POWER
PLANT OPERATION
In addition
to manufacturing
wood products,
SDS produces power
in its steam -
operated power
plant. Energy created
by SDS qualifies
as bioenergy - energy generated
from renewable, organic resources.
Examples of renewable
energy systems
include solar,
wind, geothermal ,
and biomass energy.
Biomass resources
include any organic
matter, available on a
renewable basis, that
can be used to
provide heat, make
fuels, or generate
electricity. The
residual waste
wood that is burned
in our boiler
and converted
into steam
is a classic example
of biomass.
Bioenergy ranks second (to hydropower) in renewable U.S. primary energy
production and accounts for 3% of the primary energy production in the
United States. Most of the energy used today -- approximately 85% -- is
created with fossil fuels. Fossil fuels, which include oil, natural gas
and coal, do not regenerate quickly to keep pace with demand. Furthermore,
emissions from fossil fuels systems are more polluting than renewable
energy systems. Not surprisingly, there is an urgent push worldwide to
generate renewable, environmentally friendly energy, such as the bioenergy
produced at SDS.
We take great
pride in knowing that 100% of the wood that enters the SDS mill has value
and a purpose. Nothing is wasted. Though our state-of- the art mill uses
the latest in technology to maximize the amount of lumber and veneer recovered
from a single log, leftover residues inevitably exist. We sell sawdust
and wood chips to paper companies and use bark and other wood waste -
biomass - to fuel our steam plant.
Constructed
in 1978, the steam plant supplies the steam required by our lumber dryers,
veneer dryers, log vats and plywood presses. When there is a surplus of
steam, we convert the energy into electricity. The electricity is used
on site or sold to the open market as "green power." Currently,
when running at full capacity, we generate 8.5 megawatts of electricity
per hour with our surplus steam. One megawatt of electricity supplies
an average of 1000 households. Due to today's high demand for power, we
have been busier than ever selling power to the open market. Our biggest
problem with running at full capacity is maintaining a sufficient hog
fuel (biomass) supply. Lately, we've been supplementing our hog fuel supply
with waste wood purchased from other lumber companies as well as waste
wood purchased from recycle yards.
| In
1998 SDS invested in an electorostatic preciptator, a device that
eliminates particulate emissions and guarantees that we meet or exceed
clean air standards. |
