With increasing concerns about environmental issues that can result from apparel and textile disposal, the recycling methods for discarded fashion products have gained significant attention. As the influential drivers of consumer purchasing and consuming behaviors, fashion innovativeness and fashion involvement can play important roles in forming consumer attitudes toward apparel recycling. The purpose of this study was to (1) investigate consumer attitudes toward three different methods of apparel recycling including resale, reform, and donation, (2) examine the effects of fashion innovativeness and fashion involvement on consumers' apparel recycling attitudes, and (3) identify gender difference in the relationships among fashion innovativeness, fashion involvement, and recycling attitudes. Using a web-based survey, data were collected from 281 Korean consumers who were in their 20s and 30s. Overall, both male and female consumers revealed the most favorable attitudes toward apparel recycling through donation, followed by reform, and resale. The findings suggest that consumer traits, such as fashion innovativeness and fashion involvement, are important factors predicting male consumers' apparel recycling behaviors. Those male consumers who perceive fashion as important were more interested in apparel recycling than those males who put low importance on fashion. Male fashion innovators were less likely to recycle their unused and old apparel items. Further studies identifying antecedents of female consumers' attitudes toward apparel recycling are warranted.

The new recycling technology for aged Aluminum wires in overhead conductor have been carried out. We are attempting to develop remanufacturing method for them for more effective way of recycling in stead of its conventional remelting process. The weld of aged aluminum wires play a vital role in remanufacture process. The paper investigates the mechanical properties during cold welding process of aged Aluminum wire. The tensile tests and microscopic analysis results are discussed to underscore the hardening features of welded aluminum wire. Various graphs are presented accompanied by discussion about their relevance on the process.

In the present study, the thermodynamic evaluation of the sulfate-roasting process was conducted to extract vanadium from the Korean vanadium titano-magnetite ore. The leaching efficiency of vanadium and other impurities was analyzed for varying roasting temperatures and addition of Na₂SO₄. In the case of sulfate roasting, the roasting temperature was 200 ℃ higher than that previously observed Na₂CO₃ roasting. However, the higher leaching efficiency of vanadium and lower leaching efficiency of other impurities, such as aluminum and silicon, were observed. The high selectivity for the extraction of vanadium in sulfate roasting would result from the reaction mechanism between SO₂ gas and vanadium concentrate.

There are several kinds of batteries such as zinc-air battery, lithium battery, Manganese dry battery, silver oxide battery, sodium-sulphur battery, lead acid battery, metal hydride secondary battery, nickel-cadmium battery, lithium ion battery, alkaline battery, etc. These days it has been widely studied for the recycling technologies of the used battery from view points of economy and efficiency. In this paper, patents and published papers on the recycling technologies of the used battery were analyzed. The range of search was limited in the open patents of USA (US), European Union (EU), Japan (JP), Korea (KR) and SCI journal articles from 1972 to 2011. Patents and journal articles were collected using key-words searching and filtered by filtering criteria. The trends of the patents and journal articles were analyzed by the years, countries, companies, and technologies.

There is increasing interest to the development of environmental friendly products related global environment and health issue and it is very important technology for recycling contained hazardous substance that occur due to oxidation during used oils and fats of vegetable and animal to eco-friendly products. In this study, papers and patents for recycling technologies of used fat and vegetable oil as monomers were analyzed. The range of search was limited in the open patents of USA (US), European Union (EP), Japan (JP), Korea (KR) and SCI journals from 1976 to 2012. Patents and journals were collected using key-words searching and filtered by filtering criteria. The trends of the patents and journals were analyzed by the years, countries, companies, and technologies. Such pretreatment purification, polymerization for monomer, and polymer manufacturing technology were ahead of the United States.

In this study, the treatment flow of the recyclables(paper, plastic, metal, etc.) collected and separated from MSW was investigated throughout entire phase from separation and collection to final disposal. Based on the site survey, most recyclables came into six material recovery facilities were comparatively managed well. However, some of recyclables showed irrelatively transportation flow. Because the main income source of the recyclables transportation companies is profit margin between treatment and transportation cost based on economics only therefore, it occurs an unnecessary route and long distance transportation while going to final destination. This unreasonable system should be a serious problem relating establishment of the resource recycling system. As a result of this study, in order to establish the reasonably resource recycling system, recycling center including material recovery facility has to manage the recyclables generated in close range preferentially. Also integrated its treatment system over a wide area will need to be considered as a basic step for the reasonable reasonably resource recycling system.

It is generally well known that PCB (Printed Circuit Board) is an electric component assembled by various metals mixed with plastics and ceramics. Accordingly, it is very important to extract metallic components from used PCBs from the point of view of recycling of used resources as well as an environmental protection. In this paper, patents and paper on the recycling technologies of PCB were analyzed. The range of search was limited in the open patents of USA (US), European Union (EP), Japan (JP), Korea (KR) and SCI journals from 1980 to 2011. Patents and journals were collected using key-words searching and filtered by filtering criteria. The trends of the patents and journals was analyzed by the years, countries, companies, and technologies.

Chemical catalyst products are applied to various fields such as petrochemical process, air pollution prevention facility and automobile exhaust gas purifier. The domestic and overseas chemical catalyst market is increasing every year, and the amount of waste catalyst generated thereby is also increasing. Most of the used chemical catalyst products, such as desulfurized waste catalysts and automobile waste catalysts containing valuable metals are important recyclable resources from a substitute resource point of view. The recycling processes for recovering valuable metals have been commercialized through some urban mining companies, and SCR denitration catalysts have been recycled through some remanufacturing companies. In this paper, the amount of domestic production and recycling of major catalyst products have thus been investigated and analyzed so as to be used as basic data for establishing industrial support policy for recycling of used chemical catalyst products. Also tasks for promoting the recycling of used chemical catalyst products are suggested.

Recovery of indium from secondary sources have been attracting over years not only because of increasing demand together with development of flat panel display industry but also industrial criticality of indium. Applied technology to recover indium for recycling of end-of-life FPD devices can be broadly divided into three major steps, disassembly or dismantling, enrichment or upgrading, and refining or purification. In addition, advanced technology such as zone-refining can be employed for ultra-high purity products. In this mini-review, we present currently applied technologies for recovery of indium and the outlook for total recycling of FDP devices.
