On July 5, 1997, environmental Protection Administration of Taiwan publicized the recycling regulation of waste home appliances that include four items, namely, television, refrigerator, washing machine, and air conditioner. It is believed that this regulation pioneers the law enforcement of waste home appliances in the world. To comply with tile policy, several contemporary waste disposal plants specialized in waste home appliances were established according to a follow-up technical specification oil the waste treatment facilities and methodology. Therefore, the traditional dismantling facilities were substituted and waste collection routes were altered as well accordingly. This study investigates the collection and recycling costs of waste home appliances in accordance with these newly established routes and facilities, respectively. Cost survey was conducted among collectors and recycling plants of waste home appliances; consequently, tire collection and recycling costs were analyzed, correspondingly. Results show that the recycling costs of waste home appliances were much higher than that of other waste items. Since the market share of recycled materials is lacking, these waste recycling plants of home appliances can only survive under the subsidy of EPA in Taiwan. Due to some arduous problems, the subsidiary system has already caused serious financial unbalance for a foundation under EPA of Taiwan, which associated with waste recycling in Taiwan.

The purpose of this study is to investigate present situation of recovery and treatment of waste home appliances, and to supply basic data for active reuse and recycling of waste home appliances. Among waste home appliances, refrigerator comprise 30.7%, television 37.8%, washing machine 22.9% and air conditioner 0.3%. Local government collected 46.2% of waste home appliances, producer and agent collected 49.7%, recycling center 4.1%. Seventeen percentage of waste home appliances are reused, 65% are recycled, and 18% are landfilled or incinerated. To improve the recycling activity of waste of home appliances, it is important to establish private reuse and recycling organization. It is also necessary to improve waste deposit and refund system for efficient recycling by decent financial support. Extension of a term of usage is another method to minimize waste home appliances. Finally, intensive education for consumer is necessary for waste minimization. Some portion of recycling and treatment cost can be allocated to the local government and large private business can shred and recycle waste home appliances.

When the electrical appliances such as TVs and refrigerators become obsolete, they must be collected to the recycling centers to avoid environmental damages. The obsolete home appliances are first moved to the regional collection point; and then transported to one of the recycling centers. Each recycling center has a limited capacity; and some recycling centers can process only certain types of products. For given locations of the existing collection points and recycling centers, optimally assigning the obsolete home appliances of each type from each collection point to the recycling centers can significantly reduce the total transportation cost. We formulate this problem as an LP problem. We also present an approach to determine the locations of additional recycling centers in order to alleviate the over-utilization of the current recycling centers.

The waste home appliances including television sets, refrigerators, washing machines and air conditioners have increasingly received environmental concerns in Taiwan. In light of the enforcement of Waste Disposal Act (WDA), the Taiwan Environmental Protection Administration (EPA) has certified 60 recycling/storage facilities and given permission for qualified companies to build six treatment plants around the island. Now the recycling and well treatment home appliances are estimated to be 3,342,369 units until May 31, 2001. This paper describes the present status of waste home appliance recycle and its treatment in Taiwan. The principle guidelines and policies regarding recycling, resource recovery and environmental concerns are presented.

Waste electrical and electronic equipment(WEEE or E-waste) is one of the fastest growing waste stream in Korea. The proper management of such equipment has become of major concern for solid waste professionals because of the large growth of the waste stream and the presence of a myriad of toxic materials in it. In this paper, in order to evaluate the economical value of the recycling metallic materials from the E-waste, big size electrical home appliances, small size electrical home appliances, end of life hand phone and PCB(printed circuit board) were reviewed.

In order to review the recycling status of urban mine resources in Japan, metal consumption, metal recycling rate and metal recycling industry such as iron scrap, end of life vehiclcs(ELV), waste home appliances and spent IT equipments were surveyed. Japan took rank of top class in the world on the metal consumption and urban mine stock reserve. Metal recycling industries in Japan have been developed through excellent technologies for mineral processing and non-ferrous smelting. On the other hand, the technologies for recycling of rare metals are being developed now. Recycling rate of EL V, waste home appliances and personal computer are higher than the guidelines of the legislative standard.

Rapid increases of bulky home electric appliances such as televisions, refrigerators, washing machines, etc are about to create many problems in their waste management in Korea. This paper summarizes the present status of the discarded appliances treatment including the estimations of their quantity, constituent materials, and recyclings.

This study was performed by measuring the minimum ignition temperature of polyurethane form recovered from the recycling process of the end-of-life home appliances. The critical ignition temperature of polyurethane form was lower as the size of the sample vessel was increased, and that of polyurethane form using cyclopentane as the forming agent was relatively lower than the polyurethane form using CFC and the combustion of cyclopentane-polyurethane form occurred fiercely. It is considered that the recycling process of end-of-life home appliances using cyclopentane-polyurethane form as the insulator would require a special fire and dust explosion prevention measures since there exists a high potential hazard of fire and dust explosion during crushing and storage processes.

Although Japan, Korea, and Taiwan are all East Asian countries, there are marked differences in the recycling policies, motivations, and methodologies of each country. One reflection of differences is the approaches each country has taken toward the OECD proposal for Extended Producer Responsibility (EPR). I consider the relationship of local governments and producers for Japan, Korea, and Taiwan from the perspective of EPR. First, I provide an outline of the establishment of waste home appliances (WHA) recycling systems. And then, consider the responsibility of related subjects. Lastly, I prepare the differences of EFR concept of each country.

In this paper, we propose a small waste appliance collection system that can be used for efficient waste appliance collection, and implement an unmanned automatic small waste appliance collector system. First, we collected cases related to the collection of waste home appliances, compared and analyzed methods, and arranged the characteristics. We analyzed at the requirements for the collection and management system of waste appliances by dividing it into the aspect of the discharger and the recycling business company. The collection system consists of a client-server structure, which is a collector system and a collection management server. The unmanned automatic collector system is divided into a control unit and a machine/mechanical unit. We identified the functions that the collector system must perform and the hardware required to perform these functions. Based on this, the collector system was implemented as an embedded system. The hardware and software used in the implementation are described and the implementation results are described. The collection system developed in this paper will contribute to the development of urban mining industry by enabling the efficient collection of waste appliances.
