Which One is Best? Household Solid Waste Collection Facility Siting in a Developing Countries’ Autonomous Region

Abstract

In many developing countries, the regencies in them have a relatively high degree of autonomy one of which is related to rights to place capacitated waste collection facilities from which the waste is conveyed to final waste clearance facilities. The rights include the management of waste generated by the waste producers at some places yet, due to limited budget, do not touch the waste management at this lowest level at other places. Given the growing importance and emergence of waste-related issues, the paper deals with the problem of siting household solid waste collection facilities within the context of an autonomous region. A waste-weighted P-median, a pure P-median, a P-centre, a P-dispersion and a “distance gap” models are proposed for the problem. By using data obtained from Karanganyar Regency, the Republic of Indonesia, as a problem context, the paper concludes that the best model for the siting problem in such regions is driven by the objective of the siting itself. Moreover, the paper suggests that collection facilities with large capacities should be given a lot more attention in terms of having anticipation to the demand of household solid waste the regions will have in the future.
