  • Pollution, climate change, and waste accumulation are only some of the new problems that have arisen because of the exponential population growth of the past few decades. As the global population expands, managing municipal solid trash becomes increasingly difficult. This is by far the most difficult obstacle for governments to overcome, especially in less developed nations. The improper open dumping of trash, which is causing mayhem across the country, has two immediate effects: it contaminates groundwater and surface water. Air pollution and the accumulation of greenhouse gases are both exacerbated by the release of methane and other harmful waste gases. Leachate from the landfill leaks underground and pollutes groundwater. In most cases, leachate moves into the groundwater zone and pollutes it after forming in association with precipitation that infiltrates via waste. This has far-reaching effects on people's health and disturbs the natural environment. This review article critically examines the current state of Solid Waste Management (SWM), addressing both the highlighted concerns and the government management solutions that have been put in place to address these issues. In addition, the constraints, and difficulties that India will face in the future in terms of solid waste management and the role of models for such a system are discussed.

  • In this paper, the expert system to reduce the amount of food waste is proposed. The method of material flow analysis (MFA) is applied. Proper handling of waste beyond the terms of the need for proactive research been mentioned before, but actually cause the waste generator research focuses on consumer behavior and the business community to analyze the flow of materials within the study are insufficient. In this paper, the type of food consumption and food waste, look at the relationship between the occurrence of secondary schools in the diet is provided for students to examine the preferences of the target model diet expert system was reconfigured. Preference for leaving the food in the diet leads to the important information that is Each diet recipes that make up the target material flow analysis (MFA) was constructed to perform all the database. This database is currently being generated from the rain while cooking diet edible plants and materials to reflect the self-esteem following the recommended diet is used to create. Reducing food waste is actually being used currently in research knowledge to the knowledge base was constructed. Future Home Smart System was developed in conjunction with the system to the user, by providing guidelines for the utilization can be expected.

  • The increased environmental concerns and the emphasis on recycling are gradually shifting the orientation of municipal solid waste (MSW) management. This paper is designed to evaluate regionalization programs for MSW management system. We developed a mixed intiger network programming (MIP) model to identify environment-friendly, cost-effective expansion plans for regionalization scenarios considered. The MIP model is a dynamic capacity expansion model based on the network flow model that depicts the MSW management cycle. In particular, our model is designed to determine the optimal form of regionalization using binary variables. We apply this model to assess the regionalization program of Seoul Metropolitan City, which includes three scenarios such as 1) districting, 2) regionalization with neighboring self-governing districts, and 3) g1obalization with all districts. We demonstrate how our model can be used to plan the MSW system. The results indicate that optimal regionalization with nearby self-governing districts can eliminate unnecessary landfills and expansions if jurisdictional obstacles are removed.

  • Municipal solid waste landfills are unpredictable bioreactors which in cases of mishandling and bad supervision presents numerous risks. The key to municipal waste landfills is to approach them from the point of prevention of the possible consequences, which means using methods of organized waste disposal, and also utilizing landfill gas, as an unavoidable consequence with disposal of municipal solid waste with a high share of biodegradable organic matter. This paper presents an overview about problems of solid municipal waste management, type and composition of waste, and an overview of waste management condition. Further, the problem of landfill and landfill gasses is described with the calculation models of landfill production, as well as the use of the SWM GHG Calculator and LandGEM software on a specific example of gas production for the central zone at Sarajevo landfill "Smiljevici". Main focus of this thesis is the analysis of potentials of greenhouse gas emission reduction measures from the waste management. Overview of the best available techniques in waste management is presented as well as the methodology used for calculations. Scenarios of greenhouse gas emission reduction in waste management were defined so that emissions were calculated using the appropriate model. In the final section of the paper, its description of the problem of collection and utilization the landfill gas at the sanitary landfill "Smiljevici", and implementation of the system for landfill gas collection and solution suggestion for the gasification and exploitation of gas. Energy, environmental and economic benefits can be accomplished by utilizing municipal solid waste as fuel in industry and energy and moreover by utilizing energy generation from landfill gas, which this thesis emphasizes.

  • 음식물쓰레기의 최대 배출원인 주택에서 생성되는 음식물쓰레기의 성상은 양호하여 재활용 가치가 크지만, 기존의 음식물쓰레기 관리방식으로는 한계가 있어 개선안이 요구되고 있다. 본 연구는 수도권과 비수도권 소재 공동주택단지의 음식물쓰레기 관리 실태를 조사하고, 발효 소멸기술을 이용한 음식물쓰레기 무배출 시스템 보급에 대한 지자체 태도를 파악하고자 한다. 전국 지자체 공무원을 대상으로 실시한 설문조사를 통해 수집한 자료는 통계분석을 하였고, 그 주요 결과를 요약하면 다음과 같다. 공동주택단지에서 배출되는 음식물쓰레기는 차량수거를 통해 퇴비나 사료로 재활용되고 있었다. 상당수의 지자체들은 음식물쓰레기 무배출 시스템에 관심이 있으나, 지자체의 예산 부족은 그 보급에 걸림돌이 되었다. 또한, 음식물쓰레기 무배출 시스템을 실용화하기 위해서는 비용절감효과, 에너지로의 자원화, 설치 후 유지운영 관리의 용이성 등이 뒷받침되어야 할 것으로 나타났다.

  • The introduction of Extended Producer Responsibility(EPR), voluntary agreements and operating were analyzed in this study. The voluntary agreement to participate in the manufacturers, recyclers and management reporting agency data and literature data to verify through research and analysis assessing the performance of the management plan for this system was analyzed. The effectiveness of Voluntary Agreement(VA) on waste analysis system of voluntary agreements with the voluntary agreement of waste reduction savings exemption amount and reductions in greenhouse gases, such as comparison and understanding of business organizations participate waste recycling effects were verified. The Voluntary Agreements as a means of future regulatory system for the ongoing operation of the waste recycling operations and systems effectiveness analysis of the problems appearing in operators and manufacturers suggest ways to improve it.
