Renewable Eco‐industrial Development

This article reviews the scope of the discipline of industrial ecology and, in the context of an urgent requirement for substantial and rapid change in the face of global sustainability challenges, argues that the discipline could embrace a more proactive, interventionist stance in the form of renewable eco‐industrial development. Existing eco‐industrialism is presented as flawed, with many cases premised on the use of nonrenewable resources. Renewable eco‐industrial development, while still nascent, has the potential both to resolve some sustainability challenges and to offer a new area of endeavor for industrial ecology, albeit one with its own unique difficulties, such as conflict with food production. Renewable eco‐industrial development is further argued to bring industrial ecology into a more socially critical stance as it concerns the future allocation of scarce resources.     

Reinterpreting Industrial Ecology

This article argues that industrial ecology has, to date, largely engaged with the ecological sciences at a superficial level, which has both attracted criticism of the field and limited its practical application for sustainable industrial development. On the basis of an analysis of the principle of succession, the role of waste, and the concept of diversity, the article highlights some of the key misconceptions that have resulted from the superficial engagement with the science of ecology. It is argued that industrial ecology should not be seen as a metaphor for industrial development; industrial ecology is the ecology of industry and should be studied as such. There are manifold general principles of ecology that underpin our understanding of the world; however, the physical manifestation and causal effects of these principles are particular to the system and its constituent elements under analysis. It is thus proposed that context‐specific observation and analysis of industry are required before theoretical and practical advancement of the field can be achieved.

The Relationship between Cleaner Production and Industrial Ecology

Industrial ecology is an emerging concept for the promotion of environmentally sound manufacturing and consumption. It aims to balance industrial development with the sustainable use of natural resources including energy, materials, and the capacity of the environment to assimilate wastes and render valuable services. The widespread adoption of industrial ecology can be furthered by a critical review of current preventive activities in industry. This article reviews the role that current preventive environmental activities-known as cleaner production-could play in the implementation of industrial ecology. The article focuses on whether cleaner production in its present form is sufficient, in terms of breadth of both industrial activities (sources) and environmental concerns (impacts addressed), for achieving industrial ecology's core objectives. It is concluded that current cleaner production practices are not sufficient for achieving the ultimate goals of industrial ecology. Nevertheless, cleaner production practices and methodologies may evolve into useful instruments for the implementation of industrial ecology.     

Mapping urban ecology education in the UK

Abstract

Urban ecology has matured as a field of investigation. This paper explores how well it has transitioned into the educational curricula of UK Higher Education Institutions (HEIs) by mapping the presence of urban ecological or environmental topics across undergraduate and postgraduate programmes. The prevalence of different topics, the level at which they are taught, and the disciplinary areas in which they are housed, are quantified. Urban ecological topics are found in programmes across 50 of 147 HEIs (34%), mainly taught in ancillary fashion to support wider subjects, though some specialist modules and even programmes do exist. Only one HEI incorporates a compulsory (core) dedicated urban ecology module at undergraduate level. Much urban ecology teaching takes place at advanced undergraduate and postgraduate levels. Applied topics are usually taught from an environmental science perspective, with common examples including urban hydrology, climate, and green infrastructure; probably to address global concerns about urban sustainability and resilience. In particular there is scope for greater incorporation of urban ecology topics and themes into biological and ecological programmes, and utilising cities as labs to explore these topics. The paper concludes with a discussion of some of these possibilities.

Introducing Templates for Sustainable Product Development

We have previously developed a method for sustainable product development (MSPD) based on backcasting from basic sustainability principles. The MSPD informs investigations of product‐related social and ecological sustainability aspects throughout a concurrent engineering product development process. We here introduce “templates” for sustainable product development (TSPDs) as a complement. The idea is to help product development teams to arrive faster and more easily at an overview of the major sustainability challenges and opportunities of a product category in the early development phases. The idea is also to inform creative communication between top management, stakeholders, and product developers. We present this approach through an evaluation case study, in which the TSPDs were used for a sustainability assessment of televisions (TVs) at the Matsushita Electric Group. We study whether the TSPD approach has the ability to (1) help shift focus from gradual improvements of a selection of aspects in relation to past environmental performance of a product category to a focus on the remaining gap to a sustainable situation, (2) facilitate consensus among organizational levels about major sustainability challenges and potential solutions for a product category, and (3) facilitate continued dialogue with external sustainability experts, identifying improvements that are relevant for strategic sustainable development. Our findings indicate that the TSPD approach captures overall sustainability aspects of the life cycle of product categories and that it has the above abilities.     

Industrial Symbiosis in Kalundborg, Denmark: A Quantitative Assessment of Economic and Environmental Aspects

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.     

Would Industrial Ecology Exist without Sustainability in the Background?

