  • The efficiency and eco-efficiency of manufacturing

    In this paper, we review the efficiency of both manufacturing processes and systems over recent decades and compare nano-materials technologies in this context. To a first approximation, nano-materials processes appear to be about as efficient as semi-conductor processes. That is, their second law efficiencies are of the order 10−5, while conventional processes are of order 10−2. ...

  • Corporate sustainability: A guide to measuring and improving energy efficiencies

    As environmental scrutiny of global industries continues to grow, governments are seeking to impose energy efficiency targets on companies in order to comply with new directives. One solution is to encourage energy suppliers to become energy service companies, who work with customers to identify potential savings and share the benefits this delivers. For the global food processing industry, this ...

  • On eco-efficiency and sustainable development in Estonia

    The basic idea of sustainable development is a firm understanding that all resources, renewable as well as non-renewable, are limited. Human activities should not exceed the buffering capacity of the earth's ecosystems and the replenishment potential of material cycles. Use of non-renewable, mainly mineral, resources should be kept at the minimum possible level, postponing the depletion of ...

  • Eco-efficiency in the minerals and metals industry

    This paper explores the relationships between materials stewardship, eco-efficiency, and the product policies of governments. In doing so, a focus is maintained on the relevance of these industrial strategies and policies to the minerals and metals industry. Progress toward sustainable development requires a strong focus on accessing and harvesting natural resources with minimal social and ...

  • Work and eco-efficiency: opportunities and limitations

    In industrial ecology, the interaction of industrial and ecological systems has been approached mainly with concepts of metabolism, material flows and ecological metaphors. Less attention has been paid to the concept of work. In this article I study the contribution of eco-efficiency to social and ecological sustainability from the perspective of human work, work performed by technology and work ...

  • Do You Need a Microfiltration or Ultrafiltration Membrane System for Your Plant?

    Determining whether or not an industrial plant needs a microfiltration (MF) and/or ultrafiltration (UF) membrane system isn’t always as straightforward as it seems. While these systems are not essential for every industrial process, when thoughtfully implemented within an intake, process, or waste stream, they can go a long way in improving a facility’s efficiency and/or cutting ...

  • What 2017 holds for Energy from Waste in the UK

    The UK’s EfW industry has enjoyed two decades of stable investment under the public private partnership (PPP)/public finance initiative (PFI) regime. This has led to a reduction in the amount of biodegradable household waste sent to landfill via the construction of local authority-backed EfW plants and contributed to an increase in recycling rates by incorporating facilities that remove ...

  • Sustainable Biorefineries: An Important Research Topic

    In recent years, substantial steps into the transition towards a biobased economy have been taken in order to reduce the reliance on imported oil and the emission of greenhouse gases.  As far as Europe is concerned, Sweden, home to theEUBCE 2017 in Stockholm, has been very successful in decoupling GHG emissions from economic growth: from 2000 to 2012, ...

  • Optimizing Wind and Solar Power in Africa

    Editor's Note: The following is a news release authored by Julie Chao and issued by Lawrence Berkeley National Laboratory on April 5, 2017 To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment by the Department of Energy’s Lawrence ...

  • Eco-efficiency as a road-mapping instrument for WEEE implementation

    A comprehensive and quantitative eco-efficiency concept for end-of-life consumer electronics is developed at the TU Delft. It addresses the key question in setting up take-back systems for discarded consumer electronics: how much environmental improvement can be realised per amount of money invested? This paper highlights the latest results of applying the concept in practice on the ...
