Methane emissions from the organic fraction of waste in landfills contribute to global warming whereas for recycling, the global warming potential comes from the energy consumption of the recycling process. The whole life cycle of the two scenarios is considered, including transportation. The recycling option reduces the methane emissions from landfill due to diversion of waste. The study shows that this reduction more than offsets the increase due to energy consumption in the recycling process. Apart from the reduction in global warming potential, recycling also contributes to resource conservation. Thailand has a high potential for recycling since a large proportion of the waste currently going to the landfills is actually recyclable. Two case studies of ecodesign are also considered to highlight the increase in recyclability and the benefits thereof.","PeriodicalId":217614,"journal":{"name":"2003 EcoDesign 3rd International Symposium on Environmentally Conscious Design and Inverse Manufacturing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114746756","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}

A product which is made but not sold, and therefore not used by the consumer, is the most useless product there is. Therefore, methodical support is necessary to clearly identify the relevant customer requirements. One method capable of this is the Kano method, which is evaluated in this paper. For this, two surveys were carried out using a coffee maker as an example product: The first survey was a conventional Kano questionnaire and the second one was a modified and improved Kano questionnaire. To evaluate the results of both questionnaires, each was combined with a self-stated importance questionnaire. Finally, the results of the original and modified Kano method, as well as the self-stated importance method, were analyzed and compared to identify similarities and dissimilarities. It was found that the improved and modified questionnaire is a more effective and efficient way to identify even more polarized results.","PeriodicalId":217614,"journal":{"name":"2003 EcoDesign 3rd International Symposium on Environmentally Conscious Design and Inverse Manufacturing","volume":"425 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116230235","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}

First of all it is explained that the environmental analysis (Life Cycle thinking) to be made under the requirements of EuP best can be done on the basis of Environmental Benchmarking. Physical metrics is recommended to be the best instrument to do the analysis. Integration of EcoDesign into Product Creation Processes is a key condition for successful application of EuP principles. This process, including roadmapping and performance measurement. The opportunities and limitations of EuP (what can it deliver and what does it not deliver) has been discussed. The strength and weaknesses of the current draft EuP are analyzed based on the operational perspective sketched in this paper. Prospects for EuP in this respect are good, be it that still revisions of parts of the annexes are necessary to increase practicality and ecoefficiency.","PeriodicalId":217614,"journal":{"name":"2003 EcoDesign 3rd International Symposium on Environmentally Conscious Design and Inverse Manufacturing","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121718816","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 doing so, some of them face the problem that environmental soundness does not automatically imply market success. Therefore, methodical support is necessary which integrates environmental and market issues in a product. One method capable of this is an Eco quality function deployment (Eco-QFD). A major drawback of QFD is the high effort needed to carry it out, which is even higher by an Eco-QFD. Therefore, an integrated approach called EI2QFD, which reduces the effort of carrying out an Eco-QFD, is presented in this paper. Within EI2QFD the environmental Houses of Quality are nearly automatically derived from the results of a rough assessment with Eco-indicator 99. Only for the use phase, the QFD Team has to manually carry out some steps and check the results. Finally, to support the QFD-Team in the decision-making, the results are illustrated in a strategy portfolio. A prototype of EI2QFD is implemented in a Microsoft-Excel-based program using Visual Basic scripts.","PeriodicalId":217614,"journal":{"name":"2003 EcoDesign 3rd International Symposium on Environmentally Conscious Design and Inverse Manufacturing","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121069222","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}

Since existing fusing devices require a large heat capacity with a long warm-up time, they need to be kept at a constant temperature while printing is not conducted, resulting in large power consumption. On the other hand, using a thinner fuser roll with a small diameter for smaller heat capacity causes a roll deflection. With the deflection, it cannot form a uniform fusing nip, making it difficult to ensure fusing performance. In order to solve this problem, we have developed a Roll-in-Roll fuser for mid-to-high volume monochrome machines, and also a Free Belt Nip Fuser (FBNF) for color machines, as the fusing technology that can correct the roll deflection. Furthermore, with these two fusers, the warm-up time has been reduced substantially, reducing the energy consumption as a result.","PeriodicalId":217614,"journal":{"name":"2003 EcoDesign 3rd International Symposium on Environmentally Conscious Design and Inverse Manufacturing","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124879112","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 work developed the filtering method, which effectively removes the copper rich intermetallic phase by holding the solder with hypereutectic copper content just above the eutectic temperature of Sn-Cu. The filtering method developed by this study reduced copper content of Sn-1.5Cu to about 1%Cu after filtration.","PeriodicalId":217614,"journal":{"name":"2003 EcoDesign 3rd International Symposium on Environmentally Conscious Design and Inverse Manufacturing","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121669094","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}

Numerous studies have been conducted on environmental problems.

We consider this belief to be suspect and believe it is more effective to form a social system from the bottom up while retaining the current diversity of activities. In this paper, therefore, we discuss the nature of a cycle-oriented social system formed from the bottom up to achieve a sustainable society. By analysing its nature, we can identify the conditions under which the system will be sustainable. In order to conduct this analysis, we apply the abstract rewriting system on multisets (ARMS) technique.
