What are the environmental benefits of using a Burnrite outdoor wood stove?

While less useful in an urban setting (where the smoke is sure to annoy at least one neighbor), in rural or even suburban environments Burnrite outdoor wood stoves can have a positive environmental impact.

First of all, the wood itself is a renewable heating fuel. Proper wood harvesting techniques (found on the EPA website as well as many others) can result in sustainable fuel sources for generations. Harvesting dead fall and naturally fallen timber also reduces the impact on the forest ecosystem, as well as helping to reduce the impact and damage of natural (and accidental) forest fires. Taking naturally fallen or dead wood also reduces the time needed for the wood to season, which is the term for allowing the wood to dry so that you get the most BTUs from the burning as possible, as well as less smoke.

In addition, proper wood burning is also carbon neutral. The burning of wood in an outdoor wood stove will release no more carbon than the wood releases if left to rot on the forest floor. The use of proper harvesting techniques also results in no more carbon being released into the air than would be removed from the air by the maturation of the replacement tree. This is why it is important to not take the smaller, easier to cut trees. Smaller trees that have not properly matured also do not provide the optimum amount of BTUs and usually require more time to season the wood for proper burning. It also takes more time (and chainsaw gas) to make a full cord of wood¹ out of smaller tress than larger ones, making for slower and less efficient harvesting.

¹ A cord of wood in the United States is 128 ft³ or a pile of wood 8 ft wide × 4 ft high of 4 ft-long logs.
