Biomass is organic matter from plants or animals that can be burned or processed to create energy. It includes crops grown for energy production, agricultural and industrial waste, and garbage. Biomass can be burned to produce electricity or hot water, or converted into liquid biofuels like biodiesel. While a renewable resource, biomass still produces some pollution and large quantities are needed due to its lower energy output compared to fossil fuels.

2. What is biomass?
 Biomass is the set of organic matter from an
animal or vegetable origin after a natural or
artificial transformation.
 It comes from:
– Crops grown specially to produce energy.
– Waste products from agriculture and industry.
– Rubbish.

4. Uses
 Burned to produce energy (electricity
or hot water).
 Converted into a liquid called a
biofuel; one type is biodiesel, which
is used in cars.

7. More advantages
 It is renewable energy source.
 It does not increase global warming.
 It uses waste products.
 It is a cheap and readily available source
of energy.

9. More disadvantages
 It is less polluting than fossil fuels,
but it can still produce atmospheric
pollution.
 The amount of energy produced is
quite small so large amounts of
biomass are needed.
