The global warming measures by MiraCarbon
Global warming is caused by greenhouse gas such as carbon dioxide as the
causative agents.The greenhouse gas concentration on the atmosphere can
be reduced by suppressing the greenhouse gas generation.
MiraCarbon water purification material installed on waste water treatment
facilities,lakes,rivers and sea can absorb and suppress greenhouse gas.

Absorption of Carbon Dioxide
Carbon dioxide is an essential gas to the earth material circulation,it
also supplies the plants oxygen and helps its growth.Therefore it is important
to have mitigation measures on carbon dioxide not only to suppress its
generation.In order to increase the circulation function of oxygen,absorption
from trees and plants is important.
The increase of artificial carbon dioxide by humans will dissolve in the
sea but it will make the seawater acidic and will strongly interfere the
carbonated calcium that makes the bones and shells of the sea organisms,
giving a negative effect on sea life.Therefore,phytoplankton and seaweed
absorption is necessary.Photosynthetic plants in shallow waters that can
be easily reached by sunlight can absorb carbon dioxide through photosynthesis,
fixing the carbon and will release oxygen. |
★Seaforest restoration projects by MiraKombu
| In recent years,the waters of the coastal areas due to the progress of
urbanization and farmland development on the inlands has made it difficult
for earth minerals to flow into the sea because dams and riverbanks were
built.Minerals are provided by the forest but with unplanned deforestation
and forestry and without care,the forest are left devastated.If the minerals
from the forest will not reach the sea,seaweeds can not breed and will
also reduce photosynthesis function. From this situation,regenerating the
seaforest by increasing the seaweeds can help the sea increase its circulation
function abilities and be a global warming countermeasure.The regeneration
of the seaforest will increase the habitats of the fish which is the seagrass
and will lead to the improvement of marine ecosystems and our marine resources.

CarbonFiber a material made from carbon with high biological compatibility
with its large surface can easily attract and attach seaweed implantation
and spores.It also has characteristics that once the seaweeds had attached
is is difficult to remove.That is why installing MiraKombu in the sea will
attract and attach spores and will grow as seedlings.And if there are no
spores or less spores on the sea,placing seed thread seaweed to MiraKombu
will germinate seaweeds. Seaweeds will grow and will construct the sea
forest.
And because of the biological compatibility of MiraKombu,fishes will be
attracted to lay their eggs,making MiraKombu as their habitats.Seashells
will prefer MiraKombu as well.The seeds and saplings of shellfish such
as oysters and sea squirts and their eggs will grow early and the growth
will be big. CarbonFiber combined with iron will elute iron minerals due
to the difference in electro negativity, algaes will grow and will give
a positive effect such as productivity of fish and marine resources. |

Dinitrogen monoxide (N2O) generation suppression
| Organic matter treatment, such as in public sewage treatment facilities
and livestock waste water treatment facilities are generally carried out
by the activated sludge method. Organic matter with aeration in activated
sludge treatment tankwill be decomposed. Ammonia nitrogen in the waste
water will be nitrified by nitrifying bacteria activated by aeration will
change nitrite NO2 to nitrate NO3. Nitrite NO2 and Nitrate NO3 will accumulate
in the tank and dinitrogen monoxide N2O will occur. Biological nitrogen
treatment process in waste water facilities that uses anaerobic tanks will
decompose nitrate NO3 to nitrogen N2 but by doing this dinitrogen monoxide
N2O will occur. Furthermore, dinitrogen monoxide N2O will also generate
from the waste sludge on the aeration tank and sludge in anaerobic condition
will generate methane CH4. |
 |
The mechanism of dinitrogen monoxide N2O generation has also been carried
out in the same manner in rivers and lakes. Ammonia nitrogen that flows
on the rivers and lakes will be nitrified by the oxygen in the water, nitrite
NO2 and nitrate NO3 will accumulate.In addition, the presence of NO3 in
agricultural and household waste water accumulated will generate dinitrogen
monoxide N2O.Methane CH4 will occur when the bottom parts of the water
is in anaerobic condition.In order to suppress dinitrogen monoxide N2O,
is to prevent nitrite NO2 and nitrate NO3 to accumulate in the water.To
decompose nitrate NO3 to nitrogen in a biological nitrogen process, it
will require denitrifying bacteria in anaerobic conditions.
In the activated sludge treatment tank, if denitrifying bacteria in anaeroic
conditions are created the reaction of ammonia nitrogen NH4 → nitrite NO2
and nitrate NO3 → nitrogen N2 is promptly carried out, generation of nitrous
oxide is suppressed. To break from nitrate NO3 to nitrogen, the same as
the biological nitrogen processing, it requires the action of denitrifying
bacteria in anaerobic conditions |

★Dinitrogen monoxide generation suppression by MiraCarbon
CarbonFiber water purification material with its large surface area that
adheres microorganisms will decompose and remove nutrients such as organic
matter, nitrogen and phosphorus. CarbonFiber when placed in water will
spread and will make a carbon mass,making the surface area in aerobic condition
with nitrifying bacteria and the inside area in anaerobic state will adhere
denitrifying bacteria.Therefore, ammonia nitrogen is nitrified in the surface
by the nitrifying bacteria will become nitric acid, decomposed from nitrate
to nitrogen and water by the denitrifying bacteria on the inside, nitrogen
is then diffused into the atmosphere. In the CarbonFiber biofilm, nitrifying
bacteria on aerobic conditions, the presence of denitrifying bacteria of
anaerobic conditions, nitrogen decomposition reaction is promptly carried
out, the generation of dinitrogen monoxide, a greenhouse gas can be suppressed.
In the same way, by using the CarbonFiber water purification material, in water purification of rivers and lakes, nitrogen removal, such as ammonia nitrogen and nitric acid in the water is promptly carried out, along with the results of high nitrogen removal effect, greenhouse gas generation of dinitrogen monoxide will be suppressed. |
