Treatment and Disposal of Municipal Waste
As cities are growing in size with a rise in the population,the amount of waste generated is increasing becoming unmanageable.The local corporations have adapted different methods for the disposal of waste-open dumps,landfills,sanitary landfills,and incineration plants.One of the important methods of waste treatment is composting.
Open dumps
Open dumps refer to uncovered areas that are used to dump solid waste kinds.The waste is untreated,uncovered,and not segregated.It is the breeding ground for flies,rats,and other insects that spread disease.The rainwater run-off from these dumps contaminates nearby land and water thereby spreading disease.In some countries,open dumps are being phased out.
Landfills
Landfills are generally located in urban areas where a large amount of waste is generated and has to be dumped in a common place.Unlike an open dump,it is a pit that is dug in the ground.The garbage is dumped and the pit is covered thus preventing the breeding of flies and rats.At the end of each day,a layer of soil is scattered on top of it and some mechanism,usually an earth-moving equipment is used to compress the garbage,which now forms a cell.Thus,every day,garbage is dumped and becomes a cell.After the landfill is full,the area is covered with a thick layer of mud and the site can thereafter be developed as a parking lot or a park.
Landfills have many problems.All types of waste are dumped in landfills and when water seeps through them it gets contaminated and in turn pollutes the surrounding area.This contamination of groundwater and soil through landfills is known as leaching.
