Misleading estimates of pollution prevention, performance, and cost of promising new environmentally conscious technologies might result when process design and LCA methods do not account data variability and uncertainty. This research attempts to develop novel assessment methodology for evaluation of risks and potential pay-offs of new technologies that avoid pollutant production; and demonstrate the methodology via case study of gasification technology by simultaneous characterizing data variability and uncertainty. Thus, assessments of advanced process technologies that are in early developmental stages should be based on proper understanding and representation of uncertainties.","PeriodicalId":217614,"journal":{"name":"2003 EcoDesign 3rd International Symposium on Environmentally Conscious Design and Inverse Manufacturing","volume":"10 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":"115601401","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 part agent is a network agent that follows via network counter-part in the real world. Its RFID or an electronic tag attached to the part is used as a key to the identification and temporal memory. The part agent gathers necessary information from the network and then makes a recommendation on maintenance of the part based on the gathered information and historical data of the part it contains. The proposed scheme and its requirements are described. An early result is shown of simplified simulation implemented to promote the re-use of parts. The remaining issues for realization of the system are discussed.","PeriodicalId":217614,"journal":{"name":"2003 EcoDesign 3rd International Symposium on Environmentally Conscious Design and Inverse Manufacturing","volume":"305 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":"121405518","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 bench scale reactor was used to evaluate the applicability of the struvite crystallization process to the effluent. The aeration of piggery wastewater leads to decreased phosphorous, ammonia, electrical conductivity and alkalinity due to the precipitation of Ca and Mg phosphate compounds. The degassing process also leads to the volatilization of ammonia and an increase in pH. Therefore, the feasibility of phosphate and ammonia recovery by struvite crystallization in a fluidized bed reactor from the effluent of a piggery waste water treatment facility was discussed. The phosphorous removal efficiency was measured in experiments with varying ammonia concentrations and NH/sub 4/-N/PO/sub 4/-P ratios. At an initial phosphorus concentration range under 40 mg/1 and NH/sub 4/-N/PO/sub 4/-P under 7, the removal efficiency reached about 80% and fine particles were decreased in the effluent.","PeriodicalId":217614,"journal":{"name":"2003 EcoDesign 3rd International Symposium on Environmentally Conscious Design and Inverse Manufacturing","volume":"11 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":"122525005","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 result of the prior evaluation should be used to increase the reusability, promote recycling, reduce the material usage, and reduce hazardous material usage. Since 1991, in an effort to promote the use of product assessment, the Clean Japan Center has done research on product assessment and, in addition, created and distributed general manuals. In Japanese large enterprises, the use of product assessment is being established; however, in the small and medium enterprise manufacturing industry, product assessment is still rarely used. In order to establish the use of product assessment in the small and medium enterprise manufacturing industry, a basic product assessment worksheet was developed. Using the basic worksheet, it is possible to quantitatively evaluate important factors for Environment Conscious Design such as: ease of disassembly, component sharing, reduce, reuse, recycle, and environmental information communication. By establishing the use of this basic worksheet, establishment of product assessment in the small and medium enterprise manufacturing industry is anticipated.","PeriodicalId":217614,"journal":{"name":"2003 EcoDesign 3rd International Symposium on Environmentally Conscious Design and Inverse Manufacturing","volume":"16 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":"115998851","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}

About communication on the Internet, suppliers have always to be aware of users. It is researched meta-information that means \"information about how to use information\". Moreover communication techniques on the Internet about \"environmental communication\", meta information is required too. In this study, suppliers and users in environmental information are divided into \"problem in the server (supplier) site side\" and \"problem in the user side\". Subsequently, the methods and results are analyzed and the solutions are conducted by viewpoints of meta information for environmental Web sites. As samples of author research, using the nonprofit organization Web site is exemplified. Furthermore, from the investigation for communication conditions within the consultancy turned to the solution of \"problem in the server (supplier) site side\", it was founded that specific tendency of environmental Web site rely on the first impression and the character quantity. Moreover, problems in the evaluated results by using Web usability evaluation concentrated on the evaluation item for visual recognition which is aware of environmental feeling. From the investigation trend of environmental Web site users to the solution of \"the problems in user side\", the main users are office workers who have \"purposes for studying as a beginner\". In addition, it is also suggested that they need ease of comprehensibility and investigation.

In this study, a simplified LCA (SLCA) and the environmentally responsible product assessment matrix (ERPA) methods were evaluated and the usefulness as a tool for identifying the environmental aspects of products in eco-design was examined. The case studies of the cellular phone and vacuum cleaner systems showed that the SLCA and the ERPA methods provided different information but they complement each other to some extent. While the SLCA generates more information on the inherent environmental characteristics of a product system so that it may be useful for new design/eco-innovation, the ERPA gives more information on the potentials for improvement in the product so that it can be effectively used in eco-redesign.","PeriodicalId":217614,"journal":{"name":"2003 EcoDesign 3rd International Symposium on Environmentally Conscious Design and Inverse Manufacturing","volume":"134 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":"131763240","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}

An effective way of reducing network CO/sub 2/ emission would be to design BSs that consume less power, thus reducing their emission at the use stage.
