ABSTRACT
Effective management of wastes on Nigerian highways has emerged as one of the greatest challenges being faced in the country. The generation of wastes in the country has increased considerably with its adverse effects as the hazard posed by this problem cannot be overemphasized. The paper analyses the effects of poor waste management on highways with a focus on the Abuja-Keffi expressway. It also identified the sources of wastes, solid waste types and categories, collection, disposal, management methods and factors hampering effective solid waste management. The study reviewed the current solid waste management practices in Nigeria. Data gathered from the study shows that, improper disposal of municipal waste has serious and dangerous impacts on the environment, humans, plants and animals. Environmental hazard, health hazard, depletion of the ozone layer, flooding, ugly scenario of the environment, human injury etc. were identified as some of the effects of poor waste management. Findings however revealed that, ineffective solid waste management on highways is characterized by improper disposal, inefficient collection methods, laziness, ignorance and insufficient coverage of the collection system while reduction, reuse and recycling are some of the strategies that could be employed for an effective waste management on highways. The paper in conclusion makes succinct recommendations for government, professionals, highway managers and the general public on the need to brace up for the challenge posed by this menace.
