K. Kunita
Amino acids are produced 2.4 million ton per year all over the world. The Ajinomoto Group produces them mainly from sugars or starches through fermentation process and a large amount of organic by-products are also produced. The Ajinomoto Group has established system of so called "Bio-Cycle" to make use of these organic byproducts for sustainable amino acid production. These by-products are returned to farms mainly as fertilizer. This recycle system of fertilizer can save not only chemical fertilizer but also the energy and CO2 generation for chemical fertilizer production. Ajinomoto Group takes care of not only main products but also by-products with technical service, quality control to meet customer's satisfaction and environment preservation
全世界每年生产240万吨氨基酸。味之素集团主要以糖或淀粉为原料,通过发酵过程生产,同时还生产大量的有机副产品。味之素集团建立了所谓的“生物循环”系统,利用这些有机副产品进行可持续的氨基酸生产。这些副产品主要作为肥料返回农场。这种肥料循环系统不仅可以节省化肥,而且可以减少化肥生产的能源和二氧化碳的产生。味之素集团不仅对主产品,而且对副产品进行技术服务和质量控制,以满足客户的需求和环境保护

K. Hashimoto, T. Taura
For the formation of a sustainable society, focus is on "the possibility of reducing environmental load in the future ", which is inherent to artifacts, and propose a method by which concretely evaluate the possible future use of artifacts. Focus is on the general idea of "Latent Function " that is, the function of an artifact that becomes evident under different circumstance. In this research, focused on the prediction ability that people possess and devised a method of evaluating the future possibilities of artifacts by a questionnaire survey. Drink containers and chairs were the examples applied to verify the validity of this method
对于可持续社会的形成,重点关注人工制品所固有的“未来减少环境负荷的可能性”,并提出一种具体评价人工制品未来可能使用的方法。重点是“潜在功能”的一般概念,即在不同情况下变得明显的人工制品的功能。本研究针对人的预测能力,设计了一种评估人工制品未来可能性的问卷调查方法。以饮料容器和椅子为例,验证了该方法的有效性

Rapid Screening Method for Brominated Flame Retardants and Hexavalent Chromium by Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS) 飞行时间二次离子质谱法快速筛选溴化阻燃剂和六价铬
J. Naka, N. Hirano, H. Kurokawa, J. Kobayashi, Y. Kawashima
By Directive on RoHS, the use of six hazardous substances is restricted to new electrical and electronic equipment put on the market in Europe from 1 July 2006. The estimation of the type and the content of brominated flame retardants is necessary in plastics of the equipment and the parts. The new technique by using time-of-flight secondary ion mass spectrometry (TOF-SIMS) is proposed for rapid screening test of these substances. We named this technique one droplet extraction method. The sampling method of brominated flame retardants in plastic materials with toluene on silver substrate was investigated for analysis of trace organic compounds by TOF-SIMS. High impact polystyrene (PS) and polypropylene (PP) plates were prepared as evaluation samples containing decabromodiphenylether (DeBDE) of 0.01-10 wt%. Evaluation time that includes sample pretreatment time and measurement time was about 1 hour. The positive quasi-molecular ion (DeBDE+Ag)+ (DeBDE cationized with Ag) was suitable for estimation of DeBDE. It was proved that content and spectral intensity had the clear magnitude correlation within 0.01-10 wt% content of DeBDE. It was found that the quick decision of whether the brominated flame retardants in the plastics is the substance restricted or not by Directive on RoHS is possible by this method. We can screen the substances in wide range of content of 0.01-10 wt%. Also it was found that the quick decision of whether hexavalent chromium is present in metals is possible by an application of this method. It was confirmed that one droplet extraction method using TOF-SIMS is a very powerful technique for the rapid screening test of brominated flame retardants and Cr (VI). It can be expected that hazardous substance management that concerns Directive on RoHS becomes more reliable
根据RoHS指令,由2006年7月1日起,在欧洲投放市场的新电器及电子设备不得使用六种有害物质。对设备和部件塑料中溴化阻燃剂的种类和含量进行估算是必要的。提出了利用飞行时间二次离子质谱法(TOF-SIMS)对这些物质进行快速筛选的新技术。我们将此技术命名为“一滴萃取法”。用TOF-SIMS法研究了塑料材料中溴化阻燃剂在银基体上的取样方法,并对痕量有机化合物进行了分析。制备了高冲击聚苯乙烯(PS)和聚丙烯(PP)板作为评价样品,其中十溴二苯醚(DeBDE)含量为0.01-10 wt%。评估时间包括样品预处理时间和测量时间约为1小时。正准分子离子(DeBDE+Ag)+ (DeBDE被Ag阳离子化)适合用于DeBDE的估计。结果表明,在DeBDE含量0.01 ~ 10 wt%范围内,其含量与光谱强度具有明显的幅度相关性。结果表明,该方法可以快速判断塑料中溴化阻燃剂是否为RoHS指令限制物质。我们可以筛选含量在0.01- 10wt %范围内的物质。还发现,应用该方法可以快速确定金属中是否存在六价铬。验证了TOF-SIMS单滴萃取法是一种非常有效的溴化阻燃剂和Cr (VI)快速筛选试验技术,可以预见RoHS指令相关有害物质管理将变得更加可靠

