  • This study aims to analyze the factors that influence people's behavioral intentions to recycle waste and focus on people's perceptions of informal waste recycling. The low level of participation in the e-waste recycling process makes research on the factors that encourage household interactions in sorting waste or recycling waste a priority. The purpose of this study is to build a comprehensive model and examine the relationship between perceptions of informal recycling, implementation e-waste management, behavioral intention, convenience of recycling and perceived behavioral control. The framework is the Theory of Planned Behavior (TPB). The implementation variable e-waste management is used to mediate the relationship between the two constructs. Respondents in this study were cellular phone users who had changed their phones. The number of respondents in this study totaled 165, using the purposive sampling technique. Data analysis techniques in this study used PLS-SEM with WarpPLS version 6.0. The findings show that: (1) perception of informal recycling, e-waste management, and behavioral intention have a significant positive effect; (2) management of e-waste, perception behavioral control and behavioral intention have a positive effect; and (3) the implementation of e-waste management, which causes the convenience of recycling, will increase the intensity of behavior, indicating the results are rejected.

  • The management of municipal solid waste (MSW) is essential for every community; and, it is currently a major challenge in Nigeria. This paper provides an overview of the current MSW management trends in Nigeria and proposes new sustainable MSW management systems. Across Nigerian cities, MSW management is characterized by inefficient collection and transportation to disposal sites. Collection services do not reach some unplanned areas and slums due to poor street network. Even some planned areas are not reached by collection services. The informal sector contributes to waste collection, resource recovery and recycling; however, their activities are not recognized by the governments. Markets exist for recovered materials but more efforts need to be geared towards intensive recovery of materials and expansion of these markets. Despite the high proportion of putrescible matter in MSW, the only form of treatment commonly used currently is open burning for volume reduction. The high organic fraction presents a great opportunity for composting and anaerobic digestion. Ultimate disposal is currently done in open dumpsites. This needs to be upgraded to engineered landfills that are properly sited and adequately operated by well trained personnel. There is an emerging waste stream of concern, electronic-waste (e-waste), that requires urgent sustainable management as e-waste are currently co-disposed with other waste streams or burnt in the open posing detrimental health impacts.

  • 고준위방사성폐기물 처분을 위한 다양한 조사와 연구를 진행하는 과정에서 막대한 양의 자료가 생산되며 이를 관리하기 위한 자료 관리가 필요하다. 스웨덴의 SKB는 SICADA를 구축하여 부지선정, 평가, 해석, 분석 및 모델링에 활용할 수 있게 하였고, 독일의 BGE는 부지선정법에 따라 자료를 관리하기 위해 데이터베이스 및 문서 관리시스템 ArbeitsDB와 자료시스템 ELO를 구축하였다. 영국의 NWS는 DMS를 구축하여 연구, 조사 자료를 관리할 수 있도록 하였다. 미국의 DOE와 OCRWM은 부지특성화 조사를 진행하면서 자료 관리 및 이후의 인허가 절차를 위하여 TDMS를 구축하였다. 해외사례 조사, 분석을 통해 자료의 품질관리와 자료 활용의 확장성이 자료 관리에 있어 중요한 부분임을 확인할 수 있다. 향후 우리나라도 장기적인 관점에서 자료의 품질관리와 확장성을 고려한 자료 관리 개념을 확립하고 그에 맞춘 자료 관리 시스템 및 체계를 구축해야 할 것이다.

  • E-waste(폐전기전자기기, WEEE)는 많은 종류의 금속을 함유한 유가물과 유해물의 복합혼합물로 자원의 유효이용과 환경부하저감을 위해 리싸이클링 처리가 필수로 되어 있다. 특히 최근 레어메탈의 공급제약문제 등으로 도시광산자원 중에서 E-waste의 비중이 높아지고 있다. 한편, E-waste의 리싸이클링산업에 있어서 E-waste의 경제적 가치의 파악은 매우 중요하다. 이와 같은 관점에서 본보에서는 E-waste를 대형가전, 소형가전, 휴대전화기 및 PCB(전자인쇄회로기판, 기판)로 분류해서 경제적 가치를 논하였다.

  • E-waste는 종류가 많고 유통경로가 다양하여 눈에 보이지 않는 흐름이 주류를 형성하고 있다. E-waste에는 레어메탈의 사용이 많을 뿐 아니라 유해한 중금속도 함유되어 있어 자원확보면에서, 환경오염방지면에서 재자원화 처리가 필수적이며 정확한 재자원화 물질흐름의 분석이 요구되고 있는 실정이다. 이러한 관점에서 2008년 1월부터 실시한 "전기 전자제품 및 자동차의 자원순환에 관한 법률" 중에서 E-waste와 관련된 법률내용의 골자, 리싸이클링시스템, 리싸이클링현황, E-waste 배출량 추정과 물질흐름 및 PCB의 경제학을 논하였다. 그리고 현시점에서 한국의 E-waste 재자원화산업을 약술하였다.

