IMPACT OF RECYCLING IN PRESERVING THE ENVIRONMENT
Chapter one
INTRODUCTION
1.1 Background of the Study
The production and disposal of garbage is an inherent component of any developing or industrial society. Waste from both residential and commercial sources has increased dramatically in Nigeria during the last decade.
Every time a householder shops at a store or an open market, he contributes to the pile of rubbish. It is conceivable to quote numbers indicating that waste output totals millions of tonnes.
The proportion of Nigerians living in cities and urban regions has more than doubled during the last 15 years. Cities and metropolitan regions are constantly growing, resulting in massive amounts of solid and liquid garbage.
Waste management is a national and international concern. The volume of waste is not the issue, but rather the ability or unwillingness of governments, individuals, and waste disposal companies to keep up with the work of managing waste and the environment.
There is no doubt that a polluted environment has an impact on people’s living standards, aesthetic sensitivities, health, and, as a result, their quality of life. The implication is that inappropriate disposal or storage of this waste can pose a risk to society by polluting the air, land, and, particularly, water.
Domestic garbage will be the focus of this investigation. We shall discuss some of the issues that have plagued the handling of this type of garbage in Nigeria today. It can be seen that Nigeria has not done well in terms of addressing the problem of residential garbage.
This is despite the fact that advanced management solutions for home trash management are now available and widely used. We shall make proposals to help address this issue, which appears to be thwarting most efforts by international organisations, the federal government, city authorities, states, and specialists alike.
Recycling is based on waste items that cannot be reused directly but can be transformed into new products or raw resources. For example, used paper is recycled into folders, envelopes, and cards.
Recycling recovers energy through the following processes: pyrolysis (combustion of waste in the absence of oxygen to produce gases, liquids, and solid compounds), incineration (combustion in the presence of oxygen to produce oxidised compounds), anaerobic digestion, gasification, and pelletisation, and composting.
