What is Solid WasteSolid waste means any garbage, refuse, sludge froma wastewater treatment plant, water supplytreatment plant, or air pollution control facility andother discarded materials including solid, liquid,semi-solid, or contained gaseous material, resultingfrom industrial, commercial, mining and agriculturaloperations, and from community activities, but doesnot include solid or dissolved materials in domesticsewage, or solid or dissolved materials in irrigationreturn flows or industrial discharges that are pointsources subject to permit

Components of Solid Waste Management

The municipal solid waste industry has fourComponents: recyc l ing , co m po s t ing , land

f i l l ing,and w aste-to-energy via incin erat ion . The

primary stepsare generation, collection, sorting and separation,transfer, and disposal. Activities in which materials

areidentified as no longer being of value and are

either

RecyclingRecycling is a process to change waste materials intonew products to prevent waste of potentially useful

materials, reduce the consumption of fresh rawmaterials, reduce energy usage, reduce air pollution(from incineration) and water pollution(from land filling) by reducing the need for"conventional" waste disposal, and lower greenhouse

gasemissions as compared to plastic production.

CompostingComposting is organic matter that hasbeen decomposed and recycled as a fertilizer and soil

amendment. Compost is a key ingredient in organicfarming. At the simplest level, the process of

compostingsimply requires making a heap of wetted organic

matterknown as green waste (leaves, food waste) and

waitingfor the materials to break down into humus after a

eriod of weeks or months.

Landfill A landfill site (also known as a tip , dump ,Rubbish dump or dumping ground ) is a site

for the disposal of waste materials by burialand is the oldest form of waste treatment.

Historically, landfills have been themost common method of organized wastedisposal andremain so in many places aroundthe world.

Waste-to-energy

Waste-to-energy or energy-from-waste isthe process of generating energy in the formof electricity and/or heat from the incinerationof waste. WtE is a form of energy recovery. MostWtE processesproduce electricity and/or heat

directly throughcombustion, or produce acombustible fuel commodity, such as methane,methanol, ethanol or synthetic fuels.
