Waste management is the collection, transport, processing, recycling or disposal and monitoring of waste materials.The two conventional principles of waste management were: Dilute and disperse or concentrate and contain.The main necessity of waste management is to enrich the resources which are being depleted due to rising population and increasing consumption rates.INTRODUCTIONINTRODUCTIONHEALTH IMPACTS OF SOLID WASTEHEALTH IMPACTS OF SOLID WASTEEposure to ha!ardous waste can affect human health, children being more vulnerable to these pollutants."mproperly operated incineration plants cause air pollution and improperly managed and designed landfills attract all types of insects and rodents that spread disease.Direct handling of solid waste results in chronic diseases with the waste wor#ers and the rag pic#ers being the most vulnerable.STRUCTURE OF MUNICIPAL STRUCTURE OF MUNICIPAL SOLID WASTESOLID WASTE $%W&efuse Trash 'ul#y wastes (T), refrigerators goods,'ro#en furniture, etc.*

To minimi!e the time and cost involved in collecting waste through vehicles, public can be given instruction to dump their house wastes in one place (nearby their street*. SEGREGATIONSEGREGATION%egregation of wastes into degradable and non-degradable wastes is to be done to recover or divert non-degradable wastes (electric items, plastics, tyres etc.* and degradable items (wood, tetiles etc.* to its recycling plant and if possible, it can be reused."t is a tedious process which therefore needs labour. $agnets can also be used to segregate ferrous metals.This process will help in reducing the amounts of waste going for composting and also earns money (through selling wastes to recycling plant.RECYCLINGRECYCLINGThe non-degradable and degradable wastes can be recycled very economically in the recyclingplants..part from sending wastes to recycling plant, recycling of some organic waste is possible.%ome of the waste recycling techni8ues are: 7ly ash, 0rganic wastes, %lag and scrap, "ndustrial gases,Waste waters, &ecovery of silver from photographic films.SHREDDING OR PUL,ERI+INGSHREDDING OR PUL,ERI+ING This process involves in si!e reduction of organic wastes before it goes for composting.This process reduces the overall volume by 9:;. .D).2T.+E%:"t will increase surface area availability for bacterial activity (decomposition*.7acilitates easy handling of moisture content and aeration.COMPOSTINGCOMPOSTING.erobic composting is one of the cheapest and easiest methods that are being available for $%W.+enerally, composting can be carried out in three techni8ues.
