II.Characteristics of Hazardous
Waste
• Ignitability:-
-can create fireunder certain
condition
-flashpoint<60 c⁰
eg:-waste oils,used solvents
• Corrosivity:-
-acids or bases
-pH<or=2 or>or =12.5
- if liquid it will corrode steel
• Reactivity:-
-substance that are unstable under
normal condition.
-can cause exploision,produce toxic
fumes,vapours
-pH b/w 2 and 11.5
eg:-cyanide/sulphide,
batteries etc
• Toxicity:-
-harmful when
ingested/absorbed
-leach from waste and pollute
groung water
eg:- lead,mercury etc
III.Listed Hazardous Waste
• F-Listed
• K-Listed
• P-Listed
• U-Listed
F-LISTED
The f -list contains hazardous wastes from non
specific sources,i.e various industrial processes
that may have generated the waste.the list consist
of solvents commonly used in de greasing,metal
treatment bath and sludge,waste water from metal
plating operations and dioxins containing chemicals
or their precursor.
Eg:-
- Benzene
- toluene
K-LISTED
The k- list contains waste generated by specific
industrial process.
Eg:-
i.Waste including wood preservation.
ii.pigment production.
iii.Petroleum refining.
iv.Explosive manufacturing.
v.Pesticide production.
P-LISTED
Consists of discarded commercial chemical product,
off specification chemicals, container residues and
residues from spillage of material.
U-LISTED
The U - list differs from p - list by the quantity at
which the chemical is regulated.
It includes toxic waste such as:-
1.Pesticides applicators.
2.Laboratories.
3.Chemical formulators.
IV.Types of Hazardous waste
• 1. Nuclear waste
• 2. Industrial waste
• 3. Universal waste
• 4. Medical waste
• 5. Household waste
• 6. construction waste
• 7. Electronic waste
Nuclear waste
Industrial waste
Universal waste
Medical waste
Construction waste
Electronic waste
V.Effects of Hazardous waste
Human Health
• 1. Cancer
• 2. Respiratory problems
• 3. Heart disease
• 4. Exposure effects etc
VI.Effects of Hazardous waste on
Environment
• 1.Global warming
• 2.Air Pollution
• 3.Water Pollution
VII.Treatment of Hazardous
waste
There are 5 types by which the hazardous waste can be
treated:-
1.Physical treatment
2.Chemical treatment
3.Thermal treatment
4.Biological treatment
5.Disposal method
1.Physical treatment
It includes:-
1.Filteration and separation.
2.Screening,sedimentation,adsorption,
centrifugation,stripping
3.whenever a wastecontaining liquid and solid
must be treated.
Filteration and separation
1.Filteration is the method for separating solid
particles from a liquid using a porous medium.the
application of filtration of treatment of hazardous
waste fall into the following categories:-
2.Clarification:-method in which suspended solid
particles are less than 100ppm and the aim is to
produce a clear aqueous effluent, which can be
discharged directly or further processed.
3.De watering:- in this method the slurry is
concentrated by the removal of liquids to form a
solid.
2.Chemical Treatment
1.Chemical Methods are:-
i.Chemical precipitation.
ii.Chemical oxidation and reduction
iii.Neutralization
2.Toreduce the hazard of a particular
waste
3.To make thecomplete breakdown of
HW into non -toxic form
Chemical oxidation and
reduction
In these reactions the oxidation state of one
reactant is raised,while the other reactant is
lowered.
Eg:-
this kind of treatment is used for the waste of
1.Sulphide.
2.Cyanide.
3.Many organic wastes such as pesticides and
phenols.
Solidification and stabilization
1.Solidification is the process in which certain
materials are added that leads to the production
of solids.
2.Stabilization is the process by which a waste is
converted to more chemically stable form. It
involves the chemical reactions which transform
the toxic component to a new non-toxic
compound.
3.Thermal treatment
It involves 2 processes
Incineration:`-it is a term commonly used to
describe all systems of burning carried out in a
multi chambered incinerator.
Temperature of secondary chamber:-1100 c
Residence time:-1 sec.
Pyrolysis:-it is the chemical decomposition or
change brought about by heating in the absence of
oxygen.
Temperature:- 425-760 c
Incineration
1.Able to aachieve 99.9% destruction and removal
efficiency to hazardous components in waste
2.Primary products are CO2,Vapour andAsh
3.Sulphur bearing waste gives off SO2,CO2,H2O
when incinerated
4.Byproducts are sometime more harmful
5.Two type of Incinerator
i.Liquid Injection
ii. Rotary Kins
4.Biological treatment
1.Composting
2.Anaerobic and aerobic treatment
Composting
• COMPOSTING:COMPOSTING:
RECYCLING OFRECYCLING OF
WASTE INTOWASTE INTO
ORGANICORGANIC
FERTILIZERFERTILIZER
Aerobic treatment
Aerobic treatment:-under proper conditions
micro organisms grow.they need carbon and
energy source,nutrients such as
nitrogen,phosphorous and a source of
oxygen.
 Temperature and pH must be controlled
 Toxic substances should be removed.
5. Disposal Methods
• 1.The option for disposal include land
disposal,underground disposal and deep well
injection.
• 2.Choice of disposal method should be
based on evaluation of economics and
potential pollution
• 3.To prevent Environmental pollution from
Landfill , itis essential that site selection
are taken into account
VIII.Conclusion
ON the basis of the above study it is recommended
that HW should be produced in aslittle quantities
as possible .The laws andregulation formulatedfor
the treatment and disposal of HW should
bestrictly implemented.They should be recycledor
treated properly and if they are non biodegradable
then disposed in a way that they do not cause any
damage to our Healthand Environment.
