Scope/Aim. Solid waste management in Ibadan Metropolis, the capital of Oyo State in Nigeria has been a serious concern to the government and the public for several years. The waste generated at the rate of about 0.51kg per capita per day from 11 Local Government Areas is transported to the existing four landfill sites and dumped indiscriminately. This study recorded various collection points using GPS, available collection bins, number of households using the facilities and identified the gap. Methods. The waste transportation routes used currently in respect of distance and travel time was assessed using a GIS analytical distribution and optimization mapping. Results. The results indicated that there is need for provision of 837 waste bins (5m3 capacities) to meet the demand gap. By following the optimized transportation routing, the waste management authorities can clear the waste 15 per cent more efficiently and save NGN 1.2 million (USD 3,335) on energy every year. Conclusions: The GIS analytical distribution and optimization mapping tool will help the city authorities in improving waste collection with significant saving in operational cost. It is replicable in other parts in African countries.

A qualitative research was conducted from March 2019 to August 2019 at KrongBong district general healthcare, Daklak province to evaluate the current situation of medical solid waste management at the hospital in 2019. The results indicated that most of the solid waste management at KrongBong District General Hospital have fulfilled the criteria specified in Circular 58. However, there still have some activities, such as there was no specialized waste transportation vehicle, the conventional solid waste storage was not performed well, the treatment of recycled solid waste was not in accordance with regulations. Besides, the hospital has not paid much attention to the inspection and supervision of solid waste management in departments and has not imposed sanctions, rewards or penalties for the waste management.

The study sought to assess the social context of solid waste disposal pattern of residents in Ibadan metropolis, in order to assess the Solid waste disposal patterns of people in Ibadan metropolis, Oyo State, Nigeria. Specifically, the study identified solid waste disposal habits of residents, frequency of clearing the dumpsters, accessibility of waste dumpsters to people determines the waste disposal pattern of people; and analyze the willingness of people in Ibadan to pay for improved service. Solid waste management has been part of human activities right from time. Efforts by Oyo State Government is seen in the collection of dirt that have been placed on the medians. Waste generation is an unavoidable product of man activities, however, sustainable management of such waste is a challenge faced in many countries today. Nigeria, a developing country in Africa, has been in a quandary of how to efficiently manage the municipal solid waste its population generates. Many states in the country lack adequate plans and infrastructure required for efficient and sustainable management of municipal solid waste. For Ibadan, the largest city in Nigeria, the problem is further compounded by its rather large and still increasing population. In this research, Ibadan metropolis is taken as a case study; the rate of solid waste handling in households as regards solid waste management from household collection to final disposal are focused upon. The study found out that 45.6% drop their refuse in the dumpsters as 18.8% burns their refuse, 17.7% of the respondents drops their waste on the median, 12% in the drainage while 6% opts to drop their waste in the streams. On the effectiveness of the Private operators collecting waste from the respondents, the study found out that 7.6% effective, 37.5% of the respondents says the operators waste collection is poor, 7% says it is abysmal while 43.5% said it is not applicable to them because they do not have storage containers in their houses and as a result did not subscribe to their service. Many countries, particularly the developed ones, have employed options in the waste management hierarchy for sustainable management of their municipal solid waste and the blend of options employed is usually highly dependent on local factors. Following the waste management hierarchy, possible options for sustainable municipal solid waste management in Ibadan are discussed. It is concluded that waste reduction, reuse, and recycling are potential management options for the state. Landfilling will remain an important option for final disposal but reliance on this method could be significantly reduced if management options are exploited to the maximum in a sustainable solid waste management structure in Ibadan metropolis.

The ineffective management of household solid waste (HSW) in most developing cities in Africa including Monrovia has become a major issue threatening the environment and public health. In response to these waste challenges, developed countries have embarked upon major environmental reforms, and have made advances in best practices and sustainable management of their Municipal Solid Waste (MSW). However, in most developing countries like Liberia, such environmental reforms have not been initiated and therefore the situation has become compounded; this is due to several factors impeding the development of a sustainable municipal solid waste system. This study, therefore, aims to critically analyze the influencing factors of solid waste management; the characteristics of household waste and suggest management solutions for effective and sustainable management.<br/> Results from the analysis of data, using The Ordinary Least Square Regression (OLS) method estimates the average household waste per capita generation as 0.76kg/capita/day. Regarding the composition of the waste stream, the results show that 67% of the waste sampled from Monrovia is biodegradable and mostly comprised of high wet weight and high moisture content kitchen waste. On the other hand, the remaining percentage is mostly non-degradable but recyclable materials such as glass ceramics and metals. This suggests that due to the high moisture content in the waste, samples are suitable for composting and other mechanical and biological management options. Using the stratified sampling method, 300 households were chosen. Multiple regressions were conducted to determine the relationship between waste generation and socio-economic factors and these showed that the effect of income, household size and the environmental concern on HSW generation is statistically significant at a 1% significance. However, further findings revealed a negative relationship between income and HSW generation at a 1% level of significance. These findings provide new insight regarding the role of socio-economic characteristics affecting the generation of household waste in Monrovia.

In sub-Sahara African countries, there exists apathy towards solid waste management and services. Indiscriminate waste disposal in Urora is addressed through a recent study which uses a combination of concepts from the sense of community, empowerment and phenomenological principles to explore how to engage households with other stakeholders to address the disconnect that has resulted in environmental degradation. The findings revealed that the problem of indiscriminate waste disposal in this community could not be meaningfully understood without understanding their communal living, behaviour and practices as mediated by rituals unmitigated by passage of time. Based on these results, this paper argues that ‘living in the community’ means taking an active part in the settlement’s physical environments for effective income generating opportunities.