DfR and DfD Applied to Electrical and Electronic Equipments Resulting Environmental Life Cycle Performance - A Case Study for Portugal DfR和DfD应用于电气和电子设备产生的环境生命周期性能-葡萄牙案例研究
E. Santos, P. Ferrão
The present study assesses on the role of ecodesign strategies to promote improvements in life cycle environmental performance of electrical and electronic equipment. Through the use of a simplified LCA (life cycle assessment) methodology, the life cycle environmental impacts of mobile phone equipments of successive product generations from one manufacturer were determined. LCA results have demonstrated that improvements in general product environmental performance can be obtained, although in some specific environmental impact categories, such improvements were limited. With the newly implemented WEEE management system in Portugal, the study on DfR (design for recycling) and DfD (design for disassembly) strategies has showed that DfR's potential for product environmental performance enhancement is limited, as recycling is still not very efficient and is dependent on multiple operations that have environmental impacts themselves. DfD, on the other hand, has proved to be an important strategy in reducing life cycle environmental impacts if it manages to promote product/component reuse
本研究评估了生态设计策略在促进电气和电子设备生命周期环境绩效改善中的作用。采用简化的LCA(生命周期评估)方法,确定了同一制造商连续几代手机设备的生命周期环境影响。LCA结果表明,一般产品的环境性能可以得到改善,尽管在某些特定的环境影响类别中,这种改善是有限的。随着葡萄牙新实施的WEEE管理系统,对DfR(回收设计)和DfD(拆卸设计)策略的研究表明,DfR对产品环境性能增强的潜力有限,因为回收仍然不是很有效,并且依赖于本身具有环境影响的多种操作。另一方面,如果DfD能够促进产品/组件的重用,那么它已被证明是减少生命周期环境影响的重要策略

Ecodesign Knowledge Transfer: How to take the Economical and Cultural Context of the Receiver into Consideration 生态设计知识转移:如何考虑接收者的经济和文化背景
J. Diehl
Since the beginning of the 90's Ecodesign Education and Knowledge has been built up based upon Ecodesign methodology developments and experiences in education and in practice in demonstration projects. During the end of the 90's first attempts took place to transfer the created Ecodesign education and knowledge from Europe to other parts of the world like Central & Latin America, India and Africa. Because of the differences in economical, social and cultural contexts the European Ecodesign approaches had to be adapted to the local situations in order to become effective and successful. Based upon these experiences we came to the conclusion that in order to transfer Ecodesign knowledge in an effective way to the local receivers (students, consultants, professionals), the specific background and characteristics of the receiver and the local context should be taken (more) into consideration
自90年代初以来,生态设计教育和知识已经建立在生态设计方法论的发展和教育经验以及示范项目的实践基础上。在90年代末,首次尝试将创建的生态设计教育和知识从欧洲转移到世界其他地区,如中美洲和拉丁美洲,印度和非洲。由于经济、社会和文化背景的差异,欧洲生态设计的方法必须适应当地的情况,才能变得有效和成功。基于这些经验,我们得出结论,为了有效地将生态设计知识传递给当地的接受者(学生、顾问、专业人士),接受者的具体背景和特征以及当地的环境应该考虑(更多)

A Conceptual Model for Sustainable Consumption 可持续消费的概念模型
Ming Xu, Tianzhu Zhang
To solve the more and more serious conflict between human society and environment, the traditional consumption style should be changed to a more sustainable style. The paper brings forward a conceptual model for sustainable consumption against the traditional style of consumption. The duration between natural material extracted from environment and emitted to environment again is divided into four phrases: extraction, manufacture, consumption, and recycle. The traditional style of consumption has another phrase that is waste. In the conceptual model we brought forward, there is no waste phrase which is replaced by a helical consumption style
为了解决人类社会与环境之间日益严重的矛盾,传统的消费方式应该转变为更可持续的消费方式。针对传统的消费模式,提出了可持续消费的概念模型。从环境中提取的天然物质到再次排放到环境中的过程分为四个阶段:提取、制造、消耗和回收。传统的消费方式还有另一个说法,那就是浪费。在我们提出的概念模型中,没有浪费的短语,取而代之的是螺旋式的消费方式

