BiomassesBiomassesthat is

as to produce energy from the waste



BiomassesBiomasses are are represented by organic represented by organic

materials (branches, materials (branches, leaves, etc) formed leaves, etc) formed

during the during the photosynthesis.photosynthesis.

But the word But the word biomassbiomass indicates:indicates:

• Waste products resulting from Waste products resulting from agriculture;agriculture;

• Scraps of wood;Scraps of wood; • Waste of agro industry;Waste of agro industry;• Organic fraction of urban waste;Organic fraction of urban waste;• Cultivated plants to energetic power.Cultivated plants to energetic power.



When the When the biomassesbiomasses are are burnt it is obtained burnt it is obtained

energy, nitrogen dioxide energy, nitrogen dioxide and water. These last and water. These last will help the plants to will help the plants to produce new energies.produce new energies.



Burning Burning biomassesbiomasses other substances are other substances are

produced, even if bad, produced, even if bad, but in a quantity but in a quantity

surely inferior to the surely inferior to the combustion of oil or combustion of oil or

coal.coal.



Producing energy from Producing energy from the the biomassesbiomasses it is it is

possible to eliminate possible to eliminate many of the scraps many of the scraps

and the waste and the waste resulting from human resulting from human

activities.activities.



The The biomassesbiomasses are are used for the used for the

production of energy production of energy ((biopowerbiopower) and for the ) and for the synthesis of the fuel synthesis of the fuel ((biofuelbiofuel) besides for ) besides for

home heating.home heating.



Some energy Some energy cultivation (sunflower, cultivation (sunflower, colza….) are used for colza….) are used for

the production of the production of bludieselbludiesel, a mixture on , a mixture on the market similar to the market similar to the characteristics of the characteristics of diesel oil and right for diesel oil and right for

diesel engines.diesel engines.



To produce To produce biomassbiomass energy it is used:energy it is used:

• Their direct combustion ( wood);Their direct combustion ( wood);• Their transformation in gas;Their transformation in gas;• Their transformation in coal;Their transformation in coal;• Their transformation in bio-oil Their transformation in bio-oil

and coal.and coal.



Use the biomasses is advantageous they are available in regard to the request and they preserve intact the

energy until its employment.



The teleheating is the The teleheating is the right solution to exploit right solution to exploit the the biomassesbiomasses because because it gives heat to a group it gives heat to a group of houses or industries, of houses or industries, near to the place of the near to the place of the production of the used production of the used

biomassbiomass (wood, (wood, sawmills, etc…).sawmills, etc…).



Manure and the Manure and the organic part of solid organic part of solid urban waste can be urban waste can be

used as used as biomassesbiomasses in in special systems special systems

(digestori) for the (digestori) for the production of methane production of methane

gas (CHgas (CH44).).



With the exploitation With the exploitation of of biomassesbiomasses::

• We polluted less than with fossil We polluted less than with fossil combustible;combustible;

• We have renewable energy;We have renewable energy;• We save money;We save money;• We free the world from the waste.We free the world from the waste.



BIOMASSES:BIOMASSES:a way toa way to

save our planet!save our planet!
