Types of Biomass
Scientists recognize four types of biomass:
- Wood and agricultural products: This consists of
so-called ‘home-grown' products such as wood logs and chips etc. It is
important to note that almost any biological matter can produce biomass
energy. Agricultural biomass come from waste products such as fruit
pits, corn cobs etc.
- Solid waste: This is everyday waste / ‘garbage'
that can be used to produce energy. It is easily burnt and many plants
are already using this method of generating energy.
- Landfill gas: This is methane gas that is produced
during the decaying and rotting process of biological matter. Landfills
are artificial environments for these processes to take place, but are
just as effective in generating gas that can compete successfully with
the so-called ‘natural gasses'.
- Alcohol fuels: Liquid fuels such as ethanol and
methanol are produced using biological matter such as wheat, corn and
potatoes. Once again, this is done during the decaying and fermentation
processes.
Sources of Biomass
There are 5 distinct sources of biomass: Garbage, Wood, Waste, Landfill gases and Alcohol fuels. The biggest source of biomass
currently is garbage. The day-to-day waste of households hold the
biggest potential for biomass energy as it is already habit to
incinerate garbage. Wood comes in at second place with the so-called
‘black liquor' its biggest contributor. Black liquor is the waste
product of the pulping process.
Hot on its heels is waste with it main contributors being municipal
solid waste (MSW), manufacturing waste and landfill gas. In the last
place are the liquid fuels such as ethanol and methanol which are the
result of the fermentation of certain plant types such as corn and
sugarcane. Together these sources of biomass have the potential to
produce significant amounts of energy that could successfully replace
the use of fossil fuels such as coal as a source of energy.
How Biomass energy works?
The process of producing biomass energy starts with the process of photosynthesis in plants.
When plants absorb sunlight, the process starts with breaking down the
components of sun, air and water into products that the plant uses to
grow and thrive. One waste product of the process is oxygen which the
plant releases into the air. This is why plants are so important as they
"clean" the air of carbon dioxide and release oxygen back into the air.
The next step comes when the plant dies and becomes a waste product.
As a waste product plant matter (as well as animal waste) can be
collected and burned to generate energy. Because these products are all
completely natural, the waste product from the incineration process is
carbon dioxide which can easily be absorbed by other, living plants. The
carbon emissions are greatly reduced and in many cases not even
produced.
