摘要

In early times population was less and the amount of land available for the assimilation of wastes was large hence the disposal of waste did not pose any problem. As the human beings began to congregate in tribes, villages and communities, disposal of wastes became a problem.rnAs living standards increase, the quantity of waste generated also increases, which, in turn, makes waste disposal more troublesome. As a result, waste treatment systems have been developed over the last 50 years. In addition, waste collection, incineration, landfilling, and wastewater treatment have become common practices in industrialized parts of the world. The increasing concern for waste management and disposal parallels an increased appreciation of the concept of humans as custodians of the environment In technological society, solid wastes are generated at every step in the process as the raw materials are converted to goods for consumption. Though industrialization helped in providing many facilities for human kind and prosperity of national economy, the negligence and lack of forethought of planners led to environmental degradation. Although the nature has the capacity to dilute, disperse, degrade, absorb otherwise reduce the impact of unwanted residues in the atmosphere, in the waterways, and on the land, ecological imbalances have occurred when the natural assimilative capacity has been exceeded.