Grain-Size Dependence of Electrolytic Properties in 25 at.% Yttrium Doped Ceria Solid Electrolytes 25at电解性能的晶粒尺寸依赖性。%掺钇铈固体电解质
D. Ou, T. Mori, F. Ye, J. Zou, J. Drennan
The grain size dependence of electrolytic properties in 25 at.% yttrium doped ceria was investigated. The sintered bodies were prepared from fine Y0.25Ce0.75O1.875 powders synthesized by carbonate co-precipitation method. By using sintering temperature in range of 950deg-1400degC, the average grain size of electrolytes varied from 90 nm to 0.9 mum. The conductivity of samples with different grain size was determined by dc three-point measurements at 400degC-600degC. Then the activation energy was calculated from the data of electrical conductivity. Grain-size dependence was observed on the plots of conductivity vs. average grain size. As the grain size decreased from 0.9 mum to 0.3 mum, the conductivity decreased and the activation energy increased. This result was consistent with previous reports and could be explained by the space-charge-layer model. However, the conductivity increased while the grain size decreased from 0.3 mum to 90 nm. Correspondingly, the activation energy decreased. To clarify the mechanism of this phenomenon, the microstructure of samples was observed using TEM. Nano-sized domains inside the grains were observed on the high resolution images. Their size and amount were reduced as the grain size decreased. It is possible that the abnormal increase in conductivity at fine grain size (<0.3 mum) was partly contributed by the changes in nano-sized domains
晶粒尺寸对25at电解性能的影响。研究了%钇掺杂铈。采用碳酸盐共沉淀法合成Y0.25Ce0.75O1.875细粉制备烧结体。在950℃~ 1400℃的烧结温度范围内,电解液的平均晶粒尺寸为90 nm ~ 0.9 nm。采用直流三点测量法测定了不同晶粒尺寸样品在400℃-600℃的电导率。然后根据电导率数据计算活化能。在电导率与平均晶粒尺寸的关系图上观察到晶粒尺寸的依赖性。随着晶粒尺寸从0.9 μ m减小到0.3 μ m,电导率降低,活化能增大。这一结果与之前的报道一致,可以用空间电荷层模型来解释。晶粒尺寸从0.3 nm减小到90 nm,电导率增加。相应地,活化能减小。为了阐明这一现象的机理,利用透射电镜对样品的微观结构进行了观察。在高分辨率图像上观察到晶粒内部的纳米级畴。它们的尺寸和数量随着晶粒尺寸的减小而减小。细晶粒(<0.3 μ m)下电导率的异常增加可能部分归因于纳米结构域的变化

Low Environmentally Impact Recovery of Gold using Cyanide Producing Bacteria 利用产氰菌回收低环境影响金
Y. Kita, H. Nishikawa, M. Ike, T. Takemoto
In the electronic assembly, Au is frequently used for surface plating and a bonding wire material. To recover gold from waste electronics, the dissolution process using cyan is a popular method, however, the solution is highly toxic. Accordingly, the environmentally conscious substitute process is preferable. Chromobacterium violaceum having ability of cyanide formation and decomposition were used to dissolve Au and decompose cyanide after Au dissolution. In this study the effects of dissolved oxygen on Au dissolution was investigate as a factor of Au bioleaching and continuous and repeated batch cultures were performed for the continuous Au dissolution as a reproducing cyanide process. Dissolved oxygen concentration decreased by the bacterial respiration but the aeration could recover it and activate Au dissolution. By replacing the medium C.violaceum can produce cyanide repeatedly then 60% of Au was dissolved from Au powder after 300h immersion
在电子组装中,Au经常用于表面电镀和键合线材料。为了从废弃的电子产品中回收黄金,目前普遍采用的方法是用青色溶液溶解,但这种溶液毒性很大。因此,具有环保意识的替代过程是可取的。利用具有氰化物形成和分解能力的紫色杆菌溶解金,并在金溶解后分解氰化物。本研究以溶氧对金溶出的影响作为金生物浸出的一个因素进行了研究,并对连续溶出金进行了连续和重复的间歇培养,作为一种再生氰化工艺。溶解氧浓度因细菌呼吸作用而降低,但曝气可恢复溶解氧浓度并激活Au的溶解。通过更换培养基,紫孢杆菌可反复产生氰化物,浸金300h后金粉中溶解60%的金

By replacing the medium C.violaceum can produce cyanide repeatedly then 60% of Au was dissolved from Au powder after 300h immersion","PeriodicalId":383623,"journal":{"name":"2005 4th International Symposium on Environmentally Conscious Design and Inverse Manufacturing","volume":"416 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116137501","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}

The Impact of End-of-Life Vehicle Recycling Law on Automobile Recovery in Japan 日本报废汽车回收法对汽车回收的影响
Y. Ogushi, M. Kandlikar
The Japanese End-of-life Vehicle (ELV) Recycling Law came into force in January 2005 to cope with five million ELVs that are disposed every year. This study focuses on the impact of ELV Recycling Law on recovery of automobiles from the perspective of product life cycle. In response to the ELV Recycling Law, automobile manufacturers have focused on technological innovation that enhance the levels of material recycling and part reuse. Other life cycle outcomes, such as re manufacturing of vehicles, are not likely to emerge as a result of the enforcement of the law alone
日本《报废车辆回收法》于2005年1月生效,以处理每年丢弃的500万辆报废车辆。本研究主要从产品生命周期的角度研究电动汽车回收法对汽车回收的影响。为了应对《电动汽车回收法》,汽车制造商专注于提高材料回收和零件再利用水平的技术创新。其他生命周期的结果,如车辆的再制造,不太可能仅仅因为法律的执行而出现
