The volumes of Waste Electrical and Electronic Equipment (WEEE) generated in some African countries can be compared to those of some Eastern European countries, but many of them do not have any WEEE legislation and/or collection and treatment system in place besides voluntary initiatives and the informal sector. The volumes of EEE placed on the market are expected to grow by >7% in the coming years, with a focus on ICT and photovoltaics. The paper takes a look at the existing and planned legislation on WEEE in the African countries, showing the major components of the various WEEE systems and their differences.
一些非洲国家产生的废弃电气和电子设备的数量可以与一些东欧国家相比较,但其中许多国家除了自愿倡议和非正式部门之外,没有任何电气和电子设备立法和/或收集和处理系统。未来几年,市场上的电子电气设备的数量预计将增长100亿美元,重点是信息通信技术和光伏。本文考察了非洲国家现有的和计划中的报废电子电气设备立法,展示了各种报废电子电气设备系统的主要组成部分及其差异。

Based on the data of a recent study, the paper will show and analyse the factors that contribute to the fast improvement of energy efficiency of ICT end-user devices over the past years. The main purpose of the paper is to outline future developments and challenges with respect to the further improvement of energy efficiency in the field of end-user devices. In the paper the authors will argue that further improvement is strongly related to the user's capability to select the right product in terms of functional configuration for their individual use. Some possible solutions supporting the user will be discussed ranging from technical means such as advanced software solutions to the investigation of additional regulative requirements. Finally, the paper will investigate the economics of the remaining improvement potential. Hereby the authors address the critical issue of a technical “over-kill” in order to achieve further improvement of energy efficiency versus the resulting environmental impact over the whole product lifecycle.
基于最近一项研究的数据,本文将展示和分析在过去几年中促进ICT终端用户设备能源效率快速提高的因素。本文的主要目的是概述在终端用户设备领域进一步提高能源效率方面的未来发展和挑战。在本文中,作者将论证进一步的改进与用户根据其个人使用的功能配置选择正确产品的能力密切相关。将讨论支持用户的一些可能的解决方案,从先进的软件解决方案等技术手段到调查额外的监管要求。最后,本文将研究剩余改进潜力的经济学。因此,作者解决了技术“过度杀伤”的关键问题,以便在整个产品生命周期中实现能源效率的进一步提高,而不是由此产生的环境影响。

In recent years, numerous studies estimated the potential environmental benefits of ICT products and services. These studies usually extrapolate the results of small case studies to society-wide potentials. We analyse one of the most popular ICT services envisioned to induce such benefits, smart metering. Reviewing existing pilot studies, we establish an inverse correlation between the size of the case study and the resulted average energy reductions, casting a shadow over such extrapolations. We discuss several possible reasons for this inverse correlation, most importantly the representativeness of the case study. We also estimate the own life-cycle impact of smart meters, another topic often ignored in the literature. Building on these insights, we then present three own future scenarios for smart metering, which analyse the potential for energy and emission reductions in Sweden, the EU, the US and the world.
近年来,许多研究估计了信息通信技术产品和服务的潜在环境效益。这些研究通常将小案例研究的结果外推到全社会的潜力。我们分析了最受欢迎的信息通信技术服务之一,即智能电表。回顾现有的试点研究,我们在案例研究的规模和结果的平均能源减少之间建立了负相关关系,为这种推断投下了阴影。我们讨论了这种负相关的几个可能的原因,最重要的是案例研究的代表性。我们还估计了智能电表本身的生命周期影响,这是另一个在文献中经常被忽视的话题。在这些见解的基础上,我们提出了智能计量的三种未来情景,分析了瑞典、欧盟、美国和世界的能源和减排潜力。

The subject of this research is to find a process applicable to recycling FPC system adding extra functionality in the polymeric material without photo sensitive agent. We chose PBW (Proton Beam Writer) as an option. The potential impact by charge can modify electronic state and chemical bonding. Acceleration voltage and specific charge limit the depth of material modification. Proton is preferred to save acceleration voltage but the potential impact is low. We have investigated hydrogen molecular ions (H2+ and H3+) to compromise penetration depth and improve potential impact inside the material. These molecular ions are not easy to accelerate but have two or triple fold charges therefore they are especially suited to make big shallow structures. We can efficiently make the GTH (Groove and Thru-hole) structure combining them with Proton for deep structure.
本研究的主题是寻找一种适用于回收FPC系统的工艺,在聚合物材料中添加额外的功能而不使用光敏剂。我们选择了PBW(质子束写入器)作为选项。电荷的潜在冲击可以改变电子状态和化学键。加速电压和比电荷限制了材料改性的深度。质子是首选节省加速电压,但潜在的影响是低的。我们研究了氢分子离子(H2+和H3+)在降低渗透深度和改善材料内部潜在影响方面的作用。这些分子离子不容易加速,但有两倍或三倍的电荷,因此它们特别适合制造大的浅结构。我们可以有效地将它们与质子相结合来制作GTH(槽和通孔)结构。

