Expected Environmental Impacts of Pervasive Computing

ABSTRACT Pervasive Computing will bring about both additional loads on and benefits to the environment. The prevailing assessment of positive and negative effects will depend on how effectively energy and waste policy governs the development of ICT infrastructures and applications in the coming years. Although Pervasive Computing is not expected to change the impact of the technosphere on the environment radically, it may cause additional material and energy consumption due to the production and use of ICT as well as severe pollution risks that may come about as a result of the disposal of electronic waste. These first-order environmental impacts are to be set off against the second-order effects, such as higher eco-efficiency due to the possibility to optimize material and energy intensive processes or to replace them by pure signal processing (dematerialization). The potential environmental benefits from such second-order effects are considerable and can outweigh the first-order effects. But changes in demand for more efficient services (third-order effects) can counterbalance these savings. The experience gained thus far with ICT impacts has shown that such a rebound effect occurs in most cases of technological innovations.

Rebound effects of progress in information technology

Information technology (IT) is continuously making astounding progress in technical efficiency. The time, space, material and energy needed to provide a unit of IT service have decreased by three orders of magnitude since the first personal computer (PC) was sold. However, it seems difficult for society to translate IT’s efficiency progress into progress in terms of individual, organizational or socio-economic goals. In particular it seems to be difficult for individuals to work more efficiently, for organizations to be more productive and for the socio-economic system to be more sustainable by using increasingly efficient IT. This article provides empirical evidence and potential explanations for this problem. Many counterproductive effects of IT can be explained economically by rebound effects. Beyond that, we conclude that the technological determinism adopted by decision-makers is the main obstacle in translating IT’s progress into non-technical goals.ZusammenfassungDie Informationstechnologie macht laufend erstaunliche Fortschritte hinsichtlich technischer Effizienz. Zeit-, Raum-, Material- und Energieaufwand pro Einheit von IT-Dienstleistungen haben sich seit dem Verkauf des ersten PC um drei Größenordnungen verringert. Es scheint jedoch schwierig zu sein, die Entwicklung der IT-Effizienz in Fortschritte hinsichtlich individueller, organisatorischer oder sozioökonomischer Ziele umzumünzen. Insbesondere scheint es dem Einzelnen schwer zu fallen, die zunehmend effiziente IT zu nutzen, um selbst effizienter zu arbeiten; Organisationen scheinen durch effizientere IT nicht produktiver zu werden und sozioökonomische Systeme dem Ziel der Nachhaltigkeit nicht näher zu kommen. Dieser Artikel stellt empirische Ergebnisse und mögliche Erklärungen für dieses Problem zusammen. Viele kontraproduktive Effekte der IT können durch Rebound-Effekte ökonomisch erklärt werden. Darüber hinaus kommen wir zu der Schlussfolgerung, dass es hauptsächlich der technologische Determinismus von Entscheidungsträgern ist, der bisher die Nutzung des informationstechnischen Fortschritts für nicht-technische Ziele behindert.

Prospective Impacts of Electronic Textiles on Recycling and Disposal

Electronic textiles are a vanguard of an emerging generation of smart products. They consist of small electronic devices that are seamlessly embedded into clothing and technical textiles. E‐textiles provide enhanced functions in a variety of unobtrusive and convenient ways. Like many high‐tech products, e‐textiles may evolve to become a mass market in the future. In this case, large amounts of difficult‐to‐recycle products will be discarded. That can result in new waste problems. This article examines the possible end‐of‐life implications of textile‐integrated electronic waste. As a basis for assessment, the innovation trends of e‐textiles are reviewed, and an overview of their material composition is provided. Next, scenarios are developed to estimate the magnitude of future e‐textile waste streams. On that base, established disposal and recycling routes for e‐waste and old textiles are assessed in regard to their capabilities to process a blended feedstock of electronic and textile materials. The results suggest that recycling old e‐textiles will be difficult because valuable materials are dispersed in large amounts of heterogeneous textile waste. Moreover, the electronic components can act as contaminants in the recycling of textile materials. We recommend scrutinizing the innovation trend of technological convergence from the life cycle perspective. Technology developers and product designers should implement waste preventative measures at the early phases in the development process of the emerging technology.

Environmental and Health Implications of Nanotechnology—Have Innovators Learned the Lessons from Past Experiences?

ABSTRACT Nanotechnology (NT) is expected to bring about novel technological designs and materials resulting in a wide spectrum of applications. Experience gained from past innovations shows that new technologies are often accompanied by undesired side-effects. If such side-effects are neglected or underestimated, they may result in damage. In this article we examine whether innovators, the pioneers of technological advance in nanotechnology, are aware of the lessons that can be learned from adverse effects that have occurred in connection with several past innovations. Based on the results of a survey taken among innovators we discuss what consequences the innovators draw for the present innovation process and which priorities they set when dealing with environmental and health risks of nanotechnology. Results suggest that innovators may be not very sensitive to early scientific warnings regarding risks of nanotechnology. The innovators are confident that risks are assessable and manageable on a “business as usual” basis. They consider lacking public acceptance as a potential hurdle for innovation and many innovators are afraid of a backlash. Nevertheless, they seldom engage in risk communication or stakeholder dialogue. Picking up recommendations voiced by the innovators interviewed, we sketch some possible approaches as to how innovators could tackle the potential risks of nanotechnology in a proactive manner.

Critical materials: a reason for sustainable education of industrial designers and engineers

Developed economies have become highly dependent on a range of technology metals with names such as neodymium and terbium. Stakeholders have warned of the impending scarcity of these critical materials. Difficulties in materials supply can affect the high-tech industries as well as the success of sustainable innovation strategies that are based on sophisticated technology. Industrial designers and engineers should therefore increase their awareness of the limits in availability of critical materials. In this paper, it is argued that materials’ criticality can give a fresh impetus to the higher education of industrial design engineers. It is important to train future professionals to apply a systems perspective to the process of technology innovation, enabling them to thrive under circumstances of constrained material choices. The conclusions outline ideas on how to weave the topic into existing educational programmes of future technology developers.

Material Scarcity: A Reason for Responsibility in Technology Development and Product Design

There are warning signs for impending scarcity of certain technology metals that play a critical role in high-tech products. The scarce elements are indispensable for the design of modern technologies with superior performance. Material scarcity can restrain future innovations and presents therefore a serious risk that must be counteracted. However, the risk is often underrated in the pursuit of technological progress. Many innovators seem to be inattentive to the limitations in availability of critical resources and the possible implications thereof. The present shortages in industrial supply with technology metals may be interpreted as a wake-up call for technology developers to tackle the issue with due consideration. The article reviews the materials scarcity phenomenon from the viewpoint of sustainable development ethics. The following questions are discussed: ‘Should preventative actions be taken today in order to mitigate resource scarcity in future?’ and ‘Should technology developers feel responsible to do this?’ The discussion presents arguments for industrial designers and engineers to create a sense of responsibility for the proactive mitigation of material scarcity. Being protagonists of the innovation system, they have the opportunity to lead change towards resource-aware technology development. The paper concludes by outlining ideas on how they can pioneer sustainable management of critical materials.
