Innovations in Waste Management

Shorter Version - A simple and elegant presentation on a few of the latest technologies and policies in waste management.

1. Innovations in
WASTE MANAGEMENT

2. INTRODUCTION

3. What is waste
management?

4. Waste management in simple words means
collecting waste products, transporting it and
processing it into a new product or decomposing it for
good

5. LANDFILL INCINERATOR
conventional METHODS
OF WASTE MANAGEMENT

6. COMPOSTING

Mechanical TREATMENT
And Recycling

7. PYROLYSIS GASIFICATION

8. Rapid development and
industrialisation

Increase in population
Increase in waste generation
Many landfill sites reaching
capacity
THE NEED FOR innovative
WASTE MANAGEMENT

9. New types of waste such
as e-waste or WEEE
becoming new threats
dumped by developed
nations in developing
nations; violation of human
rights
Price of land significantly
increase
Increase in pollution due to harmful emissions and
contaminated and littered water bodies

10. NEW TECHNOLOGIES AND
ALTERNATIVE SOLUTIONS

11. LANDFILL BIOREACTOR
'Controlled land filling'
process
controlled additions of liquid
and leachate recirculation
accelerates the decomposi-
tion process of waste
enhances the growth of the microbes responsible for waste
decomposition

12. Conventional landfills
keep waste as dry as poss-
ible; delays decomposition
covered with plastic
membrane to prevent
escape of land fill gas
Reliable energy generation
reduced pollution threat; reduction of greenhouse gas
emissions
landfill life extension; reduced post-closure maintenance

13. MICROWAVE PLASMA GASIFICATION
organic and other waste heated
by microwaves- heavily ionises;
forms plasma cloud
organic substances are combusted
and transformed into a syngas;
gas provides enough energy to
power microwaves
only 20% of the recovered energy

14. metals, glass and minerals not gasifiable; melted into an
inert slag residue
recyclable by-product; building material; very light;
mouldable

60% more efficient; can produce diesel from waste; produce
70% diesel as a by-product

15. Strains of bacteria capable of breaking
down plastics into biodegradable
polymers
Isolated from soil samples collected
from recycling plants
Polyhydroxyalkanoates (PHAs) synthesized by
bacteria in high carbon sources or nutrients e.g., nitrogen,
phosphorous, sulphur, oxygen
PLASTIC DEGRADING BACTERIA

16. Plastic carry bags, blood
bags and plastic granules
completely degraded
Similar properties to poly-
Ethene and polypropylene
PHAs an environment friendly alternative to petrochemical
-based plastic
Applications in packaging, coating materials, medical equip-
ments

17. No trash sent to landfills, incinerators, etc.
smarter designs for products; to
become resources
New rules and policies- responsible
approach to using and conserving
natural resources

change in attitudes, lifestyles and practices
ethical, economical, efficient and visionary; creates jobs
ZERO WASTE PHILOSOPHY
