BiomassA sustainable source of
energy
Grant Hauber
Biomass is any living plant matter
Biomass energy is energy made from something
that is or once was plant matter
Types of

Biomass is the oldest source of energy
As a fire burns down, it gets hotter
Heat can be used to cook, boil water
Harnessing fire to make steam
Biomass
High Heat
Boiler
Steam
Steam spins the turbine blades
Turning Biomass into Electricity
Rotating magnets create electricity
Pipes filled with water are heated to make steam
Inside a biomass steam boiler

What biomass can you burn to make fire?

What is this?
How much of this do you eat?
Rice
Rice husk1 bowl = 1000 grains of rice
1 bowl per day x 365 days per year
= 365,000 grains of rice per year
365,000 grains of rice 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
Rice husk mountain!
Farmers often burn their crop waste to get rid of it
How can we stop this?
Biomass Power!
Grown Biomass = Energy Crops

Bringing it all together…with no waste!Electricity and Steam are used by the Paper
Mill
Biogas
Farms can be dirty places
Making food can leave behind a lot of nasty waste
Food or animal waste ferments in
the pond, releasing methane gas
Methane is highly
flammable!!
Humans also generate lots of waste! Covered landfills capture methane like a balloon
This methane can be used to generate electricity
Biogas Capture Process
Thick rubber sheets cover the pond
Methane gas builds up under the rubber sheet
Tank type biogas plant
