A short lecture on the basics of recycling and waste as source of fuel and electricity.

1. Waste to Energy
By Arfel L. Tayona
Better Philippines

2. Waste to Energy
• Is the process of using
or converting waste
into fuel for energy
generation

3. Waste as Fuel…
• Solid waste are
flammable and thus
can be used directly
as fuel…
• Waste are
composed of high
energy molecules
and can be
converted into
useful FUEL

4. Waste into Fuel…
Biomass Plastics

5. Plastics as
Fuel
Most Artificial
Plastics are made
from Fossil Fuels
1. Petroleum
2. Hydrocarbon
3. Monomers
4. Polymers

6. Plastics as Polymers
Petroleum Fuels (Gas) Plastic Polymers

7. Combustion
The process of burning
Combustion occurs in the
presence of Oxygen
Converts Organic compounds
to CO2 + Water + Heat

8. The Fire
Triangle
Fire needs:
1. Heat
2. Oxygen
3. Fuel

9. Question and Answer

10. Pyrolysis…

11. Pyrolysis Process
Chemical Process Products

12. Biomass
Pyrolysis
Machine
Converts Waste into Fuel

13. Pyrolysis
Reactor
Limits the entry of Oxygen in
order to limit total combustion
and maximize Molecular Bond
Breakage…

14. Fossil Fuel
Are shorter string
of energy rich
hydrocarbon

15. Question and Answer

16. Sweden
Has such an
effective waste
disposal and
recycling program
that they now
import solid waste
from Norway

17. Waste as Fuel
Solid waste can be combusted
directly into Electricity

18. Why Then…
Why is plastics not widely used
as Fuel for electricity…

20. Question and Answer…
