I recently heard someone say they were saving trees by rolling up their old newspapers to burn in the fireplace. The problem with that plan is that the only way newspaper can burn effectively is to machine compress them, and the energy required to do that takes away the green advantage. Otherwise, it burns too hot and fast which can damage the flue, not mention the ash it throws into the air. So recycle the newspapers.
For a green fireplace try using manufactured logs—they burn cleaner than wood logs. To minimize wood smoke pollution from your fireplace or woodstove, light it correctly. Burn only dry, seasoned wood. Start a small fire using softwoods, and add larger hardwood logs once the fire gets going. Remember, excess smoke is a sign that your fire wasn’t lit properly and isn’t burning correctly.
