Semarang City is working on constructing a Material Recovery Facility (MRF) in various urban villages to reduce the waste that enters the Jatibarang Landfill. However, the construction of MRF is not optimal. MRF Purwosari still functions as a container without waste processing. By projecting waste generation for the next ten years, the results of optimization planning are processing waste into RDF, redesigning MRF covering an area of 1,571 m2 with an investment cost of IDR 1,602,837,997 and an operational cost of IDR 307,741/ton/day. The NPV value was Rp.4,836,965, EIRR 12%, and BCR value of 1.81.

Abstract: This paper aims at determining the recent composition of municipal solid waste of Gwalior city and provide sa notion to take action and proposed economical & viable waste management technologies and techniques for effective utilization of waste. In this study, MSW samples were collected from the Kedarpur landfill site situated at Shivpuri link road and were analyzed for physical composition. The study reveals that Gwalior city produces a high quantity of biodegradable waste (58.03%) with high moisture content (68.60%) and plastic waste (15.96%). Waste composition and characterization disclosed that vigorous segregation is required before dispatching the waste for different treatment processes or landfilling. Based on this study, we may conclude that the combined mechanism of planning and implementation of waste-to-energy (WTE) technologies and treatment such as Anaerobic Digestion/ Bio-methanation, Material recovery facility (MRF), and Bio-remediation/Bio-mining for old existing waste and new generating waste is needed for upgrading the waste management scenario of the city.

Managing solid waste is becoming a rather challenging task in remote areas, including the Mt. Everest region in Nepal, due to its cold climate, complex topography, and extreme environmental factors. Using published and unpublished literature and personal communications to key informants, this paper analyzes the situation of solid waste management in the Everest region as it relates to increasing tourism and possible environmental implications in the region. The study revealed that combined efforts from people of all levels associated with the mountain region would create a circular waste management system. The paper also reports the existing practices and planned activities for the essential process such as source segregation of waste, collection, use of material recovery facility, and recycling which could lead to sustainable solid waste management in the Everest region and beyond with similar context.

Tujuan dari penelitian ini adalah mengetahui timbulan dan komposisi sampah kemudian merencanakan pengelolaan sampah terpadu berupa pewadahan dan pengumpulan sampah serta pengolahan sampah menggunakan Material Rocovery Facility (MRF) di Perumahan Kota Citra Graha. Untuk menentukan pengelolaan sampah terpadu yang tepat dilakukan pengambilan dan pengukuran contoh timbulan dan komposisi sampah berdasarkan Standar Nasional Indonesia (SNI) 19-3964-1995. Dari hasil pengambilan dan pengukuran contoh ini diperoleh besarnya timbulan sampah yaitu 2,27 liter/orang/hari dan 0,361 kilogram/orang/hari yang terdiri dari 71,75 % sampah basah, 18,64 % sampah kering dan 9,61 % residu. Sistem pewadahan sampah yang direncanakan adalah pewadahan semi tetap sistem terpisah dengan pola pewadahan individual. Sedangkan desain alat pengumpulan sampah berupa gerobak motor dengan pemisahan antara sampah basah dan sampah kering.Material Recovery Facility(MRF) yang direncanakan terdiri dari lahan pemilahan, lahan penampungan sampah organik, lahan pencampuran sampah dengan inokulan (biostater), lahan pencacah organik, lahan pengomposan, lahan pematangan, lahan pengayakan dan pengemasan kompos, lahan penampungan lindi, gudang barang sortir, gudang kompos, kantor administrasi, area parkir gerobak motor dan area kontainer. Kata Kunci: Perumahan Kota Citra Graha, pewadahan sampah, pengumpulan sampah, Material Recovery FacilityThe objective of the research was to know solid waste generation and composition then to design integrated solid waste management in the form of solid waste lug, collection and treatment using Material Rocovery Facility (MRF) in Housing Kota Citra Graha.

Rapid and uncontrolled urbanization in several parts of sub-Saharan Africa (SSA), has introduced a plethora of urban development challenges. This has left city governments ‘standing in their sleep’, as they strive to deal such issues. A classic example is solid waste management – with waste considered to be principally an urban problem. While the issue of waste has been belaboured in the literature, there is a dearth in geographical literature on the institutional dynamics of solid waste management. Viewed as structures and processes, institutions demonstrate potentials to determine the intentions and actions of urban waste managers and urban dwellers, within the waste management spectrum. Taking the case of Bamenda – a primate city par excellence – this paper explores the dynamics of institutions and their implications for solid waste management. Specifically, it explores the waste management institutional transition and its bearing on current and potentially, future waste management practices. Household surveys, complemented by expert interviews provided data for the study. Through narratives and descriptive statistics, we observed that despite the litany of institutions involved in solid waste management and their related institutional frameworks, their effectiveness remains questionable. This rests, in part, on the inadequacy in personnel, and the lack of law enforcement in the courts and city judiciary systems. The ineffectiveness of these instruments in the Bamenda Municipality is as a result of weak legal institutional setup, the absence of courts and a city judiciary system to handle environmental issues (solid waste), irregular or poorly enforced laws, inaccessible neighbourhood, and organizational lapses. Furthermore, the socio-political climate, characterised by insecurity, mars the effective implementation of waste management approaches. This paper argues that the institutional change process in waste management should strive towards the introduction of economic incentives that can motivate urban dwellers to fully engage in the process. Further empirical evidence on the right business-oriented waste management models are required to ground this claim.

Waste to energy is only one way of handling waste, material recovery is another aspect of sustainable waste management. This is actually nothing new and has always been part of the operation of WTE (Waste to Energy) plants in Hamburg. In descriptions of the first waste incineration plant in Hamburg, which started operation in 1896, it was stated that “the fly ash” collected in the ash chambers was used as filler material for the insulation of ceiling cavities. Its use in the sandwich walls of money safes was expressly recommended by the members of the urban refuse collection authority. Another lucrative trade was the sorting of scrap iron. It was separated from the incineration slag with magnets. The slag itself was said to be as sterile as lava, as hard as glass, as useful as bricks, and it was a profitable side product of waste incineration. The crushed incinerator slag was evidently so much in demand in road construction and as an aggregate in concrete production that demand could often not be met in the building season, even though it was stored through the winter, [1,2,3].
