It is thought that artifacts with abundant Latent Functions can be used continuously. However, the characteristic of artifacts with abundant Latent Functions have not been clarified. In this study, the discovery of Latent Function focusing on the relationship between the artifacts and decomposed components is investigated. The questionnaire and the interview to analyze the features of Latent Functions focused on the relationship between the artifacts and the decomposed components are conducted. In the result of analysis, more Latent Functions were discovered from the decomposed component (glass and wood, etc.) than from an artifact (table and wall clock, etc.). However, the proportion of Latent Functions discovered from the artifact including that component to the Latent Functions discovered from the decomposed components was very low

In cleaning processes of semiconductor manufacturing, a method called `RCA cleaning' is used for a long time. We suggest `functional water cleaning' as the first substituted method of RCA cleaning. Functional water for wet cleaning is water that specific gases are dissolved in, mainly hydrogenated water (H2-water) and ozonated water (O3-water). In this paper, we introduce cleaning effect, impact for cost reduction and ESH (Environment, Safety, Health) protection by using functional water.

The removal efficiency of formaldehyde, the ozone generation and also the conversion rate of formaldehyde to carbon dioxide in the corona discharge system was investigated. This system was composed of a needle discharge electrode and a conductive manganese oxide catalyst honeycomb. There was an optimal needle configuration for the maximum formaldehyde removal and the least ozone generation. Moreover, the conversion rate of the formaldehyde to the carbon dioxide at the optimal needle configuration increased gradually with the discharge power

A recycling plant is constructed for waste home appliances and operated from April 2000. A life cycle assessment (LCA) to compare recycling scenarios was conducted using the data from the operation. The results of the assessment show that it was effective from not only the reduction in the amount of the final disposal but also the point of the reduction in the environmental loads. Last EcoDesign2004, we reported the environmental load reduction effect in 2002. In this report, it evaluates by LCA again based on the data in 2004 that improves the recycling process based on the previous evaluation result, and it reports on the effect of the improvement

This paper describes an extension of a method for designing products with built-in disassembly means developed in previous work, as applied to a realistic example of a desktop computer assembly. Given component geometries and revenues, the method simultaneously determines, through an optimization process, the spatial configuration of component, locator and fasteners such that the product can be most economically disassembled via a domino-like "self-disassembly" process triggered by the removal of one or a few fasteners. A multi-objective genetic algorithm is utilized to search for Pareto-optimal designs in terms of four objectives: 1) satisfaction of the distance specification among components, 2) efficient use of locators on components, 3) profit of overall disassembly process, and 4) mass fraction of retrieved components. The method is applied to a simplified model of Power Mac G4 cubereg, and the results inspired a modification to the current design that can improve the ease of disassembly

The present legislation of the European Union as well as the environmental responsibility will increase the number of companies, who want to execute Life Cycle Assessments (LCAs) of their product in order to full fill future legislative requirements or to improve the environmental soundness of their products. The current instruments for LCAs are only isolated solutions and not integrated in the product development processes. The integration into the day to day development work can only be realised by using information and data which is already kept in the company. This article describes an approach for an LCA Tool integrated into the SAP E-Business Solutions

The possibility of hydrogen generation from the organic materials using supercritical water (SCW) was demonstrated in this paper. As for the hydrogen generation rate, i.e. the rate of gasification and the concentration of hydrogen in the decomposed gases the number of OH radical is one of the most important factors, where the decrease of the concentration of CO2 and increase of methane can be observed in case of using monohydric alcohol. From the practical view point, glycerin is one of the most suitable candidates for the hydrogen generation using the SCW. Glycerin can be obtained as by-product generated in the course of the bio-diesel (BDF) production using ester reaction of vegetable oils. If the utilization of BDF is spread, the rest material of glycerin can be used for the hydrogen generation using SCW and cost merit can also be expected

Having a life cycle perspective on products and services in the business strategy of functional sales is important as the strategy emerges and more and more companies see the benefits of controlling a larger share of the product value chain. It has become clear that a life cycle perspective needs to be addressed in such areas as manufacturing, use, maintenance and remanufacturing. This paper focuses on the product design issues for functional sales. Since the volumes of products being sold though functional sales and/or being remanufactured is increasing, these design issues need to be considered in a larger scale. In the paper, design improvements for functional sales of forklift trucks are described. Many of these improvements deal with the accessibility of parts and components during maintenance and remanufacturing operations. In general, the forklift trucks at the case study company (BT Industries) are easy to perform maintenance and remanufacturing on. However, there are improvements that could be done, and most of these seem fairly easy to perform. These results are in line with other product analyses previously conducted by the first author