Lessons learned from medical device refurbishment in the context of the RoHS Directive 在RoHS指令的背景下从医疗器械翻新中吸取的经验教训
Pub Date : 2016-09-01 DOI: 10.1109/egg.2016.7829869
Y. Baron
The medical sector has requested an exemption from the substance restrictions of Directive 2011/65/EU (RoHS 2) for refurbished devices. Through global refurbishment practices, many of the larger medical devices are collected, refurbished and then resold to new end-users. Such practices are particularly of interest at present, in light of their contribution to the circular economy. Refurbishment prolongs the service lives of products, giving added benefit to resources that have already been used, as well as to the end-users who purchase them.
医疗行业已要求豁免2011/65/EU指令(RoHS 2)对翻新设备的物质限制。通过全球翻新实践,许多较大的医疗设备被收集、翻新,然后转售给新的最终用户。鉴于这些做法对循环经济的贡献,它们目前尤其值得关注。翻新延长了产品的使用寿命,为已经使用的资源以及购买它们的最终用户带来了额外的好处。

The aim of the work was to ensure the after-market supply of an industrial robot handheld terminal independently from the original equipment manufacturer. Therefore, a remanufacturing process was developed. Additionally, an upcycling of the unit was realized by fixing the malfunctions of the original handheld terminal. Initially the malfunctions of the original handheld terminal were analyzed. Based on the results of this analysis a requirement specification of a remanufactured handheld terminal was developed. The necessary remanufacturing process consists out of six steps. Following this the original handheld terminal was dismantled and all components were classified. The wearing and defective components had to be reproduced. For this purpose, a redesign was used. For every reproduced part the most economic manufacturing process was chosen. The generated results were used to manufacture a prototype of the upcycled handheld terminal. Also the supply chain for the remanufactured and upcycled handheld terminal was elaborated.
这项工作的目的是确保独立于原始设备制造商的工业机器人手持终端的售后市场供应。因此,开发了一种再制造工艺。此外,通过修复原有手持终端的故障,实现了机组的升级改造。首先对原手持终端的故障进行了分析。在此基础上,提出了再制造手持终端的需求规范。必要的再制造过程包括六个步骤。随后,原始手持终端被拆除,所有部件被分类。磨损和有缺陷的部件必须重新生产。为此,使用了重新设计。对于每一个再生产部件,都选择了最经济的制造工艺。生成的结果被用于制造升级回收手持终端的原型。并对手持式终端再制造和升级再造的供应链进行了阐述。

Developing a reparability indicator for electronic products 电子产品可修复性指标的研究

Repair is a way to extend the life of a product. In a circular economy where resource loops are closed to a maximum extent, repair belongs to the ‘inner loops’. Repairing a product is a way to preserve value by slowing down the product's economic devaluation. The aim of the paper is the development of a reparability indicator: a measure to determine the ease of repair of a product. The indicator is developed for self-repair: repair done in a noncommercial context, by laypersons who lack access to a specialized workshop. Given the large diversity of products on the market, it was decided to focus on consumer electronic products. The paper consists of two parts. The first part is a review of the literature on (design for) reparability of electronic products, and on the development of repair indicators. A commonly used reparability indicator was empirically tested with 25 Dutch participants. This part concludes that the currently available guidelines, criteria and indicators provide a valuable starting point, but tend to lack structure, clarity and organization. The second part of the paper highlights the development of an improved reparability indicator. The first step for this was to ‘crowdsource’ repair criteria from the MOOC Circular Economy: an Introduction, which ran from October – December on the edX platform. One of the assignments in the MOOC was the development of repair criteria. Almost 2000 discrete entries were analysed, grouped and structured into 26 repair criteria. These have been tested for consistency with a group of 46 students of TU Delft in March 2016. The paper will present the results of this test as well as the improved reparability indicator.
维修是延长产品寿命的一种方式。在资源循环最大程度封闭的循环经济中,修复属于“内循环”。修理产品是一种通过减缓产品的经济贬值来保值的方法。本文的目的是开发一种可修复性指标:一种确定产品维修难易程度的措施。该指标是为自我修复而制定的:由无法进入专门车间的外行在非商业情况下进行的修复。鉴于市场上的产品种类繁多,我们决定把重点放在消费电子产品上。本文由两部分组成。第一部分是对电子产品可修复性设计的文献综述,以及修复指标的发展。对25名荷兰参与者进行了一项常用的可修复性指标的实证测试。本部分的结论是,目前可用的指导方针、标准和指标提供了一个有价值的起点,但往往缺乏结构、清晰度和组织性。论文的第二部分重点介绍了改进的可修复性指标的发展。第一步是“众包”MOOC《循环经济导论》中的修复标准,该课程于10月至12月在edX平台上进行。MOOC的任务之一是制定修复标准。近2000个离散条目被分析、分组并结构化为26个修复标准。2016年3月,代尔夫特理工大学的46名学生对这些方法进行了一致性测试。本文将介绍该试验的结果以及改进后的可修复性指标。

The research activities described in this manuscript were developed within HydroWEEE projects. These projects were funded by European Union in the ambit of 7 FP Work Program with the aim to develop innovative hydrometallurgical processes for the recovery of critical materials from waste electrical and electronic equipments as the fluorescent lamps and the cathode ray tubes. From recycling of them critical elements were recovered, in particular the rare earths. In the first phase of the project the hydrometallurgical processes for the recovery of yttrium was studied in laboratory and in the pilot plant. In the second phase the treatments were tested in the industrial scale, moreover the attention of researchers was focused on the implementation of the previous processes and made them more competitive increasing the fraction of recovered rare earths. Following the last experiences on laboratory scale for the recycling of lamps and cathode ray tubes were reported.

