INTRODUCTION
Bioremediation is a waste management technique that involves
the use of organisms to remove or neutralize pollutants from a
contaminated site.
Microorganisms used to perform the function of bioremediation
are known as Bio Remediators.
They are of two types namely In situ ( in site) and Ex situ Bio
Remediation.
It basically encourages the use of pollution eating microbes on the
medium.
Eg: Use of Oil Zappers to feed on oil spills.
ADVANTAGES OF BIO REMEDIATION
Cost Effective
Bioremediation is a natural process
Environment Friendly
Less Energy and Supervision
Low Capital Expenditure
DISADVANTAGES
Time Consuming
Heavy Metals like Cd,Zn not Removed
Does not Remove all types of Contaminants
Soil must have High Permeability

WASTE MANAGEMENT
It is the "generation, prevention, characterization, monitoring,
treatment, handling, reuse and residual disposition of wastes.
Waste can be characterized into Solid, Liquid and Gaseous ( in
terms of the size of the waste).
The Biggest problem of Waste is due to it’s improper disposal. It is
here that awareness about Waste Management comes in handy.
There are distinct ways of disposing different types of Waste

3R’S
This modern concept deals with reusing,
recycling and reducing our waste.
It is most applicable to Domestic Waste.
It is very popular due to it’s Day to Day approach
and easy methodology.
In some places it is also called as 4 R’s with
Refuse being the addition to the existing three.