Industrial ecology rests historically—even in a short lifetime of 15 years or so—on the metaphorical power of natural ecosystems. Its evolution parallels the rise of concerns over unsustainability, that is, the threats to our world's ability to support human life the emergence of sustainability as a normative goal on a global scale. This article examines the relationships between industrial ecology and sustainability and argues that, in its historical relationship to classical ecology models, the field lacks power to address the full range of goals of sustainability, however defined. The classical ecosystem analogy omits aspects of human social and cultural life central to sustainability. But by moving beyond this model to more recent ecosystem models based on complexity theory, the field can expand its purview to address sustainability more broadly and powerfully. Complexity models of living systems can also ground alternative normative models for sustainability as an emergent property rather than the output of a mechanistic economic model for society's workings.     

Applying Industrial Symbiosis to Smallholder Farms

The study of industrial symbiosis (IS) has largely focused on the exchange of energy and materials among industrial processes in an effort to increase value and reduce environmental impact. Agricultural systems, particularly those located in developing countries, can benefit from the principles of IS. Relatively few studies have analyzed the potential benefits of integrated material and energy flows in smallholder farming, even though these systems are considered essential to the world's food supply and poverty reduction. Although the concepts can be applied to virtually any system, the study of industrial symbiosis has traditionally focused on industrialized systems in developed countries. The research presented here applies the principles of IS to smallholder farms using optimization techniques to maximize farm output while minimizing wastes. Our research links IS to the growing field of integrated farming research (IFR), which seeks to create new technologies that increase the production of farms by viewing the farm as a system. Bridging these fields enriches the potential for robust research outcomes in both areas and fills a current knowledge gap. IS benefits from exploring new applications and increasing its penetration into the developing world. IFR benefits from established IS tools to create alternate pathways for increased output based on symbiotic relationships. A small farming system in Liberia, West Africa, is used as a case study. System integration of individual unit processes shows increased productivity and decreased waste. The results of this analysis indicate that there are unrealized opportunities for IS in developing countries, and integration of IS techniques into smallholder farming operations has the potential for impacting sustainable development.

Integrating strategic environmental assessment and material flow accounting: a novel approach for moving towards sustainable urban futures

Purpose

The population living in urban areas of the world continues to grow rapidly. It is, thus, a great priority for the planning practice to embed sustainability concept in their urban development endeavors. Currently, development and expansion of urban systems stress the need to control consumption of resources, especially non-renewable ones. There is also a need to reduce related environmental impacts, while stimulating a sustainable pathway for the population and urban growth.

Methods

Strategic environmental assessment (SEA) is useful for policy design to build an integrated method for supporting the development of a sustainable society. It undertakes territorial assessments and describes urban flows and impacts related to them by using a variety of tools, including material flow accounting (MFA). This study employs MFA, as it fits well within the scope of SEA and supports the growing environmental attention in the urban metabolism approach. Although helpful, MFA has not been systematically applied in the urban development context; for this reason, this paper proposes the integration of SEA and MFA.

Results and discussion

Integration of SEA and MFA generates a new framework for sustainable development planning. The framework is structured in phases oriented to the continual improvement based on the Deming cycle (i.e., plan, do, check, act), a key management approach mainly used in businesses for improving the effectiveness of an organization. It can also be implemented at the urban system level. In order to maintain normative compliance, each process (urban planning, strategic environmental assessment with urban metabolism approach, participatory processes) is standardized in line with a common and mandatory approach. While the processes are integrated among them, highlighting the reciprocal contact points, the results are combined in a holistic perspective. The framework, hence, transforms the voluntary MFA tool into a mandatory process.

Conclusions

The proposed SEA-MFA framework has the potential to unify and standardize the processes of categorizing and quantifying data in order to improve the understanding of urban metabolic principles and scale effects. It also supports management and policy development and meets the requirements of different stakeholders. The framework, thus, generated a novel approach for sustainable urban development planning by providing solutions for specific policy problems and ensuring urban ecological balance and sustainable urban futures.

     

工业生态学的内涵与发展

作为一门发展不到20a的综合性交叉学科,工业生态学目前需要界定其学术范畴和理论基础.首先评述了工业生态学的4个主要领域:(1)社会代谢是工业生态学起源最早也是发展最为成熟的领域.它提供了宏观层次上观察和测量经济发展与物质流动关系的方法和工具,但需要进一步细化物质流动图景和加强流动机制的解释;(2)工业共生是工业生态学最具特征的领域.它实质上是人们出于观察视角的转变而对工业体系的重新认识.逻辑严谨且规则统一的解释框架有助于工业共生理论的发展和实践;(3)基础设施与产业相互选择且协同演进,二者共同构成了城市的物质基础,而城市又是更大范围内区域经济系统的子集.这一组工业生态学的研究对象需要处理产业全球化与社会和生态要素本土化的矛盾;(4)工业发展的可持续性是工业生态学关注的核心目标,而多样性和复杂性给其研究带来了很大的挑战.这提醒我们要避免陷入简单化、还原论或机械论的陷阱,多开展实证研究.最后,从本体论、方法论和隐喻3个标准给出了工业生态学的初步界定,并指出4个重要的努力方向.     