The advancing digitization of all areas of the economy and society is generating significantly increasing demand for processing power. More and more data centers of ever larger size are being built worldwide, and their electricity consumption is constantly on the rise. Forecasts project a significant increase in the global electricity consumption of data centers in the next five years. The presentation discusses the development of data centers' energy consumption and energy efficiency, using the example of Germany. A recent study by Borderstep and Fraunhofer IZM for the Federal Ministry for Economic Affairs and Energy shows that the electricity consumption of data centers in Germany grew by 15% to 12 billion kilowatt hours from 2010 to 2015. This was the case in spite of considerable efficiency gains in IT hardware and data center infrastructure. If the current trends in IT usage continue, German data centers' energy consumption will increase further and exceed 14 billion kWh in 2020. Reasons for this growth are in particular the increasing number of internet-enabled end-user devices and networked sensors. In addition, more and more processing is being shifted from end-user devices to data centers.
随着经济和社会各个领域的数字化不断推进,对处理能力的需求正在显著增加。在世界范围内,越来越多的数据中心规模越来越大,其用电量也在不断上升。据预测,未来五年全球数据中心的用电量将显著增加。本报告以德国为例,讨论了数据中心能耗和能源效率的发展。Borderstep和Fraunhofer IZM最近为联邦经济事务和能源部进行的一项研究表明,从2010年到2015年,德国数据中心的用电量增长了15%,达到120亿千瓦时。尽管在IT硬件和数据中心基础设施方面获得了相当大的效率提升,但情况仍然如此。如果目前的IT使用趋势继续下去,德国数据中心的能源消耗将进一步增加,到2020年将超过140亿千瓦时。这种增长的原因主要是支持互联网的终端用户设备和联网传感器数量的增加。此外,越来越多的处理正在从终端用户设备转移到数据中心。

More and more data centers of ever larger size are being built worldwide, and their electricity consumption is constantly on the rise. Forecasts project a significant increase in the global electricity consumption of data centers in the next five years. The presentation discusses the development of data centers' energy consumption and energy efficiency, using the example of Germany. A recent study by Borderstep and Fraunhofer IZM for the Federal Ministry for Economic Affairs and Energy shows that the electricity consumption of data centers in Germany grew by 15% to 12 billion kilowatt hours from 2010 to 2015. This was the case in spite of considerable efficiency gains in IT hardware and data center infrastructure. If the current trends in IT usage continue, German data centers' energy consumption will increase further and exceed 14 billion kWh in 2020. Reasons for this growth are in particular the increasing number of internet-enabled end-user devices and networked sensors. In addition, more and more processing is being shifted from end-user devices to data centers.","PeriodicalId":187870,"journal":{"name":"2016 Electronics Goes Green 2016+ (EGG)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114805881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2010 Brazil has instituted the national policy on solid waste (law 12.305/2010) that determines a set of principles and actions for the integrated management and environmentally appropriate of solid waste. To support WEEE recycling facilities to comply with national policy on solid waste, in 2013 the Information Technology Center Renato Archer (CTI), coordinated the creation of the Brazilian national standard “ABNT NBR 16156: Electrical and electronic equipment's waste - requirements for reverse manufacturing activity”. Furthermore, since 2015, supported by SIBRATEC, a Brazilian government program of technological extension, CTI has worked with small and medium sized enterprises of WEEE recycling, to help them suit the standard ABNT NBR 16156 requirements. This paper presents the technological efforts, of the Brazilian government, to support the WEEE recycling companies to comply the environmental sound practices, and thus, facilitate their participation in the reverse logistics system, regulated by the national policy on solid waste.
2010年,巴西制定了关于固体废物的国家政策(第12.305/2010号法律),为固体废物的综合管理和环境适宜性确定了一套原则和行动。为了支持报废电子电气设备回收设施符合国家固体废物政策,2013年,信息技术中心雷纳托·阿切尔(CTI)协调制定了巴西国家标准“ABNT NBR 16156:电气和电子设备的废物-逆向制造活动的要求”。此外,自2015年以来,在巴西政府技术推广计划SIBRATEC的支持下,CTI与中小型WEEE回收企业合作,帮助他们满足ABNT NBR 16156标准的要求。本文介绍了巴西政府在技术上的努力,以支持报废电子电气设备回收公司遵守环保实践,从而促进他们参与国家固体废物政策所规定的逆向物流系统。
