The status of waste generation and recycling in 32 countries in the European Union (EU), Japan, and the United States was investigated and summarized to encourage overseas market expansion for domestic urban mining industries. Among the 32 EU countries, Germany has the highest amount of material consumption and generates the largest quantity of waste. Minerals such as mine and soil wastes constitute the largest type of waste in the EU. With respect to waste treatment techniques, landfill and recycling are applied to 39% and 38% of the waste, respectively, implying the necessity to promote recycling. Japan's total waste generation declined recently to less than 400 million tons. The largest amount of waste is generated by the manufacturing industries. The proportion of total recycled waste is estimated to be slightly over 50%, but the proportions are greater than 90% for metal scrap and 60% for waste plastics. The amount of waste produced in the United States recently exceeded 265 million tons; 52.1% of the waste is landfilled, while only 25.1% is recycled. Therefore, the recycling industry has to be developed further.

These days many companies are trying to reduce, recycle and reuse their wastes. Even though many wastes can be recycled, those are incinerated or landfilled. To solve these problems, there are many projects to make efforts to recycle wastes in especially the industrial complexes. But, due to the absence of information about waste recycling, recyclable wastes are still incinerated or landfilled. Based on these research background, this study aims to suggest the evaluation methodology of the $CO_2$ emissions and cost reduced by circulating the industrial waste to resource. We evaluated the environmental and economic effect between companies which emit the plastic waste and organic solvent waste and use them as raw-materials in the off-line recycling information exchange network. The environmental and economic aspects were analyzed comparing waste recycling with waste incineration. By recycling the plastic waste as raw-materials, $CO_2$ emission were reduced 1,070 ton in 2009 and 1,234 ton in 2010 and 657.4 million won in 2009 and 755.0 million won in 2010 were reduced. In recycling the organic solvent waste, 7.3 ton-$CO_2$ in 2010 and 5.6 ton-$CO_2$ in 2011 were reduced and 15.9 million won in 2010 and 12.2 million won in 2011 were reduced.

Despite the continuous installation and regular inspection of waste treatment facilities, complaints about excessive incineration and illegal dumping stench continue to occur at on-site treatment facilities. In addition, field surveys were conducted on the waste treatment facilities currently in operation (6 type) to understand the waste treatment process for each field, to grasp the main operating factors applied to the inspection. In addition, we calculated the material·energy balance for each main process and confirmed the proper operation of the waste disposal facility. As a result of the site survey, in the case of heat treatment facilities such as incineration, cement kilns, and incineration heat recovery facilities, the main factors are maintenance of the temperature of the incinerator required for incineration and treatment of the generated air pollutants, and in the case of landfill facilities Retaining wall stability, closed landfill leachate and emission control emerged as major factors. In the case of sterilization and crushing facilities, the most important factor is whether or not sterilization is possible (apobacterium inspection).In the case of food distribution waste treatment facilities, retention time and odor control during fermentation (digestion, decomposed) are major factors. Calculation results of material balance and energy resin for each waste treatment facility In the case of incineration facilities, it was confirmed that the amount of flooring materials generated is about 14 % and the amount of scattering materials is about 3 % of the amount of waste input, and that the facility is being operated properly. In addition, among foodwaste facilities, in the case of an anaerobic digestion facility, the amount of biogas generated relative to the amount of inflow is about 17 %, and the biogas conversion efficiency is about 81 %, in the case of composting facility, about 11 % composting of the inflow waste was produced, and it was comfirmend that all were properly operated. As a result, in order to improve the inspection method for waste treatment facilities, it is necessary not only to accumulate quantitative standards for detailed inspection methods, but also to collect operational data for one year at the time of regular inspections of each facility, Grasping the flow and judging whether or not the treatment facility is properly operated. It is then determined that the operation and management efficiency of the treatment facility will increase.

The study is carried out to survey the proper management and to propose an eco - friendly separation system through efficient screening and resource recovery of excavated materials containing waste from various excavating fields such as reconstruction of landfill sites for reuse, reclamation of unsanitary landfill and residential land development of waste dumping sites. The current status and screening process and analytical characteristics of the excavated materials containing waste were reviewed. Through the analysis of the samples such as separated combustibles, recyclable soils and residues collected from the on-site visits we were able to understand the characteristics of separated materials and excavated materials containing waste such as calorific value, elementary composition, TOC, foreign material content and LOI. It has been found that elimination of the moisture of excavations, removal of attached soil from the surfaces of the excavated combustibles and the quantitative supply method of the input devices are the main operating factors as essential factors for the optimal separation of excavated materials containing waste. For efficient management and recycling of excavated materials containing, it is necessary to set criteria of ash content in separated combustibles and criteria organic matter content in separated soils.
