Wood Stoves and Firewood
BioBricks: What They Are and Where to Find Them
In James Houston's "The Development of a Firelog With Improved Air Emissions" he
states: "Replacing normal firewood with [densified wood] firelogs can be an effective
means of reducing pollutant emissions from existing fireplaces...Pressed wood firelogs
offer the potential to lower woodstove and fireplace emissions."

Biobrick Heat Content vs Firewood
For comparison purposes I'll use the firewood BTU heat values from the table of
Firewood Heat and Weight Values compiled by the California Energy Commission. The
table lists the cord weight and BTU values for 39 species of firewood at 12% moisture

However, a typical cord of firewood rarely consists of only one species making it
difficult to determine its BTU value. For the sake of simplicity I'll compare the heat value
of BioBricks to Ash which has a BTU value averaging halfway between Live Oak
(highest) and Western Red Cedar (lowest).

The heat value for a cord of 12% moisture Ash is 25 million BTU's at an average weight
of 3,000 pounds. This works out to 8,333 Btu's per pound.

The manufacturer's heat estimate for a single two pound BioBrick is 17,000 Btu's, or
8,500 Btu's per pound – almost identical to Ash.

BioBrick Storage
The stackable nature of bricks makes the most of scarce storage space. One pallet of
BioBricks (4'x4'x3') takes up 60% less space than a cord of wood (4'x4'x8') and
eliminates the mess and hassle associated with handling logs.
BioBrick Availability
BioBricks are sold by the bag or
pallet. The weight and price of a bag
or pallet varies from dealer to dealer.

This shouldn't be cause for concern
cost-wise if you're buying the
occasional bag for your fireplace or
chiminea, but if you're buying by the
pallet for your wood stove, question
#1 to the dealer should be: "How
much does your pallet of BioBricks
BioBrick Cost
Although the standard weight for a pallet of BioBricks is 1,900 lbs and costs around
$300, I have also seen pallets weighing far less than 1,900 lbs sold at the same price.

This season - 2013/14 - prices for a pallet of BioBricks are ranging between $279 and
$349 (cash or check). That's quite a spread. Considering the $70 difference per pallet,
and the wide availability of BioBricks, it might be worth your while to drive an extra 50
miles out of your way - even at today's high gas prices.

Currently, BioBricks are available in Connecticut, Massachusetts, Maine, Vermont, New
Hampshire, New Jersey, New York and Rhode Island from the following

BioBricks and wood pellets are essentially the same product and compete for the
same raw material: sawdust. The same market forces that affect the price of wood
pellets will similarly affect the price of BioBricks. The availability of wood for sawdust,
more than any other factor will determine the selling price.

BioBricks are the latest eco-
friendly home heating
alternative to firewood and
heating oil. Each 2 pound brick
is made from 100% compressed

The extreme density of
compressed sawdust yields
near complete combustion,
longer burning times than cord
wood, and only 1% ash residue.

BioBricks are equally beneficial
to the environment by
producing less carbon monoxide
and half the particulates of
seasoned hardwood.
