Abstract

The Oyo State Solid Waste Management Authority (OYSWMA) hired private waste operators (PWOs) because the government was unable to handle the increasing amounts of solid garbage that were being carelessly deposited in every corner of the metropolis. This study looked at the private garbage contractors' methods of operation, clientele, and difficulties in managing residential solid waste in Ibadan, Nigeria. In the three local government districts of the metropolis, a structured questionnaire was given to 21 private refuse operators and 250 homes. A few measures of service quality were employed to determine the method of operation and customer base. To interpret the gathered data, both descriptive and inferential statistics were employed. The findings showed that the factors that affected residents and operators of SWM the most were educational attainment, monthly income, building types, and occupation (n = 213, 85.2%; 164, 65.6%). Of the houses who enrolled for waste collection, between 201-300 (47.6%) and 100-200 (42.9%) utilized private waste contractors. Although the license specifies once per week, waste collection is inconsistent and typically occurs once every two weeks (52.4%); charges, on the other hand, are variable and exceed the established rates. Undue financial backing from the LGAs, impassable areas, incompatible law, poor advertisement and awareness, political influence, exorbitant leachate treatment fees, and poor health were among the operational issues confronted the private garbage operators. The elements that affect the way the private sector of SWM operates and attracts customers were found to be as follows: non-cooperation of residents (n = 8, 38.1%), poor nearness to buildings (n = 9, 42.9%), and the lax enforcement of hygiene regulations (n = 4, 19.0%). The report suggests that in order to provide residents in Ibadan Metropolis with high-quality services, private refuse operators should regularly monitor and oversee the collection of solid waste.

Abstract

Given the current rate of urbanization, municipalities in most Nigerian cities have struggled with the collection, transportation, and disposal of solid waste. This is due to waste generation, both residential and commercial, occurring in a dispersed manner across homes, buildings, streets, parks, and even vacant spaces within communities. This manuscript aims to evaluate the state of municipal solid waste management in Ibadan, household solid waste storage practices, and the locations of solid waste storage containers (skip points) in relation to accessibility and health risks to the community, in accordance with Nigerian National Solid Waste Management Standards and other pertinent international standards. A structured questionnaire was distributed to 21 micro and small firms and 250 homes in each of the three local government areas of the metropolis, with descriptive statistics used to interpret the data. According to the study results, inadequate Municipal Solid Waste Management (MSWM) service delivery in the Ibadan metropolitan area can be attributed to several issues, including a lack of institutional coordination among urban planners. The study’s conclusions indicate that the state of MSWM in the sampled areas is either inadequate or has poor spatial coverage and container utilization. Lastly, the study primarily suggests that these measures can reduce problems associated with MSWM by encouraging public-private partnerships, fostering effective institutional coordination with urban planner consultants in MSWM and skip-point location, and motivating the community to adopt integrated sustainable Solid Waste Management (SWM) strategies.

Abstract

This work evaluated the mobility and bioavailability of arsenic, copper and zinc in chosen poultry farmlands situated within Osun State, Nigeria in respect to the soil physicochemical characteristics. The site was split into 12 zones of about equal sites. Soil samples were collected over a period of four months from each zone for analysis of soil physicochemical characteristics and As, Cu and Zn contents in sequential fraction of the soil sample. Sequential fractionation of soil samples were conducted utilizing reworked Tessier technique, utilizing Flame Atomic Absorption Spectrophotometer. Mean of total content (mg/kg) and percentage bioavailability were: As 470.48±48 (31.16%), Cu 62.95±10.61 (29.02%) and Zn 125.58±20.74 (26.67%), respectively. Analysis of variance and correlation analyzes indicated that soil pH, % clay, % organic carbon, cation exchange capacity, and metal speciation in soil control metal mobility and bioavailability in the poultry farm soil. The mean contents of As, Cu and Zn in soil in the sampling area were usually more than those of the control site, indicating some degrees of contamination of the poultry farm soil by these metals. Also, the mean contents of As in some zones were considerably greater (p
