The increasing anthropogenic activities as a result of significant growth in population, urbanization, and industrialization has resulted in a tremendous amount of municipal solid waste (MSW). The municipal authorities are under extreme pressure from the epidemiological evidence towards human and environment as a result of injudicious waste disposal to landfills without any material recovery. In this article, the current status and limitations in treating MSW by the developing countries have been overviewed with a case study from Peshawar-Pakistan. The daily waste production in Peshawar city is about 650.8 tons with 0.4 kg/capita/day. Among the total waste, food waste contributes 14.3% fallowed by plastic waste (4%), paper (2.7%), glass (1.2%), wood (1.1%) and metals/rubber (0.6%). The waste collection efficiency is very low and about 40% of waste are collected whereas 60% of the waste remains in streets or at collection points. Currently there well-organized and specialized waste management practices such as composting, incineration, gasification, pyrolysis, biological treatment, and recycling for treating waste according to environmental deliberation. The directives of the developed countries had strictly imposed the regulations to increase the waste recycling and material recovery whereas in the developing countries the lack of proper legislation, planning, awareness regarding waste reduction has worsened the municipal solid waste-related problems. Moreover, in this article, an attempt has been made towards various important steps that need to incorporate in formulating the strategy for sustainable MSW management along with various aspects for their assessment in term of their sustainability in the developing countries.

Rapid urbanization and uncontrolled population growth in the city of Akure create a huge generation of municipal solid waste (MSW) and waste management authority has not been able to manage it properly. This has led to inefficient waste collection methods, insufficient coverage of the collection system and improper disposal of solid waste. This paper investigated municipal solid waste management practices in Akure, Ondo State, Nigeria. Simple random sampling was used in selecting 392 respondents within the eight districts in the study area. Information was collected on socio-economic characteristics of the respondents; nature and compositions of municipal solid waste and solid waste management practices in the study area. The study showed that female respondents (58.2%) were more than male (41.8%) in the study area. Also, a larger proportion of the respondents earned above N40,000 per month. More than one-third of the respondents (37.8%) created squander from vegetable and food remains, next to this were plastic (19.1%), paper (8.2%) and metal waste (6.6%). Further findings showed that the majority of the respondents (66%) do not segregate waste before disposal while the wastebasket was commonly preferred to collect waste due to its affordability. The study concluded that despite the establishment of waste management authority, most of the wastes collected was not sorted before disposal while the majority of the respondents preferred to burn their waste. The study recommended that government and non-governmental organizations should pay much attention to the issue of waste management in the area as waste was not properly managed.

AbstractMany cities in developing countries lack adequate drainage and waste management infrastructure. Consequently, city residents face economic and health impacts from flooding and waterlogging, which are aggravated by solid waste infiltrating and blocking drains. City governments have recourse to two strategies to address these problems: a) ‘hard’ infrastructure-related interventions through investment in the expansion of drainage and waste transportation networks; and/or, b) ‘soft’, low-cost behavioural interventions that encourage city residents to change waste disposal practices. This research examines whether behavioural interventions, such as information and awareness raising alongside provision of inexpensive street waste bins, can improve waste management in the city. We undertook a cluster randomized controlled trial study in Bharatpur, Nepal, where one group of households was treated with a soft, low-cost intervention (information and street waste bins) while the control group of households did not receive the intervention. We econometrically compared baseline indicators – perceived neighbourhood cleanliness, household waste disposal methods, and at-source waste segregation – from a pre-intervention survey with data from two rounds of post-intervention surveys. Results from analysing household panel data indicate that the intervention increased neighbourhood cleanliness and motivated the treated households to dispose their waste properly through waste collectors. The intervention, however, did not increase household waste segregation at source, which is possibly because of municipal waste collectors mixing segregated and non-segregated waste during collection. At-source segregation, a pre-requisite for efficiently managing municipal solid waste, may improve if municipalities arrange to collect and manage degradable and non-degradable waste separately.

The rapid increase in urban population has resulted in poor environmental conditions in urban and peri-urban settlements. In most developing countries, the problem of inefficient municipal solid waste management (MSWM) is endemic. The problem manifests in heaps of uncollected solid waste or ubiquitous illegal dumps on open areas and by the street sides. This paper examines issues of solid waste management practices in the City of Kwekwe in Zimbabwe. It highlights types of waste, its generation, transfer and disposal. A mixed methodological approach including field observations, structured questionnaire survey and face-to-face interviews were employed in the gathering of data for the study. The key findings established to be the factors affecting effective solid waste management in the City are irregular solid waste collection, inadequate operational funding, inappropriate technologies, inadequate staffing, lack of knowledge cooperation and knowledge on the part of the residents. Based on the research findings, principles of environmental stewardship need to be promoted in the City.
