Abstract

Nigeria generates more than 32 million tons of solid waste annually, out of which only 20–30% is collected and disposed in an open dump site. Besides, reckless disposal of solid waste has led to blockage of sewers and drainage networks and choking of water bodies. More so, the problem of solid waste management has become one of the nation’s most serious environmental problems. In this research work, an investigation of municipal solid waste treatment in Okada community using a developed shredding machine was carried out. The shredding machine was developed and evaluated for performance using individual waste components. Parameters such as efficiency, shredding time, and machine throughput capacity were determined using food waste, paper waste, plastic, and nylon waste. Furthermore, the composition and analysis of the solid waste stream in the Okada community was carried out. The density, moisture content, and volume of municipal solid waste were determined. The values obtained were used to determine the daily amount of municipal solid waste generated in the Okada community. Load Count Analysis techniques were used to determine the volume of municipal solid waste generated daily. From the experimental results obtained, shredding techniques for solid waste treatment were most suitable for the Okada community. Besides, it was determined that food waste, with 28.0%, and plastic and nylon, with 21.0%, have the highest percentage composition of municipal solid waste generated in the Okada community. It was also revealed that food waste has the highest quantity of properly shredded waste (48.89 kg), and this was followed by paper waste, with a mass of 47.85 kg properly shredded. Furthermore, it was revealed from the research work that 3,027.6 kg of municipal solid waste will be generated daily in the Okada community. Besides, the developed machine was efficient because in each of the tests and evaluations of individual waste components, the efficiency obtained was above 80%.
