Climate impacts
Bio-fuel areas are re-grown in a near future and
during this growth the same amount of carbon dioxide that
was released in the combustion is bound. That is if the
re-growth of forests is equal to the harvested amount.
Bio-fuels from the forest are renewable and carbon dioxide
neutral; as opposed to the large increase in carbon dioxide
to the atmosphere from the combustion of fossil fuels (oil
and coal for example). The carbon dioxide released during
combustion of bio-fuels causes no net increase in carbon
dioxide concentration in the atmosphere; the same amount of
carbon dioxide was taken up by the trees during their growth
as was released.
The energy input required to harvest and manage bio-fuel
from the forest is very small, less than 5% of the energy in
the harvested bio-fuel is consumed. Provided that the
re-growth of forest is at least equal to the removal, the
climate impact is negligible.
If the ashes are returned to the forests the nutrient cycles
are closed.
The nutrients that was taken up by the trees and removed
from the forest are returned to the soil and become
available to trees. In addition the natural resistance of
the forests against acidification is preserved. In cases
where lime is distributed along with the ashes the pH levels
that we had in the forests before soil acidification
affected Sweden are restored.
Nutrient balance in a forest depends on contributions by
deposition and weathering and losses by leaching and harvest.
If losses are greater than the increases for a nutritional
substance is a negative balance.
Only tribal harvest negative nutrient balances for one or
more nutrients in a majority of the Swedish forest area. At
the abstraction of GROT compared with only ordinary losses
up to twice the amount of calcium, tripled for the potassium
and magnesium, and four-to quintupled for phosphorus.
