermodynamically “sustainable.” But as renewable resources are brought into the picture and the system complexity grows, there are thresholds below or beyond which the system exhibits an ability to maintain itself (perhaps through fluctuations), in a self‐preserving (i.e., a sustainable) state. It appears that both complexity and the degree of nonlinearity of the transfer functions of the systems play a major role and—even for some of the simplest cases—lead to nontrivial solutions in phase space. Therefore, even if the examples presented in the article can be considered rather crude approximations to real, complex systems at best, the results show a trend that is worth further consideration.  相似文献

The transdiagnostic expression of psychotic experiences in common mental disorder (anxiety/depression/substance use disorder) is associated with a poorer prognosis, and a small minority of people may indeed develop a clinical picture that meets criteria for schizophrenia. However, it appears neither useful nor valid to observe early states of multidimensional psychopathology in young people through the “schizo”‐prism, and apply misleadingly simple, unnecessary and inefficient binary concepts of “risk” and “transition”. A review of the “ultra‐high risk” (UHR) or “clinical high risk” (CHR) literature indicates that UHR/CHR samples are highly heterogeneous and represent individuals diagnosed with common mental disorder (anxiety/depression/substance use disorder) and a degree of psychotic experiences. Epidemiological research has shown that psychotic experiences are a (possibly non‐causal) marker of the severity of multidimensional psychopathology, driving poor outcome, yet notions of “risk” and “transition” in UHR/CHR research are restrictively defined on the basis of positive psychotic phenomena alone, ignoring how baseline differences in multidimensional psychopathology may differentially impact course and outcome. The concepts of “risk” and “transition” in UHR/CHR research are measured on the same dimensional scale, yet are used to produce artificial diagnostic shifts. In fact, “transition” in UHR/CHR research occurs mainly as a function of variable sample enrichment strategies rather than the UHR/CHR “criteria” themselves. Furthermore, transition rates in UHR/CHR research are inflated as they do not exclude false positives associated with the natural fluctuation of dimensional expression of psychosis. Biological associations with “transition” thus likely represent false positive findings, as was the initial claim of strong effects of omega‐3 polyunsatured fatty acids in UHR samples. A large body of UHR/CHR intervention research has focused on the questionable outcome of “transition”, which shows lack of correlation with functional outcome. It may be more productive to consider the full range of person‐specific psychopathology in all young individuals who seek help for mental health problems, instead of “policing” youngsters for the transdiagnostic dimension of psychosis. Instead of the relatively inefficient medical high‐risk approach, a public health perspective, focusing on improved access to a low‐stigma, high‐hope, small scale and youth‐specific environment with acceptable language and interventions may represent a more useful and efficient strategy.  相似文献

This commentary responds to the previously published Journal of Industrial Ecology article “The Employment Footprints of Nations: Uncovering Master‐Servant Relationships” by Alsamawi and colleagues. Their article uses extended input‐output analysis to calculate employment and income footprints and, consequently, quantifies and provides an analysis of the average wages embodied in consumption of countries in comparison with the wages received by domestic workers. In effect, Alsamawi and colleagues show the extent of inequality in labor income, especially between developed and developing economies, traced throughout the global supply chains, but ignore the price differentials existing between countries in their discussion of the welfare implications of global trade on workers. This commentary contends the appropriateness of adjusting nominal compensation of workers to purchasing power parity (PPP) when undertaking global comparisons that pertain to well‐being and recalculates the employment footprints and income footprints of nations with PPP adjustment. The price adjustment in this work is intended to show a more accurate depiction of the disparity among workers of different nations when their labor incomes are deflated by the index price of consumption goods in their country. Using observations covering 189 countries and 14,839 sectors for the period 1990–2011, the results of the adjustment reveal that the ratio of domestic wages to foreign wages paid in support of a country's consumption (footprint wages) tends to be underestimated for labor‐exporting countries (developing economies with relatively cheaper consumption goods) and overestimated for labor‐importing countries (developed economies with more expensive consumption goods), thus demonstrating, generally, relatively less income inequality than previously exposed.  相似文献
