New firelogs burn cleaner than gas and cordwood

STOCKTON, Calif. (April, 2007) – A recent report by OMNI Environmental Services, Inc. of Beaverton, OR shows that Duraflame’s new bio-wax/fiber firelogs emit less greenhouse gasses than all other common fireplace fuels. According to Dr. James Houck, the author of the report, burning Duraflame® biowax firelogs can make a significant impact on reducing residential carbon emissions. Houck adds that when compared with cordwood, the new firelogs produce far less particulate emissions, carbon monoxide and other hazardous air pollutants.     

The OMNI study measured the output of the new firelogs in two ways: 1) measuring the carbon output associated solely with the firelogs’ combustion (the primary emissions output), and 2) measuring CO2 emissions associated with the entire “life cycle” of the new logs (the secondary emissions output). 

Emissions from the new Duraflame firelogs are now carbon neutral. This is because every ingredient used in their production is renewable. This method of measurement is consistent with the guidelines for preparation of greenhouse gas inventories by the Intergovernmental Panel on Climate Change and the United States Environmental Protection Agency. According to the 2006 U.S. Greenhouse Gas Emission Inventory Report, carbon dioxide emitted from the combustion of biomass fuels such as wood, charcoal, wood waste, and biomass-based fuels such as ethanol from corn and woody crops does not increase atmospheric carbon dioxide concentrations.  

The second measurement broadens the analytical scope, looking beyond just the carbon impact associated with combustion. The life cycle analysis takes into account secondary C02 emissions (i.e. C02 emissions associated with the manufacturing, handling, and transportation of the firelogs prior to their being burned) and uses that data to calculate a net carbon output attributed to the product.

In its final comparative analysis of fireplace fuels, the OMNI study combines the primary and secondary emissions outputs of different fireplace fuels in order to establish a consistent method of measurement for each different fireplace fuel. On this basis, the Duraflame bio-wax firelogs are the cleanest common fireplace fuel available.

The new Duraflame logs generate 4.3 lbs of CO2-Eq, per single, fireplace fire event (FFE).   Dr. Houck defines a single FEE as a typical fireplace fire ranging from 2.5 to 3.5 hrs. By the same measure, natural gas fireplaces and log sets produce 11.7 and 24 lbs of CO2-Eq respectively, propane gas fireplaces and log sets produce 12.6 and 25.7 lbs of CO2-Eq, and burning cordwood generates 5.5 lbs of CO2-Eq. In contrast, firelogs still made with petroleum-based wax were found to emit 17.5 lbs of CO2-Eq.

“Biowax/fiber firelogs burned in a solid fuel fireplace produce the lowest greenhouse gas emissions among all the current fireplace fuel options,” said Dr. Houck. “These new firelogs reduce greenhouse gas emissions by more than 63 percent over natural gas and by over 82 percent when compared with propane.” 

There are approximately seven million homes that have fireplaces with natural gas or liquid propane log sets installed in the US. If ten percent of those households removed their log sets and converted to burning Duraflame’s new all natural firelogs, it would result in a reduction of approximately 321 million lbs of CO2-Eq each year. That’s equivalent to taking 31,500 automobiles off the roads annually.

There has been a lot of buzz about what people can do to minimize their carbon footprint in order to reduce their impact on climate changes,” noted Caron. “Our new all natural firelogs allow people to enjoy a cozy fire while making a contribution to reducing air pollution and green house gases at the same time. That’s the kind of win/win solution that can motivate more consumers to adopt environmentally friendly lifestyles.”

Duraflame has consistently been the leader in innovation within the firelog market. Three years ago, Duraflame introduced the first non-petroleum wax, the All Natural firelog, which quickly became a top seller.

In 2006, Duraflame began switching over its entire branded product line to non-petroleum wax, with the introduction of its 6lb Xtra firelog in the Western United States. One year later the conversion process is nearly complete. This move puts them in the lead in providing retailers and consumers with a complete product line of renewable firelogs that perform better than traditional, petroleum-based wax firelogs.

Duraflame’s wholesale change to bio-wax for its branded products comes after over 30 years of using petroleum wax, so the change is a major one for the company. Duraflame manufactures over 50 million firelogs per year.
