 Classification of Solid
Waste

 Municipal Solid wastes: Solid wastes that include household garbage, rubbish, construction
& packaging materials, etc. and are managed by any municipality.
 Bio-medical wastes: Solid or liquid wastes including containers, products generated during
diagnosis, treatment & research activities of medical sciences.
 Industrial wastes: Liquid and solid wastes that are generated by manufacturing &
processing units of various industries like chemical, petroleum, coal, metal gas, paper etc.
 Agricultural wastes: Wastes generated from farming activities. These substances are
mostly biodegradable.
 E-wastes: Electronic wastes generated from any modern establishments. They may be
described as discarded electrical or electronic devices. Some electronic scrap components,
such as wires, circuits, mobile, computers etc.

 Muncipal
solid waste
generation
in india

 7.2 million tonnes of hazardous waste.
 One Sq. km of additional landfill area is needed 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.
 Solid Waste in India

 In Mumbai (2005) the sewage line is cloged 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.
 Animals dying on streets due to consumption of plastic
bags, which blocks the food movement in their stomach .

 Causes of
increase in
solid waste

Waste management is the
 storage
 collection
 transport and handling
 recycling
 disposal and monitoring of waste
materials.
 Solid waste
management

 Storage:
- Galvanized steel dust bin
- Paper sack
- Public bins
 storage

 Collection
- House-to-house collection
- Collection from the public bins
 collection

 Waste handling and separation involves activities associated with
waste management until the waste is placed in storage containers
for collection. Handling also encompasses the movement of loaded
containers to the point of collection.
 waste is transferred from a smaller collection vehicle to larger
transport equipment
 Waste handling
and transport

1. Dumping
2. Controlled Tipping or Sanitary Landfill
3. Incineration
4. Composting
5. Manure pits
6. Burial
 Method of disposal

 It is the most traditional method of waste disposal.
 Waste is directly dumped into quarries, mining voids or
borrow pits.
 Disposed waste is compacted and covered with soil.
 It is generally used for domestic waste.
 Land Filling

 Incineration is a waste treatment process that involves the
combustion of solid waste at 1000^o C.
 waste materials are converted into ash, flue gas, and heat.
 The ash is mostly formed by the inorganic constituents of the
waste and gases due to organic waste.
 The heat generated by incineration is used to generate electric
power.
 Incineration

Know 3R’s Concept and Justify
Aspects and Issues related to
recycling and composting of
municipal solid waste (MSW).
 How can we make a
change

Reduction
• By reducing, consumer and industry can save natural resources
and reduce waste management costs.
Reuse
• Large production companies such as Electronic, appliances and
gadgets, should establish the collection centre, where damaged
items can be repaired and reuse.
Recycling
• Recycling turns materials that would otherwise become waste
into valuable resources.

 Waste generation and waste reduction reflect many complex economic and social factors. No city or
town can adopt recommendations in a vacuum; each must examine its own wastes, and the potential
for extending waste reduction.
