Biomass refers to plant-based materials that can be used as an energy source. It is one of the oldest sources of energy known. Biomass energy is created from materials that are or once were living plants. Common types of biomass include wood, crop waste, and animal waste. Biomass can be burned directly to produce heat or can be processed to produce other forms of energy like electricity or liquid fuels. The document provides examples of how biomass is used to produce steam to power turbines and generate electricity, as well as how methane gas captured from the decomposition of organic waste can also be used as an energy source.

4. Biomass is the oldest source of energy

5. As a fire burns down, it gets hotter

6. Heat can be used to cook, boil water

7. We can use fire to make steam,
and make steam do work for us

13. What is this?
How much of this do you eat?

14. Rice

15. Rice husk
1 bowl = 1000 grains of rice
1 bowl per day
x 365 days per year
= 365,000 grains of rice per year

36,500 grains per kg
= 10 kg per year per person
13,000,000 people in Manila
x 10 kg per person
= 130,000,000 kg

16. Farmers often burn their
crop waste to get rid of it

17. How can we stop this?
Biomass Power!

18. Grown Biomass
= Energy Crops

19. Seedlings

20. Where do these trees grow?

27. If I cut a tree, is it dead?
No, it can
Coppice
This tree is about 400 years old!

28. Where is this?
Pasay Road, Dasmariñas Village

30. Biogas
from Poop to Power

31. Farms can be dirty places

32. Making food can leave
behind a lot of nasty waste

33. Food or animal
waste ferments in
the pond, releasing
methane gas
Methane is
highly
flammable!!

34. How to Capture Biogas
Thick rubber sheets Methane gas builds up
cover the pond under the rubber sheet

35. Tank type
biogas plant
Power Generator
Biogas Capture
Tanks
Methane Gas Pipe

36. Humans also generate lots of waste!
Covered landfills capture methane like a
balloon
This methane can be used to generate electricity