  • The accelerated increase of the population growth rate in the world and the current lifestyle based on consumerism considerably increased the amount of waste generated by the human activity. Specifically, e-plastic waste causes significant damage to the environment because of its difficult degradation process. This paper aims to establish the feasibility of using e-plastic waste in concrete as a partial replacement of coarse mineral aggregate. Considering a control mix without e-plastic waste designed for a compressive strength of 21 MPa, tests on concrete mixes with 40, 50 and 60% of e-plastic waste aggregate to determine the fresh and hardened properties were carried out. A reduction in the compressive strength as the percentage of e-plastic waste increases was observed, the maximum reduction being 44% with respect to the control mix. In addition, a significant reduction as much as 22% in the density of the concrete mixes with e-plastic waste was recorded, which means that lighter elements can be produced with this type of concrete. Two new equations based on regression analysis of the experimental data from this study were proposed. These equations estimate the reduction in the compressive strength of concrete mixes with e-plastic waste aggregate at 14 and 28 days. A cost analysis and a practical alternative to introduce this waste material into the market are also presented.

  • The municipal solid waste (MSW) management system in one of the Class II Indian cities i.e. Rishikesh was studied and analysed to identify the key issues in solid waste management in the city. A total of 329 solid waste samples from 47 households were collected to characterize the household solid waste (HSW). The average (HSW) generation rate was 0.26 kg/c/d and it was composed of organic waste (57.3%), plastics (14%), paper (10.9%), and glass and ceramic (1.3%) and other materials (16.5%). There was an inverse relationship between household waste generation rate and family size (p < 0.05). The MSW management system practiced in Rishikesh is unsound. There is no waste segregation at source, no provisions of composting and no recycling by formal sector. The collection and transportation of waste is inadequate and inappropriate. Collected waste is dumped in open dumping site without scientific management. Following are some recommendations for developing a sustainable solid waste management system in Rishikesh city: (1) sensitize people for segregation at source; (2) promote reduction, reuse and recycling of wastes; (3) promote community based composting; (4) provision for 100% door to door collection and; (5) formalize the informal sectors such as rag pickers and recycling industries.

  • China's e-waste enterprises can decompose 150 million sets of e-waste every year, but in fact, only about 50% of the e-waste goes into formal recycling due to the informal recycling of individual small businesses. The purpose of this paper is to put forward the method for users to improve the reuse times through regular e-waste recycling enterprises. This paper constructs the evaluation factors of reuse logistics service through prior research. Exogenous variables are mainly composed of the management system, economics, resources, policies, social perspectives, and service quality. In addition, the authors choose intention to reuse as an endogenous variable. A total of 335 questionnaires were collected to conduct the research with the structural equation modeling. The results reject the hypothesis that economics, resources, and social perspectives have a positive impact on reuse. On the contrary, management systems, policies, and service quality have a positive impact on reuse. Implications were suggested in the last part of the research.

  • 제4차 산업혁명 흐름과 COVID-19 팬데믹으로 증가한 전자부품 수요는 인류의 삶을 편리하게 만들었지만, 전자폐기물의 발생량 또한 증가시켰다. 전자폐기물의 영향에 대한 논의는 환경, 건강, 사회문제 관점을 중심으로 이루어져 왔고, 전 세계의 법령도 이러한 문제들을 해결하는 데 초점을 맞추어 왔다. 하지만 일반적인 폐기물과 달리 전자폐기물에서는 기술 유출 및 개인정보 유출과 같은 보안 문제가 발생할 수 있다. 현재 전자폐기물 보안에 관한 논의는 다른 분야에 비해 매우 부족한 수준이다. 이에 본 연구는 상대적으로 덜 주목받았던 전자폐기물 보안 동향을 실증적으로 분석하고자 하였고 세 가지 접근법을 적용했다. 첫째, 연도별 문헌과 언론보도의 추세를 분석하여 전자폐기물에 관한 전반적인 논의 추이를 파악했다. 둘째, 전자폐기물 보안 위험을 다룬 문헌들을 분석하여 해당 분야의 키워드를 바탕으로 전자폐기물 보안 동향을 파악했다. 셋째, 각종 보안관련 국가지침 내 전자폐기물 처리 관련 규정을 검토하고, 이를 통해 전자폐기물 보안 대책 설계 필요성을 평가했다. 본 연구는 국내에서 거의 처음으로 전자폐기물을 보안 관점에서 다룬 연구라는 점과 전자폐기물 보안 동향을 다차원적으로 분석했다는 점에 의의가 있다. 전자폐기물 보안 동향 분석 결과는 전자폐기물과 전자폐기물 보안 문제에 대한 국내의 인식을 높이고 전자폐기물 보안 위험에 선제적으로 대응할 기회를 제공할 것으로 기대된다.
