Recycling is one of the key strategies to secure the long-term supply of these metals. The dissipation of the metals related to the low concentrations in the products and to the configuration of the life cycle (short use time, insufficient collection, treatment focusing on the recovery of other materials) creates challenges to achieve efficient recycling. This article assesses the available data and sets priorities for further research aimed at developing solutions to improve the recycling of seven critical metals or metal families (antimony, cobalt, gallium, germanium, indium, REE and tantalum). Twenty-six metal applications were identified for those six metals and the REE family. The criteria used for the assessment are (i) the metal criticality related to strategic and economic issues; (ii) the share of the worldwide mine or refinery production going to EEE manufacturing; (iii) rough estimates of the concentration and the content of the metals in the products; (iv) the accuracy of the data already available; and (v) the occurrence of the application in specific WEEE groups. Eight applications were classified as relevant for further research, including the use of antimony as a flame retardant, gallium and germanium in integrated circuits, rare earths in phosphors and permanent magnets, cobalt in batteries, tantalum capacitors and indium as an indiumâtin-oxide transparent conductive layer in flat displays.BMBF, 033R087A, rÂł - Strategische Metalle, Verbundvorhaben: UPGRADE - Integrierte AnsĂ€tze zur RĂŒckgewinnung von Spurenmetallen und zur Verbesserung der Wertschöpfung aus Elektro- und ElektronikaltgerĂ€ten, TP1: Ăbergreifendes Stoffstrommanagement und Design fĂŒr Recyclin
Addressing sustainability and flexibility in manufacturing via smart modular machine tool frames to support sustainable value creation
Sustainability and flexibility are crucial aspects in todaysâ manufacturing processes. Within this study an innovative approach of modular machine tool frames (MMTF) equipped with micro system technology is presented that aims at enhancing flexibility of mutable production processes. This new approach extends the existing reconfigurable manufacturing systems (RMS). MMTF goes beyond the platform approach via minimizing the machine tool frame parts used for the building block system of manufacturing cells. The concept has been realized by integration of modularized microelectronics and actuators enabling for integrity and accuracy of the machine tool frame.
In this contribution, sustainable hotspots for the production of the MMTF are identified via a tiered life cycle sustainability assessment. From these findings, new approaches are derived that provide for a reasonable usage of mechanical and electronic components in MMTF for sustainable value creation
Forecasting drug utilization and expenditure in a metropolitan health region
<p>Abstract</p> <p>Background</p> <p>New pharmacological therapies are challenging the healthcare systems, and there is an increasing need to assess their therapeutic value in relation to existing alternatives as well as their potential budget impact. Consequently, new models to introduce drugs in healthcare are urgently needed. In the metropolitan health region of Stockholm, Sweden, a model has been developed including early warning (horizon scanning), forecasting of drug utilization and expenditure, critical drug evaluation as well as structured programs for the introduction and follow-up of new drugs. The aim of this paper is to present the forecasting model and the predicted growth in all therapeutic areas in 2010 and 2011.</p> <p>Methods</p> <p>Linear regression analysis was applied to aggregate sales data on hospital sales and dispensed drugs in ambulatory care, including both reimbursed expenditure and patient co-payment. The linear regression was applied on each pharmacological group based on four observations 2006-2009, and the crude predictions estimated for the coming two years 2010-2011. The crude predictions were then adjusted for factors likely to increase or decrease future utilization and expenditure, such as patent expiries, new drugs to be launched or new guidelines from national bodies or the regional Drug and Therapeutics Committee. The assessment included a close collaboration with clinical, clinical pharmacological and pharmaceutical experts from the regional Drug and Therapeutics Committee.</p> <p>Results</p> <p>The annual increase in total expenditure for prescription and hospital drugs was predicted to be 2.0% in 2010 and 4.0% in 2011. Expenditures will increase in most therapeutic areas, but most predominantly for antineoplastic and immune modulating agents as well as drugs for the nervous system, infectious diseases, and blood and blood-forming organs.</p> <p>Conclusions</p> <p>The utilisation and expenditure of drugs is difficult to forecast due to uncertainties about the rate of adoption of new medicines and various ongoing healthcare reforms and activities to improve the quality and efficiency of prescribing. Nevertheless, we believe our model will be valuable as an early warning system to start developing guidance for new drugs including systems to monitor their effectiveness, safety and cost-effectiveness in clinical practice.</p

Solutions for Sustainability-Driven Development of Manufacturing Technologies. Pt.II. Foreword
Sustainability imposes an unprecedented challenge on society and has become the driving force of an urgent search for innovative solutions in all branches of economy. Manufacturing plays a key role in many areas of human living, and it is both part of the problem and of the solution. This book offers an overview of the broad field of research on sustainability in manufacturing with a particular focus on manufacturing technology and management. It summarizes the current challenges, describes best in class methods for development of sustainable manufacturing solutions and offers implementation perspectives. This volume covers areas of research such as production processes, product development, business model and corporate development, macro economy and education. The target audience primarily comprises research experts and practitioners in the field of manufacturing, but the book may also be beneficial for graduate students
Eco-reliability - a combined approach to balance environment with reliability
Over the past years a new concept has evolved to combine eco-optimization with reliability aspects. As a short phrase we have coined the word eco-reliability, which we would like to explain and explore in the following paper

Circular added value: business model design in the circular economy
The current linear production and consumption structures, which build upon the intensive use of natural resources and cheap energy, are crucial drivers for the rapid economic development in the last sixty years. Biodiversity loss, climate change, conversion of the planet earth's surface and resource depletion force researchers, policy-makers, business representatives, and consumers to think about alternative economic approaches and lifestyles. The circular economy concept has recently attracted increased attention from academic, political, and economic institutions. The transformation to an economy characterized by cyclical and cascading usage of natural and physical capital requires disruptive and systemic innovations. On business level, integrated strategies consisting of sufficiency, consistency, and efficiency factors are needed to implement the idea of circularity in the architecture of enterprises. Business developers have to restructure value creation processes, dematerialize value propositions, rethink and demerge global supply chains or consider ecological and social aspects in their cost-benefit analyses. Currently, the most business modeling tools and methods do not consider characteristics that are crucial for designing circular business models. This study is built upon a five-step systematic literature review methodology, which focused on circular economy, conventional as well as circular business model literature. The insights gained from the extensive literature analyses were used to redefine the logic, composition, elements, and potential element attributes of the Business Model Canvas in the context of circular economy
A review of green electronics research trends
To set the stage for the conference it is of interest to take a look back in order to try a look forward at potential upcoming research trends. For this purpose research topics addressed in Electronics Goes Green conferences since 2000 are quantitatively investigated with a keyword density analysis. The focus is on analysing the development of research topic clusters over time providing an expert review of selected topics to fathom cause and effect. A topic cycle at conferences may end because the underlying problem has been solved, is regarded as unsolvable or has been superseded. This cannot be analysed from numerical records alone but needs access to experienced experts active during the time investigated. Note that this is an extension of a previous conference presentation without an accessible publication record
