This document discusses bioremediation and waste management. It begins by introducing bioremediation as a technique using microorganisms to remove pollutants from contaminated sites. It then discusses the advantages of bioremediation including being cost effective and environmentally friendly, and the disadvantages such as being time consuming. The document also discusses different methods of waste disposal including landfills, composting, and incineration. It covers the waste management hierarchy and principles of the Basel Convention to minimize hazardous waste.

2. OVERVIEW
 Introduction of Bio Remediation
 Advantages & Disadvantages
 Impact on Biodiversity
 Waste Management
 Types of Disposal
 3R’s and Basel Convention

3. 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.

4. ADVANTAGES OF BIO REMEDIATION
 Cost Effective
 Bioremediation is a natural process
 Environment Friendly
 Less Energy and Supervision
 Low Capital Expenditure

5. DISADVANTAGES
 Time Consuming
 Heavy Metals like Cd,Zn not Removed
 Does not Remove all types of Contaminants
 Soil must have High Permeability

7. 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

10. SOLID WASTE DISPOSAL
 Landfills
 Composting
 Incineration
 Recycling
 Reusing ( Domestic Waste)

12. LIQUID WASTE DISPOSAL
 Sedimentation & Dewatering E.g.: Water
Purification
 Bio Remediation E.g.: Oil Spills
 Filtration

13. GASEOUS WASTE DISPOSAL
 Electrostatic Precipitators or ESP
Wet Scrubbers

15. oMinimize generation of hazardous waste.
oEnsure adequate disposal facilities are available
oControl and reduce international movements of hazardous waste
oEnsure environmentally sound management of wastes
oPrevent and punish illegal traffic

16. 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.
