**1. Introduction**

Industrialization, which meets the needs of a rapidly increasing global population, is the backbone of economic development and human welfare in any society. However, the proliferation of industries and industrial activities in many countries, especially developed countries in Europe and America, has led to environmental pollution and eco-deterioration around the developed world. Industries in less developed countries of Africa and the Sahel are no different as the impacts of their activities on the environment continue to produce far more deterioration due to poor pollution management and control. For instance, Teku [1] and Firdissa et al. [2] stated that in Ethiopia, rapid industrialization has led to the generation of industrial wastes including hazardous wastes, and improper management of the vast amount of these wastes is one of the most critical environmental problems in Addis Ababa. One of the main concerns of environmental engineers and activists in Nigeria, especially in the state of Lagos with a small land mass in comparison with its large population, is the everexpanding solid waste landfills and their attendant environmental degradation caused by leachate formation (**Figure 1**), which can contaminate arable agricultural land, surface water, and aquifers [3].
