Used metallic can should be recycled from the point of view of environmental preservation and resource recycling. Metallic can is one of EPR items, and classified into steel can and aluminum can according to the can body material. In Korea about eighty percent of metallic cans are made of steel. In this article, production of cans and current status on domestic recycling of used metallic cans in recent years(2008-2012) were surveyed. Recycled ratio by weight of used steel and aluminum cans was about 80.8% and 81.8%, respectively in 2012. Totally it reached 81.8%.

Around the 1980s, with government's promotion and dissemination policies for FRP (Fiberglass Reinforced Plastics) of the government as a main material of fishing boats, approximately 97% of the entire fishing boats in Korea have utilized FRP until now. Nevertheless, diverse social and environmental issues have emerged due to the susceptibility to fire and the generation of substances detrimental to human health during the construction process of FRP fishing vessels. Especially, the high disposal cost and the limitation of recycling technology in the disposal process of FRP fishing boats have elicited attention to circular economy. This research intended to grasp the management status and problems of disposed FRP fishing boats in Korea, and to assess the level of competitive advantage of FRP fishing boats' recycling technologies of FRP fishing boats based on VRIO (Value, Rarity, Imitability, Organization) analysis through domestic and foreign management policies and related recycling examples. According to the survey of 161 respondents, including the industry, stakeholders and experts related to the collection, treatment and recycling of fisheries wastes, it was revealed that FRP fishing boats' recycling technologies of FRP fishing boats are at the level of 'unused competitive advantage' that satisfied the level of value, rarity and imitability, but not the level of organization.

Recently, plastic recycling has emerged as a social issue, and its importance is increasing. Therefore, this article reviewed the current status and the future directions of domestic plastic recycling. Plastic recycling is major economic and social problems not only in South Korea but also worldwide and is being treated as an important factor for protecting the environment and for sustainability in the next generation. In particular, China, which has been dealing with a large amount of plastic waste generated around the world, has banned importing plastic waste, therefore, other countries have faced the problem of recycling plastics in their countries. In South Korea, the landfill and incineration of the waste are becoming more difficult by the Framework Act on Resources Circulation, therefore, the recycling and reuse of plastics are a very important.

It is necessary that used metallic can should be recycled from the point of view of environmental preservation and resource recycling. Metallic can is classified into steel can and aluminum can according to the can body material. In Korea above eighty percent of cans are made from steel. In this article, production of cans and current status on the recycling of the used cans in recent years were surveyed. Recycled weight ratio of steel and aluminum can was about 75.6% and 74%, respectively in 2007. And totally it reached 75.3%.

Concrete produced from the construction wastes has been largely used as the recycled aggregate. These wastes, however, is mostly used as filling materials. For any recycled aggregate like waste concrete to be used as normal construction materials, it is necessary to actively find out the proper market places as much as possible with the improved quality. In this study, we have investigated the present status on the occurrence and treatment of both domestic and abroad construction wastes, and also the recycling status and related legislation with some inhibitory factors. Based on these investigations, we suggested some effective ways to increase the recycling of construction wastes.

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 use of water purifiers has been increasing every year due to increased drinking water safety concerns raised by the water pollution accidents occasionally reported. Currently, more than 10 million water purifiers have been distributed in Korea, and the estimation of the purifier sales reaches two million units per year. As a result, the number of used water purifier filters that must be replaced on a regular basis has gradually increased. However, regardless of the considerations for the capacity of used filters remaining, water purifier filters were replaced and collected at regular intervals. The high cost of disposal of the used filters by landfill or incineration were required. Thus, in this study, the current status and trends of recycling technologies for used water purifier filters were reviewed. It is noted that there was insufficient statistical data to understand the current status of the difference between the number of used water filters discarded and the number of those recycled. Most studies on the recycling of old water purifier filters have concentrated on pretreatment and cleaning methods for sediment filters and membrane filters, with the goal of extending the lifespan of used filters. Further, the study suggested future study directions on the recycling of used water purifier filters, which could be useful information on establishing environmental policy to promote the recycling of used filters.

In order to review the recycling status of urban mine resources in Taiwan, background and history of recycling industries, system of the recovery fund management committee(RFMC), copper recycling with non-ferrous metals, recycling of ELV(end of life vehicles) and recycling of EAF dust were surveyed. Taiwan is a leading country of the world in the metal consumption per capita. Therefore, a lot of waste metals were generated. In other words, urban mine resources are abundant in Taiwan and have some advantages in recycling. There are more than thou-sand recycling plants in Taiwan. Half of them are non-ferrous metal recyclers.

This study is conducted to find out the problem of the public food waste recycling facility and its improvement. By using an operation status analysis, an economic analysis was done to check up on its feasibility in comparison with an investment in the food waste recycling facility currently in use, thereby proposing the possible alternatives to prevent the national budgets form wasting with witless construction of the new facilities. As a result, it is considered necessary to come up with an effective plan for establishing the public resource facility, strengthen criteria for government subsidies being used up on the public resource facility, and enact an independent law of the food waste.
