What are they?:
Eco Blocks
are an all wood product that is simply clean, dry sawdust and shavings
that have been mechanically compressed to form a solid log.
Eco Blocks offer many
benefits over natural firewood because they are a manufactured product,
i.e. they are subject to stringent quality controls during production.
How are Eco Blocks
made?:
Eco Blocks are
made by subjecting suitable raw material to extremely high pressure and
elevated temperature in a die. This cause the natural resins in the
wood to soften, allowing them to flow. The result: the particles bind
together to form a solid wooden extrusion.
Because excess moisture inhibits this process, the raw material must be
carefully dried prior to manufacture. The lack of moisture in the
finished product leads to a very dense, highly bound log with extremely
good burning characteristics.
Why Buy Eco Blocks?:
Eco Blocks
are a new product that can be safely used as a concentrated fuel source
in all open fireplaces, wood burning heaters and combustion stoves.
As there are no chemicals,
additives or binders used to hold the Blocks together, they can also be
used as BBQ fuel.
Eco Blocks
contain only ~9% moisture, whereas "dry" firewood (sold in bulk or
bags) may contain as much as 25% ~ to 30% moisture. Because of the
lower moisture levels, Eco Blocks
radiate more heat on a weight for weight basis than natural firewood.
The reason, energy is spent evaporating off the higher levels of
entrained water in natural firewood, thereby lowering the overall heat
value.
With Eco
Blocks, greater than 90% of the mass of the log is
available as useful heat.
Eco Blocks
are also denser than most naturally occurring firewood. The
manufacturing process ensures that the raw material is highly and
uniformly compacted. This means that you burn fewer Eco
Blocks than natural firewood to achieve the same
heat output.
In short, there can be as
much as 2~3 times more heat energy contained in an Eco
Blocks than an ordinary piece of firewood of
equivalent mass.
Eco Blocks,
due to their regular shape and convenient packaging are easier to store
and occupy less than 1/4 of the space that an equivalent load of
traditional firewood would require. (An important issue where there is
limited storage space available.)
With each Eco
block you can expect a clean, hot burn
(depending on heater controls and settings) with very little ash
residue and lower particulate emissions.
From an environmental
perspective, Eco Blocks utilise
waste material that would otherwise be going to landfill or burned in
an uncontrolled manner. Their purchase also prevents the unnecessary
felling of plantation timber for use as firewood and preserves habitat
for Irish fauna.
Note:
As Eco Blocks are manufactured
from clean, contaminant free, 100% recycled timber, they will last in
storage for long periods of time. However, as with all timber, they
must be stored in a dry place.
