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

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.

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.

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

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 organism.

Management of Radioactive Wastei]Ocean dumping

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

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

Long term method

Separating useful

components from non

useful

Fissionable material out

from irradiated nuclear

fuel

Reprocessing

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.

Management of reactive, ignitable, corrosive wasteIncineration Process

Incinerators are used to dispose or refuse by burning it at high temperature.
