3. Introduction
“Hazardous Waste” means the waste the waste that is
danger to health and environment by itself or in combination with other
material.

4. Types of hazardous waste
i]Reactive wastes
ii]Ignitable wastes
iii]Medical waste
iv]Radioactive waste
v]Corrosive waste
1.Reactive wastes-
This wastes are unstable and tend to react vigorously
with air and water and other substances.

5. 2.Ignitable wastes-
This waste burns at low temperature and are
capable of spontaneous combustion during storage, transport or
disposal.
3.Medical waste-
This waste include waste by medical field like hospitals
and biological research centers.

6. 4.Radioactive waste-
This waste includes lionizing radiation and waste from
nuclear power plants.
5.Corrosive waste-
This waste includes waste due to chemical reaction

7. Characteristics of hazardous waste-
i]Ignitability
ii]CorrosivitySSDSFDF
iii]Reactivity
iv]Toxicity
1.Ignitability-
This characteristic of hazardous waste is due to fires
under certain condition.
2.Corrosivity-
The characteristic of hazardous waste due to high
alkaline or acidic waste.
3.Reactivity-
This characteristic gives unstable property to
waste.
4.Toxicity-
It is the degree which substance can damage an

11. Management of Radioactive Waste
i]Ocean dumping

12. Kilometers deep rather than
hundreds of meters.
Provide Further isolation from ground
water.
More potential borehole locations
around the globe.
Can be created in many cases close
to power plants.
Deep bore holes

13. Burrowing nuclear waste into the ground
to the point where it is out of human reach
Large variety of geological environments
suitable for disposal
Depth of burial is very high
Waste can be recovered
Most widely used method
Practically feasible with current
technology
Geological disposal

14. Long term method
Separating useful
components from non
useful
Fissionable material out
from irradiated nuclear fuel
Reprocessing

15. Decay and Storage
Store waste in the laboratory if the half-
life is no more than 120 days.
“DIS” Isotopes must be held for decay for
at least 10 half-lives.
Survey monitoring of material must read
close to background.
All radioactive labeling must be
defaced.
Document in log

16. Management of reactive, ignitable, corrosive waste
Incineration Process
Incinerators are used to dispose or refuse by burning it at
high temperature.
