1.1 Introduction
Domestic solid waste management refers to the systematic collection, segregation, transportation, treatment, and disposal of waste generated from households and residential activities in a manner that minimizes environmental impact and protects public health. It involves a range of strategies aimed at reducing the volume of waste sent to landfills through recycling, reuse, composting, and other sustainable practices (United Nations Environment Programme, UNEP, 2021). In modern urban settings, domestic solid waste has become one of the fastest-growing environmental challenges due to population growth, increased consumption patterns, and changing lifestyles.
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Domestic solid waste management is widely recognized as a fundamental component of environmental sustainability, urban planning, and public health protection. According to the United Nations Environment Programme (UNEP, 2021), solid waste refers to discarded materials generated from human activities, including household, commercial, and industrial sources, which require proper handling to prevent environmental degradation. Domestic solid waste, specifically, originates from residential settings and includes organic waste such as food remnants, inorganic waste such as plastics and metals, and hazardous household items. The management of these wastes has become increasingly important due to rapid urbanization, population growth, and changing consumption patterns across both developed and developing regions.
According to Adebayo and Afolabi (2019), the generation of domestic solid waste has increased significantly in urban areas, largely due to rising living standards and increased use of packaged goods. They reported that many cities in developing countries are struggling to cope with the volume of waste produced daily, resulting in inefficient collection systems and uncontrolled disposal practices.
Ogbonna, Ekwe, and Nwankwo (2020) asserted that poor waste management practices in urban communities contribute significantly to environmental pollution and public health risks. They stated that indiscriminate dumping of waste in open spaces, drainage channels, and water bodies leads to flooding, contamination of water sources, and the spread of diseases such as cholera, dysentery, and malaria.
Ayodele, Williams, and Ogunseitan (2022) asserted that, solid waste management strategies such as recycling, composting, incineration, and sanitary landfilling are essential for reducing the environmental impact of waste. They affirmed that integrated waste management systems, which combine multiple strategies, offer a more sustainable approach compared to traditional methods of open dumping and burning. However, they also noted that the implementation of such systems is often hindered by institutional weaknesses, lack of public awareness, and insufficient investment in waste management infrastructure.
UNEP (2021) reported that waste segregation at source is one of the most effective strategies for improving domestic solid waste management outcomes. It was stated that when households separate biodegradable and non-biodegradable waste, it becomes easier to recycle materials and reduce the volume of waste that ends up in landfills. However, in many developing regions, waste segregation practices is still at a low level due to limited public education and lack of enforcement of environmental regulations (UNEP, 2021).
Adeyemo and Oladipo (2018) reported that, informal waste pickers play a significant role in waste recovery and recycling in many urban centers. They contended that while the informal sector contributes to reducing the volume of waste in landfills, it operates under unsafe and unregulated conditions. In addition, Ogbonna et al. (2020) affirmed that community participation is a critical factor in the success of domestic solid waste management strategies. They reported that when residents are actively involved in waste reduction initiatives, compliance with proper waste disposal practices improves significantly. However, they also noted that public participation is often limited by low environmental awareness and lack of incentives to encourage sustainable behavior.
This study is set against the backdrop of increasing domestic solid waste generation, inadequate management systems, environmental degradation, and the urgent need for sustainable waste management strategies that can effectively address these challenges.
1.3 Statement of Problems
Investigation revealed that public awareness of proper waste segregation and recycling practices remains low, which increases the burden on final disposal sites and reduces the possibility of resource recovery from waste streams (Adebayo & Afolabi, 2019). Also, the absence of effective policy enforcement and monitoring mechanisms worsens the situation, as environmental regulations is often poorly implemented at the local government level (UNEP, 2021).
In many urban centers, the rapid increase in domestic waste generation without a corresponding improvement in waste management infrastructure is creating severe environmental stress. The inability of waste management agencies to adapt to increasing demand is further compounded by poor public participation in waste reduction initiatives. Households often do not practice waste separation at source, making downstream processing more difficult and costly.
Furthermore, many communities still rely heavily on open dumping and burning of waste, which contributes significantly to air pollution and greenhouse gas emissions (Ayodele et al., 2022). It is against this backdrop that this study seeks to examine domestic solid waste management strategies, assess their effectiveness.
1.4 Aim and Objectives of Study
