  • Spirits of ecological thinking

    This paper aims to prevent sustainability from being encapsulated within a prearranged framework. What was once a marginal concept has been captured by the dominant way of thinking within the corporate sector and education sustainability. This is based on a top down approach to management and hence sustainability where system and environment are identified as being separate. By tracing the ...

  • Deflating the Ecological Bubble

    Much wisdon is distributed throughout David Orr's provocative article, and I wish to comment on an important phenomenon that interacts with all of his laws. Like Orr, I'm concerned with the mixing zone between economic systems and ecological ...


  • Industrial ecology: an overview

    Industrial ecology is a young discipline that considers industrial and commercial enterprises as an ecosystem analogous to biological ecosystems. Its organising principle is that industrial systems should emulate the best features of biological ecosystems, thereby reducing energy and material consumption and waste generation. The benefits of such operations are reduced environmental damage and ...

  • The ecological filter system for treatment of decentralized wastewater

    A vertical flow constructed wetland was combined with a biological aerated filter to develop an ecological filter, and to obtain the optimal operating parameters: The hydraulic loading was 1.55 m3/(m2·d), carbon–nitrogen ratio was 10, and gas–water ratio was 6. The experimental results demonstrated considerable removal efficiency of chemical oxygen demand (COD), ammonia nitrogen ...

  • Ecological Risk Assessment

    In recent years, ecological risk assessment (ERA) has emerged as an important part of environmental protection programs. The following discussion provides a brief overview of ERA issues. What is ecological risk assessment? Ecological risk assessment is the practice of determining the nature and likelihood of effects of our actions on animals, plants, and the environment. ...

  • Exergy and industrial ecology: an application to an integrated energy system

    Exergy analysis can help integrate separate technologies following the principles of industrial ecology. An application of exergy analysis to calculate depletion numbers, which relate exergy destruction and total exergy use, is demonstrated for a gas turbine cycle combined with a hydrogen generation unit. The design includes a Solid Oxide Fuel Cell (SOFC) with internal natural gas reforming and a ...

  • Ecologically-based approaches to evaluate the sustainability of industrial systems

    Industrial ecology, promoted as a discipline of 'sustainability science', applies ecological concepts to industrial systems to improve their sustainability. Concepts such as diversity, food webs and nutrient recycling have been investigated for industrial systems. Complex systems theory may also prove to be an appropriate framework for industrial systems research. This framework can identify the ...

  • Industrial ecology as mediator and negotiator between ecology and industrial sustainability

    This article discusses hybrid theory development efforts within industrial ecology. The framework is Latour's (1988) Prince metaphor, which he expanded to describe machines and machinations, technology and society. Technology including industrial ecology is regarded here as mediator between nature and society. Aspects on standard ecology and principles for ecosystem thinking as background for our ...

  • Ecological Quality Ratios for Ecological Quality Assessment in Inland and Marine Waters

    The REBECCA project focuses on establishing quantitative relationships between physicochemical and hydromorphological pressures and biological indicators. One of the major applications of such relationships is to support the establishment of WFD compliant assessment and classification methods. All EU Member States are required to establish such methods for the different biological quality ...


  • The ecologically optimum application of nitrogen in wheat season of rice–wheat cropping system

    Because excessive application of N fertilizer for crop production leads to environmental pollution and low N utility efficiency, a better understanding of the effects of N application rates on crop yields and NO3–N leaching is required for developing optimum ecological N management that reduces NO3–N leaching while keeping crop yield. Field experiments at two sites in the Taihu region of China ...

  • Ecological user interface for emergency management decision support systems

    The user interface for decision support systems is normally structured for presenting relevant data for the skilled user in order to allow fast assessment and action of the hazardous situation, or for more complex situations to present the relevant rules and procedures to be followed in order to deal most efficiently with the situation. For situations not foreseen, however, no rules exist, and no ...

  • Commentary: regional environmental management systems: lessons and challenges for industrial ecology research

    Industrial ecology has made a major contribution to the tools of corporate environmental management over the last ten years. However, it is argued that most of that contribution has been at the level of products and individual firms. It is argued that if the concept of industrial ecology is to be developed in a way that attracts public policy attention then it will have to demonstrate greater ...

  • Developing predictive systems models to address complexity and relevance for ecological risk assessment

    Ecological risk assessments (ERAs) are not used as well as they could be in risk management. Part of the problem is that they often lack ecological relevance; that is, they fail to grasp necessary ecological complexities. Adding realism and complexity can be difficult and costly. We argue that predictive systems models (PSMs) can provide a way of capturing complexity and ecological relevance ...

  • An ecological engineering system model applied to the case of an integrated agro-industrial complex

    Intensive stock breeding namely swine, beef and dairy cattle and related activities are characterised by an enormous pollution potential. Without suitable treatment, this kind of waste with high levels of organic matter, nutrients, heavy metals and pathogenic microorganisms originates air, water, soil and food chain contamination. The removal or the reduction of the pollutant matter contained in ...

  • Technology, innovation and sustainability in sociocultural-ecological systems: a case in Mexico

    The use of technology when discussing sustainability has widely been praised. However, people's decision to employ technology is what will determine its role in addressing sustainability concerns or in acting as a negative force behind a development trend. This paper examines when technology is used to enhance a sustainable development, and enquiries into the role technology has had in an ...

  • Treatment of domestic wastewater using composite ecological system in Chinese rural area

    In this study, a newly developed contaminant removal system for domestic wastewater in rural area was used at the first time in Henan province, China. This composite ecological system (CES) consists of septic tank (ST), improved soil filter (ISF) and surface flow wetland (SFW). The performances of the system was to investigate the removal of biological oxygen demand (BOD), total nitrogen (TN), ...

  • Human consciousness as a base for sustainability in socio–economic–ecological systems

    Sustainability of socio–economic–ecological systems always implies a structural uncertainty coming mainly from the diversity of social values involved in the decision making processes required to manage the system. Such uncertainty cannot be reduced in any way, but needs to be managed if sustainability is to be pursued in its 'strong' meaning. This work proposes a methodology to manage structural ...

  • Ecological Conditioning and Optimisation of a Once-Through Cooling Water System

    For the coming decade, Dow Benelux will need antifouling treatment for its cooling water system. Hypochlorite dosing is still considered to be the best available technology (BAT). This is based on proven effectiveness, large experience, moderate costs, opportunities to further optimise the chlorination procedure, and by the fact that in earlier studies low-level ...

  • The clash between economics and ecology: frames and schemas

    The central problem of the clash between economics and ecology is a clash of what psychologists call 'frames'. Frames are the set of values, norms, assumptions and theories we use to understand, even describe a situation. It is now recognised that one of the most important sources of intractable conflicts is a difference in frames between the participants. Ecology is about systems, complex ...
