Introduction
Any material that is discarded ,useless or

Waste management is the collection, transport
, processing, recycling or disposal and
monitoring of waste materials
TYPES OF WASTESA. Generation and Characteristics
Municipal Solid Waste
Industrial Solid Waste
Agricultural Waste and Residues
Hazardous Waste
Nuclear Waste
5
Municipal solid waste Municipal solid waste (MSW) is generated from households,
offices, hotels, shops, schools and other institutions. The major
components are food waste, paper, plastic, rags, metal and
glass, although demolition and construction debris is often
included in collected waste, as are small quantities of
hazardous waste, such as electric light bulbs, batteries,
automotive parts and discarded medicines and chemicals.
6
Industrial Solid Waste
 Industrial solid waste in the Asian and Pacific Region, as
elsewhere, encompasses a wide range of materials of varying
environmental toxicity. Typically this range would include
paper, packaging materials, waste from food processing, oils,
solvents, resins, paints and sludges, glass, ceramics, stones,
metals, plastics, rubber, leather, wood, cloth, straw, abrasives,
etc.
7
Agricultural Waste and Residues
 Expanding agricultural production has naturally resulted in
increased quantities of livestock waste, agricultural crop
residues and agro-industrial by-products.
8
Hazardous Waste
 A hazardous waste is waste that poses substantial or potential
threats to public health or the environment. There are four
factors that determine whether or not a substance is hazardous:
 ignitability (i.e., flammable)
 reactivity
 corrosivity
 toxicity
9
Nuclear Waste Nuclear waste is the radioactive waste left over from nuclear
reactors, nuclear research projects, and nuclear bomb
production. Nuclear waste is divided into low, medium, and
high-level waste by the amount of radioactivity the waste
produces.
10
How solid waste management is done?
(a) Collection and Transfer
 door-to-door collection
 indirect collection - containers, communal bins placed
near markets, in residential areas and other appropriate
locations.
11
Municipal Solid Waste/ Industrial Solid Waste
(b) Material Recovery, Reuse and Recycling
Recycling involves processing used waste materials into new
products to prevent waste of potentially useful materials,
reduce the consumption of fresh raw materials, reduce energy
usage, reduce air pollution (from incineration) and water
pollution (from landfilling) by reducing the need for
"conventional" waste disposal, and lower greenhouse gas
emissions as compared to virgin production.
12
(c) Disposal Methods for MSW/ISW
Open Dumping
Land filling
Incineration
13
Open Dumping
 Most widespread
method of solid waste
disposal
 Uncontrolled disposal of
waste without measures
to control leachate, dust,
odor, landfill gas or
vermin.
 Open burning of waste
is practiced at
dumpsites.
 Waste is dumped along
the shoreline and into
the sea.
Drawbacks :
 scarcity of available land.
 build-up of landfill gas
(predominantly methane),
which can led to outbreaks
of fire and adverse health
effects on workers and
adjacent residents.
14
Bio-Medical Waste
 ‘Bio-medical waste’ means any
solid and/or liquid waste including
its container and any intermediate
product, which is generated during
the diagnosis, treatment or
immunization of human beings or
animals or in research pertaining
thereto or in the production or
testing thereof.
 It differs from other hazardous
waste because of its source of
generation.
15
Landfilling
 disposal of waste materials by burial
 Its impacts includes,
- fatal accidents
- infrastructure damage
- pollution of local environment
- Off gassing of landfill gas (Methane)
- harboring of disease vectors
16
Effects on environment and human health
 Computer wastes that are landfilled produces contaminated
leachates which eventually pollute the groundwater. Acids and
sludge obtained from melting computer chips, if disposed on
the ground causes acidification of soil.
 Incineration of e-wastes can emit toxic fumes and gases,
thereby polluting the surrounding air.
 Improperly monitored landfills can cause environmental
hazards.
 The most dangerous form of burning e-waste is the open-air
burning of plastics in order to recover copper and other metals.
17
Uses of solid wastes
Anaerobic digestion
 Anaerobic digestion is a series of processes in which
microorganisms break down biodegradable material in the
absence of oxygen, used for industrial or domestic purposes to
manage waste and/or to release energy.
 Anaerobic digestion is widely used as a renewable energy
source because the process produces a methane and carbon
dioxide rich biogas suitable for energy production, helping to
replace fossil fuels. The nutrient-rich digestate which is also
produced can be used as fertilizer.
