Mature economies which are driven mainly by small and medium sized enterprises (SMEs) are increasingly becoming dependent on material imports. Global material consumption is ever increasing, mainly driven by population increases. Decoupling of material consumption from economic growth is one of the greatest challenges of the 21st century. Within this paper available methods for the assessment of material efficiency on different economic scales are investigated and those detected that are particulary suitable for the use in SMEs. Recommendations for further improvements of the selected tools and an outlook concerning planned research activities in the field of material efficiency in enterprises, supply chains and circular economy aspects are given.
It has not yet been possible to achieve the desired aim of decoupling economic growth from global material demand. Small and medium sized enterprises (SMEs) represent the backbone of most industrialized economies. Although material efficiency is of vital importance for many SMEs, few of them actually treat it as their top priority. There is a cornucopia of tools and methods available which can be used for material efficiency purposes. These, however, have gained little ground in the SME-field. This work deals with the enabling factors for material efficiency improvements in manufacturing SMEs and projections towards aspects of supply chain and circular economy. A multi-disciplinary decoupling approach for manufacturing SMEs and an implementation roadmap for further practical development are proposed. The approach combines appropriate complexity of technology and socio-economic considerations. It enables a connection of existing methods and the implementation of established information technologies.
The paper analyses the importance of List's views on growth and integration from the perspective of modern approaches to economic growth and international economics. Furthermore, some ideas will be presented on how List's ideas could help to explain and understand current economic developments, such as the crisis of the European Union or the new form of isolationism of the United States of America.
Dieses Lehrbuch bietet eine verständliche Darstellung eines zentralen Teilgebiets der Ökonomik. Da Inhalt und Aussagewert der Mikroökonomik häufig dadurch unklar bleiben, dass die Studenten zu viel rechnen müssen und dabei nicht mehr genügend zum Denken kommen, wird die Algebra in nur sparsamer Dosierung eingesetzt. Dafür stellt das Buch die grundlegenden Fragestellungen und Modelle umso klarer und lesefreundlicher dar und unterstützt das Lernen mit zahlreichen Kontrollfragen.
Dass sich durch die vierte industrielle Revolution etwas ändern wird, steht außer Frage. Nur was genau? Fakt ist: Unternehmen der neuen und alten Ökonomie treffen aufeinander und müssen sich vernetzen. Isoliertes Handeln ist keine Option, Unternehmen müssen sich vernetzen. Die Effizienz der Produktionsprozesse kann durch den Einsatz von intelligenter Software und Sensortechnologie sowie die Vernetzung mit Zulieferern und Kunden gesteigert werden. Die Stärke der neuen Ökonomien wird auch in der "alten" Industrie einen Wandel der Arbeitswelt nach sich ziehen.
In order to decouple economic growth from global material consumption it is necessary to implement material efficiency strategies at the level of single enterprises and their supply chains, and to implement circular economy aspects. Manufacturing firms face multiple implementation challenges like cost limitations, competition, innovation and stakeholder pressure, and supplier and customer relationships, among others. Taking as an example a case of a medium-sized manufacturing company, opportunities to realise material efficiency improvements within the company borders - on the supply chain and by using circular economy measures - are assessed. Deterministic calculations and simulations, performed for the supply chain of this company, show that measures to increase material efficiency in the supply chain are important. However, they need to be complemented by efforts to return waste and used products to the economic cycle, which requires rethinking the traditional linear economic system.

. An extended evaluation of triggers and barriers to improve material efficiency in manufacturing companies, along the supply chain and concerning circular economy considerations is provided. This paper delivers an extended literature review, a critical discussion of the current situation and resulting challenges concerning material efficiency approaches in manufacturing supply chains. Finally, a conclusion and outlook on further research direction is given.
