    • Solid Waste Management
    • Presented By – Akanksha Singh Enrollment No.- 35 M.B.A GENERAL 2 nd Semester A Course Instructor- Ms.Anviti Gupta Ms.Rekha Khosla
    • Waste- Definition & Classification
      • Any material which is not needed by the owner, producer or processor.
      • Classification
      • Domestic waste
      • Factory waste
      • Waste from oil factory
      • E-waste
      • Construction waste
      • Agricultural waste
      • Food processing waste
      • Bio-medical waste
      • Nuclear waste
    • Solid Waste
    • Classification of Wastes
      • Solid waste- vegetable waste, kitchen waste, household waste etc.
      • E-waste- discarded electronic devices like computer, TV, music systems etc.
      • Liquid waste- water used for different industries e.g tanneries, distillaries, thermal power plants
      • Plastic waste- plastic bags, bottles, buckets etc.
      • Metal waste- unused metal sheet, metal scraps etc.
      • Nuclear waste- unused materials from nuclear power plants
    • Solid Waste in India
      • 7.2 million tonnes of hazardous waste
      • One Sq km of additional landfill area every-year
      • Rs 1600 crore for treatment & disposal of these wastes
      • In addition to this industries discharge about 150 million tonnes of high volume low hazard waste every year, which is mostly dumped on open low lying land areas.
      • Source: Estimate of Ministry of Environment & Forest
    • Growth of Solid Waste In India
      • Waste is growing by leaps & bounds
      • In 1981-91, population of Mumbai increased from 8.2 million to 12.3 million
      • During the same period, municipal solid waste has grown from 3200 tonnes to 5355 tonne, an increase of 67%
      • Waste collection is very low for all Indian cities
      • City like Bangalore produces 2000 tonnes of waste per annum, the ever increasing waste has put pressure on hygienic condition of the city
      • Source: The Energy & Resources Institute, New Delhi
    • Waste Collection in India
      • Primarily By The City Municipality
      • -No gradation of waste product eg bio-degradable, glasses, polybags, paper shreds etc
      • -Dumps these wastes to the city outskirts
      • Local Raddiwala / Kabadiwala (Rag Pickers)
      • -Collecting small iron pieces by magnets
      • -Collecting glass bottles
      • -Collecting paper for recycling
      • MCD- Sophisticated DWM (Delhi Waste Management) vehicle
    • How Solid Waste Affected Us In Recent Years?
      • Cloudburst in Mumbai (2005) clogged the sewage line due to large no. of plastic bags
      • Blast in the Bhusan Steel factory at Noida, caused due to imported scrap from Iran
      • Reduction in the number of migratory birds due to consumption of contaminated foods
      • Stray animals dying on streets and farmland due to consumption of plastic bags, which blocks the food movement in their stomach
    • Hazardous / Toxic Waste & Dumping Site
      • Industrialized countries have waste management problems
      • Developed countries have strict environment regulation norms
      • Most attractive option for them- to dump into developing countries
    • Philadelphia’s Municipal Waste
      • 16 Years Journey For The Cargo Ship To Eleven Countries And Four Continents
      • 25,000 Tones Of Fly ash Came Back To Philadelphia’s Garbage Dump
      • Several Government Refused Cargo Ships
      • In 2002, Cargo Ship Returned Back To Us
    • Major Polluting Industries in India
      • Around 2500 tanneries discharge 24 million cu m of waste water containing high level of dissolved solids and 4,00,000 tonnes of hazardous solid waste
      • 300 distilleries discharge 26 million kilo-litres of spend wash per year containing several pollutants
      • Thermal power plants discharge huge waste materials
    • Collection & Recycling of Waste Materials
    • Managing Waste
      • Recycling: Processing of a waste item into usable forms.
      • Benefits Of Recycling:
      • -Reduce environmental degradation
      • -Making money out of waste
      • -Save energy that would have gone into waste handling & product manufacture
      • Saving Through Recycling:
      • -Making paper from waste saves 50% energy
      • -Every tonne of recycled glass saves energy equivalent to 100 liters of oil
    • Recycling Not A Solution To All Problems!
      • Recycling is not a solution to managing every kind of waste material
      • For many items recycling technologies are unavailable or unsafe
      • In some cases, cost of recycling is too high.
    • Solution: More Profit With Zero Waste
      • Exchanging output that are considered waste
      • Waste of one could be input or raw material for others
      • Evolving a closed system- matter & energy circulate within
      • System was not designed to be so
      • The system of exchange evolved in 10 years
    • Problems In Dealing With Solid Waste
      • Education & voluntary compliance
      • Collection of waste
      • Technological interventions
      • Institutions & regulatory framework
      • Absence of mandatory standards for waste reduction
      • Market action for waste reduction
