An Environmental Risk Assessment Environmental Sciences Essay

An Environmental Risk Assessment Environmental Sciences Essay All over the world, rapid industrial development of metropolitan cities have always resulted in a growth in population and also in the general increase of the size of municipal solid waste generated. The management of municipal solid waste, if not handled properly, will lead to various problems now and in the future. Developed countries in the world have, to a large extent succeeded in handling their waste using various principles and methods. From suitable collection methods to technologically advanced disposal methods, they have made sure that municipal solid waste has been effectively controlled in their cities. Unfortunately, the same cannot be said about other developing countries of the world. Developing countries such as Nigeria are still battling with municipal solid waste management. As a direct result of the oil boom, Port Harcourt city, the capital of Rivers State, Nigeria (which is the case study of this research work) has experienced a major rural- urban migration. The population has almost tripled over the years. This has, in turn, led to a massive increase in the sheer volume of solid waste generated within the city.. Approximately 168,201 tonnes of solid waste are produced in the city of Port Harcourt every year and waste disposal has not been effectively handled. Residents resort to indiscriminate discarding of their waste at every given opportunity The most common means of waste disposal in the city by the public are mainly by dumping the refuse by the road, burning the refuse in the open air in their compounds, littering it openly on street corners and also dumping them in rivers and streams and drainage systems. These methods of waste disposal contribute greatly to the degradation of the environment in so many ways. However, very little is done to reuse and recycle the solid waste generated. Research shows that a huge percentage of the public do not recycle and reuse their wastes which indicates that the awareness level of the public about reuse and recycling of waste in Port Harcourt city is very low and offers a lot of prospect for improvement. This study therefore investigates the reasons why proper waste disposal methods are neglected by residents of Port Harcourt. It also seeks to discover why the method of Reuse and Recycle of waste is not getting the awareness and Government support it greatly deserves. Recommendations were made about strategies that will allow the government and stakeholders involved to advance on modern methods of waste Reuse and Recycling as a core aspect of municipal solid waste management in the city. Through the use of data collated via questionnaires, it was gathered that a majority of respondents agree that reuse and recycling of waste can positively impact the environment, create revenue and also employment opportunities. It reconnoitres the link between reuse and recycling of solid waste as a means to create revenue and to ultimately achieve sustainable development in the future. CHAP TER ONE INTRODUCTION BACKGROUND OF STUDY According to Shah (2000), solid waste is defined as any material that is unwanted or thrown away. The general community views waste as something worthless that should be destroyed or thrown away. As such, proper disposal of waste has constituted huge disposal problems. People commonly dump their household solid waste on the road side, unapproved dumpsites and illegal landfills. This has brought about untold environmental pollution as well as major setbacks in societal development (Mbata 2010). Waste in general is a threat to the environment, because of its negative environmental impacts that result from littering, dumping of wastes illegally, and greenhouse gas emissions (Hosetti 2006). Waste contaminates ground water and can cause serious health hazards if not handled and managed properly.
