SOLID WASTE MANAGEMENT AND DISPOSAL SYSTEMS. A RESEARCH PROJECT TOPICS ON CHEMICAL ENGINEERING
This seminar topic “Solid Waste Management and Disposal system” is based on the research on what solid waste is all about, how it is managed and its methods of disposal systems. Research on this topic enable us to know that solid wastes are discarded solid materials such as scraps of plastic, rubbers nylon, paper, etc. Also, the collection and processing of these wastes as well as disposal constitute the management of solid wastes. The disposal systems tell us the methods of disposing solid wastes and where they are disposed as well as the transportation of the collected materials. From this seminar,solid wastes are separated into various components and recycled to produce good and usable products. The effective waste management and disposal system result into a clean and healthy environment for living, reduces the spread of diseases and aids the growth of the economy.
WHAT IS SOLID WASTE?
The United States Environmental protection Agency defined a solid waste as any uselss, unwanted or discarded material with insufficient liquid content, EPA (1975). Because of its sticky nature, a solid Waste has the quality of accumulating, and physically insulting the environment. Omuta (1988), defined a solid as plastic, rubber, paper, glass, etc arising from domestic, trade, commercial, agricultural and industrial activities. Moreso, solid matter that are created by human or animal activities and which are disposed because they are considered useless are known as solid wastes. Most of the solid wastes like plastic, robber, etc. are non. Biodegradable which means that they do not get broken down through organic processes thus, when they accumulate, they pose a health threat to the people. According to Eze (1995), a solid waste means any refuse, gabbage and other discarded materials resulting from community, agricultural and industrial operations.
CLASSIFICATION OF SOLID WASTES
According to Umeh (1991), solid wastes have potential to cause harmful effect if not properly managed. He classified solid wastes into the following.
– Garbage: decomposable wastes
– Rubbish: non-decomposable wastes such as plastic, Rubber,etc.
– Dead animals.
– Large wastes: Wastes from construction and demolition of structures.
– Industrial wastes: such materials like scraps of plastic, rubber etc.
