“…Waste collection and disposal are the major problems faced by developing countries in solid waste management (Aliu et al, 2014). Yet, it is one of the most difficult operational problems faced by most urban areas in Nigeria (Ogwueleka, 2009a). Udoh and Inyang (2016) reported some of the solid waste collection problems which include; singular dumpsite in the study area resulting to inherent routing issues, singular type of waste receptacle used for all categories of waste, size of bins not considered for overpopulated areas leading to opened receptacles, and overflow of waste which subsequently serves as a breeding ground for rodents, fleas and vermin.…”

The global population and increased urbanization have resulted in the increased production of municipal solid waste, thus, becoming a critical issue as a result of its poor management and inappropriate disposal. This is particularly the case of developing countries. This study assessed Solid Waste Management (SWM) strategies commonly adopted by different state waste management Authorities in Nigeria with a view to develop a sustainable roadmap for the management of solid waste in Nigeria. It assessed the Traditional Solid Waste Management Strategy (TSWMS), Waste Minimisation Strategy (WMS) as well as the Technological Strategy (TcS) employed, laying focus on their challenges and benefits. The study depended on a desktop study approach; hence, data were obtained from secondary data as the main source of information with emphasis on published journals, conference papers, newspaper posts and statutory reports from government agencies relevant to the current study. Results from the review showed that waste management across various parts of Nigeria is poor, interwoven with several challenges at all phase of the management process with little benefits recorded on alternative SWM strategy. The reason for the low success rate of some of this management strategies were noted as; increase in population, area covered, increase in urbanization and industrialization, tenure of government, over dependence on government authorities for waste management, finance and other factors of the environment. Although most waste authorities rely heavily on the TSWMS, WMS and the TcS showed a better and promising alternative strategy when inculcated into the already existing strategy. Based on this finding, a roadmap for the actualization of a sustainable integrated solid waste management strategy was recommended for adaptation and adoption by the Nigerian SWM Authorities and Agencies.

ABSTRAK Penelitian ini bertujuan untuk memetakan sebaran tempat pembuangan sampah (TPS) ilegal dan menganalisis faktor-faktor yang mempengaruhinya. Penelitian ini dilakukan di Kota Banjarbaru, Kalimantan Selatan. Data penelitian diperoleh melalui pengamatan dan pengukuran secara langsung di lapangan serta studi pustaka. Seluruh data yang diperoleh, baik yang berbasis geografis maupun yang bersifat deskriptif dan numerik diolah dan dipetakan dengan menggunakan perangkat lunak ESRI ArcView GIS 3.3. Hasil penelitian menunjukkan bahwa di Kota Banjarbaru terdapat 64 lokasi TPS ilegal dan sebarannya dipengaruhi oleh jarak dari sungai, jarak dari jalan utama, jarak dari jalan lokal, tutupan lahan, kepadatan penduduk, tingkat pendidikan, jenis pekerjaan, cara membuang sampah, cakupan wilayah layanan pengangkutan sampah dan jarak dari TPS resmi.Kata kunci: Kalimantan Selatan, pembuangan sampah ilegal, pemetaan, sampah domestik, sistem informasi geografis

“…Karadimas et al (2007) used, may be for the first time, ArcGIS Network Analyst and examined an area of 1.34 km 2 and just one route in Athens, Greece and achieved a saving of 20% in route length. Ogwueleka (2009) used extended capacitated Arc Routing Problem and reduced 16.31% of the distance travelled. Chalkias and Lasaridi (2009) used ArcGIS Network Analyst in the Municipality of Nikea, Greece and reduced the distance of vehicles travel by 5.5%.…”

Worldwide, about US$410 billion is spent every year to manage four billion tonnes of municipal solid wastes (MSW). Transport cost alone constitutes more than 50% of the total expenditure on solid waste management (SWM) in major cities of the developed world and the collection and transport cost is about 85% in the developing world. There is a need to improve the ability of the city administrators to manage the municipal solid wastes with least cost. Since 2000, new technologies such as geographical information system (GIS) and related optimization software have been used to optimize the haul route distances. The city limits of Chennai were extended from 175 to 426 km(2) in 2011, leading to sub-optimum levels in solid waste transportation of 4840 tonnes per day. After developing a spatial database for the whole of Chennai with 200 wards, the route optimization procedures have been run for the transport of solid wastes from 13 wards (generating nodes) to one transfer station (intermediary before landfill), using ArcGIS. The optimization process reduced the distances travelled by 9.93%. The annual total cost incurred for this segment alone is Indian Rupees (INR) 226.1 million. Savings in terms of time taken for both the current and shortest paths have also been computed, considering traffic conditions. The overall savings are thus very meaningful and call for optimization of the haul routes for the entire Chennai.
