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

reduction which is an important method of waste management.The
modern concepts based on the three &s are: &educe,
&euse and &ecycle.$ethods of avoidance include reuse of
second hand products, designing products to be refillable or
reusable, repairing bro#en items instead of buying new

COLLECTIONWASTE COLLECTION7rom individual houses, wastes can be
collected in person with the help of vehicle. 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,
