In order to promote recycling of animal and plant residues, it is necessary to prepare detailed statistics on the sources, generation amount and the state of disposal so that waste recycling companies and enterprises can obtain the information easily. Also, the recycling methods specified in the law should be appropriate. For this, the study reviewed the appropriateness of detailed classification of animal and plant residues and permitted recycling methods in the Enforcement Regulations of the Waste Management Act of Korea. For improvement of the detailed classification, the study conducted literature review on European and Japanese ones. Additionally, we visited slaughterhouses of livestock and poultry, vegetable oils manufacturing companies, starches and glucose or maltose manufacturing companies, which generate the waste and recycle the waste, to grasp the status of recycling in Korea. Based on the results, the study proposes improvement measures for the detailed classification and the permitted recycling types in the law.

Korea has an economy based on manufacturing industrial fields, which produce high amounts of hazardous wastes, in spite of few landfill candidates, and a significant concern for fine airborne particulates; therefore, traditional waste management is difficult to apply in this country. Moreover, waste collection and accumulation have recently been intensified by the waste import prohibitions or regulations in developing nations, the universalization of delivery services in Korea, and the global COVID-19 crisis. This study thus presents a domestic waste management strategy that aims to address the recent issues on waste. The contents of the strategy as the main results of the study include the (1) improvement of the compatibility of the classification codes between the domestic hazardous waste and the international ones such as those of the Basel Convention; (2) consideration of the mixed hazard indices to represent toxicity from low-content components such as rare earth metals often contained in electrical and electronic equipment waste; (3) management application based on risks throughout the life cycles of waste; (4) establishment of detailed material flow information of waste by integrating the Albaro system, Pollutant Release and Transfer Register (PRTR) system, and online trade databases; (5) real-time monitoring and prediction of the waste movement or discharge using positional sensors and geographic information systems, among others; and (6) selection and implementation of optimal treatment or recycling practices through Life Cycle Assessment (LCA) and clean technologies.

Purpose: In order to improve the energy performance of existing buildings, so actively promoted green remodeling business. Also, improvement of the performance of envelope system of apartment housing is an absolute. The purpose of implementation of the data base and application plan of the envelope system for green remodeling of apartment housing. Method: For this study, It proposed a classification system of green remodeling envelope system constructed actual to select the applicable representative method and input material of apartment housing for green remodeling. In this study, divided into construction waste processing stage and production phase of the material for the boundary of the system, and implementation the classification system of the envelope system for applicable green remodeling. For this, established 6 environmental impact categories database. Result: As a result of various suggestions were available for case study research, alternative combinations of existing combinations than six kinds of environmental impact insulation system with superior input materials combining 96 kinds, window system, 12 kinds for determining the applicability of the established database. Depending on the account for a large proportion if compared to the detailed analysis of the environmental impact resulting from the production phase and disposal phase was analyzed that the operating management of the necessary input materials. Is considered that the economic performance and integrated energy performance required by the applicable public housing green remodeling evaluation techniques considered for future improvements insulation sheath.