Environmental Security as a Case Study in Industrial Ecology

Environmental security is the integration of environmental and national security considerations at a national policy level. It is a relatively new and still somewhat contentious concept, although in some countries, such as the United States, it is increasingly being embedded in traditional security and foreign policy institutions. It is of interest to the industrial ecologist for several reasons. First, from the methodological perspective, environmental security issues are frequently complex, multidisciplinary, and multiscalar in both temporal and geographic dimensions. They are thus good opportunities to apply existing industrial ecology tools such as industrial metabolism stock and flow studies, as well as to support the development of new industrial ecology methods. Second, environmental security offers an important case study of an important fundamental industrial ecology dynamic: the movement of environment from overhead to strategic for society. This process occurs at many different scales, from implementation of design for environment methodologies within firms to integration of environmental and trade considerations in the World Trade Organization; and it is important for the industrial ecologist to begin to understand its underlying dynamics. Finally, national security is the quintessential raison d'etre of the national state. Accordingly, the integration of environmental considerations into national security policies and institutions, using industrial ecology methodologies and patterns of analysis, is a significant validation of the field.

Linking Industrial Ecology with Business Strategy: Creating Value for Green Product Design

As organizations practice environmental design, some discover green design positively impacts business performance. This article demonstrates how an organization can employ existing design methods and tools with the Kano technique to craft an environmental product design strategy that enhances its business strategy. These tools expand the toolbox of the industrial ecologist and enable the link between green design and business improvement. The Kano technique was developed in the 1980s to facilitate design of innovative products. We also introduce terminology and concepts such as “voices of the environment,”“environmental knowledge management,”“environmental profile,” and “environmental product attribute” in order to bridge the gap between industrial ecology and business concerns. To demonstrate how an organization can find the synergy between business value and environmental value, this article describes three activities and their corresponding tools and exhibits their use with industry examples. First, we present techniques by which designers can identify and prioritize customers and stakeholders who voice both environmental and business concerns. Second, we describe how voice‐of‐the‐customer translation techniques can be used to efficiently collect and translate data from these customers and stakeholders into critical environmental product and service attributes. Third, we discuss how the Kano technique can be used to connect green design to business strategy by making visible the variety of stakeholder and customer perceptions of these critical environmental attributes. Examples then demonstrate how those perceptions suggest appropriate approaches for integrating the critical environmental attributes into product and business strategy. Finally, we provide examples based on work done with General Electric Medical Systems (GEMS) to illustrate the design of products that improve environmental performance while adding greater perceived value for numerous customers along material‐flow value chains.     

From SLCA to Positive Sustainability Performance Measurement: A Two‐Tier Delphi Study

Life cycle sustainability assessment (LCSA) currently has a preoccupation with capturing and repairing negative dysfunctions and pathologies instead of fostering positive features that make a human life sustainable and worth living. With the intention to overcome this imbalance, this paper aims at transferring the shift to a positive sustainability performance measurement (PSPM) perspective in industrial ecology. We argue that positive performance is likely to develop from the lens of social life cycle assessment (SLCA), because sustainability is an anthropocentric concept that puts positive benefits to human well‐being (i.e., the social dimension of sustainability) at the center of the analysis. However, the field of SLCA is highly fragmented, without a coherent theoretical understanding and without a clear prioritization of problems and future research directions. Therefore, we engage in an extensive Delphi study with experts from academia and practice to foster a discussion of lessons learned from SLCA for PSPM. In this way, the paper contributes to a more coherent and deeper understanding of both connected fields. The results emphasize that SLCA has become a defensive risk management instrument against reputational damages, whereas PSPM offers the potential to proactively measure and manage positive contributions to sustainable development. We identify three main challenges (definitional, methodological, and managerial) and two main areas of benefits (organizational and societal) and use them to consolidate the debate on SLCA and PSPM and to provide a roadmap for future research.     

Assessment of sustainable livelihoods of different farmers in hilly red soil erosion areas of southern China

Livelihood vulnerability in environmentally fragile areas is emerging as a key issue due to its positive feedback to environmental degradation. Assessment of sustainable livelihoods is a crucial prerequisite for targeting interventions. However, aggregated analysis usually obtained ambiguous conclusions because they ignored the heterogeneity of rural households. Here, we evaluated the livelihood sustainability of different rural households by constructing an improved Livelihood Sustainability Index (LSI) in hilly red soil erosion areas of southern China. Changting County was selected as the study case by virtue of its unique representativeness in soil erosion and poverty. The results showed that livelihood sustainability among rural households was far from equivalent. Different from previous studies, higher nonfarm income share was not always consistent with higher extent of livelihood sustainability. Besides nonfarm employment, agricultural specialization could be another viable pathway to attain sustainable livelihoods. We also found that intergenerational sustainability was one primary cause for long-term livelihood differentiation of rural households. The poor education in rural areas would aggravate livelihood vulnerability of the poor and threaten the sustainable livelihoods of specialized agricultural households. Policy implications include further investment in rural infrastructure, irrigation and drainage, and stimulus for land transfer and concentration to facilitate agrarian specialization; enhancing investment in rural education to improve intergenerational sustainability; as well as targeting of the most vulnerable households, for example, promoting development of social insurance, social relief, and medical services for orphans and widows.
