    Get PDF
    E-waste is a priority waste stream as identified by the European Commission due to fast technological changes and eagerness of consumers to acquire new products. The value chain of the Waste on Electric and Electronic Equipment (WEEE) has to face several challenges: the EU directives requesting collection targets for 2019–2022, the costs of disassembly processes which is highly dependent on the applied technology and type of discarded device, and the sale of the obtained components and/or raw materials, with market prices varying according to uncontrolled variables at world level. This paper presents a human-robot collaboration for a recycling process where tasks are opportunistically assigned to either a human-being or a robot depending on the condition of the discarded electronic device. This solution presents some important advantages; i.e. tedious and dangerous tasks are assigned to robots whereas more value-added tasks are allocated to humans, thus preserving jobs and increasing job satisfaction. Furthermore, first results from a prototype show greater productivity and profitable projected investment

    Copyright © 2012 by Institution of Mechanical Engineers. This is the author's accepted manuscript. The final published article is available from the link below.Manufacturing firms are under many financial and competitive pressures which focus attention on the performance of their manufacturing processes. In this paper the opportunities for improving the environmental impact of products within the constraints of existing manufacturing infrastructure are examined. Approaches which support sustainability in two aspects are proposed, firstly, the provision of products to the users in ways which extend the product life and secondly, manufacturing approaches which reduce resource usage. This paper outlines three different sustainable development strategies for different product types and describes the cost implications for manufacturers across the life-cycle. The performance measures affected by these strategies are examined drawing on product development case studies from a number of high technology sectors to highlight the different approaches taken. The results are intended to aid manufacturers during the earliest stages of business planning to consider alternative product development approaches which are more sustainable

    Get PDF
    Additive manufacturing (AM) or three-dimensional (3D) printing has introduced a novel production method in design, manufacturing, and distribution to end-users. This technology has provided great freedom in design for creating complex components, highly customizable products, and efficient waste minimization. The last industrial revolution, namely industry 4.0, employs the integration of smart manufacturing systems and developed information technologies. Accordingly, AM plays a principal role in industry 4.0 thanks to numerous benefits, such as time and material saving, rapid prototyping, high efficiency, and decentralized production methods. This review paper is to organize a comprehensive study on AM technology and present the latest achievements and industrial applications. Besides that, this paper investigates the sustainability dimensions of the AM process and the added values in economic, social, and environment sections. Finally, the paper concludes by pointing out the future trend of AM in technology, applications, and materials aspects that have the potential to come up with new ideas for the future of AM explorations

    The new problems on global market bring a wind of changes in our lives, as well in technology, in environment protection, the future provoke us to find immediately solution and identify new sources for industry. The solution to this problem is the improvement of quality management of enterprises and also of products which must be designed taking into consideration the protection of environment. From this point of view we have to change the total quality management.Also the target of this research is to identify new solutions and recycle the possibilities of the materials.The intense search for solutions, the needs for a system of approach, the use of knowledge or models, can be used as a measure to reduce variations between different countries and develop a new system inside the universities which implemented a new eco age and which are preparing the new generation to redesign the mantra of this new eco-age and its green products.A solution to this challenge, and an explanation of applying a sustainable strategy under the principles of quality and continuous improvement in research work done in our universities will be presented in this article, as well as some solutions which guarantee the efficiency as a result to the new challenges in our market place and technological processquality, technological process

    Monitor Sustainable Municipalities Report 2019 Key topic Circular Economy. Bertelsmann Stiftung Study 4 November 2019

    At first sight, the concept for a recycling economy appears to be just the latest trend in the field of urban development, but in fact conversion to circular value creation also contains numerous oppor-tunities for the creation of long-term sustainable economic, social and environmental benefits for local communities. We have therefore chosen to look at this topic in this, our fourth, Monitor Report. Recycling Economy, Circular Value Creation and Cradle To Cradle are three concepts which – alt-hough each has a different main focus – basically all describe the same paradigm shift: away from a classic linear economy (“Take, Make, Use, Dispose”) towards a model based on restoration and regeneration. The recycling economy principle is actually anchored in the United Nations’ 17 Sustainable Devel-opment Goals, or SDGs. Goal 12 calls for sustainable consumption and sustainable production patterns. The recycling economy is also associated with a number of other sustainability goals, as it makes a significant contribution to their achievement. We are convinced that it is worth considering the applicability of the concept to local communities in Germany. What does transferring the recycling economy principle to local communities entail? How can towns be converted into “Recycling Cities”? Where are the obstacles and what potential is there? This Monitor Report is a first – it is the first bilingual version. With the kind permission of the Collab-orating Centre for Sustainable Consumption and Production (CSCP) in Wuppertal, we have issued their “Circular Economy Guidebook for Cities” in the original English with a German translation. We hope that, by looking at the bigger picture, we will also generate the impulse to consider how the topic can be adopted in (European) towns and cities, and what the resulting benefits could be. We are fully aware that a one-to-one transfer will not work. “One size fits all” does not apply to local communities. Although something that makes sense in Amsterdam, Copenhagen or Oslo may not necessarily work in towns, districts and local communities in Germany, it is definitely worth looking at how things are done in other countries. I would sincerely like to thank everyone who contributed to the creation of this Report, and especially the CSCP for its trust and invaluable cooperation. We hope you enjoy reading the Report, and look forward as always to your feedback and suggestions

    A Roadmap to Reduce U.S. Food Waste by 20 Percent

    Get PDF
    The magnitude of the food waste problem is difficult to comprehend. The U.S. spends $218 billion a year -- 1.3% of GDP -- growing, processing, transporting, and disposing of food that is never eaten. The causes of food waste are diverse, ranging from crops that never get harvested, to food left on overfilled plates, to near-expired milk and stale bread. ReFED is a coalition of over 30 business, nonprofit, foundation, and government leaders committed to building a different future, where food waste prevention, recovery, and recycling are recognized as an untapped opportunity to create jobs, alleviate hunger, and protect the environment -- all while stimulating a new multi-billion dollar market opportunity. ReFED developed A Roadmap to Reduce U.S. Food Waste as a data-driven guide to collectively take action to reduce food waste at scale nationwide.This Roadmap report is a guide and a call to action for us to work together to solve this problem. Businesses can save money for themselves and their customers. Policymakers can unleash a new wave of local job creation. Foundations can take a major step in addressing environmental issues and hunger. And innovators across all sectors can launch new products, services, and business models. There will be no losers, only winners, as food finds its way to its highest and best use

    A lean environmental benchmarking (LEB) method for the management of cutting tools

    Get PDF
    Manufacturing companies are striving hard to remain competitive hence, they rely on a number of resources to meet customers’ expectations, among which cutting tools are included. This paper addresses the problems faced in the management of cutting tools activities. Production managers have highlighted the lack of procedures containing metrics and targets that would show them whether their company is able to perform an efficient management, and if it is capable of supporting the deployment process. In this context, this paper presents a novel Lean Environmental Benchmarking (LEB) method for performing a diagnosis of practices and performances to support the implementation of a cutting tool management strategy and/or the effective management of these assets. Strategic, technical and logistical aspects are addressed, particularly, with regard to management focused on lean manufacturing and environmental aspects. Field studies were performed in nine Brazilian companies in the metal-mechanical sector to validate the LEB method proposed. The LEB method helped the participant organisations clarify the various activities that involved the management of their cutting tools, while the field studies indicated that all nine organisations had a great concern regarding the preservations of the environment, and also an effective utilisation of resources spent for machining components.N/
