This document discusses the disposal of hazardous waste materials. It notes that hazardous waste comes from many sources and can be in different forms, and that more than 400 million tons are produced annually. It outlines rules for managing hazardous waste and the challenges of hazardous waste production, transportation, storage, and different disposal methods like landfills, incineration, and recycling. The goal of hazardous waste management is to minimize harm to human health and the environment.

2.  Hazardous wastes found in different physical states such as
gaseous, liquids, or solids.
 Worldwide, the United Nations Environmental
Programme (UNEP) estimated that more than 400 million tons
of hazardous wastes are produced universally each year.
 Hazardous Wastes (Management & Handling) Rules, 1989
notified Under the Environment (Protection) Act 1986
amended in 2000.
 The management of hazardous waste in developing countries,
with particular emphasis on industrial hazardous waste,
medical waste, and household hazardous waste..

3.  Hazardous wastes make dangerous or potentially harmful
to human health or the environment.
 Hazardous Waste generally generated with the human
activities such as agricultural, industrial, residential,
institutional, municipal, commercial, recreational.
 These wastes are corrosive, inflammable, explosive, or
react when exposed to other materials and also highly
toxic .
 Hazardous waste management deals with minimizing
harmful effects by applying special techniques of
handling, storage, transportation, treatment, and disposal
of hazardous wastes.

4. A hazardous waste is a waste with properties that make it
dangerous or capable of having a harmful effect on human
health or the environment. Hazardous waste is generated from
many sources, ranging from industrial manufacturing process
wastes to batteries and may come in many forms, including
liquids, solids, gases, and sludges.

5. UN Class Number Hazardous characteristics
1 Explosive
2 Gases
3,4 Flammable
5 Oxidizing
6 Poisonous
7 Radioactive
8 Corrosive
9 Toxic

7. • To grant, refuse or cancel HW Authorization
• To monitor HW generating units for ensuring safe storage,
treatment and disposal of wastes
• To analyze the waste characteristics in order to decide its nature
• To approve the design and layout of a proposed TSDF as per SPCB
guidelines

8.  Production ranges from large
industries to individuals.
 Chemicals used for industrial
processes and the significant
rise in use of these chemicals.
 Unwillingness of the industries
to manage the hazardous
wastes due to the heavy
expenses involved.

9.  Transportation requires
precise control to ensure
safe disposal of such
wastes.
 To ensure that the
generator transport their
hazardous waste only in
the specified transport
vehicles.
 The transporters should
train the drivers to handle
the wastes under
emergency situations.

10.  Hazardous waste containers-
containers compatible with the
waste and must be in good
condition and free of leaks.
 Sealing hazardous waste
containers- containers must
be sealed to prevent leakage
and Plastic wrap, other shift
lids are unacceptable.
 Labeling Hazardous Waste
Containers- containers must
be labeled including name,
telephone number, room
number, and exact contents.

11.  Waste disposal is the final step of waste placing hazardous
waste in a dedicated disposal facility.
 The disposal of radioactive waste is defined as the
emplacement of waste that is intended to isolate the waste
from human and environment.
 To prevent or limit a release of potentially harmful substances
such that human health and the environment are protected.
 The effect of climatic conditions, for example, flooding and
freezing accidents on the solidified wastes.

12.  Landfills
 Incineration
 Recycling

13.  The disposal of refuse and
other waste material by
burying it and covering it
over with soil

14.  Incineration is a disposal
method solid organic wastes
are subjected to combustion .
 Convert them into residue
and gaseous products.
 This process reduces the
volumes of solid waste to 20
to 30% of the original
volume.

15.  Recycling is resource
recovery practice that refers to
the collection and reuse of
waste materials.
 The materials from which the
items are made can be
reprocessed into new products.

16. • Increase in strict regulations on the disposal of hazardous
waste.
• Industries can break down dangerous chemical compounds into
less dangerous forms by physical, chemical, or biological
treatment
• Participation at individual level.
• Provisions of concessions by the government to the industries
for treatment and disposal of hazardous wastes.
