LANDFILL EMISSIONS AND THEIR IMPACT ON THE ENVIRONMENT IN NIGERIA

 

INTRODUCTION

Cities are at the centre of a new environmental threat: the generation of a rising quantity and complexity of waste. Global Municipal Solid Waste (MSW) generation is projected to be between 1.7 and 1.9 billion metric tonnes.2 Municipal garbage is often poorly handled in developing nations because towns and municipalities are unable to keep up with the rapid pace of waste generation.

Low-income countries frequently have waste collection rates below 70%. More than half of the collected waste is frequently disposed of through uncontrolled landfilling, with around 15% processed through dangerous and informal recycling. Landfill Emissions

Municipal Solid Waste Management

As Mayor, you may be faced with difficult waste management decisions that address both urgent difficulties and potential issues that require strategic and coordinated planning and implementation. Establishing and enhancing MSW collection, recycling, treatment, and disposal facilities can be extremely costly.

Building and managing sanitary landfills and incineration plants, for example, necessitates large investments as well as significant operational and maintenance costs.

Furthermore, the prevalence of the Not In My Backyard (NIMBY) mentality in communities makes it increasingly difficult to find acceptable locations for waste treatment plants. Landfill Emissions

Meanwhile, if garbage grows at 3-5 percent each year and rural-urban migration raises a city’s population at the same rate, waste creation will double every ten years.

4 Urban managers are therefore encouraged to pursue the paths of Integrated Solid Waste Management (ISWM) and Reduce, Reuse, and Recycle (3Rs), which prioritise waste prevention, waste reduction, and waste recycling over simply dealing with ever-increasing amounts of waste through treatment and disposal.

Such initiatives will assist cities in reducing the financial load on municipal authorities for trash management, as well as the pressure on landfill requirements. We live in a world of growing scarcity.

Raw materials derived from natural resources are scarce, financial resources are frequently insufficient, and obtaining land for eventual disposal is becoming challenging. Landfill Emissions

If local governments are to ensure a clean, healthy, and pleasant living environment for present and future generations, they must clearly establish policy directives aimed at resource efficiency and recycling.

Although cities and municipalities bear primary responsibility for waste management, many effective cases involve a diverse variety of stakeholders in their implementation, as evidenced by the case studies cited here.

This sends a strong message to cities and municipalities that they should not try to handle everything on their own. Rather, the key to success is to do what they do well and engage with other sectors of society, such as the commercial sector, communities, and, in some circumstances, the informal sector, in order to increase waste management services while enhancing efficiency and effectiveness.
