  • The recycling cell formation problem means that disposal products are classified into recycling product families using group technology in their end-of-life phase. Disposal products have the uncertainties of product condition usage influences. Recycling cells are formed considering design, process and usage attributes. In this paper, a new approach for the design of cellular recycling system is proposed, which deals with the recycling cell formation and assignment of identical products concurrently. Fuzzy ART neural networks are applied to describe the condition of disposal product with the membership functions and to make recycling cell formation. The approach leads to cluster materials, components, and subassemblies for reuse or recycling and can evaluate the value at each cell of disposal products. Disposal refrigerators are shown as an example.

  • Today the tastes of consumers change rapidly and the kinds of the products become diverse. There- fore the product life cycle becomes shorter and shorter. Moreover the save of resources and the recycling for the environmental preservation are the essential theme. On this the necessary information for the product development increases enormously. For the right use of the information the design process should be supported by the proper design tool. For this the 'design catalogue system for recycling' is suggested here. This system consists of four parts. that is, 'the existing automobile system database', 'welting principle database', 'Assessment system of the ease of disassembly' and 'one's own product development ratabase'. By the use of this system the product development period could be reduced about 30% drastically.

  • In order to care about preserving the environment for future generations, each country has been required to make the laws of the environment. So car manufacturers must design, manufacture and sell cars and trucks that meet customer's need and must do this while meeting the needs of the environment. In this research we have developed product structure and configuration management system that treats electronic catalogs for recycling of automobile parts. This research focused on two system. One is XML-based electronic catalog that give the information about recycling of automobile parts. The other is product structure and configuration management system based on electronic catalog.

  • Recently, waste plastic recycling technology is transforming from Incineration system to pyrolysis gasification system which can derive the resources from environmental waste and charge no more environmental burden to nature. The present study was carried out to investigate the potential acute toxicity of derived product of pyrolysis gasifications system for recycling of waste plastic by a single oral dose in Sprague-Dawley Rats. In order to evaluate the hepatotoxic effects of derived product of pyrolysis gasification system, activities of serum transaminase were measured in rats. No related changes in survivals, clinical signs and the ratio of the liver to body weights of rats were monitored. The results showed that the single oral administration of material of pyrolysis system for recycling of waste plastic did not induce any toxic effect at orally single dose level of 0 and 100, 200, 400, 800mg/kg body weight in rats. We could not find out any significant tocxicity induced by single oral administrate of material of pyrolysis system for recycling of waste plastic.

  • The recycling cell formation problem means that disposal products are classified into recycling part families using group technology in their end of life phase. Disposal products have the uncertainties of product status by usage influences. Recycling cells are formed considering design, process and usage attributes. In this paper, a novel approach to the design of cellular recycling system is proposed, which deals with the recycling cell formation and assignment of identical products concurrently. Fuzzy clustering algorithm and Fuzzy-ART neural network are applied to describe the states of disposal product with the membership functions and to make recycling cell formation. This approach leads to recycling and reuse of the materials, components, and subassemblies and can evaluate the value at each cell of disposal products. Application examples are illustrated by disposal refrigerators, compared fuzzy clustering with Fuzzy-ART neural network performance in cell formation.

  • The objectives of this study were: (1) to identify differences in consumer attitudes and intentions to recycle fashion products using three types of recycling (including resale, reform, and donation), and (2) to examine the moderating effects of consumer prosocialness on the relationships between attitude and intention for each type of fashion product recycling. Men and women aged 20 years and over were recruited from a marketing research firm panel. Participants completed an online questionnaire incorporating measures for attitudes and intentions to resale, reform, and donate fashion products, prosocialness, frequency of purchasing fashion products, monthly amount of spending on fashion products, and demographic information. Data from 224 participants were analyzed using SPSS 25.0 and PROCESS macro. The results demonstrated that consumers had significantly different attitudes and intentions depending on type of fashion product recycling. Consumers had more positive attitudes toward donation compared to resale and reform types of recycling. Consumer intentions toward resale and donation were significantly higher than their intention to reform. Furthermore, this study confirmed that the attitude-intention gap in fashion product recycling can be explained by individual prosocialness. The moderating effects of prosocialness on the associations between attitude and intention to recycle were significant. The implications of increasing consumers' behavior intention to recycle fashion products was discussed and future research suggestions are provided.

  • The recycling cell formation problem means that disposal products are classified into recycling part families using group technology in their end-of-life phase. Disposal products have the uncertainties of product status by usage influences during product use phase, and recycling cells are formed design, process and usage attributes. In order to deal with the uncertainties, fuzzy set theory and fuzzy logic-based neural network model are applied to recycling cell formation problem for disposal products. Fuzzy C-mean algorithm and a heuristic approach based on fuzzy ART neural network is suggested. Especially, the modified Fuzzy ART neural network is shown that it has a good clustering results and gives an extension for systematically generating alternative solutions in the recycling cell formation problem. Disposal refrigerators are shown as examples.
